The TRXLA3 will lock to and record all standard time code frame rates. 23.98, 24, 25, 29.97DF, 29.97DF, 30 DF, 30 NDF Time Code Source Select TC SOURCE:

ZAXNET (RF) The time code source menu selects how the transmitter will receive its time code. ZAXNET (RF) - The TRXLA3 will receive time code via ZaxNet from a Nomad, a QRX235, IFB100/200, TRX900CL or another TRX transmitter or a ZFR recorder that is transmitting ZaxNet time code. AUDIO INPUT - The TRXLA3, with a proper cable, will receive time code via the microphone input. When time code is connected, it takes the TRXLA3 approximately three seconds to recognize the TC. The screen will display TIME CODE followed by JAM when it is recognized. Please note that when using the microphone input connector, the audio level of the time code signal needs to be between -30 and -10 dBFS on the units meter. Any level above -10 may cause clipping, which will prevent proper reading of time code. TC Jam Mode Select TC JAM MODE:

AUTO-JAM NORMAL This menu controls if the TRXLA3 will go into record when it receives a record run time code. AUTO-JAM NORMAL - The TRXLA3 will continuously jam time code via ZaxNet and will go into record when receiving a record command via ZaxNet or if the unit is put into record manually by pressing the CARD and INC keys simultaneously. AUTO-LOAD REC RUN - In Auto-Load mode the TRXLA3 will go into record when it detects rolling time code, and will stop when the time code stops. If time code is lost because the IFB signal is too weak the unit will not stop but will continue in whatever state it was in until the time code signal is restored. 9 Zaxcom TRXLA3 Time Code Menu Mute Time Code Transmission Until Jammed MUTE TC SEND UNTIL JAMED: OFF If the mute time code menu is set to ON the ZaxNet transmitter will not broadcast time code over ZaxNet until the transmitter receives time code and jams its own internal time code generator. This prevents the ZaxNet from sending incorrect time code to another device. Auto Frame Rate Enable AUTO FRAME RATE ON (23.98) When turned ON the TRXLA3 will automatically set its frame rate to the frame rate that is being transmitted from the ZaxNet transmitter that is feeding the TRXLA3. If auto frame rate is set to OFF the frame rate will need to be adjusted manually. Please note that auto frame rate will only work when the time code is being received over ZaxNet and will not work when time code is being received via the audio input. 10 Zaxcom TRXLA3 Transmit Menu TRANSMIT MENU UHF Transmitter Power Level Set TX POWER: 50MW UHF Transmit Modulation Set TX FORMAT:

OFF Power roll will allow the transmitter to stay in a lower transmit power setting to conserve battery power, and then when triggered the transmitter will increase the output power. OFF - Power roll is disabled and the TRXLA3 will remain at the set power level. DIVA TRIGGER - A command from a Zaxcom recorder will cause the TRXLA3 to go to full power. RECORD TRIGGER - When the transmitter goes into record either manually or from an AUTO-LOAD trigger the TRXLA3 will go to full power. 11 Zaxcom TRXLA3 Transmit Menu Transmitter Disable - Record only mode TX DISABLE :

NORMAL TX MODE Record Only Mode - Will set the TRXLA3 to act as a standalone recorder and will not transmit any audio over UHF. This will conserve battery power since the transmitter is disabled. Normal TX Mode - Will allow the TRXLA3 to both transmit audio and record on its internal SD card. 12 Zaxcom TRXLA3 Record Menu RECORD MENU SD Card Format This menu will only appear if a card was inserted prior to booting up PRESS UP KEY 5X:

