User manual SIMA UDC-3X

[. . . ] · Dual A/V outputs to connect to your TV, your surround sound receiver and/or a recording VCR. · Composite video to S-Video conversion to simplify hook-up in systems using both composite and S-Video. · Automatic Input Mode (AIM) provides automatic switching to active input without you having to push any buttons. Simply turn on your VCR and the UDC-3X connects it automatically to the TV. [. . . ] Figure 4, Overview of typical system Step 1 Connect the AC adapter to 120 VAC and plug the DC cord into the 15 v input on the UDC-3X. If you want to watch and listen to the video sources on your TV and / or your surround sound receiver, see figure 5. If you want to be able to watch the video sources on your TV, listen on your surround sound receiver and tape from the sources plugged into the UDC-3X, see figure 6. This shows how to connect one of the outputs of the UDC-3X to the Audio and Video inputs on the VCR that you will use for recording. Note: Do not select the same input that the recording VCR is connected to (input 4 in this diagram) while recording or loud feedback could occur. If you only have composite video signals or only S-Video signals, then use the one type in your system. If your TV only has composite video inputs, you must use all composite video signals into the UDC-3X as it will not convert S-Video signals to composite video. If you have a combination of standard composite video (RCA type jacks) and S-Video (mini-din jacks) on your equipment you can only feed one or the other but not both to any given input to the UDC-3X. Page 6 In this case you have several options. Option A: For ease of use, the UDC-3X has a composite to S-Video converter . You can feed a combination of composite and S-Video to the UDC-3X and feed only a S-Video signal to your TV. This lets you use just one S-Video input on your TV and all sources will automatically be displayed there. When the unit detects an active video input (composite or S-Video), the Power / Standby light will turn on full and the active input will be selected. Power As long as AC power is not lost, the previous status (last selected input, Volume Stabilizer mode and AIM status) will be resumed when Power / Stand-by is pushed. If AC power was lost, the unit will default with input #1 selected, Volume Stabilization on and AIM on. Inputs Pushing an input button on either the front panel or on the IR remote, will cause the current input and associated LED to go off and the new input to come on. If the Auto Input Mode is on, the selected input will over ride the current input until another input is selected or another input is automatically detected. Auto Input Mode If the Auto Input Mode (AIM) is active, the unit will look for a video signal on the video inputs to select an input. If a second input becomes active, the UDC-3X will automatically change to the new input. If you want to go to another A/V source, simply select the input using the front panel button or the remote. If you don't want the UDC-3X to automatically select an active input, turn the AIM mode off. Please note when you activate AIM, it scans the inputs when the UDC-3X is on or in the stand-by mode. When the unit is in the standby mode, the Power/Standby light will be dim and all other lights will be off When a video device is turned on, like a VCR on Input #1, the Power/Standby light will become bright, the input corresponding to the device will turn on. Note: It is normal to notice volume variations even with the UDC-3X set to the 10:1 setting. This is due to the fact the human ear is more sensitive to certain frequencies and these will tend to sound louder. Some commercials on TV have been modified to sound louder than the normal program. [. . . ] This way, the unit automatically brings up soft dialogue when watching movies. The diagram below shows the relationship between an input audio signal and the output audio signal. Normal output level for most consumer equipment is about -10 dbv (aprox. This is why all Page 12 the curves intersect at the -10 dbv point. [. . . ]
