The Model 717 Microphone Equalizer / Audio Interface provides a convenient means of shaping your transmit audio as well as interfacing your radio to line level signals and external PTT switch, such as a footswitch. This device was designed so that older TEN-TEC transceivers and many other older transceivers could be used or modified to be used with the newer style Dynamic microphones on the market today.

 

High and low frequency cut / boost controls plus a mic level control on the front panel provide the means for improved audio quality and level. A front panel 8 pin microphone connector allows direct interfacing with microphones adhering to the TEN-TEC and Yaesu pinout standards.

 

Note: A 4 Pin XLR connector with cable and proper connector for the radio requested will be shipped with the order. Any custom modifications to this cable or connectors for use with other equipment is the responsibility of the buyer.

 

On the rear panel, two 1/8” phone connectors allow connecting an external PTT switch and line level audio input. The line level input level is adjustable via a rear panel gain control. Interfacing to the radio is accomplished via a 4 pin XLR male connector also on the rear panel. On the rear panel is a DC power connector which requires 12 – 15 VDC (positive on center pin). A regulated wall transformer is provided to power this unit. TEN-TEC does not provide a connector for RJ-45 microphone inputs or ¼” stereo style microphone connectors.

The 717 does not provide a bypass function for microphone audio.  When the 717 is turned on, it amplifies your micphone audio.

    excellent little microphone equalizer...does the job.
    I use it between my TT Eagle and 709 microphone to emphasize the lows a bit for good transmit audio.


  2. Ten-Tec Model 717 Microphone Equalizer - Audio Interface Review

    Posted by Garner W Powers Jr on 3rd Sep 2013

    I purchased the Ten-Tec 717 Microphone Equalizer - Audio Interface to interface a Ten-Tec 708A dynamic 8 pin desk microphone to my Ten-Tec 526 6N2 transceiver (4 pin polarizing Electret Mic input). The entire install process took
    Ten minutes. I set TT717 Level at 11 o'clock, Low & High Boost at 9 o'clock and TT526 Mic control to 11 o'clock. Every contact I made gave me excellent audio reports. Kudos to Ten-Tec and many thanks to Paul in Customer Service for suggesting the TT717.
