Introduction; Unpacking - Tannoy CMS50 User Manual

1. Introduction

Thank You for purchasing Tannoy CMS50 ICT Ceiling Monitor System.
The Tannoy CMS50 ICT Ceiling Monitor System is suited for high level music and
speech reinforcement
uncompromised reliability. Achieving fast, simple and cost effective installation in new
and existing buildings, this versatile design has addressed the two most common
failures of background music and sound reinforcement systems, which are firstly the
tweeter, and secondly the crossover. With the revolutionary design of the ICT™ drive
unit, neither of the above criteria applies, assuring you years of trouble free use.
ICT™ or Inductive Coupling Technology utilises a wireless electromagnetic tweeter
that does not require a crossover and cannot be burned out from heavy or abusive
use. The 1" aluminium high frequency dome has a deep drawn skirt which sits on the
inside of the low frequency voice coil in the same magnetic gap. The skirt is like a
single shorted turn, which is induced with high frequency information generated by the
low frequency voice coil, which is fed a full bandwidth signal. The ICT™ dome is at the
heart of our 5" ceiling transducer which utilises a moulded plastic cone and nitryl
rubber surround to further enhance it's durability and long term reliability.
The ICT driver is housed in a rugged aluminium ceiling enclosure that has been
optimally tuned to achieve maximum bass response and tonal balance.
The CMS50T ICT houses a Tannoy THP 30 multi-tap transformer for distributed-line
operation. The transformer provides high system sensitivity, a wide bandwidth and
dynamic range, with very low insertion loss. For critical Applications provision has
been made for the CMS50T ICT to accept the THP 60, a 60W multi-tap transformer.
