The Tannoy CMS501 is a full bandwidth; high power and high sensitivity ceiling monitor
system. The design comprises a 130mm (5.00") transducer mounted in a vented, injection
moulded, paintable front baffle manufactured from UV/weather resistant UL94V-0 ABS material.
The point source configuration of the Tannoy ICTTM driver •s mid-bass and tweeter sections
ensures a wide and controlled dispersion for optimum coverage; this while avoiding the massive
loss of energy in the vertical plane, at the crossover frequency, inherent in two-way discrete
designs. The ICTTM (Inductive Coupling Technology) drive unit also addresses the two most
common component failures experienced in background music and sound reinforcement
systems, the tweeter and the crossover reliability. The use of a wireless electromagnetic tweeter
means that no crossover is required in the design; this therefore ensures that an ICTTM unit is
exceptionally reliable and therefore ideal for applications where constant heavy usage is the
norm. This aluminium high frequency dome has a deep drawn skirt that sits on the inside of the
low frequency voice coil in the same magnetic gap. The skirt is like a single shorted turn that is
induced with high frequency information generated by the low frequency voice coil, which is fed a
full bandwidth signal. The mineral loaded polypropylene cone material and nitrile rubber
surround further enhance durability and long-term reliability.
This compact unit is specifically designed for applications requiring the combination of
premium sonic quality for music and speech reinforcement and exceptional reliability.
The CMS501 is equipped with a low insertion loss 30W line transformer easily configurable to the
following settings via front baffle mounted rotary tapping switch:
Two CMS501 model versions and a separate back can are available to satisfy the vast
majority of installation application requirements:
CMS501 BM (Blind Mount) - supplied with an integral back can.
CMS501 PI (Pre-Install) - supplied without a back can.
CMS501 PI Back Can (Pre-wire back can) - use with the CMS 501 PI.
The zinc plated steel back cans have an integrated, recessed termination box. The removable
locking connector has screw terminals for secure wire termination and "loop through" facility.
Strain relief is provided by a clamping mechanism for use with plenum rated cable or conduit.
Spring loaded self-aligning clamps make for quick and easy installation, while all models are also
supplied with two tile support rails and one C-ring included in the package.
A plaster (mud) ring is available as an optional accessory.
