AMR650 / OS165CC in-ceiling speakers
Standard installation would specify AMR650/OS165CC ceiling mounted
speakers which are matched to the Opus 300 system for optimum audio
performance. However, virtually any customer-specified speaker units may
be used.
Where ceiling or wall-mounted speakers are used, care should be taken to
ensure that all building regulations are followed.
When mounting speakers flush to a ceiling or wall, ensure that enough
depth/clearance is available in the respective cavity. A clearance of at least
80mm is necessary when mounting pairs of AMR650/OS165CC speakers.
When deciding upon a ceiling or wall placement, care should be taken to
avoid joists, load bearing beams etc.
Before cutting ceiling loudspeaker holes it is suggested that the area is
tested for clearance by making an L-shaped probe from strong wire (eg a
coat hanger), drilling a small hole in the target area, inserting the probe and
slowly turning. Any obstructions will be immediately obvious, so that the
target area can be moved to a more suitable position.
Also, locate loudspeakers taking into account location of furnishings for
optimal stereo reproduction.
Full details of installation, connection, operation and special features can
be found in the guide that accompanies the speakers.
