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.

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.

Connecting MONO/SUBWOOFER speaker (SUB/MONO OUTPUT)

3. Application

3-1. Connecting MONO/SUBWOOFER speaker (SUB/MONO OUTPUT)

1 Plug the external speaker’s audio cable to the 6.3mm or 2P PHOENIX jack on the rear

panel. The speaker’s impedance must be 4Ω or more. When using 2P PHOENIX for

connection, please accord with the positive (+) and negative (-) polarities.

※IMPORTANT! Either 6.3mm or 2P PHOENIX jack can be connected.

2 Slide the switch to MONO(BYPASS) mode when connecting to a mono speaker. SUB

mode to a subwoofer.

3 There is crossover control on the rear panel for external subwoofer speaker. This

control can decide the frequency to amplify or mute the audio. Only audio below the

crossover frequency will be amplified to the subwoofer speaker.

4 Turn on the power and then adjust SUB/MONO volume control on the front panel to a

desired level.
