Firstly, check that the specifications of the amplifier are appropriate to the speaker cabinets being operated. Pay particular
attention to the power rating and impedance. Check if the amplifier is switched off before connecting speakers
•
Please note the wiring polarity (+/-). Wires of the same colour must be connected to the same sign of every side i.e. the +
of the amplifier must be connected to the + of the speaker cabinet. If connections are inverted, phase problems will occur.
