1. COOLING FAN - This fan secures cooling for the amplifier. The airflow is from front to rear. The fan speed is
electronically regulated depending on the temperature of the power devices. Do not block these fan grills or
mount the amplifier in an enclosed rack, which could cause the amplifier to overheat.
2.
LOW PASS FILTER – This switch activates the built-in low cut filter. All audio below 30 Hz will be removed
from the output signal.
3.
BALANCED COMBO INPUTS – Connect your mixer to the balanced
XLR or balanced 1/4" input for that channel.
4. OUTPUT MODE SWITCH – The APX 1000 presents three operating
modes:
Stereo Mode
In this mode, CH 1 and CH 2 operate independently (as a normal
stereo amplifier) The CH 1 input signal will be output from the CH 1 output connector, and CH 2 input
signal will be output from the CH 2 output
connector.
Parallel Mono Mode
In this mode, CH 1 input signal will be output from
the output connectors of both
channels.
Bridged Mode
In this mode, CH 1 input signal will be output from
the bridge-mono output connector.
5.
CHANNEL OUTPUTS – Connect your speakers' input
jacks to these outputs.
•
For the binding posts, red is the positive signal
and black is the negative signal.
Please make
sure to respect the speaker polarity when using binding post. Turn off the unit before connecting an
audio signal to the binding post to avoid any electric shock!
•
The SPEAKON outputs are specifically designed to connect to high power speakers. The correct polarity
is secured automatically. They prevent shock hazard and they lock-in securely. Please see the
SPEAKER CONNECTION section to properly and safely connect your speakers.
6.
POWER IN – Connect the cable to a standard wall outlet. Be sure the supplied voltage matches the required
voltage of the amplifier. Do not connect the amplifier to an outlet that does not match the required voltage;
doing so could damage the amplifier.
WARNING!: Do not adjust the
STEREO/MONO BRIDGE SWITCH when the
amplifier is on.
WARNING!: Do not allow any wires of
adjacent terminals to come in contact with
each other. Also, do
not connect either
positive (red) output to chassis ground.
