Mm FEATURES
The MC-60A microphone is designed expressly for use with
your amateur communication system. It provides excellent
performance when used with any KENWOOD transceiver,
thereby upgrading your existing system.
The zinc die-cast base offers high stability, and is complete
with a feather-touch PTT switch, rocker UP/DOWN switch,
an impedance selector switch and a built-in preamplifier.
NOTE: For UP/DOWN switch operation, refer to your
transceiver's manual.
CAUTION:
— 1. The microphone is constructed of precision parts. Do not
—————reat-t—gontiy:
open the microphone, as it may result in serious damage.
2. The microphone is sensitive to shock and vibration.

“© OPERATION
The MC-60A is equipped with a PTT switch for easy transmit/
receive changeover. The PTT switch can be locked, if desired
- by pressing the Lock key. To unlock the switch, simply
press the Lock key once again. The Mic on/off, Lock, and
PTT switches are all in parallel.

E INSTALLATION
1. Battery Installation (Fig. 2)
1. Remove four screws as shown.
2. Install two alkaline AA cells (not NiCd). Observe
polarity.
3. Reassemble base unit.
NOTE: 1. Radios with power available at the mic con-
: nector (for autopatch microphones) will not
require batteries.
2. The preamp on/off switch is located on the
underside of the base unit. The preamp is on
in the forward switch position.
2. Connection to your transceiver.
1. Slide the microphone into the plastic bracket.
2. Connect the short base mounted cable to the rear of
the microphone.
3. Connect the retractile cord from the base to the
transceiver. |
4. The microphone may also be used separate from the
base unit, by connecting the retractile cord directly
to the mic. However, the preamp is located in the
base unit. Preamped operation is not possible with a
direct transceiver hookup.
5. The MC-60A is supplied with a standard PG-4C 8 pin
to 8 pin retractile cord. For radios with a four pin mic
connector, use a PG-4A (4 pin to 8 pin) option cord.
For radios with a six pin mic connector, use a PG-4B
(6 pin to 8 pin) option cord. _ |
пес? the retractile cord directly to the microphone, and
use the slide-switch on the microphone for transmit/
receive changeover.
e Impedance selection |
The microphone impedance is selectable between 5000
and 50kQ by using the slide-switch on the microphone
regardless of whether the stand is used. Most Trio-
Kenwood HF products are 50k. Some will operate from
500-50ks2. All VHF and UHF mobile radios are 5002
impedance. |

e UP/DOWN switch
The UP/DOWN switch on the base is used to select the
transceiver's operating frequency.
Microphone Preamp vo
This microphone may be used with any Trio-Kenwood
radio. It is intended especially for FM and SSB mobile
radios. The preamp is controlled by the bottom mounted
switch on the base unit. Sliding the switch forward places
the preamp on. Sliding the switch to the rear bypasses the
ON@POFF preamp and disconnects the batteries. With the preamp
» switch on, power is always on so the microphone may be
(Black) used with VOX operated equipment. |

P.T.T. when not in use. (The amplifiers draw approxi-
