The Tannoy CMS501 is a full bandwidth; high power and high sensitivity ceiling monitor system; a compact unit that is specifically designed for applications requiring the combination of premium sonic quality for music and speech reinforcement and exceptional reliability.
The design comprises a 130mm (5.00î) ICTô transducer mounted in a vented, injection moulded, paintable front baffle manufactured from UV/weather resistant UL94V-0 ABS material. 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.
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:
70V systems: 30W / 15W / 7.5W / 3.75W / OFF & low Impedance operation
100V systems: 30W / 15W / 7.5W / OFF & low Impedance operation
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 CMS501 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.
