8910ADA-M/ST/SR — Instruction Manual

Module Configuration

When Local/Remote control is enabled (onboard jumper J4 is set to
LOC/REM as shown in

Figure 11 on page 24

), the Audio Status/Controls

web page shown in

Figure 17 on page 35

will be available.

Gain adjustment mode can be set in one of two Stereo/Dual modes:

Gain/Balance (

Figure 17 on page 35

), or

Independent Gain (

Figure 18 on page 36

).

Gain/Balance Mode

In Gain/Balance mode, the gain median point is set in the gain window
(from -20 to +30 dB). The balance window allows a balance adjustment of
plus or minus 6 dB for each channel with 12 dB total difference in gain
between the channels at ± 6 dB balance setting. Gain and balance adjust-
ments are in 0.1 dB increments.

Note

Non-zero balance value entries will preclude full range of Gain adjustment.

Note

Gain value entries within 6 dB of -20 dB or +30 dB will preclude full range of
balance adjustment.

A negative value entered in the balance window raises Input 1 level by the
gain in the balance window and lowers Input 2 level by the same amount.
A positive entry does the opposite.

Table 5

provides the mid-point and

maximum balance adjustments possible using the 3.5 gain setting shown in

Figure 17 on page 35

.
