Connections on the Rear Panel

1
1) AES IN 1 & 2 – These XLR connections accept AES/EBU input in the format selected
by the front panel AES parameter. When AES is set to SINGLE, each connection
accepts a discrete stereo input; when AES is set to DOUBLE, both connections used in
conjunction accept one stereo input.
2) AES OUT 1 & 2 - These XLR connections provide AES/EBU output in the format
selected by the front panel AES parameter. When AES is set to SINGLE, stereo output
is duplicated on each connection; when AES is set to DOUBLE, both connections used
in conjunction provide one stereo output.
3) S/PDIF IN/OUT – These RCA (Cinch) connections provide S/PDIF Coaxial Input/
Output
4) OPTICAL IN/OUT – These Toslink connections provide Optical input/output in the
format selected by the front panel OPTICAL parameter. Please see the section entitled
"About Digital Audio Formats and Format Conversion" for detailed information on the
formats provided.
5) OPTION CARD – This slot is reserved for Option cards which provide additional input/
output formats, such as FireWire.
6) VIDEO/WORD CLOCK IN – This BNC connection accepts both TTL Logic and
video black burst signals, according to the front panel CLOCK SOURCE parameter.
When CLOCK SOURCE is set to Video, the video format (PAL, NTSC or B&W) is
automatically detected. The Video/Word Clock input is internally TERMINATED – no
external termination should be used.
7) WC OUT 1-6 – These BNC connections provide TTL logic level word clock outputs.
Outputs 1-4 transmit clocks whose frequency equals the SAMPLE RATE, while Outputs 5
& 6 may be set to transmit a clock whose frequency is a multiple of the SAMPLE RATE.
8) AC IN – This IES connection accepts an AC input of 100 to 240 VAC at a frequency of 50
to 60 Hz.
