1. Introduction

Thank you for purchasing this Tannoy product.

The CMS 1201DC is a powerful state-of-the-art large format in-ceiling loudspeaker device conceived, designed

and built to complement Tannoy’s class-leading CMS range. From the pioneers of point source and large format

ceiling speakers the CMS 1201DC is engineered from the ground up with superior full-range performance in mind

to handle demanding distributed sound applications such as ballrooms, shopping malls, sports halls, airports and

other high ceiling installations.

Built around a brand new evolution of the high power handling 12” (300 mm) Dual Concentric™ point source

driver, the CMS 1201DC delivers best-in-class performance for the most even beamwidth and pattern control

over the widest range of frequencies of any large format ceiling speaker. Coupled with exceptional clarity, ultra low

distortion, and high SPLs, Tannoy has again raised the bar to give the absolute cutting edge performance in ceiling

mounted loudspeaker technology.

The new Dual Concentric drive assembly features a treated mid-bass cone and double rolled cambric surround for

high sensitivity, as well as a 34 mm (1.34”) aluminium dome with ferrouid-cooled Neodymium magnet assembly

and a newly designed waveguide for the high frequency unit. These two drivers seamlessly merge into one with the

high frequency mounted in the throat of the mid-bass; coincidentally aligning both transducers to a point source.

The result is a smooth, uniform response over a very controlled 90 degree coverage area – even in the highest

octaves.

2. Unpacking and Visual Checks

Every Tannoy product and accessory is carefully inspected before packing. After unpacking, please inspect your

product to make sure no damage has occurred in transit. In the unlikely event of any damage, would you please

notify your dealer immediately and retain your shipping carton, as your dealer may ask you to return the faulty

unit to him for inspection.

4. Installation Guide

4.1. Back-can

The custom engineered powder coated steel back-can has been designed to cater for all conceivable

installation possibilities making the CMS 1201DC extremely versatile. Internally dampened with 11 mm (0.43”)

OSB2 board, the addition of the back-can provides exceptional low frequency performance.

4.2. Mounted Using Unistrut roof rail system

Steel mounting lugs allow for tting to a Unistrut roof rail system in a variety of congurations both directly or via

secondary prexed cross struts.

Screw at xing point should use a large series washer to help spread the load.

4.3. Flying using Eyebolts

WARNING: As the legal requirements for ying change from country to country, please consult your local safety

standards ofce before installing any product. We also recommend that you thoroughly check any laws and

bylaws prior to commencing work.

The device can also be hung via 4 top-mounted eye bolts. Rear of back can has mounting points for both M10

and 3/8 UNC threaded eyebolts.

4.4. Flying using Screwed Rod

The design also caters for a single point central hang via M10 or 3/8 UNC screwed rod – made easy thanks to

the slotted mounting saddle on the top of the back-can. If required a safety wire can be attached to any of the

M10 ying points.

To t the back can to threaded rod support, rst run a nut 50 mm (2”) up the rod followed by two plain washers

and then a locking nut (Nyloc®). Hook the back can on to the rod between the two plain washers. Once the nut

has cleared the guide slot the top nut can be locked down to secure.

4.5. Fitting the loudspeaker assembly

Mounting of the loudspeaker assembly to the pre-installed back-can is a one man job thanks to the common

sense design approach. One edge of the bafe clips onto the steel box to hold it in place while the installer

secures the assembly in place. Connection is simple via terminal barrier strips inside the can, easily accessible

via 20 mm (0.79“) and 29 mm (1.14”) conduit knockouts on all ve sides of the can. Saving time and manpower

during installation has been a driving factor behind the design of the CMS 1201 system.

Bafe assemble can be hooked onto the back can with care.

5. Wiring and Setting Up

CMS 3.0 Series Operation Manual rev 3.0.0

5. Wiring and Setting Up

The CMS 1201 is available in both a standard low-impedance variant (CMS 1201DC) and a low insertion loss

60 W line transformer-equipped version (CMS 1201DCt) for use on 70 V or 100 V distributed lines. The following

tappings are congurable on the transformer before screwing driver assembly into the back can:

70 V systems: 60 W / 30 W / 15 W / 7.5 W / OFF

100 V systems: 60 W / 30 W / 15 W / OFF

If later adjustment to the level is required the bafe can be hung from the can via a hinged edge, leaving both

hands free to make the required adjustment.

Tannoy’s focus on maintaining the highest standards of continuous product performance and reliability, through

uncompromising quality control of components and manufacturing processes, means you can specify and

install CMS 1201DC with condence. As with all of Tannoy’s CMS in-ceiling loudspeakers, the CMS 1201DC

benets from a 5-year warranty.
