Hooking Up Cables to Terminals
The Speaker and Balanced pin screw terminal connectors can accommodate up
to 14 AWG cables. 14 AWG cable is recommended for longer connections (greater
than 20 meters / 66 feet). For shorter lengths you can use 16 or 18 AWG cables. It
is recommended to leave about 150 cm (5 feet) of extra cable at the amplier end to
facilitate positioning and installation of the amplier. Do not use staples, nails or other
metal objects to secure the cables. You will get the best sound quality and least amount
of hum by keeping the cables away from other electrical wires and cables.
Pay attention to connecting the polarity of the amplier correctly with the balanced
audio source and speakers (speakers should be connected RED + with + amplier
terminal, BLACK - with – amplier terminal). Before connecting make sure that your
amplier is switched o. Please refer to your speaker instruction manual for more
information.
NOTE! This amplier accepts only speakers with impedance of 8 Ohms. Connecting
speakers outside this range can damage this amplier or speakers. This may void your
warranty.
