Model TPU15A, or equivalent, with a power rating
of 15 watts. Distortion shall be less than 2%.
Frequency response shall be ±2 dB from 70 Hz to
12 kHz for the music channel and the page channel
shall be shaped for maximum intelligibility.
Sensitivity shall be -20 dBm, for the page channel,
and 70mV for the music channel. Signal-to-noise
shall be -70 dB ("A" weighted). Tone control action
shall be -10 dB @ 10 kHz; 6 dB per octave; the
lo-cut filter action shall be -10 dB @ 100 Hz; 6 dB
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 con-
trol (ALC) limiting output level change to +1, -3 dB
with 15 dB input level change (ref. -20 dBm 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 mount directly to a
wall. Electronic circuitry shall provide voice-activated
muting 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 120V AC, 60 Hz
power source. The unit shall be professionally
finished (silver on black) and shall measure 11" W x
