ADDA-AES8 Rev. B

1 Product overview

The ADDA-AES8 is an audio converter product with both A/D and D/A converters on a single
module. The module may be used as a normal Flashlink module in the original frame, in N
boxes and Flashcase. The module may also be used in the new frame in the half width slots
as an auxiliary module for the Flashlink XMUX embedder modules.

The module has two stereo A/D converters and two stereo D/A converters. The gain of the
converters may be set on the DIP switches on the module or with the GYDA Multicon system
controller. The gain settings on the A/D converters are discrete levels while the D/A
converters may be set to a level from +24dBu with 1 dB steps.

The converters are calibrated with low impedance sources and high impedance terminations.
The inputs and outputs are fully compatible with 600 ohm inputs and outputs. True 600 ohm
outputs and inputs are available through special backplanes but the D/A output levels set
with the DIP switches and viewed through GYDA will be 6 dB too low.

The A/D converters may be synchronized to an external AES3 signal with a sample
frequency from 24 kHz to 96 kHz.

The A/D converters’ internal clock, used when there is no reference input, may be configured

to be 48 kHz or 96 kHz.
The D/A converters will accept sample rates up to 192 kHz.

3 Configuration

The module has two main configurable parameters.

1. Converter gain

2. A/D Internal clock frequency 48 or 96 kHz.

As all Flashlink modules, the module either uses the internally stored configuration, or uses

the configuration on the DIP switches. The DIP switch labeled ‘DIP config mode’ controls this

behavior.

3.1 DIP configuration mode

SW2.8 is the DIP config mode switch.
On: The card will be configured with the other DIP switches. The module will not accept

commands from the system controller but may be monitored.
Off: The module will be configured with the internally stored configuration and may be

controlled with FLP4 commands as listed in chapter 6.
As with all Flashlink modules, stored configurations in the Multicon controller will be applied

to a module that is plugged into a running system, provided that the switch SW2.8 is off and
that the last module present in the system was of the same type.

A module with SW2.8 on, plugged into a running system will overwrite the stored
configuration in the Multicon controller with its own configuration.

3.1.1 Converter gain

The DIP switches are grouped as sets of three switches for each of the stereo converters.
The levels correspond to the maximum sine wave level, otherwise known 0 dBFS.

These values are chosen as being the most often used levels in the broadcast industry.
Custom values are available, contact Nevion support or your local sales representative. The
D/A converter gain setting has a 1dB resolution so the gains at 13.5 and 16.7 dB are
rounded up to 14 and 17 dB respectively.

3.1.2 A/D Internal Clock frequency

SW1.8 controls the A/D converter clock when there is no signal at the reference input. If the
switch is in the off position, the internal sample rate of the A/D converters is 48 kHz.
Otherwise, the internal sample rate of the A/D converters is 96 kHz.

3.2 Multicon control

The module may be monitored and controlled with the Multicon system controller. The
converter gains and A/D internal clock frequency may be remotely controlled through the
module’s configuration page of the system controller.

The AES digital audio input signal presence and the on-board power levels are presented on
the info page. Alarms are generated for AES input loss (including the external reference) and
power supply violations.

4 Connections

The standard backplane supplied with the ADDA-AES8 is the ADDA-AES8-C1.

This backplane uses the standard pin assignment for the female DB-25 and a similar one for
the female DA-15 as shown below.

5 Operation

5.1 LEDs

The module has four LEDs.

5.1.1 Status

The Status LED is green when the module is programmed and functioning normally. It will
turn red for 1 second when power is applied and then turn green. Orange indicates that the
module is not programmed, or is in the process of being programmed. It will turn red if there
is something wrong with the power supply levels.

5.1.2 Sync

The sync LED is green when the external AES sync signal is received correctly.
The LED is red if there is no input or the signal has errors.

5.1.3 AES input 1 & 2

The two LEDs function in the same way.
The LED is green when the corresponding AES signal is received correctly.
The LED is red if there is no input or the signal has errors.
The LED is orange if the signal is present but is not PCM encoded audio.

6 FLP4 commands

FLP stands for Flashlink Protocol. The current revision of this protocol is 4, hence FLP4. This
specification is available form Nevion support.

The following FLP4 block commands are used in the monitoring and control of the module.

 ablk
 pwr

6.1 ablk

The ‘ablk’ blocks correspond to the physical audio ports as follows.

Blocks 0 to 3 report and accept the ‘lvl’ keyword followed by the maximum input level in cBu

(dBu multiplied by 10).
i.e. ablk 0 lvl 240 cBu

Blocks 4 to 6 report input presence with the ‘freq’ keyword followed by the received sample

frequency or 'los' or 'lol'. Absence of signal is reported with 'los' while 'lol' indicates an
unrecognized sample frequency.

i.e. ablk 4 input freq 44 kHz

6.2 pwr

The ‘pwr’ blocks from 0 to 4 list the levels of the power supplies as measured by the

microcontroller.

 0 is the frame +5V
 1 is analogue +4.75V
 2 is the frame +15V
 3 is the frame -15V
 4 is digital +3.3V

The frame supplies are measured after the module fuses and filtering.

6.3 On-site re-programming.

The module may be re-programmed on site with a GYDA Multicon system controller.
Firmware will be provided by Nevion support when necessary.
