Matrix Surround

Audio Source

The Matrix Surround features the spacious sound effects of a stadium that can be turned ON or OFF.

Multi-Channel Television Sound will allow you to select STEREO (a stereo broadcast), MONO (monaural sound) used when receiving a weak stereo broadcast or 2nd Audio Prog (SAP) which may be a secondary language, weather report, etc. The sources received will be displayed at the top right edge of the TV. The source you select will be displayed above the sources received. See example below for each selection when both stereo and second audio are received (monaural is always received).

woofer output are OFF. Also, set to OFF, if you prefer to use only your head-phones.

Auto Noise Cancel This function eliminates the noise between stations. If a channel is tuned and is noisy, this function will automatically eliminate the audio for that channel.