TO ERASE CARD The Micro SD card is erased and formatted from this menu. Please note that all cards need to be formatted in a 3 series transmitter prior to recording. Before formatting the card, the transmitter can optionally be renamed (see set up menu). When a transmitter is named that name is included in the recorded file names. By naming the transmitter it makes it easier to differentiate files from different recorders, so for example the card can be identified with the talents name, or any other unique identifier. The card name menu is located at the end of the set up menu. The factory default name is the transmitters serial number. Partial Format If the cards FAT32 file structure gets corrupt while doing a file transfer, and the card is no longer recognized by the transmitter or by ZaxConvert, a partial format can be done. The partial format rewrites the FAT32 file structure and leaves the recorded audio untouched. To do a partial format from this menu press the DEC key 9 times PARTIAL FORMAT will then be displayed. Playback Control STOP 09:18:05:02 SEG 001 Recorded files can be played back from this page. The top line displays the current mode of the recorder: REC, PLAY or STOP followed by the time code. The bottom line contains the current segment number and the audio level. Playing back from the transport page:

Pressing the INC key while stopped will play the segment number that is displayed. Pressing the DEC key while playing back will stop the playback. Pressing the DEC key while stopped will jump back. Holding the INC key will jump ahead one segment. Holding the DEC key will jump back one segment. Pressing the INC key while in play mode will cause the playback to jump ahead, repeated quick presses will cause playback to advance in larger increments. 13 Zaxcom TRXLA3 Record Menu Time Left on Card This menu will only appear if a card was inserted prior to booting up TIME LEFT 20 H TIME USED 4 H This page displays the remaining record time left on the card as well as the time already recorded on the card. Record on boot up allows the onboard recorder to automatically start recording after the transmitter boots up. ON - The onboard recorder will automatically start to record after the TRXLA3 boots up. OFF - The onboard recorder will wait for a ZaxNet command or a manual record trigger to start recording. Automatic Record after Boot up RECORD ON BOOTUP OFF Recording Mode Set RECORD MODE:

LOOP RECORD Low Battery Stop Set LOW BATT STOP:

NEVER STOP Record mode sets what the recorder will do after the card is full. Regardless of this setting the card can only record 500 files. NON-LOOP RECORD - Once the card is full the recording will stop and FULL will be displayed. This setting prevents over-writing any portion of the audio. LOOP RECORD - Once the card is full, the new audio will begin over-writing the oldest audio on the card. Low battery stop will set the amount of time, after a low battery warning occurs, the on-board recorder will close the current file and stop recording. This is to prevent possible file corruption if the unit constantly powers off and on due to a dead battery. NEVER STOP - The onboard recorder will not stop recording unless it is manually stopped by a key press, or when it receives a stop command via ZaxNet or if the battery dies. Any interval from 1 to 99 minutes - Once the battery indicator starts blink a low battery warning the onboard recorder will continue to record for the time set here - then it will close the file and stop recording. 14 Zaxcom TRXLA3 ZaxNet Menu ZAXNET MENU ZaxNet Mode ZAXNET MODE: TX This menu sets the mode of the ZaxNet transceiver. OFF - The ZaxNet transceiver is disabled. The TRXLA3 will not receive ZaxNet commands or time code and it will not send any ZaxNet audio. Please note if ZaxNet mode is set to OFF only the group and unit code menu will be accessible. RX - The ZaxNet transceiver will receive ZaxNet commands and time code. This screen will display what ZaxNet data is being received by the TRXLA3. Including total received information packets, ZaxNet TC received and remote control commands received. This information is used for debugging purposes. TX - The ZaxNet transceiver will send ZaxNet confidence audio and time code. Please note that in ZHD48 mode the TRXLA3 will not be able to go into transmit mode. ZaxNet Receive Frequency Set This menu will only appear if the TRXLA3 is set to receive (RX) mode RX FREQ : 2.403 RX SIGNAL : 28 The ZaxNet receive frequency is the frequency that the TRXLA3 will get its wireless time code and remote control commands on. This frequency will need to match the frequency of the corresponding ZaxNet transmitter. The ZaxNet transmitter can be a QRX with QIFB, Nomad, TRX900CL or IFB100/200. The TRXLA3 can also receive ZaxNet time code from another TRX transmitter or a ZFR recorder that is transmitting ZaxNet on this frequency. Please keep in mind that the range will be limited when receiving ZaxNet from a TRX or ZFR. When the TRXLA3 is receiving a valid ZaxNet signal the signal strength will be shown as well as signal strength meter that runs vertically on the far right side of the screen. ZaxNet Transmit Frequency Set This menu will only appear if the TRXLA3 is set to transmit (TX) mode ZAXNET TX FREQ:

