Protecting Against Electrostatic Discharge
Static electricity can harm delicate
components on the AD-R96 MADI module.
To prevent static damage, discharge static
electricity from your body before you touch
any electronic components. You can do so
by touching an unpainted metal surface on
the HV-3R’s chassis.
Unplug the HV-3R’s AC power cord
before inserting or removing the
AD-R96 MADI module
SYNC LEDs – Indicates which MADI input is
active, locked and in sync. The left LED is
for optical, the right for coax connections.
Lock LED – Indicates when the internal AD
converter is locked to the MADI processor.
AES Clock OUTs – Not normally used in a
MADI system. Word clock or AES (J4/J5 on
board) is output on the BNC connectors.
AES Digital OUT – Eight channels of AES
format digital audio wired to Tascam
standard pin-outs. Always active. The AES
data is clocked by the MADI stream
Clocking and Sample Rate - the AD-R96
MADI defaults to 48kHz when there is no
MADI input connected. It will follow the
clock of the incoming MADI stream at 44.1,
48, 88.2 and 96kHz.
MADI channel counts are reduced by half
when running at 96kHz sample rates. Be
sure to take this into account when planning
your system capacity.
MADI OUT and IN – Multi-mode optical
fiber with an SC-Plug (IEC 874-19) or 75
ohm coax with a BNC connector.
The optical connectors are under the
removable black protective cover and are
not labeled. Outputs are on the left, inputs
on the right.
Optical and coax Out and In can be
connected simultaneously. The system will
automatically switch between whichever
input is actively carrying data. Outputs are
always active
MADI Throughput Delay – Latency is
three samples per MADI card at 48kHz and 6
samples at 96kHz (the amount of time is the
same for either).
A 64 channel system would have 21(42)
samples between channel 1 and 64. Take
this into account when using stereo mics.
Keep them in the same preamp if possible.
