Chapter 3 Installation Section
Expander pin assignment The following chart represents the audio and power connections vailable
at the 38 pin interface connector at the rear of the SSM.
The Assign 28 is a self contained, 8 output assign/subgroup module
designed to operate in conjunction with the Model SSM and SSM
Expander. The Assign 28 receives its signals from the 1/4" direct output
jacks at the rear of the SSM and SSM Expander. There are no special
requirements for installation and interface to the Assign 28 except to use
reasonable care in the layout of the audio cables.
It it recommended that the Assign 28 be installed directly above or
below the Model SSM. This will keep the cable lengths short, thereby
reducing the susceptibility to hums and buzzes caused by EMI
emissions.
A 1/4" T.S. (tip, sleeve) to 1/4" T.S. cable is required for each "direct
out" to "assign in" connection. If your mixer has 24 direct outputs (12
stereo pairs), this would require 24 cables for connection to the Assign
28.
The Assign 28 also provides 8 stereo effects returns that may be
interconnected to the 8 effects returns of the Model SSM. This would
require 16 cables. It is recommended that multipair harnesses be used in
lieu of numerous single cables.
For more complete installation details, refer to the documentation that is
supplied with the Assign 28.
If you have decided to use the expression pedal feature on the SSM, it
will be necessary to connect the cable and pedal to the system.
The optional interface cable is wired with a 6 pin DIN connector on one
end and four 1/4" plugs on the other end. The 6 pin DIN connector must
be plugged into the female expression pedal connector located at the rear
of the SSM. The four 1/4" phone plugs will be inserted into the
corresponding jacks on any standard passive stereo volume pedal.
