site X will get the audio from audio input A and site Y will get the audio
input into audio input B.

Finally, the mode can be used to transmit two channels between two units.
Both "lines" must be dialed up – Line 1 to Line 1, Line 2 to Line 2. It is
important to understand the difference between this use of L3 Dual/Mono
and the L3 Stereo and L3 J ‐ Stereo modes.
a) L3 Dual/Mono keeps the two audio channels completely separate.
In fact, it does not ensure that the two channels remain phase ‐
aligned.
b) L3 Stereo keeps the two channels separate (i.e. there is no danger
of cross ‐ talk) and maintains phase ‐ alignment between the two
channels. However, the perceptual model used with L3 Stereo does
assume that the listener will be hearing both channels
simultaneously (i.e. that this is a stereo application). Therefore, the
model takes into account that audio from one channel may mask
audio from the other channel.
c) L3 J ‐ stereo matrixes the two channels together and therefore a
small amount of inter ‐ channel interaction is possible.
L3 Dual offers 15 kHz audio frequency response when the Sample Rate is set to
32 kHz, or 16 kHz audio frequency response if the Sample Rate is set to 48 kHz.

ZEPHYR CLASSIC VS XSTREAM COMPARISON!
Early Layer-3 Zephyr’s call this mode "Mono/Dual". Later 3 Zephyrs call this mode
"L3 Dual".

HOT TIP!
These different uses of the L3 Dual/Mono mode may require different receive modes
depending on the use and the far end codec.
