Speakers

Speaker systems can be connected directly to the speaker out- put terminals. The amplifier provides outputs at 16-ohm, 25VCT, 25V, and 70V, and is shipped for use with unbalanced systems. Connect one lead to the terminal corresponding to the imped- ance of the speaker system and the other to the COM and GND terminals on the output terminal strip.

For balanced systems, remove the link between COM and GND.

Additional Power Amplifier

An external power amplifier can be used with the TPU amplifier. You must modify the output circuitry of the telephone amplifier by adding a resistor network, as illustrated below. Connect a patch cord to the high-level/high-impedance input of the boost- er amplifier.

Controls

APHEX®

The APHEX® control on the front panel adjusts the mix of the Aphex effect with the audio signal. Clockwise rotation of the control maximizes the effect. Counterclockwise rotation mini- mizes the effect.

To turn the Aphex circuit on or off, use the slide switch located in the connections bay (See INPUT CONNECTIONS).

Treble & Bass

The BASS control provides +/-9dB of boost and cut at 100Hz. The TREBLE control provides +/-9dB of boost and cut at 10KHz. Rotate controls clockwise to boost and counterclockwise to cut.

WMT-1A

Connect a Bogen WMT-1A accessory to the RCA jack labeled WMT-1A in order to feed a 600-ohm telephone line, LO-Z input or balanced Mic input of another amplifier. Refer to the instruc- tions furnished with the WMT-1A accessory for full information.

Operation

Power

Plug the amplifier line cord into a suitable outlet. The POWER LED will illuminate once power is applied to the amplifier. The unit remains in a power standby condition after power is applied.

PEAK LEVEL

The PEAK LEVEL LED will illuminate if the amplifier is driven into clipping. Adjust the output level of MIC VOLUME, PAGE VOLUME, MUSIC VOLUME, or RINGER VOLUME if the PEAK LEVEL LED remains ON.

TEL INPUT

VOX (Voice-Operated) SENS

The VOX SENSitivity control should be set so that only the desired signal is above the threshold level, while noise or unwanted signal is below it. When an input signal (such as voice) is detected, the music channel will be muted. To adjust the sensitivity of this circuit:

1.Rotate the control fully clockwise. While making a page announcement and talking at a low level, the sound should not be choppy nor missing parts of words. If it is choppy, or if intelligibility is poor, rotate the control counterclockwise to the point where the sound is clear and crisp (but not to the maximum counterclockwise position).

2.If the background music shuts down when no page

is in progress, rotate the control clockwise until the music is restored.

VARIABLE MUSIC MUTE

The MUSIC MUTE control adjusts the mute level of the background music when using the telephone paging channel. This control differs from the MUSIC MUTE terminals which mute background music during a microphone page (See Input Connections). The fully counterclockwise position results in maximum muting. The fully clockwise position results in minimum muting.

RINGER VOLUME

Adjust to the desired level - clockwise to increase, counter- clockwise to decrease the level.
