FRONT PANEL CONTROLS
1.
DOUBLE-BARREL™ MICROPHONE INPUTS
The S-6 features TWO 4-pin, lock ring type, microphone
inputs - front panel mounted and right side for co-pilot
use. Double Barrel jacks also allow simultaneous use
of stock microphone and an aftermarket microphone.
Microphone wiring is as follows:
Pin 1 : Ground
Pin 2 : Microphone Audio
Pin 3 : Transmit
Pin 4 : Receive
2.
(OFF)
VOL
SQ
(OFF): Turns the radio on and off. Rotate the control
counterclockwise until it clicks.
VOL: Volume. Adjusts the AF gain, or volume of the
receive audio. Turn clockwise to increase and counter-
clockwise to decrease.
SQ: Squelch. Used to eliminate background or “white”
noise when monitoring strong signals. To properly ad-
just the squelch circuit, start rotating the control slowly
clockwise until the received white noise disappears.
3.
MIC-G RF-G
MIC-G: Microphone Gain. Increases or decreases the
energy developed in the microphone amplifier circuit.
The gain increases as the control is rotated clockwise.
For optimum setting, press the push-to-talk switch on
the microphone and speak in a constant tone into the
microphone. A good test tone is to say the word “four” in
a long, drawn out tone. While speaking, rotate the mic
gain control clockwise until the meter needle reaches
maximum deflection. Next, rotate the control counter-
clockwise approx. 1/16 inch. The transmitter will now
be putting out its maximum rated power.
RF-G: RF Gain. Adjusts the receiver sensitivity to both
signals and background noise. This affects the distance
at which a signal can be detected. Turning the control
counterclockwise reduces the receiver sensitivity. This
is particularly useful in areas where large volumes of
traffic (signals) are present.

VOL DEL
TURBO
TM
Digital Echo is a Magnum radio exclusive
feature. The TURBO
TM
Digital Echo is louder, more ad-
justable, and better sounding than any other echo pro-
cessor available.
VOL: Echo Volume. Varies the volume or number of
echo repetitions. To increase the echo volume, rotate
the control clockwise.
DEL: Echo Delay. Varies the amount of delay, or dura-
tion of the echo repetition. Rotate clockwise to increase
the amount of delay and counterclockwise to decrease.
5.
DIM COR
DIM: Continuously variable dimmer control for front panel
lights and displays.
COR: The clarifier shifts both the transmitted and re-
ceived frequency in all modes. The COR (course) tun-
ing shifts a total of +/- 2.5 KHz.
6.
FREQUENCY: Rotate clockwise or counterclockwise to
select the desired frequency.
