Features
This microphone is a stereo microphone, attached externally to a video
camera, that can capture sound with high quality. It works with any video
camera that supports a microphone input terminal and an accessory shoe.
* The MS (Mid-Side) Stereo System enables a natural sound pick up,
delivering a stereo sound image with superb clarity.
* The directive angle (between left and right channels) can be set to 90* or
120° according to the sound source.
* A custom extension arm allows you to use the microphone apart from the
video camera, thereby cutting mechanical noise interference during
sound pickup.
|
Precautions
* The microphone should never be dropped or subjected to extreme shock.
* Keep the microphone away from extremely high temperatures and
humidity (above 40°C or 104°F).
¢ If the microphone is placed near loudspeakers, a howling effect (acoustic
feedback) may occur. If this happens, place the microphone as far as
possible from the loudspeakers, change the direction of the microphone
or decrease the speaker volume until the howling stops.

Installing the battery (See fig. Y)
1 Turn the cap counterclockwise.
2 Pull out the grip to open the battery compartment.
3 Inserta R6 (size AA) battery. |
Be sure to match the @ and @ on the battery with the @ and @
on the battery compartment.
Battery life
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 (SR) manganese battery gives continuous operation of the
microphone for about 200 hours.
Notes on battery
To avoid damage to the unit caused by battery leakage and corrosion;
e Install the battery with correct polarity.
e Do not try to recharge the battery.
e 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.
Connection (see fig. E])
Connect the L-shaped stereo miniplug to the MIC jack of your recording
equipment (videocamera recorder, etc.) as illustrated in fig. [.
Parts Identification and Uses (see fig. [9])
[1] Wind screen
Attach to reduce wind or breathing noise.
[2] Battery check indicator
When the power/ directive angle switch is turned from OFF to
ON, this 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.
Power/directive angle switch
Set the switch according to the sound source.
OFF Turns power off.
ON Turns power on.
90° Use to pick up a relatively narrower sound source
(instrumental solo, conversation, etc.), to provide a
clear stereo sound image focused on target source.
120° Use to pick up a relatively wider sound source
(orchestra, chorus, stage play, etc.), to provide a
natural stereo sound image with full reality.
The above gives guidelines for selecting an appropriate angle.
Although following these guidelines is encouraged, you can
freely select either angle according to your own preference.
