SAFETY
INFORMATION
Before using the microphone, carefully read the operation manual.
Keep the manual in a safe place, accessible for all users.
Always handover the operation manual to third parties together
with the microphone.
Use the microphone only for its intended purpose in accordance
with this manual.
The liquid can get into the microphone, cause a short circuit
in the electronic components or damage the mechanical components.
Clean the microphone only with a soft, slightly moistened cloth.
Solvents or cleaning agents may damage the surface or enter
the product.
Do not expose the microphone to extremely low and extremely high
temperatures.
Do not open the microphone body by yourself. The warranty does
not apply to microphones, opened by customers themselves.

MICROPHONE INSTALLATION INTO SHOCK MOUNT
1. Screw the microphone shock absorber onto a sturdy, stable
stand (Fig. 1).
2. Insert the microphone from above in the inner shock absorber
ring and fasten it to the ring with a nut on bottom. To turn the
microphone, use the butterfly thumb screw (Fig. 2).

power supply preparation
In the front panel, there are the indicator lamp (1), the input
connector (2), the output connector (3), on the back panel, there
are the mains connector (4) and the mains switch (5).
The mains voltage selector 110V/220V (6) is located on the bottom
panel.

The power supply unit PSU-103 is designed for conversion
of the mains voltage 220 V or 110 V into the voltage
supplying capacitor microphones with lamp prime amplifier.
The electric safety of the power supply unit meets the
requirements of IEC 60065-2011 for devices of I class.

CONNECTION
1. Set the switch (6) to the position corresponding to the voltage
of the network used.
2. Insert the pin plug into the power filter unit (4).
3. Connect the input terminal (2) to the microphone using the
supplied XLR-5 - XLR-6 cable.
4. To connect the output terminal of the power supply unit to the
mixing console use any XLR-3 microphone cable (Fig. 5).
5. Connect the power supply unit to the mains by plugging the pin
plug into a power outlet.
6. Turn on the power switch (5). The alarm indicator (1) will light up
on the panel.
7. Wait 15 minutes before starting work to warm up the lamp in the
microphone.

installation
Fig. 6
1. Install the microphone on the stand with a microphone clip
or shock mount.
2. Connect the microphone to the equipment using
a microphone cable.
3. Point the microphone toward the sound source.
4. In order to suppress external noise, make sure that there
are no sources of parasitic noise in the microphone active zone
(for example, computer fans).
5. In order to extend the life of the microphone, it is recommended
to use a pop screen when working with vocalists (Fig. 6).
