APU150 / APU350 / APU550
Your IQ Series speaker must be used with an APU protection device or another approved
protection device. These include the APU-RS8E rack mount device or an Amina approved
active device (such as Cloud EQ in commercial systems) should be used. Please refer to
the instructions supplied with the APU devices and full warranty information for further
details.
Installation Backboxes
The IQ Series have been designed for optimum sound quality when used in the Amina
BackboxCV We recommend that they are used wherever possible in a cavity type
installation. If our basic fixing block kit is used you may find that the low/mid frequencies
are reproduced less accurately, but any effect will be very much installation specific.
When installed into solid walls or ceilings using the Amina BackboxSW, you may find that
your IQ Series reproduces slightly less low frequency output compared to a BackboxCV
installation. Also, depending on the building construction, there may be significant
mechanical sound transmission into adjacent rooms/properties (see inside front cover).
IQ Series Audio Characteristics
The IQ Series speaker generates sound in a similar way to an acoustic musical instrument.
The speaker’s front face is effectively the “musical” soundboard and the sound waves
generated from it are diffuse and are dispersed over a very wide angle. This means that
loudspeaker positioning is far less critical than with conventional speakers. Additionally,
just like the acoustic musical instrument, the IQ Series has excellent room filling abilities.
The IQ Series is a planar device and this feature is further enhanced when it is flush
mounted into your wall or ceiling. Being planar (or flat) means that the audio’s arrival
time to the listener is the same for all frequencies, i.e. there is very little phase distortion.
Therefore the IQ Series (and other planar devices such as electrostatic loudspeakers) can
reproduce subtle nuances on a recording with incredible accuracy.
In addition to the above characteristics, the radiating surface of an IQ Series is very stiff
and undergoes very small amounts of movement in order to generate high sound pressure
levels. This means that the IQ Series is inherently “fast” making it a highly articulate
loudspeaker.
Wall or Ceiling Placement
The IQ Series are suitable for both wall and ceiling installations. When the most uniform
audio coverage in a room is required, space the speakers evenly in the ceiling. However, if
the room has a height greater than 6m (19’), Amina suggests installing them in the walls at
a height of around 1.8m (6’).
In dedicated listening rooms where IQ Series speakers are used in stereo or multi channel
systems, position them in the walls so that the centre point of an IQ Series speaker is
approximately 1 – 1.8m (3.5 - 6‘) from the floor. This will give excellent results, but don’t
worry, if this is not possible to achieve in your room, the audio characteristics of the IQ
Series make exact positioning according to stereo 5.1 and 7.1 conventions far less critical.
