Model 35 Stand Mounting
Included with each Model 35 Talent 
Amplifier 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 38 and Model 51 Mounting 
Options
The Model 38 Talent Amplifier and the 
Model 51 Control Console include provi-
sions 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 
finely engineered mounting systems. This 
firm makes many versions of the 25 Series; 
one of which should fit your needs. If you 
desire microphone stand mounting the fol-
lowing components would be appro-priate 
for English-thread applications: 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 first 
item.) When connecting to metric-thread 
stands please contact OmniMount 
for the correct part numbers.
The bottom surface of the Model 38 Talent 
Amplifier contains two threaded inserts 
that will accept English-standard ¼
-20
screws. Using two,
5
/
8
-inch long, round-
head machine screws, the 25 Series clamp 
assembly can be directly attached. The 
cover of the Model 38 does not have to 
be removed.
The design of the Model 51 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 intend-
ed 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 
51 will have to be removed to gain ac-
cess to mounting holes. Be careful when 
selecting the mounting screws—exceed-
ing the recommended 
5
/
8
-inch length will
cause the mounting screws to damage the 
Model 51’s internal components.
Remote Control Inputs
The Model 51 allows you to connect two 
external switches or contact closures to 
enable system functions. Input 1 allows 
either a remote talk to studio or a remote 
control room source select function to be 
implemented. Input 2 allows a remote talk 
to phones function to be implemented. 
Using the remote “talk to” functions, it may 
be useful to install switches at a producer 
or director location. The Model 51 con-
tinues to provide local talk to studio and 
talk to phones access even when external 
switches are connected.
The required connector is a ¼
-inch
3-conductor phone plug. Tip is talk to 
studio or control room source select, ring 
is talk to phones, and sleeve is common.
