Digital to Analog Converter M•DA-824
A.) M●DA-824 OPERATION
The M•DA-824 is a two-channel module that converts digital audio to analog audio with word-lengths of
16, 20 or 24 bits at sample rates of 44.1, 48, 88.2 or 96 kHz.
The M•DA-824 always clocks to the digital audio signal feeding its XLR input*.
In CrystalLock
or Narrow modes, it can lock to standard sample rates (44.1, 48, 88.2 or 96 kHz).
In Wide mode, the module can lock to vari-speed frequencies in the ranges of 42-100 kHz.
*Please Note: This means that the settings of the M•SYNC and any signal on its “Sync In” connector
have
no effect
on the M•DA-824. One benefit to this approach is that multiple M•DA-824’s in the same 4496
unit can operate asynchronously at different sample rates.
The 4496 is configured at the factory with the audio XLR outputs of the
M•DA-824
set for electronically
balanced line level operation (n4dBm).
DO NOT CONNECT Pin 2 or Pin 3 to Pin 1 in the
XLR for unbalanced operation without first setting the internal jumpers.
Doing so will cause
distortion; although the equipment is protected against damage from short-circuit. Please see “M•DA-824
SETTINGS” (page 16) for details on operating the M•DA-824 with Unbalanced outputs.
The analog outputs are electronically balanced, and the polarity can be configured by the front panel switch
for Pin 2 “+” (non-inverting) operation or Pin 3 “+” operation.
The setting which matches the default setting of the
M•AD-824
analog-to-digital converter is:
Pin 2 “+”
.
All analog audio and digital audio connections to the M•DA-824 are made with the three XLR connecters
on the back panel. There are no connections internal to the 4496 for these signals.
