Important information
The APU-RS8E has been designed specifically to enhance the reliability of your
Evolution Series loudspeakers. It features a high-pass filter and a current sensing fuse
to protect the loudspeaker from being over-driven and potentially damaged. If the
APU-RS8E senses excessive drive current from the system’s amplifier it will
automatically reduce the sound level from the speaker until the amplifier’s volume is
reduced.
It is important to note the following:
• Ensure that the correct internal jumper setting is used on each channel. Failure to do
so could result in speaker damage
• NEVER connect more than one Evolution Series loudspeaker to an output channel
• Be sure that all connections are made in accordance with this guide
• It is not recommended that you use amplifiers with power outputs that are far great-
er than the loudspeaker’s peak power rating
• It is not recommended that you intentionally cause the APU-RS8E to automatically
protect the loudspeakers by deliberately over-driving them
• If you find that the APU-RS8E automatically reduces the audio volume from the
loudspeakers frequently it may suggest that the amplifier being used is too powerful
or that the layer of plaster over the speakers is too thick.
WARNING: DO NOT switch on the amplifier unless both APU-RS8E
and Evolution Series loudspeakers are connected to it. Damage may
occur to the amplifier if it is operated without a loudspeaker connected
to the output of the APU-RS8E.
THE APU-RS8E IS NOT SUITABLE FOR 100V/70V LINE SYSTEMS OR
