Make sure the mains voltage is correct and is the same as that printed on the rear of the amplifier.
Damage caused by connecting the amplifier to improper AC voltage is not covered by any warranty.

It is always a good idea to have the gain controls turned down during power-up to prevent speaker
damage if there is a high signal level at the inputs. Whether you buy or make them, use good-quality
connections, input cables and speaker cables, along with good soldering technique, to ensure trouble-
free operation. Most intermittent problems are caused by faulty cables.
Consult the Wire Gauge Chart (below) to determine proper gauges for different load impedances and
cable lengths. Remember that cable impedance robs amplifier power in two ways: power lost directly to
resistance (I2R loss), and by raising the total load impedance.