2.473 The ZaxNet transmit frequency is the frequency that the ZaxNet transmitter on the TRXLA3 will broadcast time code and confidence audio on. Please note the ZaxNet transmitted audio is for quality control purposes and the expected range will be less than 20 feet. 15 Zaxcom TRXLA3 ZaxNet Menu Group Code Set REMOTE CONTROL GROUP CODE = 1 Unit Code Set REMOTE CONTROL UNIT CODE = 001 This menu is where the TRXLA3 is assigned to a group. The group code allows transmitters to be grouped together so they can be controlled via ZaxNet without affecting others. So for example a TRXLA3 set to Group 1 will be controlled by a ZaxNet transmitter set to Group 1 and a TRXLA3 assigned to group 2 will be controlled by a Group 2 ZaxNet transmitter. This is helpful if two or more people on set are sending ZaxNet commands. Therefore the different group codes allow each person to be independent and not interfere with each other. Most users leave the group set to 1 on all of their Zaxcom products. Group codes can be set from 1 to 99. This menu is where the TRXLA3 is assigned a unit code. The unit code is a unique number used to identify each TRXLA3 within a particular group. This allows individual transmitters within the same group to be independently controlled. Each transmitter should have a different unit code. Unit codes can be assigned any number from 1 to 200. ZaxNet Voting Enable This menu will only appear if the TRXLA3 is set to receive (RX) mode ZAXNET VOTING:

NORMAL (OFF) The purpose of voting is to allow the ZaxNet receiver in the TRXLA3 to choose, and switch to, the stronger signal from two different ZaxNet transmitters. One purpose of this is if on a large set a second IFB transmitter can be placed at a different location so the ZaxNet receiver in the TRXLA3 can choose the stronger signal. Please note that the second ZaxNet transmitting frequency must be set 2MHz higher than the first ZaxNet transmitter. 16 Zaxcom TRXLA3 ZaxNet Menu ZaxNet Receive Before Transmit Time RX TO TX TIME:

OFF (NORMAL RX) ZAXNET RX TO TX:

0 SEC: TX ONLY ZAXNET RX TO TX:

20 SEC Receive only mode. The ZaxNet transceiver will only receive ZaxNet and NOT go into transmit mode. Therefore no ZaxNet TC and/or audio will be transmitted. This setting shuts off the ZaxNet transmitter. Transmit only mode. The ZaxNet transceiver will only transmit ZaxNet TC and audio and will NOT receive wireless TC or ZaxNet commands. This setting shuts off the ZaxNet receiver. Receive then Transmit mode. After boot up the ZaxNet transceiver will search for a ZaxNet signal for the selected time so it can receive and lock time code before it begins to transmit TC and confidence audio. This menu adjusts the state of the ZaxNet transceiver. This also sets how long after boot-up up the TRXLA3 will search for ZaxNet time code before it begins transmitting its audio over ZaxNet for monitoring purposes. This is so the TRX3LA can lock to ZaxNet time code source before the unit will send confidence audio over ZaxNet. 17 Zaxcom TRXLA3 ZaxNet Menu IFB Receive Pulse Set This menu will only appear if the TRXLA3 is set to go into transmit in the RX to TX Time menu ZAXNET RX PULSE:

