User manual SIMA UDC-3X

[. . . ] The unit supports stereo audio as well as both composite and S-Video. · 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. [. . . ] 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. Option B: If your TV has 2 video inputs that supports both composite video and S-Video inputs, you can feed both the composite and S-Video outputs from the UDC-3X to your TV. You will have to select the correct video input on your TV, composite or S-Video. This will give you the best picture quality. Note that this only works if the composite video and S-Video inputs are two separate inputs on your TV. Otherwise the picture may be blank, black and white or have lines and steaks. 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. Although the UDC-3X will not eliminate all of these volume fluctuations with these types of commercials, it will help a great deal to keep the volume level constant. Caution: Very loud sound levels can result when using the 1:2 expansion mode. [. . . ] Stand-by light is dim (normal in stand-by mode) Is power light on?Make sure inputs and outputs are not reversed.
