Safety Warning: The Model 55 does not 
contain an AC mains disconnect switch. 
As such the mains cord plug serves as 
the disconnection device. Safety consid-
eration requires that the plug and associ-
ated outlet be easily accessible to allow 
rapid disconnection of mains power 
should it prove necessary.
As soon as mains power is applied, the 
Model 55’s power present LED will light. 
The Model 56 will go through its power-
up sequence lighting each LED in a rapid 
sequence. The power present LEDs on 
the talent amplifi ers will also light. 
The Over Current LED located on the front 
panel of the Model 55 should not be lit. 
If it is fl ashing, immediately refer to the 
Troubleshooting section of this guide. 
If everything appears to be functioning 
properly you are now ready to confi gure 
the system. 
Model 35 Stand Mounting
Included with each Model 35 Talent Ampli-
fi er is a nifty mounting adapter that allows 
the unit to be conveniently attached to a 
microphone stand. Please refer to the 
Installation Guide provided in the Model 
35’s shipping carton for details. 
Model 56 Mounting Options
The Model 56 Control Console includes 
provisions for mounting to microphone 
stands, equipment consoles, etc. To avoid 
“reinventing the wheel,” our products are 
compatible with the 25 Series components 
from OmniMount Systems, a supplier of 
fi nely engineered mounting systems. 
This fi rm makes many versions of the 
25 Series; one of which should fi t your 
needs. If you desire microphone stand 
mounting the following components would 
be appropriate: 25RST-25H Straight Tube 
Reverse Mount with Quick Release, along 
with a 25MA Microphone Stand Adapter. 
(If quick adjustment is not required the 
25RST Straight Tube Reverse Mount can 
be used in place of the fi rst item.) When 
connecting to metric-thread stands please 
contact OmniMount for the correct part 
numbers.
The design of the Model 56 did not 
allow the inclusion of threaded inserts, 
so holes of adequate size to allow
¼
-20
round head machine screws are provided. 
It is intended that screws of 
5
/
8
-inch length,
along with lock washers and machine nuts, 
will securely attach a 25 Series mounting 
clamp assembly. The cover of the Model 
56 will have to be removed to gain access 
to mounting holes. Be careful when select-
ing the mounting screws—exceeding the 
recommended 
5
/
8
-inch length will cause
the mounting screws to damage the Model 
56’s internal components.
Model 70 Interface
In most cases Model 35 Talent Amplifi ers 
will be used to drive headphones associ-
ated with a StudioComm installation. In 
special cases a line level signal may be 
required to interface the Model 55 Central 
Controller’s talent amplifi er output with oth-
er audio equipment. An example would be 
to use the Model 55 with an existing head-
phone system. The Model 70 Interface is 
used to convert the talent amplifi er signal 
to a stereo, balanced line level signal.