OFF IFB RX PULSE 600 SECS The ZaxNet transceiver will stay in transmit mode and never go into receive mode. In this example the ZaxNet transceiver will go out of transmit mode every 10 minutes. This setting would be used so the TRX could update its time code while monitoring audio via an ERX receiver. This menu sets the interval that the ZaxNet transceiver will stop sending confidence audio and search for time code. When enabled the pulse setting tells the ZaxNet transceiver to leave ZaxNet transmit mode once every XXX seconds and go into receive mode so it can re-jam its time code wirelessly via ZaxNet. This setting would be used so the TRXLA3 could update its time code while monitoring audio via an ERX receiver. Please note when the ZaxNet transceiver searches for ZaxNet it will temporally go out of transmit mode for approximately 1 second as it searches for ZaxNet time code. The settings are NEVER or any interval between 5 and 999 seconds. Record Beep Set This menu will only appear if the TRXLA3 is set to transmit (TX) mode ZNET RECORD BEEP OFF When the record beep is set to ON, and the TRXLA3 is recording, the confidence audio sent to the ERX via ZaxNet will have an audible beep, in variable intervals, giving conformation that the TRXLA3 is indeed recording. The beeps will only be heard in the ERX and will not be recorded on the card, or be sent to the UHF receiver. The intervals can be set between 2 to 18 seconds in 2 second increments. 18 Zaxcom TRXLA3 Audio Menu AUDIO MENU High Pass Filter HIGH PASS FILTER:

90Hz The high pass filter is turned on and adjusted from this menu. The high pass filter range is 70Hz to 220Hz in 10Hz increments. 2K Notch Filter 2K NOTCH FILTER ON The 2K notch filter is useful in removing digital RF interference that can be introduced into some microphones. 19 Zaxcom TRXLA3 Audio Menu Dynamics DYNAMICS The dynamics is a soft knee compressor that is located after the analog to digital converter which will limit the dynamic range to prevent clipping during occurrences of loud audio. Dynamics is comprised of both a compressor and an expander, which operate jointly. The compressor in the dynamics can set to mild or extreme compression and features a soft knee for more transparent operation. To enter the Dynamics Menu Press the INC or DEC key - PARMS (parameters) will be displayed on the right. To move to the next parameter, press the MENU key. To exit this page, hold the MENU key for 1 second. Dynamics Parameters Link L-R: OFF / ON: If using a stereo LA3 transmitter this links the left and right signal so if one side of the signal needs compressing / expansion the other side will do the same to match. SPEED (Decay Speed) : SLOWEST / SLOW / NORMAL / FAST / FASTEST Sets how gradual the signal level decreases after a signal reaches the threshold setting. This is typically set to FAST. ATTACK (Attack Speed) : SLOWEST / SLOW / NORMAL / FAST / FASTEST Sets the speed in how fast the gain is reduced once the signal exceeds the threshold setting. This is typically set to FAST. CMP RATIO (Compressor Ratio): Valid range: 1.0: to 5.0:1, in 0.1 steps. The amount of gain reduction is determined by the compressor ratio setting. A compressor ratio for example of 2.0:1 means for every 1 dB above the compressor threshold the gain will be reduced 2dB. A higher ratio setting makes the compressor more aggressive. CMP THRESH (Compressor Threshold): Valid range: 0 to 96dB, in 1dB steps. This sets the level in which gain reduction occurs. CMP KNEE: (Compressor Soft Knee): Valid range: 0 to 20dB, In 1dB steps. Sets the compressor's soft knee. A soft knee reduces softens the audible change from uncompressed to compressed, this is useful especially for higher ratios where the changeover is more noticeable EXP RATIO (Expansion Ratio): Valid range: 1:1.00 to 1:4.00, In 0.01 steps Sets the expansion ratio. For example a 1:2.0 expansion ratio means for every 1 dB below the expansion threshold the gain will be reduced 2dB. EXP THRESH (Expansion Threshold): Valid range: 0 to 96dB, in 1dB steps. Sets the threshold above which gain reduction occurs. REDUCE (Expander Gain Reduction): Valid range: 0 to 36dB, in 1dB steps. This sets the limit on the amount of gain reduction caused by the expander. GAIN (Make-up Gain): Valid range: 0 to 30dB, In 1dB steps. Gain is used to compensate for the gain reduction caused by the compressor. Because the compressor is reducing the gain (or level) of the signal, the ability to add a fixed amount of make-up gain at the output is provided so that an optimum level can be reached. 20 Zaxcom TRXLA3 Setup Menu SETUP MENU Test Tone TEST TONE: ON I I I Battery Type Set The TRXLA3 has an internal tone generator which will generate tone so the signal chain can be properly gain staged. From this menu pressing the INC key will turn on the tone generator and cycle through the tone options which are 500Hz at -20dBFS, 1000Hz at -20dBFS or 500Hz at full scale. BATTERY TYPE:

