CONTACT MUTE Figure 1: Telephone Paging Amplifier This document describes the Bogen TPU250 250-watt Telephone Paging Amplifier (see Figure1). This is a full-featured, wall-mounted amplifier that provides inputs for dry loop 600-ohm telephone page signal, background music source, and low impedance microphone.Automatic music mute is provided when making a telephone... -

Rack Mounting The amplifier is designed for wall mount applications but can also be mounted in a standard 19" rack. The TPU250 amplifier weighs 31 lbs. NOTE: The amplifier will produce heat during operation which will rise and may cause problems for temperature-sensitive equipment mounted above it. Mount the amplifier near the top of the backboard (for wall mounting) or rack (for rack mounting) so that no other equipment will be above it. -

Page 10: Additional Power Amplifier
Additional Power Amplifier An external power amplifier can be used with the TPU250 amplifier. You must first add a resistor voltage divider to the telephone amplifier, as illustrated in Figure 8. Connect a patch cord to the high-level/high-impedance input of the booster amplifier. -
Page 11: Operation
Operation IMPORTANT: Before plugging the amplifier into an AC outlet, turn all volume controls to their full counterclockwise positions. Indicators POWER IND The POWER IND LED illuminates whenever AC power is applied to the amplifier (there is no power switch on the amplifier). PEAK LEVEL The PEAK LEVEL LED illuminates whenever the speaker output signal level approaches its maximum level. - Page 12 BASS and TREBLE Bass and treble controls are provided to adjust the high frequency and low frequency response of the paging system. Reference positions are provided for these controls. When set to these positions, the frequency response of the system will be flat. Set the controls to the customer’s satisfaction.
