Front Panel Menu Summary
Command Function Options/Response Format
Channel Format Sets the audio compression
format which determines how the
left and right channels of the
audio input source are
compressed.
? Stereo – left and right audio channels are
compressed separately into two output
waveforms. Stereo uses more bandwidth than
mono; however, if the input audio source is
stereo, the stereo effect will appear at the
output audio device.
? Dual Mono – the left and right audio channels
are compressed separately into two output
waveforms. This option uses more bandwidth
than mono, however, use this option when the
left and right audio channel inputs represent
separate and independent audio signals.
? Joint Stereo – the left and right audio channels
are compressed jointly into two output
waveforms. This option uses more bandwidth
than mono but less than the stereo and dual
mono options. Use this option when the left and
right audio channel inputs are highly correlated
(i.e., left and right stereo channels of one audio
program source). The SE4000 uses the
similarities between the two channels to save
bandwidth without losing the stereo effect at the
output audio device.
? Mono – during audio compression the SE4000
ignores the right audio channel input and
produces a single output waveform based on
the left channel input. This option saves
bandwidth; however, if the input audio source is
stereo, the stereo effect at the output audio
device will be lost.
