If power adapter is connected, red LED signal appears at the front display panel. If not, it is either input power is turned off, or system has error. ll Power LED is glooming red, but the system doesnt wake up, at all. If you use remote control, make sure that the direction is placed properly and battery is charged. Also, check power switch at the front panel. If all the above are normal, you may suspect that the problem can be caused by system error ll When power is turned on, there are several flickering at the front panel and it does not proceed to normal procedure. It may be caused by system error. In this case, you have to only operate remote control and Power On/Off button. 2 There is no sound from my system. ll First check that audio signal routes into the selected input. Normally LED is on to show PCM (In this case, front panel displays the current input mode, d.OP, d.CO or A.In). If Dolby Digital signal routes properly, front panel LED will display Dolby Digital format like 3.2.L, 2.0, and Digital LED will be turned on. ll See if Mute button is pressed. ll Check if you reduced the master volume beyond the audible limit. The range of master volume is from 74 dB to +6 dB. Sound level increases when approaching from to + section. ll Check the connected power amplifier and speaker system. Check SDC-800T output, power amplifier or speaker inputs are connected properly. Check the connection of power amplifier to power supply, or volume level is properly set. ll Press the Test Tone button to check if you can hear the test signal from the speakers installed. 3 How can I play DVD-video using my computer?

ll If you want to enjoy DVD in your computer, you should be equipped with the followings. DVD ROM Drive S/W DVD Player supporting digital S/PDIF output N Recently released most S/W DVD Players support digital output using various sound cards. NN oo tt ee : Be aware that depending on the revision number, some S/W DVD Player doesnt provide digital output. Make sure that S/PDIF Output or Dolby Digital 5.1 Channel is configured separately in the property and/or setting. N PC sound card which S/W DVD Player supports S/PDIF output. Recently released sound cards from Creative, Yamaha , CMI, etc are supported by major S/W DVD Players. For further information, please refer to the instruction manual of the sound cards. H/W MPEG2 Decoder board. N Most H/W MPEG2 board has digital AC-3 pass-through output terminal. You can connect it to the digital input of SDC-800T. VGA video card having sufficient capacity of graphic processing. 27 SDC_800T 5/22/01 5:28 PM Page 28 ll If the above requirements are satisfied, there will not be any difficulties in playing DVD movie even with Pentium-II class computers. Because the 5.1 channel audio signal is transmitted via digital output, SDC-

800T input must be configured for digital input, not analog. If you have S/W DVD Player, you have to select S/PDIF output or Dolby Digital 5.1 Channel. If not, you may hear the Down-Mixed Dolby signal in a regular PCM stereo format. NN oo tt ee : Refer to chapter 8. Glossary, Down-Mix 4. I can play and watch DVD without any difficulty. But, how can I make sure that SDC-800T reproduces Dolby Digital/DTS signal?

ll If the SDC-800T reproduces this Dolby Digital signal, 3.2.L, 2.0 character will appears at the front panel, and you can hear sound from several speakers. Even though the display of 3.2.L, 2.0 does not appear at the front panel, and you can still hear the movie sound; then its either. N Input was connected to analog and you are hearing the stereo sound. N Or, input is connected to digital, but you are hearing the down-mixed digital PCM into digital input. Make sure that S/PDIF Output or Dolby Digital 5.1 Channel is configured properly in the property and/or setting of S/W DVD Player. Even though 5.1-channel Dolby Digital signal appears, I can only hear the sound only from the L/R speaker. ll If 3.2.L appears at the front panel and you can only hear sound from L/R speaker, then check if SURROUND mode is changed to Stereo mode. If so, press the SURROUND button to change to Dolby mode. 4 5 ll Listen carefully whether the music is recorded in the way that big sound can be heard only from L/R speaker. ll Check that speaker connection, power amplifier, speaker power supply, or volume level is in a normal status. 6 Whats the support for high quality PCM audio with SDC-800T?

