Connecting 32 Analog/Digital Channels (PAC216)

Figure 2-19 shows analog/digital interface connections for a 32 audio channel Profile
Video File Server. The 32 channel Profile system has two Audio I/O boards: ASPB1
and ASPB2. ASPB1 is in the lower numbered slot, and ASPB2 is in the higher
numbered slot. Refer to the rear panel labels or Tables 1-2 through 1-6 in Chapter 1,
pages 1-8 through 1-12, to determine the slot location of these boards in your system.
The 32 channel analog/digital audio configuration uses two PAC216 Profile Audio
Chassis. Each PAC216 chassis and PACXLR Audio Breakout Panel allows you to
connect up to 16 analog audio I/Os and 16 digital audio I/Os for a total of 32 analog
audio and 32 of digital audio I/Os.
The 16 audio channels on each ASPB 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 ASPB1
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 PAC216.
When used in this configuration, the PAC200s are 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 (PAC216) connected to ASPB1:
• Connections on the chassis are provided for analog audio channels 1-8, each with
an In and Out.
• Connections on the chassis are provided for four pairs of digital audio channels:
9/10, 11/12, 13/14, and 15/16, where each pair has an In and Out.
• Connections on the PAC XLR Audio Breakout Panel are provided for analog audio
channels 9-16, each with an In and Out.
• Connections on the PAC XLR Audio Breakout Panel are provided for four pairs of
digital audio channels: 1/2, 3/4, 5/6, and 7/8 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
audio output.
On the PAC200 (PAC 216) connected to ASPB2:
• Connections on the chassis are provided for analog audio channels 17-24, each
with an In and Out.
• Connections on the chassis are provided for four pairs of digital audio channels:
17/18, 19/20, 21/22, and 23/24 where each pair has an In and Out.
