Bogen TPU15A Specsheet

The Bogen Model TPU15A is a unique 15-watt, wallmounting amplifier, specifically designed for telephone paging applications. This compact unit provides voice-activated muting of music when paging, completely eliminating the need for manual activation of switches and the use of external relays. The page channel features automatic output leveling (ALC) as channel input varies, which is particularly important in

telephone paging applications, where persons with varying voice levels and paging techniques have access to the system.

Installation and maintenance are simple; all connections, adjustments, and mounting are accomplished with a screwdriver.

Technical

Specifications

The telephone paging amplifier shall be a Bogen 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 control (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 systemsupplied 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 2-3/4" H x 2-3/8" D. The product weight shall be four pounds.