ll SDC-800T automatically detects and supports high sampling rate (88.2kHz and 96kHz) PCM audio. No user intervention for SDC-800T is required, at all. When SDC-800T detects these PCM stream, then front panel display will show sampling rate characters, like F.88 (for 88.2kHz), F.96 (for 96kHz. ll You have to make sure that your DVD player or other source equipment can delivers these digital audio data via S/PDIF channel. Some DVDP provides separate Setup Menu option for enabling this feature. In some cases, DVDP will deliver the down-sampled PCM data (96kHz 48kHz, 88.2kHz streams. Therefore, please check with your DVDP operational manual for detailed information 44.1kHz), while others will not be able to handle these 7 What should I have to do to listen to MP3 with my computer?

ll MP3 music we listen with our personal computer is the converted PCM after CPU has decoded. You can, therefore, listen and enjoy MP3 music through SDC-800T digital or analog input. ll In case of digital input, some sound cards are supposed to set digital output to On/Off in accordance with some types of music resources. If you have some special inaudible sounds (eg. In case that you can hear Midi or wave, but cant CD Audio), you may have to enable it considering the settings above. It is common to adjust using s/w like control panel or sound card application for Windows. Please refer to the instruction on sound card. 28 SDC_800T 5/22/01 5:29 PM Page 29 8 9 10 11 May I connect audio output of regular TV or VTR to SDC-800T?

12 May I connect audio output of regular MP3 Player to SDC-800T?

Can I connect audio output of regular home Music Box, or CD Player to the SDC-800T?

ll You can surely listen to the music by connecting analog or digital output to SDC-

800T and also include proper sound effect modes. ll In case of analog output, you connect line output. If there is no line output available in the TV/audio equipments, you may use headphone output. But, in case of regular speaker terminal only, dont connect them to SDC-800T, because there is great difference in signal level, and it may damage the SDC-800T. ll Analog input of SDC-800T is mini-stereo phone type, so it is generally inconsistent with RCA output mostly applied with regular TV or VTR. You may buy the cable terminal converter and solve this problem easily. ll Audio output of old-dated TV or VTR could be mono type. In this case, it is difficult to get the best effect as you want, even if you manage to input the mono signal into SDC-800T after adjusting terminal Can I connect audio output of regular DVD Player or LD Player to SDC-800T?

ll Its the same as above. You can listen and enjoy sound by connecting analog or digital output to SDC-800T and also include proper sound effect modes. Some devices may transmit Dolby 5.1-channel in digital output, and SDC-800T has a capability of dealing with it properly. ll In case of analog output, SDC-800T analog input is for mini-stereo phone type and it is inconsistent with RCA output mostly applied with regular DVDP or LDP. You can buy the cable terminal converter and solve this problem easily. How can I check that Optical digital input is being processed properly. ll First check that the device transmits optical digital output signal properly. You can see that the end of optical cable turns red when the digital signal is transmitted. But, even though the one end of optical cable turns red, it is difficult to convince that all the digital signal is being transmitted properly. First of all, connect the cable to the optical digital input of SDC-800T, select the input as Digital Optical, and then check the front panel and LED In most cases, PCM LED will appear (in this case, current input mode will be displayed like d.OP) If Dolby Digital signal received, Dolby Digital format will appear on the panel display, something like 3.2.L, 2.0, etc) 13 I would hear noise from speakers ll SDC-800T is an advanced high-tech audio device with quality proven by Dolby Laboratories, and is prepared to some degree of power fluctuation. But this kind of problem can be caused if the condition of power supply is very poor. ll If then, you may have to use special AC-to-DC adapter in the area where the power voltage is below 10% for AC input standard power level of 220V.

(available in case of Free Voltage AC input, output power DC 12V, over 1 A ) 29 SDC_800T 5/22/01 5:29 PM Page 30 Glossary 1 2 3 What is Dolby Digital?

ll Dolby Digital, developed by Dolby Laboratories is a multi-channel standard for digital audio. Increasingly it is applied to general music genre as well as movie theaters and DVD title. Multi-channel represents an audio system equipped for more than three speakers. Generally Dolby Digital supports six-speaker output (L/R/C/RL/RR/SW). Currently there is an extension to Dolby digital supporting up to seven output

(L/R/C/RL/RR/SW/Rear Center). What is DTS (Digital Theater System)?

ll DTS (Digital Theater System) is another form of advanced multi-channel sound, supporting 5.1-channel or 6.1-channel surround system. In many countries, more DVD titles in compliance with DTS and Dolby Digital have been released and will be released, more. What is Dolby Pro Logic?

