You can connect a cable from the SmartAmp or Zone speaker outputs to either of

the +ve (positive) and -ve (negative) pins, and use the other pair to link on to the

next loudspeaker. Note that when using these loudspeakers in low impedance

(not 100 or 70 volt line) you can only connect two loudspeakers per amplier

channel, as the impedance is reduced to 4 Ohms.

When multiple Cuboid 3TX and 5TX are in use, we recommend using 70 volt

taps when using bridged speaker outputs on a Zone, and 70 or 100 Volt as

required with SmartAmp. You can add as many speakers as the total load on the

amplier allows. For example, with the Cuboid 5TX on a 7.5W tap, you can use

up to 33 of them from a single SmartAmp 10.SmartAmp 10 has a maximum

output of 250W when all available power is directed to one channel (no power

will be available on the other channel) - 7.5W x 33 = 247.5W required.

It is perfectly possible to have different loudspeaker on different power tap

settings, to balance volume levels around a room – make sure that the total

power of the circuit does not exceed the capability of the amplier channel

driving that circuit.

For outdoor use, a weatherproof connector cover with cable glands can be

purchased as an accessory to ensure no water ingress to the loudspeaker

terminals.

Be sure to select a gauge of cable with a maximum outside diameter of 6.8mm to

ensure it ts inside the gland, and a minimum OD of 4 mm to ensure a good seal.

Insert the cables to be connected through the gland, then strip to a suitable

length, terminate and tighten the glands, ensuring they clamp onto the outer

insulation of the cable.

Then insert the four screws through the corners of the plate and into the

loudspeaker.

Connecting Cuboid 3, 3TX, 5 and 5TX

Cuboid 3, 3TX, 5 and 5TX loudspeakers are tted with four pin push-in euroblock connectors.
