(6) S/PDIF Digital Input - This phono (RCA) connector accepts incoming 24-bit S/PDIF digital audio
signals of up to 192kHz from compatible hardware (the copy-protection, pre-emphasis, and
consumer/professional bits are ignored). This input can be used for either digital audio with clock or
for digital clock only. When the Clock knob ( see #3 on page 4) is set to AES/SPDIF and the Digital
Outputs Source Select knob ( see #9 on page 8) is NOT set to AES/SPDIF, the audio portion of the
signal is ignored. ( see page 29 for more information)
(7) S/PDIF Digital Output - This phono (RCA) connector transmits 24-bit S/PDIF digital audio signals
of up to 192kHz to compatible hardware. The copy protection bit and pre-emphasis bits are cleared,
and the consumer/professional bit is set to “professional.” ( see page 29 for more information)
(8) Word Clock Outputs - These four electrically independent standard 75-ohm BNC connectors
transmit independent high-quality word clock at the frequency specified by the Sample Rate Select
knob. ( see #4 on page 6) Four outputs are provided so the 2192 can be used as the master clock
source for multiple devices simultaneously without cascading the clock through external devices,
which can degrade the signal. The word clock signal on each of the four outputs is identical and is
phase aligned to the clock source to allow cascading multiple units without sample skew. ( see
page 29 for more information)
(9) Word Clock Input 1 - This standard 75-ohm BNC connector receives word clock input for external
synchronization when the Clock knob ( see #3 on page 4) is set to Word 1. ( see page 29 for
more information)
(10) Word Clock Input 2 - This standard 75-ohm BNC connector receives word clock input for external
synchronization when the Clock knob ( see #3 on page 4) is set to Word 2. ( see page 29 for
more information)
(11) 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 ( see #3 on page 4) is set to ADAT and the Digital Outputs Source Select knob
( see #9 on page 8) is NOT set to ADAT, the audio portion of the signal is ignored. ( see page 29
