Connecting 16 Analog/Digital Channels (PAC 216)
Figure 2-18 shows analog/digital audio connections for a 16 audio channel Profile
Video File Server using the PAC 216 version of the PAC 200 Profile Audio Chassis.
This Profile system has one ASPB (Audio Signal Processor Board) which provides
16 channels of audio I/O. The PAC 216 chassis and the PACXLR Audio Breakout
Panel, allows you to connect up to 16 analog audio I/Os and 16 digital audio I/Os
(eight pairs) to the Profile Video File Server.
The 16 ASPB audio channels are divided into four audio groups of four channels
each. You can assign the input for each ASPB audio group to either the analog or
digital input channels 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 four ASPB audio groups are always assigned to both analog and
digital output channels on the PAC 216.
When used in this configuration, the PAC200 is labelled PAC216 on the left side
panel at the rear of the panel.
NOTE: When using analog audio, you must use Configuration Manager to enable
analog audio inputs and to unmute analog audio outputs. See the Profile Family
User Manual for Configuration Manager information.
On the PAC200 (PAC 216):
• Connections are for analog audio channels 1-8, each with an In and Out.
• Connections are for four pairs of digital audio channels: 9/10, 11/12, 13/14, and
15/16, where each pair has an In and Out.
• The AES REF IN connector provides both a clock frequency and a framing
alignment reference, generally from a master sync generator, to the incoming
digital audio.
• The MONITOR LEFT/RIGHT connectors allow monitoring of one pair of audio
selected through software (see the Profile Family User Manual). This is an analog
output.
On the PACXLR Breakout Panel:
• Connections are for analog audio channels 9-16, each with an In and Out.
• Connections are for four pairs of digital audio channels: 1/2, 3/4, 5/6, and 7/8 where
each pair has an In and Out.
