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. See
the Connecting Power section for more information on voltage requirements.

Although the CS3000H amplifier has R R a a m m p p U U p p
output relay closes, 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 resistance robs amplifier power in two ways: power lost directly to
resistance (I 2 R loss), and by lowering the total load impedance. Also make sure the mode switch is
correctly set for the desired application. See Sections on S S t t e e r r e e o o , P P a a r r a a l l l l e e l l and B B r r i i d d g g e e d d M M o o n n o o operation for
more information.
