Operating instructions

18
Superclock (256x) is not supported. Vari-speed sync is supported.
The 2192 BNC word clock inputs each provide an internal 75-ohm terminator.
Word Clock Input 1
This word clock input is used for external synchronization when the Clock knob (page 23) set to
Word 1.
Word Clock Input 2
This word clock input is used for external synchronization when the Clock knob (page 23) set to
Word 2.
ADAT Optical Digital I/O
The 2192 provides standard ADAT digital I/O via this optical interface.
At sample rates of 44.1kHz and 48kHz, only channels 1 and 2 are used. At higher sample rates,
industry standard S-MUX multiplexing is used to maintain high resolution transfers at higher
sampling rates. At 88.2kHz and 96kHz, channels 1-4 are used to achieve the stereo transfer. At
176.4kHz and 192kHz, all 8 channels are used for high resolution stereo audio.
ADAT Optical Input
This optical connector receives digital ADAT optical data from external hardware devices.
ADAT input can be used for either digital audio with clock or for digital clock only. When the
Clock knob (page 23) is set to ADAT and the Digital Outputs knob (page 27) is NOT set to ADAT,
the audio portion of the signal is ignored.
ADAT Optical Output
This optical connector transmits digital ADAT optical data to external hardware devices.
Analog I/O
Each balanced analog connector can individually isolate pin 1 from ground if desired via an
internal jumper block. See Ground Isolation Jumpers on page 22.
The analog inputs and outputs can be adjusted to calibrate signals for different levels as desired.
See Analog Line Trims on page 19.
Analog Line Inputs
Analog signals are input to the left and right channels via these balanced line-level female XLR
connectors. Pin 2 is hot. For unbalanced operation, Pin 3 can be grounded.
The analog inputs are calibrated at the factory so that an analog input level of +4dBu will output a
–18dBFS digital signal, for 18dB of headroom before digital clipping occurs.
Analog Line Outputs
Analog signals are output from the left and right channels via these balanced line-level male XLR
connectors. Pin 2 is hot. For unbalanced operation, Pin 3 can be grounded, and the output level
will be attenuated by 6db.
