Microphone Model 705

The Ten-Tec Model 705 is an Electret desk microphone designed for use as a station microphone in commercial and amateur radio communications and in public address and paging installations. The microphone consists of a base section and flexible gooseneck mounted microphone. The Model 705 incorporates a momentary type Push-To-Talk (PTT) button (gray), a Push-On, Push-Off locking type button (black), electronic circuitry to switch the microphone on, a signal amplifier that adds 13 dB of gain to the output level, an attached output cable and a battery compartment for a 9 volt alkaline battery. The PTT circuitry allows switching transmitters and/or transceivers, that have a low voltage positive T/R lines, into transmit mode. A light emitting diode in the base signals the transmit mode.
