PROTECTION

The unit comes with many circuitry protection features
that protecting it and the speakers it's connected to from
harm.
SHORT CIRCUIT: When speakers short circuit, this fea-
ture protects the amplifier by cutting off the output current
to the speakers.
THERMAL: Heat is created during high level output –
especially when operating under bridge mono mode. The
unit comes with a variable speed fan that auto-adjusts the
fan speed depending on the temperature of the machine.
However, if for some reason the unit can not effectively vent
out excessive heat, this feature will protect the unit from
over-heating by shutting the unit down.
OUTPUT DC OFFSET: When a direct current enters the
connection between the power amplifier and speakers, it
will negatively affect the speakers by causing the drivers
and cones to work under stressful conditions. This feature
ensures this does not happen by cutting off the output cur-
rent to the speakers when such a situation occurs.
POWER ON / OFF MUTING: There is a two to three sec-
ond delay before the unit sends out any signal. During this
short delay, the entire system will be muted ensuring no
signal affects your signal.
SUBSONIC: Frequencies below 10Hz contain high level of
energy that can be harmful and stressful to many speakers.
Since the normal human listening range is between 20
Hz and 20 kHz, this unit comes with a feature that helps
filter out any frequency that is below 10 Hz to protect your
speakers.
RF PROTECTION: Radio waves are everywhere. This fea-
ture prevents radio frequency interference from affect your
signal by filtering out signals above 200 kHz. This ensures
that radio program signals do not entering the unit.

AC POWER CONSIDERATIONS

The voltage level of the MAX amplifier will depend on your
region. Ensure that the local voltage levels are identical
by those required by your amplifier before attempting to
connect it to an AC outlet. This is particularly important if
you intend to take the amplifier overseas.
Users are advised that they do not remove the ground pin
on the MAX amplifier's AC connector under any circum-
stances.
As the amount of power that the MAX amplifier consumes
can differ greatly depending on the program material being
amplified, it's important that a stiff supply of AC power is
available for the unit. The more power available to the unit,
the better the output will sound; particularly in low frequen-
cy peaks. If you have more than one amplifier sharing a
single AC outlet, turning them on at the same time should
be avoided at all costs. Turning them on in sequential order
will help prevent tripping any circuit breakers.

INPUT WIRING

For balanced signals, users should use 3-conductor
shielded cable with XLR connectors on either end. For
unbalanced signals, 2-conductor shielded cable with XLR
connectors on either end can be used instead. Balanced
cables should be wired according to Audio Engineering
Society standards.
XLR? The name of this kind of connector is derived from
an X connector from Cannon. These are the large, round
connectors that contain three small pins that are arranged
in a triangular shape.
Hot (+) – Pin 2
Cold (–) – Pin 3
Shield (Gnd) – Pin 1
