Features
* The Mid-Side system’ is employed to give excellent sound image and faithful stereo
sound reproduction with less “hole in the middle”.
¢ The directive angle between the left and right channels can be changed progressively
from 0° (monaural) to 150° according to the sound source.
* Electret condenser microphone with back-electret condenser capsules permits good
sound pick up.
* Mid-Side system
The sum of signals of the mid microphone unit (uni-directional) and side microphone unit (bi-
directional) and the difference between them are used for R and L channels respectively.

Battery Installation
When to replace the battery
When the power is turned on, the battery check indicator lights
momentarily. When the battery becomes weak, the indicator remains
dimly lit or does not light at all. In this case, replace the battery with a
new one.
Sony R6P (size AA) battery gives continuous operation of the
microphone for about 80 hours.
Notes on battery
To avoid damage to the unit caused by battery leakage and corrosion;
* Install the battery with correct polarity.
* Do not try to recharge batteries.
* Remove the battery if the microphone is not to be used for a long
period of time.
In case of battery leakage, wipe off any deposit in the battery
compartment before installing a new battery.

Battery check indicator
When the power/low cut switch is set to M from OFF, the indicator lights momentarily.
This indicates that the battery is usable.
Directive angle controller
Selects the directive angle between the left and right channels in accordance with
sound source or sound level.

@ Power voitage is dc 1.5V and fed with regulated dc power
supply from battery terminal.
Voltage is dc with respect to ground under no-signal conditions.
® no mark: POWER: M
* : Impossible measurement point
@ Voltages are taken with a VOM (Input Impedance 10MQ).
Voltage variations may be noted due to normal production
tolerances.
