13. Output Mode Selector Switch
Each Channel features balanced XLR and 1/4" jack sockets wired in parallel. The Balanced
signals are less sensitive to hum noise generated by AC.
The stereo power amplifier presents two operating modes:
- Stereo Mode
In this mode, channel A and channel B operate independently (as a normal stereo amplifier). The
Channel A input signal will be output from the channel A output connector,and channel B input
signal will be output from the channel B output connector.
- Parallel Mono Mode
In this mode, channel A input signal will be output from the output connectors of both channels.
12.LIMITER Switch
If a very high level signal is driven into the amplifier, the output signal will "CLIP", that is the peaks
of the waveform will be flattered. The Clip Limiter circuit automatically reduces the gain to prevent
the overdrive. You can switch the Clip Limiter circuit ON and OFF via the (11) switch on the rear
panel of your LA series. If you use full range speakers, the Clip Limiter circuit will reduce the high
frequency distortion and it will also protect the high frequency drivers. However, some Users
prefer to switch the Limiter OFF to get more punch from Kick Drums and other sounds in the low
frequencies area.

- Bridged Mode
In this mode, channel A input signal will be output from the bridge-mono output Connector.
This fan secures enough cooling for your PEXA3000,PEXA5000 amplifier.
SPEAKON connectors are specifically designed to connect high power speakers. The correct
polarity is secured automatically, they prevent shock hazard and they lock-in securely.
Please make sure to respect the speaker polarity when using binding post.
Caution:turn off the unit before connecting an audio signal to the binding post to avoid any electric
shock!
Please make sure that your local voltage matches the voltage indicated on the unit.
Signal Ground lift switch is used to lift the balanced input connectors'ground/shield from the
amplifier's ground. When the signal ground lifted, the sound source disconnects from the
amplifier's ground preventing ground loops which can generate hum and noise. See the signal
ground lift switch instructions for more detail.
The power amplifier must be connected only with the attached three-wire safety power cord with
protective conductor (nonfused earthed conductor).
This amplifier is made for use with te mains voltage labelled on the back of the amplifier only.
Check the label on the back panel of the amplifier for the appropriate voltage. Make sure the
voltage of your mains outlet is correct. The power voltage is factory set as labelled on the back
panel and cannot be change afterwards. Damage caused by connecting the amplifier to
Improper AC voltage voids the warranty.
Allows selection of 0.775V, 1.0V or 1.40V sensitivity.
This fan secures enough cooling for your PEXA8000 amplifier. The airflow is front-to-rear.The fan
speed is electronically regulated depending on the temperature of the power devices.
*DO not use these amplifiers in damp or high humidity environments. Do not use outdoors or
anywhere where liquids could fall or splash onto the amplifier.
*Ensure the amp is adequately ventilated, with free airflow to the front and rear panels. Keep
away from other heat sources. If the amps are mounted in a rack with other amps, ensure there is
adequate cool air flow front and rear. Note that air is drawn in through the back panel, and
exhausted through the front panel.
*Never cover the amplifiers, as they may overheat.
*PYLE PRO power amplifiers are designed to fit standard 19U racks, with a 2U height and 17
depth. We recommend the use of rear rack supports, especially if the rack is to be mobile. Use
shake proof washers or thread lock adhesive to prevent mounting bolts becoming loose in transit.
*Ensure that the AC power supply is correct for your amplifier. The required AC supply is stated
on the rear panel next to the AC power input.
*Ensure that you use the correct type of mains lead for your equipment and country. This must be
free from damage and easily accessible during use.
