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 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 hot 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.
Level
The main power switch turns the amplifier on.
When the power switch is turned On ("|"
position) the LED lits. After approximately
7 seconds the main power supply voltage will be
turned on internally and the
and
LEDs will illuminate until all the voltage levels are
stable. Then the
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.
ALWAYS TURN THE MAGNETOTHERMIC
SWITCH OFF BEFORE UNPLUGGING THE MAIN
CORD
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.
