Tone Generator

Model TG4C

Multiple Tone Generator

The Model TG-4C Multiple Tone Generator is a compact, reliable unit designed to generate four distinct signals:

pulsed tone
slow whoop
repeating chime
steady tone

It is an excellent source for alarm or preannounce signals in public address or telephone paging systems. Each of the four signals may be applied continuously (until interrupted), or limited to a double- burst (except for the steady tone) for preannounce applications. Signals are triggered by an external device providing a contact closure. The output level and pitch control are adjustable.

The TG-4C will accept a Hi-Z input from a program source, such as a tuner, turntable, cassette player, etc., and will maintain precedence over the program material for the duration of the contact closure.

The unit may be powered from any 12-48VDC source, positive or negative ground. An accessory AC adapter (Bogen Model PRS-40C) is available for operation from a 120VAC, 60Hz source. The Bogen Model WMT-1A Line-Matching Transformer is available for standard 600-ohm telephone line connections. All connections are made at conveniently located screw terminals. Ruggedly constructed, the TG-4C is fabricated of steel and is finished in silver gray.
