Configuration

The 8920ADT can be configured locally using onboard switches and
jumpers or remotely using the 8900NET Network Interface module with
version 2.1 or later software.

The following parameters must be set on the 8920ADT module:

Input level (Left and Right) — gain adjustment of analog input levels
for full-scale digital outputs (0 dBFS),

Delay — amount of delay applied to digital output signal,

Output mode — channel swapping, summing, tone and phase inver-
sion,

Output audio bit resolution — selection of 20-bit or 24-bit output,

Balanced or unbalanced outputs, and

Control mode — Local/remote or local control only (remote lockout).

Local Onboard Module Configuration

The 8920ADT module can be configured locally using the jumpers, rotary
switches and the paddle switch shown in

Figure 5 on page 10

. The CONF

LED indicates status of the configuration process.

These components perform the following:

SW 1 Control (rotary) switch selects functions performed by paddle
switch SW 3. Refer to

Table 6

for details.

SW 2 Mode (rotary) switch selects a desired output configuration (0
through 9, A through F), although not all positions are used. Refer to

Table 7 on page 12

for details.

SW 3 (paddle) switch executes the functions selected by the Control
rotary switch. Refer to

Table 6

for details.

Jumper JP4 sets control mode for Local only or Remote and Local.

Jumper JP6 sets the output bit resolution (20- or 24-bit).

Jumpers JP7 and JP8 determine whether AES outputs are balanced or
unbalanced.

CONF (configuring) LED – when on, indicates the module is initial-
izing or processing configuration information.
