Connecting Audio
Your Profile Video File Server can have one or two Audio I/O boards installed. All units have
at least one Audio I/O board, called Audio Signal Processor Board (or ASPB), which provides
16 channels of audio I/O. A second ASPB can be installed, adding 16 more channels for a total
of 32 channels of audio I/O.
If you have two Audio I/O boards installed, the first one (or ASPB1) resides in the lowest
numbered board slot and is labelled “AUDIO I/O IN/OUT CH 1-16”. The second ASPB (or
ASPB2), if installed, is in the higher numbered board slot and is labelled “AUDIO I/O IN
OUT CH 17-32”. Refer to the rear panel labels or Tables 1-2 through 1-6 in Chapter 1, pages
1-9 through 1-13, to determine the slot location of these boards in your system.
The Audio Signal Processor Board (ASPB) can be configured to operate with analog, AES/
EBU digital, and digital embedded (SMPTE 272M Level A) audio. If you are using only
embedded audio, no interface chassis is required.
An interface chassis is required for Analog and AES/EBU Audio. Table 2-1 contains a
summary of interface chassis available.
NOTE:
- Interface chassis must be connected to both ASPBs for operation with 32 channels
of analog or AES/EBU digital audio.
- To determine if the PAC 200 Analog Audio Chassis is a PAC 208 or PAC216, look
at the identification tag toward the rear on the left side of the chassis.

(Ch 9 to 16)
ASPB audio channels 1 to 8 are always
assigned to PAC208 analog channels 1 to 8.
ASPB audio channels 9 to 16 are always
assigned to PAC208 AES/EBU digital
channels 9 to 16.
PAC216
(includes PACXLR
breakout chassis) 16 16 The 16 ASPB audio channels are divided into
four audio groups (4 channels each). You can
assign the input for each audio group to either
the analog or digital inputs of the PAC216.
For example, the input to ASPB channels 1 to
4 can be assigned to analog input channels 1 to
4 or digital input channels 1 to 4 on the
PAC216. The ASPB output channels 1 to 16
are always assigned to both analog and digital
output channels 1 to 16 on the PAC216.
XLR216 none 16 Provides digital audio interface using XLR
connectors.
BNC 216 none 16 Provides digital audio interface using BNC
connectors.
