REAR PANEL DESCRIPTION
7. FAN
These two variable speed fans automatically maintain safe in
-
ternal temperature. Keep the front and rear vents clear to allow
full airflow. Hot air will be drawn out the
back of the amplifier, so
it does not stay in the rack, and make sure plenty of cool air can
enter the rack.
8. RESET BREAKER
With rated loads and output levels, the breaker should only shut
down the amplifier in rare instances of catastrophic failure. The
circuit breaker can also shut down the amplifier in cases where
extremely low-impedance loads and high output levels result in
a current draw that exceeds its rating.This feature is not included
on the XP600.
9. POWER CORD
All units are shipped with an appropriate plug and cord for the
required AC voltage. This product is equipped with a 3-wire
grounding type plug. This is a safety feature and should not be
defeated. Check the AC voltage before connecting the plug.
10. CHASSIS GROUNDING CONNECTING POINT
Please refer to your local safety code for proper grounding.
11. OUTPUT CONNECTORS
A pair of versatile binding posts and Speakon connectors are
provided for output connection to each channel. Loudspeakers
can be easily connected using banana plugs, spade lugs, bare
wires or Speakon connector. Spade lugs and bare wires should
both be screwed down tightly to avoid a short circuit. The Spea
-
kon connector for channel 1 includes channel 1, channel 2 and
bridged mono pin connecting points. A pin out information could
be foundbeside the Speakon connector.
12. INPUT CONNECTORS
The power amplifier offers XLR and TRS input connectors for
your connecting convenience.
13. GROUNDING - FLOATING SWITCH
This switch allows the circuit and chassis grounding to be sepa
-
rated in case of a grounding conflict. In normal use, the switch
should be in the grounding on position. Lifting the grounding
(to what is called the floating position) may resolve the ground
conflict, but it means that circuit grounding depends on other con-
nected equipment. Deficiencies in other components’ grounding
will affect the sound quality and cause a grounding loop hum.
For the best combination of safety and performance, it is highly
recommended to set the switch at the “grounding on” position.
14. LIMITER ON/OFF
This switch allows you to route the peak limiter circuit to the input
signal. This function will reduce distortion and protect speakers.
15. HPF
This switch can activate a 30Hz or 50Hz high pass filter, which
will roll off signals below either 30 Hz or 50 Hz. This improves sub
bass performance by limiting sub bass cone motion. It will make
more power available for the speakers’ rated frequency range.
16. PARALLEL / STEREO / BRIDGE MONO SWITCH
Turn off the power before changing the operation mode. In ste
-
reo operation, each channel of the amplifier runs independently
with its own signal and speakers. When the switch is set to the
parallel mode, the input of CH2 is paralleled with that of CH1.
Then, CH1 and CH2 can drive their own speakers independently,
but they will have the same source, that of CH1. In bridge mono
operation, both channels can be configured to drive a single
load with a single signal at twice the power. Use the following
procedure to ensure the systems safety when switching from
one mode to another:
1. Turn off the power of the amplifier
2. Put one speaker, of not less than 4 ohms impedance, across
the red (+) output terminals of the amplifier.
3. Ensure that there is only one input signal connected to CH1.
4. Switch the amplifier to bridge mono.
5. Turn the gain controls of CH1 and CH2 to the extreme left and
then turn on the amplifier.
6. Verify operation at low gain, and then turn up the CH1 gain
to increase power to a desired level.
