Introduction; Unpacking - Tannoy CMS60 ICT–30 User Manual

1. Introduction

The Tannoy CMS60 ICT – 30 / CMS60 ICT - 4 Ceiling Monitor System has been designed for
high-level music and speech reinforcement applications requiring exceptional sonic quality
with uncompromised reliability. The utmost consideration has been given to the installation
procedure to ensure that this product is quick and easy to install.
This versatile design has addressed the two most common component failures experienced in
background music and sound reinforcement system installations, namely the tweeter and the
crossover. Due to the revolutionary design of the ICT™ drive unit, neither of these failures
can occur, assuring you years of trouble free use.
ICT™ or Inductive Coupling Technology utilizes 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 6.5" 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. Also located in this enclosure is
a Tannoy THP30 * multi-tap transformer for distributed-line operation. The transformer
provides high system sensitivity, a wide bandwidth and dynamic range, with very low insertion
loss. The CMS60 ICT – 30 / CMS60 ICT - 4 can also be used in low impedance systems with
this selection being made (along with the transformer tapping options) via a single rotary
switch located on the front baffle for quick and simple commissioning.
*No Transformer with CMS60 ICT – 4, low impedance only.
