This option is used for RTS-configured beltpacks. You can use the High Cut
option with any system that has reduced frequency response and only noise
present in the audio band above 8 kHz or for headsets that sound too bright or
“tinny.”
M ONAURAL (M ONO ) AND B INARUAL O PERATION
By default, a dual-channel beltpack operates monaurally. The two audio channels
(A and B) are mixed equally into one signal that goes either to the one
headphone of a single-ear headset, or both headphones of dual-ear headset.
However, on the binaural beltpacks—RS-622, RS-623, and RS-623R—you can
select binaural operation when a beltpack has a binaural headset.
Note:Only the RS-622, RS-623, and RS-623R beltpacks offer the binaural headset
option.
Binaural operation routes audio from each of the two beltpack channels into a
separate ear of the binaural headphone: Channel A audio goes to the right ear of
the headphone and the Channel B audio goes to the left ear of the headphone.
You can also mix the audio channels that go to each earphone by sending a part
of the audio from a selected channel into the other channel.
Two slider buttons, shown in Figure 11, allow you to adjust the Channel A and
Channel B audio mix. The R-to-L slider affects the right earphone. The L-to-R
slider affects the left earphone.
Figure 11: Binaural Headset Mix Option
If you set a slider to the default position of None, the selected earphone (either
right or left) receives only one channel of audio. If you set the R-to-L slider to
None, the right earphone receives only Channel A audio. If you set the L-to-R
slider to None, the left earphone receives only Channel B audio.
If you set both sliders to None, the beltpack operates in complete binaural mode:
the right earphone receives Channel A audio and the left earphone receives
Channel B audio.
As you move the R-to-L slider up towards the All value, a percentage of the right
earphone’s audio (Channel A) mixes in with the left earphone’s audio (Channel
B). At midpoint on the scale, for example, fifty percent of the right earphone’s
audio mixes in with the left earphone’s audio.
