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.
