ÃStereo and Dual Mono selection — To select stereo or dual mono audio output, set the switch to the desired position. Dual mono sums left and right audio signals together and outputs the same signals on both audio output channels. Default setting is mono.

NFor best results when speech is the primary audio, set this switch for dual mono with the high pass filter set to on. If music is involved, set the switch to stereo with the high pass filter set to off.
