LED Indicators:
AC Main connection
Warning: before connecting to mains be sure that the amplifier is set to the correct mains voltage.
The AC Main connection is made via the IEC type connector on the rear panel. The picture below shows the connection to the amplifier. The amplifier is a resistive load for the mains network, minimizing the reactive power and the harmonic distortion on the current. The system allows performance to be maintained even in circumstances of varying the mains voltage. Is important to connect the ground for safety, do not use adapters that disable the ground connection.
Connecting Inputs
Input connections are made via the 3-pin XLR-female on the rear of the amplifier
Connecting Outputs:
Output connectors are made via Neutrik Speakon connectors. Consult the wire gauge chart to find a suitable wire gauge to minimize power and damping factor losses in the speaker cables. The outputs can also work in bridge mode. In normal stereo or linked mono mode, for each channel 1+ of the Speakon connector is the positive output and the 1- pin of the Speakon should be treated as the negative output.Be sure to use balanced inputs on all measurement equipment if you are bench testing
Note: In Bridge Mode the link switch must be switched to "on" and the gain controls of both channels must be set to the same level
