Using the wireless receiver

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.

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.

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.

Volume and other settings

1. Turn on master POWER and then adjust its individual volume control to a desired level.

2. BASS / TREBLE equalizer (refer to P.11) can be adjusted individually.

Using an electronic instrument (INPUT 1 / INPUT 2)

1. Plug an electronic guitar or keyboard with a 6.3mm plug or XLR connector to INPUT 1 or INPUT 2 on the rear panel.
   

2. Slide the switch to LINE level.

3. Turn on the power and then adjust INPUT 1 (2) volume control on the front panel to desired level.

4. BASS / TREBLE equalizer (refer to P.11) can be adjusted individually.

Music audio input – MP3/MP4/phone (INPUT 3)

1. Plug the audio cable with a 3.5mm phone plug to INPUT 3’s 3.5mm stereo jack.
   

2. Turn on the power and then adjust INPUT 3 volume control on the front panel to a desired level.

3. BASS / TREBLE equalizer (refer to P.11) can be adjusted individually.

Music audio input – DVD player (INPUT 4)

1. Plug the audio cable with RCA R/L plugs to the INPUT 4’s RCA R/L jacks on the rear panel.
   

2. Turn on the power and then adjust INPUT 4 volume control on the front panel to a desired level.

3. BASS / TREBLE equalizer (refer to P.11) can be adjusted individually.

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.

increase or reduce the high frequency component of the sound
RANGE| -12 dB～+12 dB
DEFAULT| 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.

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.

Application

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.

5. BASS / TREBLE equalizer (refer to P.11) can be adjusted individually.

Connecting L/R stereo speakers (SPEAKER OUTPUTS)

1. Plug the external speaker’s audio cable to the 6.3mm or 4P PHOENIX jacks on the rear panel. The speaker’s impedance must be 4Ω or more. When using 4P PHOENIX for connection, please accord with the positive (+) and negative (-) polarities.
   ※IMPORTANT! Either 6.3mm or 4P PHOENIX jacks can be connected.
   
   

2. Turn on the power and then adjust L/R volume control on the front panel to a desired level.

3. There is a BALANCE control for balancing the output volume from the RIGHT and LEFT speakers when either speaker is too loud or too low.

4. BASS / TREBLE equalizer (refer to P.11) can be adjusted individually.

Connecting desktop / computer speaker (LINE OUT)

1. Plug the audio cable with 3.5mm plug from the LINE OUT’s 3.5mm jack on the rear panel to the desktop / computer speaker.
   

2. Turn on the power and then adjust LINE OUT volume control on the rear panel to a desired level.

Connecting external amplifier (MIXED OUT)

Plug the audio cable with RCA R/L plugs from the MIXED OUT’s RCA R/L jacks on the rear panel to an external amplifier.
