2) Connecting the audio sources

The next step is making the signal input connections. Depending of the type connection and output level of the available audio sources they should be plugged into the matching channel/connection.

Before connecting, turn all the channel input and master volume controls on the front panel of the amplifier fully counter clockwise (to their minimum setting) and put the gain control trimmers on the rear panel in a central position. Then connect all the available sources to their corresponding channels and switch on the power of the amplifier and at the connected audio sources the green light around the power button will illuminate after powering on. The buzzer inside will ring three times and then the output protection relay will be switched on (a click will be heard when this occurs) that mean the amplifier is ready.

Apply a signal to the inputs as it will be used in normal operation circumstances and turn the channel input level control up about 50% Slowly raise the master volume control till a certain level until the desired sound level is achieved. Depending of the output level of the connected music sources the input gain might need adjustment. Adjust these trimmers on the rear panel until the desired level is achieved.

For the best signal to noise ratio, the amplifier should run in normal circumstances with the master level control near maximum position and the peak indicator (0 dB) of the VU meter on front should light occasionally (but not frequently during peak levels. If the signal is too loud or distorted use the input level controls to attenuate as necessary to achieve the desired speaker level.

Zone 120BT / Zone 240BT / Zone 360BT

1) Connecting the loudspeakers

The loudspeakers should be connected to the euro terminal block connectors on the back panel of the device. First the decision should be made which kind of loudspeakers will be used between low impedance (4 Ohm) or constant voltage(100V/70V/) depending on the project requirements. It is only possible to use one (either constant voltage or low impedance) of both options at a time

For operating using the low impedance (4 ohm) output any loudspeaker with a minimum impedance load of 4 ohms (that is 4 ohms or greater) can be used.

Example diagram low impedance connections

For operating using constant voltage (100V/70V/...) audio distribution systems, the positive output should be connected to the positive terminal of the loudspeakers, while the negative terminal of the speaker should be connected to the COM (ground) terminal of the amplifier.

ATTENTION

THE TOTAL IMPEDANCE OF ALL CONNECTED SPEAKERS MUST BE GREATER THAN THE RATED IMPEDANCE OF THE AMPLIFIER
