Receiver
1. RF/AF: RF indicates strength of the received microphone signal and AF indicates audio
signal level of the microphone channel 1.
2. FREQUENCY: Frequency of the microphone channel 1 and 2.
3. RF/AF: RF indicates wireless signal strength and AF indicates audio signal level of the
microphone channel 2.
4. VOLUME: Volume controls for microphone channel 1 and 2. Setting microphone
volume too high, may cause distortion in the microphone input of mixer or mixing
amplifier. Set volume lower from the receiver if microphone sound is distorted. Typical
position from 12 to 2 o’clock.
5. POWER: Turn on the power for the receiver.

Functions
1. GRILL: Removable metal grill protects a cartridge from
damage and an inner foam filter reduces wind, breath
and pop noises.
2. CARTRIDGE: Removable cartridge.
3. LOW BATTERY INDICATOR: Light blink once when the
microphone is turned on. If light turns on during
operation, battery level is low. If battery level is low,
wireless microphone signal degrades which may cause
dropouts or complete signal loss. Please charge batteries
immediately or replace with new one.
4. POWER SWITCH: Turn the microphone on or off.
5. BATTERY COVER: Battery compartment for two
rechargeable AA batteries. Remove batteries if the
microphone is not used for long time. Microphone
frequency marked on the sticker on the battery
compartment.
6. CHARGING CONTACTS: Charging contacts on the
bottom of the wireless microphone. Do not charge non-
chargeable batteries!
Operation
1. Open battery cover by turning the cover
counterclockwise. Install two rechargeable ’AA’ batteries
and close the cover. Pay attention to the correct polarity.
2. Turn on the microphone by sliding power switch to ”ON”
position. Power indicator will blink once and then turns
off. This indicates normal operation.
3. Receiver’s RF level indicator should turn on now to
indicate connection between the wireless microphone
and receiver.
4. If power indicator light turns on during operation, battery
level is low. Please replace with new batteries
immediately.
5. Turn off the microphone by sliding power switch to ”OFF”
position.

5. Connect 12 V / 1 A power adapter included in the box.
Operation
1. Connect 12 V / 1 A power adapter to the DC jack on the back side of the charging dock.
2. Install rechargeable ’AA’ batteries into the microphone and put the microphone into one
of the charging sockets.
3. Light is on while the battery is charging and turns off after battery is fully charged.
Note! Do not charge non-chargeable batteries. Non-chargeable battery will overheat and
seal breaks causing the battery to leak or explode.

Operations Before Connecting the Receiver
1. Install antennas to the back panel of the receiver.
2. Connect 12 V / 1 A power adapter to the DC input of the receiver.

Getting Connected
8
Connection can be made from Mixed Output using unbalanced 1/4" TS plug cable included
in the box. In this case both microphones are connected using only one cable, so it’s not
possible to change microphone sound settings individually for each channel in the mixer.
Please check the connection example on the page 9.
Alternatively both microphones can be connected separately to the mixer using Balanced
Outputs. In this case two cables are used to make the connection, so it’s possible to
change microphone sounds settings individually for each channel in the mixer. The
connection can be made using the following cables depending on the microphone input
connector type:
ŸXLR female - unbalanced 1/4" TS plug cable,
ŸXLR female - XLR male cable,
ŸXLR female - balanced 1/4" TRS plug cable
The last two cables are balanced, which reduces interference picked up on the cables.
Please check the connection examples on the page 10-12.

1. Connect the receiver to the microphone input of your mixer or mixing amplifier.
2. Turn on the receiver and your mixer, mixing amplifier or karaoke player.
3. Install batteries into the wireless microphone and turn on the microphone. Signal level
indicator on the receiver should activate to indicate connection to the receiver. Note! If
light on the microphone turns on during operation, recharge or change the batteries
immediately to ensure interference-free operation. More detailed guide of using the
wireless microphone on the page 6.
4. Set volume from the receiver to 12 o’clock position and adjust microphone volume from
your mixer or mixing amplifier until the microphone sounds good.
Note! Setting microphone volume too high on the receiver may cause distortion on the
microphone input of your mixer or mixing amplifier. In case the sound is distorted, decrease
microphone volume from the receiver. You can compensate decreased microphone volume
by increasing volume from your amplifier or mixing amplifier.
