AD-596 User Guide

Protecting Against Electrostatic Discharge
– Static electricity can harm delicate
components on the AD-596 board. To prevent
static damage, discharge static electricity from
your body before you touch any jumpers or
switches with the cover removed. You can do
so by touching an unpainted metal surface on
the API rack’s chassis.
Compatible Racks – The AD-596 is designed
to work in an API 500VPR or Lunch box rack.
If you are using another brand, be sure it
meets or exceeds the API spec.
The AD-596 power consumption is:
+130mA,–40mA
Clocks – The AD-596 should have only one
clock source. If running with the internal
clock, make sure SW2 is in the INT (default)
position and no external clock is connected.
Sync Signals on the BNC connectors should
conform to the AES-3id specification. AES-3,
through an XLR-to-BNC transformer (Neutrik
NADITBNC-F or equivalent) will work fine.
S/PDIF may work, but is not specified.
Sync signals can be either AES or Word Clock
(jumper selectable). AES sync should conform
to the above specs. Output sample rate will
match the sample rate of the applied external
reference sync. The range is:
32KHz ± 1%
44.1KHz -1% to 48KHz +1%
88.2KHz -1% to 96KHz +1%
DB25 Connectors conform to the Tascam pin
out. Please note you can’t use a pin to pin
DB25 cable to connect the digital outputs to a
DB25 digital input connector. A special cross
cable is required.
Peak Meters are set to illuminate at the
clipping point: +24 dBu (referenced to 0VU
= –20dBFS).
The toggle switch is spring loaded. When moved
to Pk Clr (peak clear), it will pop back to Pk Hld
(peak hold). It latches when moved between Pk
Hld and Norm.
Sample Rate can be set to 44.1k or 48k and
doubled to 88.2k or 96k with the 1X/2X switch.
This switch has no effect when the clock source
is switched to external
Lock LED illuminates when the unit’s clock is
locked to the external sync input.
Clock In is normally terminated to 75 ohms.
Remove jumper J8 if you are daisy chaining
clocks. The last unit in the chain should be
terminated.
Clock Out is a regenerated signal that removes
any jitter that may be present at Clock In.
True-
Lock-Clock – When set to External Clock,
the AD-596
will always revert to its internal
clock in the event that something happens to
the external reference. This way, if you lose
external clock, you won't lose the recording.
