TUDQVPLWWLQJSRZHUG%P Battery required( not included):2x AA alkaline batteries OPERATION 1. Remove the battery cover and insert 2xAA alkaline batteries. Make sure that batteries are correctly installed. Then replace the cover. Please replace with new batteries immediately when batteries are low. 2.Insert the antenna into the antenna port and rotate the end until it clicks into place. Then rotate the pole to a vertical position. Then plug the AC adapter into the DC power input on the rear panel of the receiver. Connect the AC adapter to AC100-240V 50-60Hz outlet. Then connect the microphone system to the powered mixer equipment through the XLR outputs or the mix output. RF IR RF IR RF IR RF IR 3.Turn on the receiver and the microphone. Check if the microphone and the receiver have the same frequency. If not, refer to FREQUENCY SETTING section and sync the microphone and receiver. If you use multiple sets together and want to change the frequency, please set each receiver channel to different frequency first. Then turn on one microphone and sync. After it is synced, turn on another microphone and repeat until all microphones are synced. 2 WWW.PRORECK.COM SUPPORT@PRORECK.COM WWW.PRORECK.COM SUPPORT@PRORECK.COM 7 FREQUENCY SETTING
(1) Manual frequency setting RF IR 6 RF IR RF IR RF IR The microphone system has four channels and please adjust the frequency and sync one by one. 1.Press button or button to find a desired frequency for channel 1. When the frequency number is flashing, press SET button to lock the frequency. 2.Turn on one transmitter, face the IR sensor on the transmitter directly to the IR indicator on channel 1 and then press SET button. The IR indicator flashes and transmitter and receiver begin to sync. 3.Check if there is RF signal on the LCD screen. If not, repeat step 2. 4.Turn off the transmitter and repeat the above steps for channel 2,3 and 4. Note: Frequency will not be changed if you fail to lock the frequency when the frequency number is flashing. Besides, the receiver will exit the syncing mode if the transmitter is not paired with the receiver when IR indicator is flashing.
(2) Automatic frequency setting RF IR 6 RF IR RF IR RF IR The microphone system has four channels and please adjust the frequency and sync one by one. 1.Long press button and SET button or long press button and SET button simultaneously for channel 1. Then system will scan and choose an available frequency which is free of interference. 2.Turn on one transmitter, face the IR sensor on the transmitter directly to the IR indicator on channel 1 and then press SET button. The IR indicator flashes and transmitter and receiver begin to sync. 3.Check if there is RF signal on the LCD screen. If not, repeat step 2. 4.Turn off the transmitter and repeat the above steps for channel 2,3 and 4. Note: Frequency will not be changed if you fail to lock the frequency when the frequency number is flashing. Besides, the receiver will exit the syncing mode if the transmitter is not paired with the receiver when IR indicator is flashing. IMPOTANT: Be sure that only turn on one transmitter at a time when synchronizing. FEATURES
(1) Wide-band UHF Digital Transmition The system features 200 selectable frequencies, which reduces interference and allows you to use up to 20 sets at a time.
(2)Micro Computer CPU Control The system is controlled by micro computer and has higher stability than the traditional. It adjusts or auto-searches the frequency intelligently with less error and more accuracy.
(3)Clear LCD Display All operations can be displayed on the LCD screen for easy and visible control. You can see the frequency, channel, battery level of the transmitter, RF signal strength, audio signal strength.
(4)Infrared Data Transmition and Digital Sync Technology IR transmition function has less interference and ensures clear frequencies. Besides, the receiver syncs with the transmitter automatically when the LCD screen of the transmitter is faced to the receiver LCD.
(4)Automatic Frequency Search & Manual Frequency Selection There are two ways to adjust the frequency:Automatic frequency search & Manual frequency selection. Automatic frequency search is easy and convenient to use, while manual selection allows you to set the frequency according to your needs. RECEIVER OVERVIEW Front panel 27 28
