System Requirements
TCS-C series ceiling loudspeakers are passive loudspeaker systems, and require only one amplifier channel for correct operation, the frequency splitting between the LF driver and the HF driver being accomplished by the internal passive crossover network.
Using Ceiling Loudspeakers with Subwoofers
If subwoofers are required, additional amplifier channels and external electronic crossovers will be required. The Turbosound LMS series digital management systems are recommended for this purpose.

Amplifier Considerations
Turbosound ceiling speakers should be driven by high quality power amplifiers designed for true professional use. Amplifiers should be capable of delivering long term broadband power equal to the loudspeaker’s program power rating at the stated nominal impedance. Always operate your power amplifiers at maximum gain for the best headroom and signal/noise ratio, controlling the overall system volume from the mixing console. The use of under-powered amplifiers must be avoided as heavily clipped signals can cause permanent loudspeaker damage.
In a distributed system the amplifiers must be capable of supplying broadband power equivalent to the sum of the power rating of the loudspeakers (taking into account the individual power taps selected) connected to that particular amplifier channel.
Installation Procedure
1. Cut a hole in the ceiling tile using a circular cutter set the size listed below and pull the wiring through the hole.
TCS-C35T cut-out diameter is 215mm TCS-C50T cut-out diameter is 240mm
2. Connect the wiring to the removable connector. A 4-way Phoenix-style connector is supplied with the loudspeaker. Strip the insulation back by 5mm (3/16”), insert the bare ends of the wire into the connector (do not tin the wire) and screw down the hold-down screw with a small flat blade screwdriver.
3. There are two possible connection strategies, depending on the desired circuit result when a single unit is disconnected for trouble shooting or servicing:
Parallel Input Terminals. This allows the circuit to remain intact whenever a speaker is disconnected. Connect the outgoing pair of wires to the same terminals as the incoming pair of wires.

Loop-through Terminals. All loudspeakers after this unit will be disconnected, helping to isolate problems to a section of the distributed line while leaving the wires connected to the connector.

4. The mounting hardware consists of two tile rails and a ‘C’ plate (these are supplied with the TCS-C35T, and as an optional accessory for the TCS-C50T). Insert the tile rails through the hole in the ceiling tile and align them parallel to each other on either side of the hole, and with the ends positioned over the ceiling T grid. Insert the ‘C’ plate through the hole and snap the tabs onto the tile rails as shown. Position directly over the hole in the ceiling tile and secure with the fixing screws supplied. Note that the provision of multiple fixing holes in the tile rails allows the speaker to be positioned away from the centre of the tile if desired.
5. Plug the connector into the socket in the loudspeaker’s terminal cup. The connector is polarised to avoid the possibility of mis-connection. The terminal cover also acts as the strain relief. Rotate the cover and tighten the retaining screw.
6. Connect the safety tab to a separate support point. Consult construction codes in your region.
7. Insert the speaker into the ceiling and secure the fixing arms. Offer the loudspeaker into the ceiling until the back of the front baffle rim touches the ceiling tile. Turn the attachment screws to tighten the fixing arms. Note that the first 1/4 turn rotates the arm outwards and subsequent turns tighten the tab down onto the ceiling tile. DO NOT OVERTIGHTEN.
8. Adjust the voltage tap selector for desired level. The selector is located on the front baffle, and should be adjusted before fitting the grille. In some installations it may be preferable to leave grilles off until final adjustment of the tap selectors has been completed for all loudspeakers.
9. Apply the logo badge to the grille in the desired location if required, and fit the loudspeaker grille by pressing the grille firmly into place until it is flush with the rim.
Painting before Installation
The loudspeaker’s white finish matches most décor schemes and does not need further finishing. However where interior design requires an alternative colour this can be easily accomplished. The loudspeaker can either be painted before installation, or where the rim needs to be finished at the same time as the ceiling the rim can be painted after locating in the ceiling. The speaker will accept almost any type of emulsion or oil-based paint. Two coats are recommended.

Clean the rim and grille with a light solvent such as white spirit. Do not use gasoline, kerosene, acetone, MEK, paint thinner, harsh detergents or other chemicals, all of which may damage the loudspeaker. After cleaning, apply two coats of paint, using a roller or brush, or by spraying.
Painting the Speaker with the Ceiling
Using the paint shield provided, paint the speaker and remove the shield. To paint the grille, first remove the logo and grille cloth backing. It is advisable to spray the grille to avoid the mesh becoming clogged with paint from a roller or brush, which may impair the sound quality. Replace the grille cloth and the logo.