ON This setting will hide the encryption menu. A hidden encryption menu allows for quicker navigation and prevents accidental changes. HIDDEN - The encryption menu doesnt appear when cycling through the menu settings. DISPLAYED - The encryption menu will appear. Encryption Code Set ID1: 000 ID2: 000 If an encryption code is set the transmitted audio will be encrypted and can only be listened to if the receiver has the matching encryption code entered. When receiving an audio signal and the codes do not match, all that will be heard is white-noise or silence. So if using encryption it is important to make sure the matching receiver has the same code. These two sets of numbers are formed into a single six-digit encryption code which provides a total of 16,777,216 possible combinations. Please note that both of these codes should be set to 000 for normal un-encrypted operations Adjusting the encryption code 1. Momentarily press the MENU key to advance to the next character. 2.

We also recommend only buying a brand name card such as Transcend, SanDisk. Please note Transcend Premium cards with the red stripe are not recommended. And very importantly please buy all cards from a reputable dealer because counterfeit cards exist and can cause recording issues. We also highly recommend that the all cards are tested before taking them out into the field. Here is a simple testing procedure to determine if the card will function correctly:

1. Format the card in the transmitter. 2. Power cycle the transmitter. 3. Record at least 20 minutes of audio to the card with no time code source. 4. Look at the Main Screen it should still be recording in segment #1. 5. Playback and listen to the file. Media Capacity The TRXLA3 can use Micro SD cards, up to 16 GB. While any size card will work we recommend using 4GB cards. All cards that are used in the TRXLA3 must be formatted in a 3 series transmitter to work properly, cards formatted in any other series transmitter will not record properly. Please note that regardless of the size of the card the onboard recorder will only be able to record up to 500 individual segments on any given card. Available recording times will depend on the selected modulation and are as follows:

Available Record Available Record Time Mono / Stereo SD Card Size 512 MB 1 GB 2 GB 4 GB 8 GB 16 GB 3 hours 6 hours 12 hours 24 hours 48 hours 96 hours Time XR / ZHD 6.75 hours 13.5 hours 27 hours 54 hours 108 hours 216 hours Please note the transmitter will NOT record onto the card if:

The card was not inserted before the TRX booted up. If the card was removed while the power was on. If LOW BATTERY is being displayed. Recording Format The media card is formatted using a FAT32 file system. While recording, the unit places all recorded audio in a single file on the media. The files generated by the recorder (.zax format) can only be recognized by Zaxcoms ZaxConvert program. Using ZaxConvert will transfer the file to a Broadcast Wave or MP3 file. ZaxConvert is available to anyone for free from the Zaxcom website http://www.zaxcom.com/firmware-updates 25 Zaxcom TRXLA3 Firmware Firmware Each unit is shipped with the latest firmware version installed. As newer firmware becomes available it can be downloaded from the Zaxcom website:

http://www.zaxcom.com/firmware-updates Newer version of beta firmware may be found on the Zaxcom Forums:

