PRECAUTIONS
1. When rst powering-up the amp, keep the amplier Gain
Controls all the way off, in order to block potentially damaging
or annoying sounds caused by defective cables or hookups.
When turning up the Gain, do it gradually, until normal
operation is veried. These precautions are necessary with
all high-power ampliers, since they have enough power to
blow most speakers in abnormal situations
2. Check the AC Voltage before connecting the AC plug.
3. The amplier is protected from surges in power-line voltage
by the fuses. Should your unit ever fail to power-up, rst
unplug the power cord, and then replace the fuse with exact
type and value.
