The Tannoy CMS401 DCe is a full bandwidth ceiling monitor system suited to high-level music and speech reinforcement applications requiring exceptional sonic quality with uncompromised reliability. Specifically designed for fast, simple and cost effective installation in new and existing buildings, the 100mm (4") Dual Concentric™ equipped CMS401 DCe 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. The driver and passive frequency dividing network are mounted in an injection-moulded pod. This, like the ceiling mounting ring in which the pod can be swivelled, is manufactured from UV/weather resistant UL94V-0 ABS material. When mounting the speaker the three self aligning clamps locate the speaker while at the same time locking the pod angle securely. 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. Transformer taps are adjusted via the rotary switch mounted on the rear of the speaker pod: 70V systems: 30W / 15W / 7.5W / 3.75W / OFF & Low Impedance operation; 100V systems: 30W / 15W / 7.5W / OFF & Low Impedance operation. The CMS401 DCe is packaged with tile rails and C-ring for quick & easy installation and simple stocking logistics. A plaster (mud) ring is available as an optional accessory.
