Technical
Specifications
The telephone paging amplifier shall be a Bogen
Model TPU
1
5A, or equivalent, with a power rating of
1
5 watts. Distortion shall be less than 2%. Frequency
response shall be ±2dB from 70Hz to
1
2kHz for the
music channel and the page channel shall be shaped
for maximum intelligibility. Sensitivity shall be -20dBm,
600 ohms for the page channel, and 70mV for the
music channel. Signal-to-noise shall be -70dB ("A"
weighted). Tone control action shall be -3dB at
2.5kHz; 6dB per octave; the low-cut filter action shall
be -3dB at 350Hz; 6dB per octave. The amplifier shall
provide a 600-ohm balanced page channel input, and
a 25-kilohm, unbalanced auxiliary/music channel input.
The page channel shall incorporate automatic level
control (ALC) limiting output level change to +
1
,
-3dB with
1
5dB input level change (ref.-20dBm rated
input sensitivity). The amplifier shall also provide a
night ringer, which shall be triggered by an external
contact closure. Outputs shall be 25V, 70V, and 8
ohms balanced and transformer-coupled.
The amplifier components shall be completely solid-
state and the unit shall mount directly to a wall.
Electronic circuitry shall provide voice-activated mut-
ing of background music during a page. Amplifiers
that require the use of telephone system-supplied
external relays shall not be accepted.
Screw terminal barrier strips shall be provided for all
input and output connections. Individual controls shall
consist of Page Volume, Music Volume, Night Ringer
Volume, and Tone, all of which shall be screwdriver-
adjustable. A Peak Level LED indicator, Lo-Cut filter
switch and a circuit breaker shall be provided.
The amplifier shall operate from a
1
20V AC, 60Hz
power source. The unit shall be professionally fin-
ished (silver on black) and shall measure
11"
W x
2-3/4"H x 2-3/8"D. The shipping weight shall be four
pounds.
