USE

SWITCH ON/OFF

The main power switch turns the amplifier on.
When the power switch is turned On ("|" position) the
PROTECTION LED illuminates. After approximately 7
seconds the main power supply voltage will be turned on
internally and the ON LEDs will illuminate. Then the
PROTECTION LED will go out and the amplifier will be ready
to be used.
To turn the amplifier off push the power switch ("0"
position). At that moment the main power supply voltage
and the secondary power supply voltage will turn off
internally.
Switch your sound system on from back to front. Thus,
switch on the amplifiers last on your sound system. Switch
sound sources (CDs, turntables) first, then your mixer, then
your processors and crossovers and finally the amplifiers. If
you have more than one amplifier, switch them on
sequentially, one at a time or use a sequencer.
Follow the reverse order when switching off, and switch off
the amplifiers before any other element on your sound
system.
CLIP LED
The clip LED should never be on continuously. This will
distort the signal and may damage the speakers. In fact,
severe clipping is an easy way of burning a speaker's voice
coil.
The amplifiers feature an automatic limiting system that
impedes prolonged saturation, but the dynamic nature of
music signals stops it from being a brick wall protection.
Thus at most, the clip light could be lit occasionally.
LEVEL CONTROLS
The LEVEL rotary potentiometer is used for changing the
input gain. Although related to output power, it is not a
direct representation of it. Thus, we can have maximum
output power with the gain at mid position. Similarly, we
may have the gain controls at maximum and not have
maximum output if our source signal is not strong enough.
One way to use the volume controls is to set them such
that when the mixer's faders are at their maximum level,
we are just below clipping level on the amplifier or clipping
very occasionally.
