Protecting Against Electrostatic Discharge – Static electricity can harm delicate
components on the AD-D96 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.
Clocks – The AD-D96 should have only one clock source. If running with the
internal clock, make sure SW2 is in the INT 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.
HV-3D OL Peak LEDs are set to illuminate at +22 dBu, that is 2dB below the
clipping point of the converter: (referenced to 0VU = –20dBFS). The analog
electronics can handle greater than +30dBu.
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-D96 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.
