2-2-1. Parts and functions
Channel synchronization of the receiver and transmitter
Align infrared areas of the receiver and transmitter within 10~30cm.
■Changing receiver’s channel
1 Press the synchronization
button of the transmitter.
►
2 The transmitter's LED will
grow to denote
synchronization signal
transmitted.
3 The channel number on
the receiver’s LED will
become the same as the
transmitter’s, which
means the receiver has
been successfully
synchronized.
■Changing transmitter’s channel
1 Press the SYNC button of
the receiver.
►
2 The transmitter's LED will
grow to denote
synchronization signal
received.
3 The channel number on
the transmitter’s LCD will
become the same as the
receiver’s, which means
the transmitter has been
successfully
synchronized.
If it doesn’t work check that you have the IR sensor panels aligned, that they are facing each
other, devices are within 10~30cm of each other, and try again.

Using the wireless receiver
2-2-2. Channel scanning
For an interference- free operation, a cleaner channel might be necessary if the current one
receives too much interference. To operate the scanning:
1 Press ▼(down) or ▲(up) button to make
the frequency icon appear on the
bottom.
2 Hold SET button until this icon
flashes to denote readiness for setting.
3 Press ▼(down) or ▲(up) button to find
and locate a clear, interference- free
channel.
4 After a channel is chosen, press SET
button or wait 5 seconds to store the
setting.
2-2-3. Squelch (SQ) setting
When interference is encountered try reducing the sensitivity of the receiver, thus less
susceptible to interference. To operate the squelch setting:
1 Press ▼(down) or ▲(up) button to turn to
the squelch setting page.
2 Hold SET button until this icon
flashes to denote readiness for setting.
3 Press ▼(down) or ▲(up) button to select
a new squelch level between 01 and 10.
The default level is 01.
4 After a level is chosen, press SET button
or wait 5 seconds to store the setting.
Since increasing the squelch level will also reduce the reception distance, it’s recommended to
choose the lowest level that can eliminate the interference.
If this still does not solve the problem it means this frequency is not suitable. Adjust the squelch
back to its default level (LE-01) and use the scan function to locate a clear, interference-free
channel.

2-6. EQUALIZER for WIRED and WIRELESS MICROPHONE and MUSIC
EQUALIZER adjustment is actually used to increase or reduce the high/low frequency
component of the speaker's restored sound. It is so-called raising or attenuating TREBLE/BASS
via frequency-specific volume knobs to improve human voices or make musical instruments’
sound more prominent. According to the scale marks on the panel, clockwise adjustment is to
increase and boost and opposite direction to decrease and attenuate.
Adjust the level of high frequency (TREBLE) and low frequency (BASS) respectively. All signals
have been balanced by the high and low sounds after entering the amplifier so it is not
necessary to adjust the EQUALIZER during the output to the speaker. It is recommended to
maintain the position of BASS and TREBLE at just 12 o'clock.

Adjustment reference:
◼BASS: It is the basic part of the sound. It accounts for 70% of the
entire audio energy and is an important component to display the
music style. When appropriate, the BASS is relaxed and the sound is
full and soft. If you feel the sound is thin, you can moderately
increase the BASS. If you feel the sound is muffled, not clear, or too
nasal, you can moderately reduce the BASS.
◼TREBLE: It’s the frequency that affects the sound layering. If you feel that the sounds of
instruments such as Piccolo and Flute are too prominent, or the tooth sound of the voice is
too heavy and the tone is sharp, you can moderately reduce the TREBLE.
2-7. VOICE PRIORITY
Voice Priority operation is only necessary when CD/USB/MP3 is playing.
When the Voice Priority switch is ON, the ducking function will be activated. While the music is
playing, a voice input from either a WIRED or WIRELESS MICROPHONE will temporarily
override and lower the volume of the background music and voice could be heard more clearly.
Background music will return to its original setting when no audio input is entering the
microphone after certain seconds. However, if the microphone is not switch off, the reentering of
music into the microphone will also activate the voice priority function.
