Installation
Caution
The CardModule is shipped in a
protective anti-static bag. Please take
suitable precautions to avoid static
discharge onto any part of the PCB or
components when handling module or
serious damage could result.
Each Card Module is supplied with a rear
connection panel and two mounting screws.
Please follow the following procedure for
installation of the card module into the Series 5000
Card Frame.
a) Select a slot in the card frame where the
CardModule will be located
b) Remove the blank connection panel from the
rear of the rack (if fitted)
c) Install the rear connection panel using the
screws supplied. Do not tighten the screws fully
d) Slide the card module into the card frame and
carefully check the CardModule easily
connects to the rear connection plate. The
card should fit easily and should not require
excessive force to insert, if you feel any
resistance, there could be something wrong
with the rear connection panel location. Do not
try and force the connection. Remove the rear
connection panel and check alignment with
the CardModule.
e) Insert and remove the CardModule a few times
to ensure correct alignment and then tighten
the two screws to secure the rear connection
plate

Settings and Control
The D AA 5320 has an integrated micro-controller,
which enables the module to be configured and
controlled locally via the dip-switch and the up-
down push button, or from remote when using one
of the optional controllers and control software.
Once set, all settings are automatically saved in
non-volatile internal memory. (Flash ram) The
module will always recall the settings used prior to
power down.
The module local configuration and gain settings
are performed using a 4-position dip-switch and
up/down adjustment switch on the front edge of
the module. These controls are used to preset
stereo or mono operation and set the required gain
parameters within the module.
Please refer to figure 2 for the location of these
adjustments and use the procedures defined in the
next section to configure the D AA 5320 module.

Reference Manual D AA 5320 Version 2.0
Page 17
Switch Settings
Below the switch settings for the 4-position dip-
switch are defined. Please refer to figure 2 for the
location of the switch. There is also a rocker style
switch on the module edge for Up / Down. This
switch is used for gain adjustments.
Note. The module dip-switch is not a usual implicit
selection switch used to define simple functionality.
Setting the module is an interactive process, which
involves setting the switch state to enable the
setting or adjustment of a certain parameter, and
then storing settings in flash memory. Please read
this section fully and review the procedures before
attempting any changes to the module settings.
Factory Preset Condition
The D AA 5320 is delivered with stored presets for
the following functionality.
Mode: Stereo
Adjustment: Gang Mode
Gain Setting: Unity OFF(0dB both channels)
Gain: Channel: Left
No further adjustments are needed if this is the
functionality desired.

1 OFF Disable Local Adjustment

2 OFF Mono mode 1 x 1:8
ON Unity ON
3 OFF Unity OFF
ON Select RIGHT input channel
4 OFF Select LEFT input channel

Reference Manual D AA 5320 Version 2.0
Page 18
Adjustment Procedures
The modules configuration and gain settings are set
using combinations of the dip-switch and the Up /
Down switch on the module edge.
Setting functionality and calibration is interactive
and not an implicit switch setting process. The
adjustments are made through imbedded micro-
controller and settings stored on internal flash ram.
To simplify the configuration and setting of the
module a series of procedures has been defined to
make setting the module easier. These are:
•Set Stereo / Mono Mode
•Set Unity Gain (using gang mode)
•Set Unity Gain (Individual channels)
•Set Stereo Gain Levels (Using gang mode)
•Set Stereo Gain Levels (Individually)
•Set Mono Gain Level
These procedures capture most things you would
need to change or set on the module.

Set Stereo / Mono Mode
The D AA 5320 module can be set to one of two
preset modes of operation.
Stereo. This is a simple 2 x 1 to 4 amplifier.
Independent left and right channels passed
through the amplifier providing four balanced line
outputs for each input channel.
Mono. This is a simple 1 x 1 to 8 amplifier. The signal
on the LEFT input channel is passed through the
amplifier providing eight balanced line outputs of
this channel.
Use this procedure to select Stereo or Mono modes
of operation.
1. Set Switch 1 [enable local adjustment] to ON
2. Set Switch 2 [stereo / mono select] to ON for Stereo
or OFF for Mono*
3. If 10 seconds pass with no further adjustments
being made both channel status LEDS will flash
yellow four times. This confirms settings have
been written into flash ram and stored.
4. To prevent further accidental adjustment it is
recommended to set Switch 1 [enable local
adjustment] to OFF
* When in mono mode the RIGHT channel indicator will go out.

Set Unity Gain (using gang mode)
Setting unity gain with gang mode enabled allows
the retention of any relative gain offset that may
have been set previously between the channels.
Setting unity will take the higher of the two
channels to unity (0dB) the other channel will retain
its relative negative offset.
1. Set Switch 1 [enable local adjustment] to ON
2. Set Switch 2 [Stereo / Mono Select] to ON
3. Set Switch 3 [Set Unity] to ON
4. Select Gang Mode: * Toggle Switch 4 [channel
Select] twice within 2 seconds. (Both channel
LEDs will flash yellow once at the same time)
5. Push either the UP or DN push button once, this
will set the higher of the two channels to unity
gain (0dB) The other channel will retain its
previously stored relative offset (if any)
5. If 10 seconds pass with no further adjustments
being made both channel status LEDS will flash
yellow four times. This confirms settings have
been written into flash ram and stored.
6. To prevent further accidental adjustment it is
recommended to set Switch 1 [enable local
adjustment] to OFF.
* Gang mode of operation simply couples the two channels
together for adjustment purposes. If there was a previously
stored gain offset between left and right channels, gang mode
will keep the offset and perform a uniform adjustment to both
channels preserving the previously stored offset.
To disable gang mode change the state of Switch 4 [channel
select] once. The channels can now be adjusted on an
individual basis.
