INSTRUCTION MANUAL
fi FEATURES
The MC-85 is designed for use with a wide range of commu-
nication equipment. The microphone's silver and dark gray
colors match the various KENWOOD communication units.
1. Employs a high quality uni-directional electret condenser
microphone. Gives excellent high frequency characteris-
tics and prevent pickup of undesirable noise.
2. Complete with an UP/DOWN switch and an electronic
LOCK-PTT switch.
3. The microphone has an output select circuit and can be
connected to three transceivers.
4. Because of the built-in limiter circuit, voice can be heard
more clearly. This makes it ideal for DX operation.
5. Microphone output is indicated by a level meter.
6. A sound quality select circuit is provided, which can be
switched between DX and local operation.
7. Power ON/OFF and transmitting are indicated by LEDs.
@ Controls and their functions [Fig-1]
1) Mic unit
The MC-85 is a uni-directional electret condenser
microphone. A windscreen is supplied.
2) Gooseneck
The MC-85 uses a gooseneck to hold the mic unit.
This allows the microphone to be easily repositioned.
3) MODE/POWER switch
Placing the POWER switch on turns onthe unit and
lights the LED (11). Switching to COMP. IN activates
the built-in compressor.
4) TONE switch
Used to change transmitter sound quality. For normal
communications, set the switch to NORMAL. When
additional clarity is needed, set the switch to LOW
CUT.
5) PTT switch
Depressing the PTT switch allows transmission and re-
leasing it switches the unit from transmission to re-
ception. There is no need to depress it forcefully.
LOCK switch
Depressing the switch once allows transmission. De-
pressing the switch again returns the unit to the receive
mode. This switch is used for long transmissions,
Use either switch (5) or (6) according to the type of
communications. When either of these switches is used
for transmission, the LED PTT/LOCK (12) lights red.

7) Audio tevel compensation control
This slide control! is used to control the ievel of the
built-in Audio Level Compensation.
8) Mic level control
This slide control is used to control the mic gain.
9) Output select switch eo .
Depressing the switch selects the output. The output
cable is connected to I. Therefore depress the I switch.
For use of switch I or UI, an optional PG-4 should be
connected to the MC-85. Then, up to three trans-
ceivers can be used with this microphone.
10) Level meter
Indicates the output level.
11) POWER ON LED
Lights when the power is ON and shows that the MC-85
is in the operation.
12) PTT/LOCK LED
Lights when the PTT or the LOCK switch is ON and
indicates transmission mode.
13) UP/DOWN switch
This switch interconnects the transceiver's UP/DOWN
functions and shifts the operating frequency up or
down. For a transceiver without an UP/DOWN tuning
function, the operation of this switch is disregarded.
14) Mic connector
The MC-85 employs a standard 8-pin plug for connec-
tion. When connecting the microphone to a mic jack
other than 8-pin, use an adaptor plug. Fig. 2 shows the
internal wiring connection. Table 1 shows the relation-
ship between the microphone and Kenwood equip-
ment.
