Chapter 3 Installation Section
Power Supply
The Model SSM is supplied with the Model PS3-1.5 power supply that 
offers a variety of mounting options. The power supply may be placed 
on any flat surface, permanently affixed to a flat surface, or mounted on 
a single rack rail with the optional rack mount adapter. 
 
One of the primary reasons that the power supply of the SSM is external 
is to insure that the power transformer enclosed within the power supply 
chassis maintains a safe distance from the active electronics of the SSM 
and the Expander. For that matter, any power supply (especially the 
small wall mount supplies), power amplifiers, or any strong power field 
device should be kept at a reasonable distance from the SSM and 
Expander. It is also important to keep the above mentioned devices clear 
of all interface cables, audio cables and harnesses. 
 
The external power supply for the SSM does not provide an AC power 
switch. It is recommended the power supply be plugged into an AC 
strip that uses a power switch. 
 
The power supply should not be installed directly above or below the 
mixers. It is recommended that it be installed in the rear of the 
equipment rack, providing that it remains at a reasonable distance from 
the mixers and cables, and has adequate ventilation. 
 
The power supply normally generates a small amount of heat during 
operation. It is important that adequate ventilation is provided when 
planning the mounting location. 
 
The power supply may be wired to operate with 120 VAC, 220 VAC, 
230 VAC, or 240 VAC 50/60hz. Before applying AC power, you 
should verify that the voltage setting on your power supply is configured 
to match the AC requirements of your country. This procedure should 
be performed and checked by a qualified technician. 
 
Unless otherwise specified on the panel of the supply, the power supply 
is wired for 120 VAC 50/60Hz operation and uses a North American 
style AC plug. 
 
To gain access to the inside of the power supply, it will be necessary to 
remove the top cover. This is accomplished by removing the 4 screws on 
the bottom of the power supply chassis. Make certain that the power 
supply is unplugged from the AC before proceeding.
