Analog Audio Configuration
Analog audio backplanes are equipped with Phoenix connectors that each
carry two balanced audio channels (typically left and right stereo). Inputs
are located on the left, and outputs are located on the right (as viewed from
the rear). Representative analog audio backplanes are shown below.

Note The bottom row of analog audio connectors are mounted upside down in
relation to the top two rows, due to internal board space limitations. The
removable connectors are wired the same regardless of row used.
Analog frames also offer a Dual Stereo configuration, which divide the
matrix into two groups with independent inputs and outputs. Inputs for
one group can only be routed to outputs of the same group, not to outputs
of the other group. The inputs and outputs of each group are labeled with
a leading number, 1- or 2-. Two Dual Stereo analog configurations are avail-
able, one with eight outputs per group
Figure 27 ), and the other with four
outputs per group ( Figure 28 ).