http://www.zaxcom.com/forum It is recommended to keep a copy of the SNXXXX.ME file for each transmitter. The SNXXXX.ME file contains the setup parameters of that specific transmitter - so in the event that there is a problem with the transmitter and the settings get corrupt the SNXXXX.ME file can be used to recreate the setting for that transmitter. To copy and save the SNXXXX.ME files simply format a card in each transmitter then copy and archive the SNXXXX.ME files to a computer. Updating the TRXLA3 firmware 1. Format a micro SD card in the transmitter. 2. Remove the card and with a computer delete the SNXXXX.ME file. 3. Download the TRX firmware THD-XXX.bin from the Zaxcom website and copy it onto the formatted card. 4. Power down the TRXLA3 and insert the card into the transmitter. 5. Simultaneously hold down the INC and DEC keys while powering up the unit. 6. The screen will display BURN ROM with the version of firmware that is loading. 7. From power up to DONE will take about 30 seconds. 8. Upon completion, cycle the power and confirm that the transmitter is running the new firmware. WARNING: Before updating the firmware be sure to insert a fresh set of batteries and do not power down the unit during the update process, if the unit should lose power during the upgrade, it may need to be sent back to Zaxcom for repair. Updating ERX firmware with a TRX transmitter 1. From the ZaxNet menu set ZaxNet mode to transmit (TX). 2. Check that the ERX is set to the same ZaxNet frequency that the TRX is set to transmit on. Check that the GROUP ID is set the same in both the TRX and ERX, and make sure encryption is shut off. 3. Format a micro SD card in TRX transmitter. 4. Remove the card, and with a computer delete the SNXXXX.ME file. 5. Download the ERX firmware ERX-XXX.bin from the Zaxcom website and copy it onto the formatted card. 6. Insert the card into the transmitter. 7. Proceed to the SETUP MENU and select PRESS UP TO SEND ERX PROG FILE 8. From the firmware update menu on the ERX press the INC key 5 times to see WAITING FOR PROGRAM. 9. Press the INC key on the transmitter to trigger the update process. 10. The ERX should indicate its progress after a few seconds. 11. When the ERX has been updated the screen will display SUCCESS. WARNING: Before updating the firmware be sure to insert a fresh set of batteries and do not power down the unit during the update process, if the unit should lose power during the upgrade, it may need to be sent back to Zaxcom for repair. 26 Zaxcom TRXLA3 Firmware Updating QRX firmware with a TRX transmitter 1. Format a micro SD card in a TRX transmitter. 2. With a computer take the formatted card and perform the following:

Delete the SNXXXX.ME file from the card. Download the new QRX firmware and load it into the card. (QR2-XXX.BIN) 3. Insert the card and a fresh set of batteries into the TRX transmitter. 4. At the QRX:

Verify the QRX is set to single mode and modulation is set to mono. Verify encryption is off (ID1 and ID0 are both set to 000) Set the UHF Frequency to the same frequency as the programming transmitter. The QRX receiver status LEDs should both be green. From the extended menu go to the firmware update page and press the INC key. The screen will display waiting for program. This indicates the receiver is ready to download the new firmware. This can be done to several QRXs so they will be updated at the same time. 5. At the transmitter proceed to the setup menu proceed to the firmware update menu (see TRX manual) and press the INC key. 6. Each QRX should indicate it is receiving the program. 7. After the firmware send cycle, all of the receivers should be re-programmed and SUCCESS . REBOOT NOW will be displayed. If there was a reception error, the affected receiver will automatically restart the process with the start of the next send cycle. 8. Reboot the QRX and verify the QRX is running the new firmware version. WARNING: After the QRX has received its entire program, it will erase and burn its firmware into the ROM. During this process, which only takes a few seconds, you MUST NOT turn OFF the QRX. If the program is never fully received, it is safe to cycle the power. 27 Zaxcom TRXLA3 Wiring Diagrams Inputting Audio The TRXLA3 use an unbalanced microphone input via a 3-pin micro-LEMO connector.
