outputs for approximately two seconds when the amplifier is
turned on.
4. It is very important that loudspeaker cables of adequate size
be used in your music system, to ensure that there will be no
power loss or heating. Cable size is specified in Gauge
numbers or AWG (American Wire Gauge). The smaller the
Gauge number, the larger the wire size:
If your loudspeaker cables are 25 feet (7.62m) or less,
use at least 18 Gauge (AWG) wire size or larger.
If your loudspeaker cables are 50 feet (38.1m) or less,
use at least 16 Gauge (AWG) wire size or larger.
If your loudspeaker cables are 100 feet (76.2m) or less,
use at least 14 Gauge (AWG) wire size or larger.
