Receiver installation
1. For best operation, the receiver should be at least 1m
above the ground and 1m away from a wall or metal
surface to minimize reflections.
2. The transmitter should also be at least 1m away from a wall
or metal surface to minimize reflections. The transmitter
should also be at least 1m away from the receiver.
3. Keep antennas away from noise source such as motors,
automobiles, neon light as well as large metal objects.

Audio output connection
There are two audio outputs on the back of the receiver, Mic-level balanced and Line-level
unbalanced. Use audio cable for the connection between the receiver and the amplifier/mixer.
Unbalanced audio connection: If the amplifier/mixer has a 6.3mm φphone jack, connect a
cable from the 6.3mm unbalanced audio output from the receiver to the amplifier/mixer.
Balanced audio connection: If the amplifier/mixer has an XLR input, connect a cable from
the balanced XLR audio output from the receiver to the amplifier/mixer input.
Unbalanced audio connection (6.3φ phone plug)
Balanced audio connection (XLR plug)
Rack mounting
The receiver can be cabinet-mounted by either one or two units. If only one receiver is to be
mounted, an optional kit is available and it's installed as shown in Fig 1. If two receivers are to
be mounted, they can be assembled by another kit and installed as shown in Fig 2.

To prevent other user from turning off the power, you may slide this switch to the right to lock
the microphone on stand-by or mute status. Slide to the left to unlock.
Battery installation & indicator
This microphone requires 2 x AA batteries to operate.
To install, remove the battery cover and slide the batteries into the battery compartment &
replace the battery cover.
Note: Batteries contain a corrosive acid that may leak and damage the microphone when
stored for a long period. Batteries should be removed from the microphone before storing
without use for more than 4 weeks.
When the microphone is switched ON, a blue LED②will blink once to denote the batteries
installed are in good condition. If the LED remains illuminated, it means the batteries are
weak and require replacement.
Channel synchronizing of the receiver and microphone
1. Unscrew the microphone’s lower housing
and then press and hold the synchronizing
button until LINK flashes on the LCD.
2. Press and press and hold the receiver’s
SYNC button until the frequency icon
appears. After successful channel
synchronizing, this icon will disappear
automatically.

select AKLN (alkaline) when microphone is intended for charging as alkaline battery isn’t
rechargeable. Wrong battery selection will result in battery sensing electronics to display wrong
and misleading status information.

Important: Lower output power will reduce the RF transmission distance and higher output
power will extend the possible RF transmission distance. However, higher output power places
slightly more load on the battery and will reduce operating duration faster than lower output
power.
