10. CHASSIS GROUNDING CONNECTING POINT
To avoid the possibility of ground loop, this unit comes with
chassis grounding point allowing it to be connected to other
units for sharing a common grounding.
11. POWER CORD
This cord draws electricity from power outlet. Near by it,
there is an indicator that tells you what voltage your unit
operates in. Check the AC voltage before connecting the
power plug to the outlet. Make sure the AC requirement
shares the same voltage used in your country (For example,
while some countries use between 110V and 120V, others
use 230V to 240V).
12. RESET SWITCH
Push this button to reset the unit in the unlikely event that
it locks up.

PROTECTION

The unit comes with many circuitry protection features for
preventing it and 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 – es-
pecially when during bridge operation. The unit comes with
variable speed fan that auto-adjusts speed depending on
the temperature of the machine during operation. Howev-
er, for some reason the unit could not effectively vent out
excessive heat, this feature would protect the unit from
over-heating by shutting its power off.
OUTPUT DC OFFSET: When direct current enters to the
connection between the power amplifier and speakers, it
hurts the speakers by causing drivers and cones to work
under stress. This feature prevents this from happening
by cutting off the output current to the speakers when such
situation happens.
POWER ON / OFF MUTING: There is a two to three
second delay before the unit sends out any signal. During
this 2 - 3 seconds, the system will be on mute, no signal
exist this unit.
SUBSONIC: Frequencies below 10Hz contain high level of
energy that can be harmful and stressful for many speakers.
Since normal human listening range from 20Hz to 20KHz,
this unit comes with a feature that helps filter out any fre-
quency that is below 10Hz to prevent speakers from harm.
RF PROTECTION: Radio Frequency is everywhere. This
feature prevents radio frequency interference by filtering out
frequency signal that's above 200KHz. This help prevent
radio program signals from entering this unit.
