1. Introduction

The Tannoy CMS55 ICT Ceiling Monitor System is suited for high level music
and speech reinforcement applications requiring exceptional sonic quality with
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 can not 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 CMS55 ICT is powered by Tannoy’s THP 30 multi-tap transformer that provides
high system sensitivity, a wide bandwidth and dynamic range, with very low insertion
loss. For critical applications provision has been made for the CMS55 ICT to accept
the THP 60, a 60W multi-tap transformer.

2. Unpacking

Every Tannoy CMS55 ICT and accessory is carefully inspected before packing. After
unpacking, please inspect for any exterior physical damage, and save the carton and
any relevant packaging materials in case the loudspeaker again requires packing and

immediately.
