MODEL TPA-60/TPA-100
PAGING AMPLIFIERS
GENERAL APPLICATION INFORMATION
Wheelock's models TPA-60 and TPA-100 paging amplifiers are rated at 60 watts RMS and 100 watts RMS respectively.
These amplifiers afford a choice of five different inputs: two microphone inputs, one telephone input, and two background
music inputs. Only three of these inputs can be used actively at one time: one microphone, a choice of a second
microphone or telephone input, and a choice of one background music input applied through either AUX. 1 or AUX. 2.
Note that the background music will automatically be muted whenever a page is generated, from either a microphone or
telephone input.
An automatic volume limiter compensates for the varying voice levels and paging styles that may have access to a
system.
The amplifiers feature individual input volume controls, as well as a master volume control, individual treble and bass
controls, or low-cut horn protect switch, two input selector switches, an illuminated power on switch and a peak level
indicator.
Both models operate from 120 volts, 60Hz and have a power consumption of 180 watts (TPA-60) and 250 watts (TPA-
100). The units have an AC circuit breaker on the line input side, as well as a thermal breaker for overload protection on
the output. The AC circuit breaker is manually resettable. However, in the event it does not reset, have the trouble
investigated by an authorized service technician or return unit to the factory.
WARNING:
TO REDUCE THE RISK OF FIRE OR ELECTRIC SHOCK,
DO NOT EXPOSE THIS UNIT TO RAIN OR MOISTURE.
