- 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.

DO NOT NETWORK THE POWER SUPPLY UNIT WITHOUT CONNECTING THE WHOLE EQUIPMENT SET WITH CABLES AND EARTHING IT.

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.

WARNING! IMPROPER POWER SUPPLY MAY CAUSE DAMAGE OF THE PRODUCT!

INSTALLATION

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).

TROUBLE AND COUNTERMEASURE

Problem	Possible reason	Elimination recommendations
Microphone is not working	Power supply unit or mixing console is not connected to the power line.	Check your power supply network connection.
	Power is not turned on on the mixing console or on the power supply unit.	Check the corresponding buttons on the mixing console and power supply unit.
	Microphone is not connected to the power supply unit or the power supply unit is not connected to the mixing console.	Check that the cables from the microphone to the power supply unit and from the power supply unit to the mixing console are connected correctly (see page 12).
	The 110V/220V switch is in a position that does not match the line voltage.	Check that the switch (6) is in the correct position (see page 11).
Sound distortion	Input sensitivity or preamplification of the subsequent amplifier are adjusted incorrectly.	Reduce the input sensitivity or preamplification of the next device so that there is enough modulation reserve.
	Transmission of structure-borne noise.	Use a suitable shock absorber (see page 10).
Unvoiced sound	Polar response curve is not taken into account.	Check that microphone is installed correctly. Microphone should be directed to the sound source with the side with Oktava logo.
