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.

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.

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.

more microphones? How many wireless microphones can be used at most?

receiver, transmitter and MP3 recorder player (DPR-500m) for
STAGE PRO
are
modular products which can be installed optionally according to application and
requirement.
