2-5. TONE for WIRED and WIRELESS MICROPHONE and MUSIC
TONE 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 HIGH (MAX) / BASS (MIN)
via frequency-specific volume knob to improve human voices or make musical instruments’
sound more prominent. According to the scale mark on the panel, clockwise adjustment is to
increase / boost high frequency and decrease / attenuate low frequency, opposite to increase /
boost low frequency and decrease / attenuate high frequency.
Adjust the level of high frequency (MAX) and low frequency (MIN). All signals have been
balanced by the high and low sounds after entering the amplifier so it is not necessary to adjust
the TONE during the output to the speaker. It is recommended to maintain the position of TONE
at just 12 o'clock. default

Adjustment reference:
◼MAX (TREBLE): 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.
◼MIN (BASS): 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.
2-6. ECHO for WIRED and WIRELESS MICROPHONE
This function can add extra depth to the sound of WIRED or WIRELESS MICROPHONE to
create a realistic acoustic ambience. You can adjust the reverb depth by using the ECHO knob.
The depth range is from MIN through MAX. The MIN level produces no effect, while MAX level
produces maximum reverb depth.

5 Does a wireless amplifier need to be installed with a tripod? What is the ideal
height for Amplifier above the ground?
Higher position of a wireless PA will be helpful for signal reception. It can be mounted
on the tripod and above the ear or head of the audience. If the tripod is not allowed on
site, you can also raise it on a table or a flat object while the amplifier leaves the
ground by 1 meter or more.
6 Will wireless amplifier automatically power off once it is fully charged? Do I need
to unplug the power cord?
Yes. Since all CHIAYO amplifiers have an overcharge protection circuit that
automatically power off at full charge and prevent damage to the system.
However, please unplug the power cord after fully charging to ensure the safety.
7 How to charge and maintain the battery of wireless amplifier?
After plugging the power cable of the wireless amplifier into a standard outlet, the
charging LED will glow or flash indicative of charging status. The wireless amplifier
can be charged whether power on or off.
The amplifier's battery has no memory effect and can be charged any time. It is
suggested to charge the battery right after usage to make the battery life longer. If not
to use it for a long period, please charge the battery at least every three months for
lead-acid batteries and six months for lithium batteries.
The battery life is limited and affected by the environment, charging method and
battery efficiency.
8 Is it possible that COACH PRO can work as amplifier only? Can I use only one or
more microphones? How many wireless microphones can be used at most?
COACH PRO can work as amplifier only. Only one microphone can be used on the
amplifier.

Maintenance-free Lead-acid and Lithium batteries
4. Maintenance-free Lead-acid and Lithium batteries
Cautions when using the battery
1. Lead-acid batteries/lithium batteries have no memory effect. Please charge them up immediately after
each use, no matter how much power they left. If the battery is not charged for a long time, it may cause
the battery to be over-discharged and damaged, making it impossible to charge normally.
2. Usage temperature can’t be lower than -10°C nor higher than 50°C.
3. It’s strictly forbidden to let the battery contact with any liquid. Do not immerse the battery in water or get it
wet. After the battery is exposed to water, a decomposition reaction may occur, which may cause battery
self-ignition or even cause an explosion.
4. It is forbidden to use the battery when it has swelled, leaked, or the packaging is damaged.
5. It is forbidden to disassemble the battery in any way or pierce the battery with a sharp object, so as not to
cause the battery to catch fire or even cause an explosion.
6. The liquid inside the battery is highly corrosive. If it leaks, please do not touch it. If the internal liquid
splashes on human skin or eyes, please immediately rinse with clean water for at least 15 minutes before
seeking medical attention.
7. It is forbidden to use wires or other metal objects to short-circuit the positive and negative electrodes of
the battery.
Cautions when charging the battery
1. Lead-acid batteries/lithium batteries have no memory effect. Please charge them up immediately after
each use, no matter how much power they left. If the battery is not charged for a long time, it may cause
the battery to be over-discharged and damaged, making it impossible to charge normally.
2. Please use the power supply specified by CHIAYO for charging.
3. The CHIAYO amplifier has a protection circuit to prevent overcharging. To ensure safety, the charging
time should not exceed 12 hours. Please disconnect the power supply when fully charged.
4. Charging temperature can’t be lower than 0°C nor higher than 40°C.
5. When charging, please place it on the hard ground, such as cement, and there should be no flammable
or combustible materials around. Please pay attention to the charging process to prevent accidents.
6. It will automatically stop charging when fully charged. After the battery is fully charged, it is recommended
to disconnect the amplifier from the power supply.
7. When the power supply is not disconnected and the amplifier is not in use, if the battery is fully charged
and then recharged again soon after, it means that the battery is aging and cannot store power. Please
replace the battery to ensure enough time for operation.
Cautions when storing the battery
1. Lead-acid batteries/lithium batteries have no memory effect. Please charge them up immediately after
each use, no matter how much power they left. If the battery is not charged for a long time, it may cause
the battery to be over-discharged and damaged, making it impossible to charge normally.
2. Lithium batteries will automatically discharge in storage. If they are not charged for a long time, they will
over discharge that causes a decrease in capacity and damage to the batteries that can no longer be
charged normally. It should be fully charged at least once every 6 months.
3. Lead-acid batteries will automatically discharge in storage. If they are not charged for a long time, they
will over discharge that causes a decrease in capacity and damage to the batteries that can no longer be
charged normally. It should be fully charged at least once every 3 months.
4. Storage temperature can’t be lower than -10°C nor higher than 40°C.
Disposing the battery
Be sure to completely discharge the battery before placing it in the designated battery recycling bin.
Batteries contains dangerous chemicals. When disposing of old batteries, be sure to follow the local battery
recycling and disposal regulations, and it is strictly forbidden to put them in a trash can.
