1. Introduction
The Tannoy CMS60 TDC –60 / CMS60 TDC -8 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.
The CMS60TDC is best described as a premium quality ‘Ceiling Monitor System’; the heart of
which is the 165mm (6.5”) Tannoy proprietary Dual ConcentricTM transducer. This drive unit,
also used in Tannoy studio monitors, incorporates latest generation design features including
a dual magnet assembly, HF Tulip WaveGuideTM and injection moulded polypropylene LF
cone. The low frequency (LF) and high frequency (HF) sources are coincidentally aligned to a
point source, resulting in a smooth uniform frequency response over a wide area of coverage,
this is unachievable with discrete two-way designs in the vertical plane where massive
cancellations appear off axis at the crossover frequency.
The Tannoy proprietary Dual ConcentricTM transducer 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 THP60 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 TDC –60 / CMS60 TDC -8 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 TDC –8, low impedance only.
2. Unpacking
Every Tannoy CMS60 TDC –60 / CMS60 TDC -8 product has been carefully tested and
inspected before being packaged and leaving the factory to make sure it reaches you in
perfect condition. However, we would ask you to make sure that no damage has occurred in
transit. In the unlikely event of any damage, would you please notify your dealer immediately
and retain the carton and packing materials. Your dealer may ask you to return the damaged
unit for inspection.
The CMS60 TDC –60 / CMS60 TDC -8 is packed in pairs, and any additional optional extras
will be provided in separate packaging. These options include: C Ring, Tile Bridge and Plaster
Ring. The cardboard paint guard should be removed before use.

3. Installation Instructions
3.1 Hole Cut Out
The cutout size required is 305mm (12”)
3.2 Connections
The CMS60 TDC –60 / CMS60 TDC -8 is provided with a plugable European type
connector, which is located on the back of the speaker can, under the wiring cover as shown
in Figure 3a below. This consists of a plug and socket. The plug can be removed from the
socket (Figure 3b)for wiring.
Figure 3a. Figure 3b.
The plug is wired to the amplifier such that the connections are as follows:
Pin 1 is Positive
Pin 2 is Negative
For additional speakers, pin 3 and 4 are in parallel with pins 1 and 2, where:
Pin 3 is Negative
Pin 4 is Positive
Before connecting the speaker, ensure the wiring cover and cable clamp on the back of the
can are open as shown in Figure 3c.Connect the wired plug into the socket.

When the plug has been connected, close the wiring cover as shown in Figure 3d, below:
Place the wires in the recess in the cable clamp. Close the cable clamp as shown in Figure
3e and tighten the screw holding the clamp in order to secure the cables in place.

3.3 Installation
The CMS60 TDC –60 / CMS60 TDC -8 is supplied as a complete product, ready for
installation. An optional C Ring, Tile Bridge and Plaster Ring are available if required. The
CMS60 TDC–60 / CMS60 TDC -8 has been designed for ease of installation.
To install the speaker, connect the speaker as described in the section 3.2. The speaker has
4 tags (Figure f), which hold the speaker in place. Ensure these tags are flat against the can
before installing into the ceiling.
Figure f.
Tags for fastening speaker
Screws for tightening tags

Slide the speaker through the 305mm hole, as shown in figure g, and tighten the outer
screws on the front baffle. Tighten these screws until a secure grip is established as shown in
Figure h.

3.4 Speaker Assembly with C-ring
To spread the weight / pressure of the 4 tags, an optional C-ring is available for the CMS60
TDC –60 / CMS60 TDC -8. To install the speaker in the ceiling, place the C-ring behind the
surface by separating opening of the C-ring and twisting it through the hole. Slide the speaker
assembly through the hole and tighten the tag screws, until a firm grip is achieved,
3.5 Speaker Assembly with Tile Bridge and C-ring
If the speaker requires additional support, an optional Tile-bridge is also available for use in
conjunction with the C-Ring. This is assembled as shown in below. The Tile Bridge is
attached to the C-ring, and the tile bridge supports are placed either on the supporting
framework for the false ceiling or inside the framework, depending on the ceiling grid spacing.
Slide the speaker assembly through the hole and tighten the tag screws, until a firm grip is
achieved.

3.6 Speaker Assembly with Plaster ‘Mud’ Ring
An optional plaster (Mud) ring can be used if a conventional ceiling tile is not being used. The
wings on the plaster ring are attached to the building structure using the holes provided. The
plaster is then applied over the bracket.
4. Polarity Checking
It is most important to check the polarity of the wiring. A simple method of doing this without a
pulse based polarity checker is as follows: Connect two wires to the +ve and -ve terminals of a
PP3 battery. Apply the wire that is connected to the +ve terminal of the battery to the speaker
cable leg which you believe to be connected to the red speaker terminal, and likewise the -ve
leg of the battery to the black speaker terminal.
If you have wired it correctly the LF drive unit will move forward, indicating the wiring is
correct. All that remains now is to connect the +ve speaker lead to the +ve terminal on the
amplifier and the -ve lead to the -ve terminal on the amplifier. If, however, the LF driver moves
backwards, the input connections need to be inverted.
If problems are encountered, inspect the cable wiring in the first instance. It should also be
noted that different amplifier manufacturers utilise different pin configurations and polarity
conventions. If you are using amplifiers from more than one manufacturer, check the polarity
at the amplifiers as well as the loudspeakers.
Important: Connect a safety cable to the rear
of the speaker can.
NOTE: the installation of this product must be
carried out in conformity with
local building codes
and standards. If necessary consult your local
safety standards officer before installing any
product. Alternatively, check any laws or bylaws.
Tannoy will not be held responsible for any
damages caused by the improper installation of
