your operating position with crystal-clear electronically-enhanced audio. It also puts the fun back
into ham radio! Here are some of the high-tech features we think you'll enjoy:
Studio Quality:
The

is designed to drive two identical high
quality speakers installed three or more feet apart. This configuration improves intelligibility,
enhances frequency response, and dramatically increases spatial presence. Once your system is
set up, you'll think you're in a broadcast studio!
Speech Intelligibility Enhancer
TM

Every radio has different audio characteristics--and
everyone's hearing response changes over time. Our exclusive
Speech Intelligibility Enhancer
TM
tailors the sound of your radio especially for your ears. Young or old, you'll hear more clearly
than ever before!
Dual Amplifiers:
Two powerful monolithic IC amplifiers deliver deep, rich, undistorted audio
to high quality, hi-fidelity speakers (not supplied).
Adjustable Balance:
A front-panel
Balance
control aligns speakers for dead-center positioning
regardless of speaker placement or differences in ear sensitivity.

MFJ-616 very easy to set up and use.

behind the desk.

in or out without cutting off the
speakers. This feature is especially helpful for sound comparisons during the frequency set-up.
Multiple Outputs:

computer-style speakers. Also, a front panel switch turns off your speakers, the stereo headset
stays active. Front panel phone jack is attenuated to headset levels (deactivated with internal
jumpers).

Use transceiver's 13.8-volt supply, wall adapter, dedicated supply, or
12-volt battery to power your unit.
Rugged Construction:
Attractive all-metal cabinet, conservative component selection, and
space-age SMD circuitry ensure solid performance for years to come. Fully covered by MFJ's
"No Matter What" one year limited warranty.
