USER MANUAL TC 1660 Glemm

Audio speaker operating at 70/100V, intended for PA systems.

The high quality of the components used for its construction guarantees an excellent acoustic performance.

The installation of this product must be carried out exclusively by specialized technicians, skilled in electric and audio systems.

In case of wrong installation or connections, the manufacturer doesn't take any responsibility for damages to people or objects.

Refer to the below picture (fig.1) for correct cable connection. Before starting the installation, make sure that the amplifier is turned off. There could be a dangerous voltage on the connection terminals during operations.

Keep the instruction manual for future reference. You can place speaker at wall using small hole on the backside fixing on common nail.

A. 70V / 100V wiring

If you wish to connect the speaker to a constant voltage system, put the common BLACK wire into the "COM" socket of the amplifier, then:

• In 100V systems, connect the WHITE (60W) or BLUE (30W) wire to the "100V" socket of the amplifier.
• In 70V systems, connect BLUE (30W) wire to the "70V" socket of the amplifier.

If you need to connect more than one speaker, after checking the total power, you can connect them to the amplifier with a “parallel” connection.

Remember to consider the correct section of the cables, according to the distance of the speakers from the amplifier.

Consider carefully the power of the speakers and of the amplifier to which they are connected: the total power of the speakers must not exceed the amplifier's power.
