Tannoy CMS-401-E Brochure

CMS401e

Product Description

The Tannoy CMS401e Ceiling Monitor System is suited to high-level music and speech
reinforcement applications requiring exceptional sonic quality with uncompromised reliability.

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.

The inclusion of a premium quality Tannoy THP 30 multi-tap transformer, for distributed-line
operation, provides high system sensitivity, wide bandwidth and dynamic range; achieved
with very low insertion loss.

Specifically designed for fast, simple and cost effective installation in new and existing
buildings, the CMS401e can be entirely angled towards the listener within the fixed
ceiling-mounting ring. The challenge of difficult speaker placement, in less than perfect room
configurations, is therefore eliminated by being able to discreetly pivot the loudspeaker
towards the desired area of coverage.

Features

• 100mm (4.00") ICT™ Transducer for greater durability

and longevity.
