Reduce the RF output using an attenuator. (ChannelPlus coax panels are designed to take the full output Video/audio out of these modulators.) Video/audio out Audio volume seems low compared to broadcast … There may be little you can do here, other than turn up the volume. Here is what is happening: VCR 12:00 DVD ! In broadcast television, the audio is compressed: The soft sounds are amplified VCR to be almost as loud as the loud sounds. The technical measure of this is RG6 coax dynamic range, the ratio of loudest to softest sounds. The dynamic range of video devices such as DVD and LV players is very great. Since most of a typical movie consists of ‘soft’ sounds, the audio will seem quieter than normal television channels. (This is also why commercials, which are the most compressed, seem louder than the program they accompany.) ! To appear to be at the same volume as broadcast channels, the audio level in a modulator is carefully increased. In the modulator, too high of signal level can overdrive the MTS circuits and audio performance will suffer. No Stereo … When using the TV outputs to send audio to a home theater system, be sure the TV is in the stereo mode for external speakers.
