Amina APU350 is a high-pass filter protection unit designed specifically for Amina Evolution Series loudspeakers. Its main purpose is to protect your loudspeaker from over-driving and potential damage. It features a high pass filter and a current sensing fuse that will automatically reduce the sound level from the speaker if it senses excessive current from your amplifier until the volume is reduced to a safe level. The APU350 can be used with any Evolution Series loudspeaker model AIW350E or AIW350E/S200. It's easy to install, connect, and is virtually maintenance-free.

High Pass Filter Protection Unit
User Guide
V1.1 August 2013
APU150/350/550
These protection units have been designed specifically to enhance the reliability of
your Evolution Series loudspeaker. They feature a high pass filter and a current sensing
fuse to protect the loudspeaker from being over-driven and potentially damaged. If the
protection unit senses excessive drive current from your amplifier, it will automatically
reduce the sound level from the speaker until the amplifier volume is reduced to a safe
level.
Please read this document carefully before operating your
loudspeaker and protection unit.
Ensure that the correct model APU is used with the loudspeaker. Failure to do so may
result in speaker damage. See the label on the underside of the APU for model
designation (see next page).
NEVER connect more than one loudspeaker to each output channel.
Be sure that all connections are made in accordance with this guide.
It is not recommended you use amplifiers with power outputs greater than the peak
power rating of the loudspeaker.
Do not intentionally cause the APU to go into protection mode by deliberately
over-driving the loudspeaker.
If your APU automatically reduces the audio volume from the loudspeaker frequently, it
may suggest the amplifier is too powerful or the layer of plaster applied to the Evolution
Series loudspeaker is too thick. In either case please consult with your dealer or Amina
Technologies Ltd.
Install this product in a cool, dry and clean place - away from direct sunlight, heat
sources, vibration, dust and moisture.
Do not expose this unit to sudden temperature changes or locate it in an environment
with high humidity. This is to prevent condensation forming inside which may cause
damage to the unit and possibly other devices connected to it.
Do not clean this unit with chemical solvents as this may damage the finish. Use a
clean, dry or damp cloth.

The APU150, APU350 and APU550 are designed to be free-standing or permanently
fixed to a suitable structure using the two mounting holes.
They do not require ventilation and therefore their installation position is not critical.
However, the product should ALWAYS be installed in a dry environment that will not
exceed 35 degrees Centigrade (95 degrees Fahrenheit).
Do not place equipment on top of the APU.
Where possible, do not position the APU adjacent to mains power cables.
Speaker model compatibility
Only use the APU model with the Evolution Series speaker it is designed for.
