This amplifier uses either two lead-acid batteries or one lithium battery which can be identified
by LEAD-ACID and LI-ION on the panel top. The battery power can be identified by the meter
after the battery type. If the meter reads below 25%, the battery might not be sustainable for
long operation and need recharging.

Settings and Operations
2-2-3 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.
2-2-4 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.

2-7 EQUALIZER for WIRED and WIRELESS MICROPHONE and MUSIC
EQUALIZER adjustment is actually used to increase or reduce the high (4KHz│8KHz│16KHz)
/ medium (500Hz│1KHz│2KHz) / low frequency (63Hz│125Hz│250Hz) component of the
sound. It is so-called raising or attenuating TREBLE / MIDDLE / BASS to improve human voices
or make musical instruments’ sound more prominent. According to the scale marks on the
panel, sliding up is to increase and boost and opposite direction to decrease and attenuate.
Adjust the level of high frequency (4KHz│8KHz│16KHz), middle frequency (500Hz│1KHz│
2KHz), and low frequency (63Hz│125Hz│250Hz) 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 all
frequency bands at 0.

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.
◼ MIDDLE: Containing the low harmonics and overtones of most musical instruments. It is the
characteristic sound of snare drums and percussion instruments. The sound is clear and
bright when appropriate. If you feel the sound is blurred, you can moderately increase the
MIDDLE. If a phone-like sound appears, you can moderately reduce the MIDDLE.
◼ 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.

2-8 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.
2-9 CONTROL for vocal effect
APEX EVO has two major sound effects especially for WIRED and WIRELESS microphones,
REVERB and DELAY. After entering the CONTROL page, you will see six factory-preset
modes on the left for selection. Each mode comprises of specific values of REVERB and
DELAY and is not changeable. The DEFAULT mode sets both REVERB and DELAY at OFF
status.
For advanced setting, REVERB has four child effects and DELAY has two that may be adjusted
to match expected effects.

2-9-1 REVERB
This function can add extra depth to the sound of WIRED or WIRELESS microphones to create
a realistic acoustic ambience. You can control the reverb on the REVERB area which includes
four child effects for adjustment. REVERB can be turned on / off by the ON/OFF button.
