MONO 3CH, Option A Mono primary, two references on LREF and RREF.
MONO 3CH, Option B Mono primary, two references on RIGHT and LREF.
MONO 4CH Mono primary, three references on RIGHT, LREF, and RREF.

Table 1: Filter Input Configurations
As you press the MONO/STEREO and nCH selection buttons, the LEDs next to
each input gain dial will indicate the use of each channel. Cycle through the
modes until you reach the one you want. Note that only the legal nCH modes
are shown based on the MONO/STEREO section. For instance, you cannot
select 4CH if STEREO is selected, because STEREO 4CH is not a valid mode.
The LEDs light green for primary channels and red for reference channels. For
instance, in the MONO 2CH Option A mode, the LEFT channel LED is green and
the LREF LED is red. In the STEREO 3CH mode, the LEFT and RIGHT channel
LEDs are green and the LREF and RREF LEDs are red.
3.1.4.2 Bandwidth Control
Use the BW selection to choose the bandwidth at which audio will be processed.
The 5 kHz bandwidth uses a sample rate of 9.8 kHz, the 10 kHz bandwidth uses
a sample rate of 22.05 kHz, and the 20 kHz bandwidth uses a sample rate of
44.1 kHz.
Regardless of the sample rate at which audio is processed, the TOSLINK output
always uses a 44.1 kHz sample rate.
3.1.4.3 Highpass Filter
Use the HPF button to turn the highpass filter on and off. When the button is in,
the HPF is applied.
3.1.4.4 Automatic Gain Control
Use the AGC button to turn the automatic gain control on and off. When the
button is in, the AGC is applied.
