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.
