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 ferrouid-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

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 congurations both directly or via
secondary prexed 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 ofce 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 bafe 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.
Bafe assemble can be hooked onto the back can with care.

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 congurable 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 bafe 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 condence. As with all of Tannoy’s CMS in-ceiling loudspeakers, the CMS 1201DC