ll Dolby Pro Logic is a standard for 4-channel output(L/R/C/S) developed by Dolby Laboratories using stereotype 2-channel signal before the invention of Dolby Digital. Dolby Pro Logic has been applied to home audio, VTR, as well as movie theater . There are Dolby Digital signals, which has been encoded into Pro Logic mode. If SDC-800T reproduces this signal, 2.0.P string and will appear on the front display panel at the same time. It means that stereo L/R signal includes extra 2-channel signals for center and rear. Digital LED 4 5 6 7 What is Dolby 5.1-channel?

ll Among the six speaker channels, sub-woofer can only reproduce low frequency of narrow bandwidth (20Hz ~ 120Hz). Compared with bandwidth

(20Hz~20kHz) frequency of other channels, it shows 0.1 and it is called as 5.1-channel audio. Dolby extension which supports 7speakers, is referred to as 6.1-

channel. What is high quality, high sampling rate PCM?

ll With the advent of digital technology, request for high quality audio has resulted in high data rate (higher than 96kHz), high quality (more than 24bit ADC) PCM audio, which is almost 3 times the data rate to normal CD audio

(44.1kHz, 16bit ADC), and with better sound quality. SDC-800T automatically detects and supports these high quality PCM streams, boasting support for sampling rate up to 88.2kHz, 96kHz, and ADC resolution of 24bit. What is Dynamic Range?

ll Dynamic Range indicates the value that converts into dB unit the difference between the highest-level and the lowest-level sound in an amplifier. What is Dynamic Range Compression?

ll Dynamic Range Compression is a sound filtering technology, which intentionally narrows the sound difference by reducing high-level signal whereas expanding low-level signal in Dolby Digital Decoder. This technology enables us to listen both low and loud sound even at low volume. 30 SDC_800T 5/22/01 5:29 PM Page 31 8 9 10 Setting values in SDC-800T audio function can be changed into No (0%, default), Half (50%), or Full (100%). Midnight Mode from other vendors home Dolby decoder is equivalent to SDC-800T Full (100%) setting. What is Surround Delay?

ll Surround Delay makes signals route delayed from Dolby Digital or Dolby Pro Logic to surround speaker. It is used to feel as if you listen in a large room or to avoid the change due to location limits of a speaker . Setting values in SDC-800T can be changed from 0 ms (default) to 15 ms. What is Center Delay ?

ll Center Delay makes signals route delayed from Dolby Digital or Dolby Pro Logic or DTS to center speaker. It is used to feel as if we listened in a large room or to avoid the change due to location limits of a speaker. Setting values in SDC-800T can be changed from 0 ms (default) to 5 ms. What is Bass Management?

ll Bass Management is the technology that Dolby Digital sends low bandwidth frequency (20Hz ~ 120Hz) supposed to be transmitted to subwoofer toward Surround L/R large speaker, or sends low bandwidth frequency of other 5-channel toward subwoofer. Bass Management has Mode 0,1,2,3. SDC-800T automatically supports mode 1 and 2 depending on the size and existence of speakers. 11 12 What is Surround Mode, Surround Effect?

ll Because PCM or analogue 2-channel-audio uses the signal for surround L/R speaker it cannot take advantage of multi-channel audio. If decoder provides special surround mode, C, RL, RR, SW channels can also provide converted signal and users have surround effect of multi-channel with 2-channel input. SDC-800T provides modes of Music, Theater, Stadium as well as Dolby, DTS modes, and you can listen to music, play games, or enjoy movie with these modes. What is Down-Mix?

ll Down-Mix is feature when multi-channel input signals such as Dolby Digital, Dolby Pro Logic and DTS are decoded and the number of output channel is smallerthan the number of input channel (eg. 4-channel signal goes toward 2-channel speaker), reduce the number of channel by distributing output to the existing speakers. SDC-800T automatically provides Down-Mix mode conforming to the speaker connection and input mode. 31 SDC_800T 5/22/01 5:29 PM Page 32 M e m o 32 SDC_800T 5/22/01 5:29 PM Page 33 33 SDC_800T 5/22/01 5:29 PM Page 34 34 SDC_800T 5/22/01 5:29 PM Page 35 35 COVER_OUTPUT. 5/22/01 5:33 PM Page 2 Seodu, SDC-800T
