1 General
The DA-AA is a dual 4 output analogue Audio Distributor. The DA-AA can be configured as
either a dual 1x4 or a single 1x8 amplifier. The latter configuration is made by connecting the
inputs in parallel or using DIP switch on PCB. The Distribution amplifier has differential inputs
and differential outputs. Overall gain can be set by DIP switches or by potentiometer for high
precision gain setting. The gain range setting is from -12 to +12 dB. The input signal can be
mixed to the other channel using a DIP switch. The Distribution Amplifier handles analogue
audio signals from 20Hz to 80 kHz. The DA-AA is designed for all audio distribution purposes
in studio, duplication and Broadcast applications.

4 Output configuration
There are two groups of four outputs, ANA1 and ANA2 output. The two groups are
individually configured using DIP switch 3 and DIP switch 4. The switch sets which of the
input that is connected to the output.
4.1 Configuration of ANA1 output
Use dip switch SW4 / ANA1 for setting the outputs ANA1.

5 Connector module
Figure 8 - Overview of the ADC-AES-C1 connector module
The DA-AA has a dedicated connector module: ADC-AES-C1. This module is mounted at the
rear of the sub-rack. The module is shown in figure 6. J4 is the input DSUB connector, while
J6 is the output connector. Both connectors are FEMALE.

6 Module status
The status of the module can be monitored in three ways.
1. GYDA System Controller (optional).
2. LEDs at the front of the sub-rack.
LEDs are mounted on the module itself, whereas the GYDA System Controller is a separate
module giving detailed information on the card status. The functions of the LEDs are
described in sections 5.1. The GYDA controller is described in a separate user manual
6.1 Front panel – status monitoring
The status of the module can be easily monitored visually by the LED’s at the front of the
module. The LED’s are visible through the front panel. The LED on top tells if the DA-AA is
ok or not (green LED means ok – red is alarm). The second LED gives the input signal
status.
The DA-AA has 2 LEDs each showing a status corresponding.

All commands follow the Flashlink protocol and can be used for direct control access to the
module. The control system can either be a GYDA-SC or a third-party control system with
integrated Flashlink protocol. The module can also be manually controlled with a VT100
compatible terminal program.
The protocol can be found on our web page: http://www.nevion.com
