Installation guidelines
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.
PQA power amplifiers are designed to fit standard 19 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.

OVERVIEW
It is well-known the PQA series professional amplifier is designed by the
specialist who has full experience and new model equipment. To raise
reliability of the amplifier, PQA series professional amplifier has been
installed with short distance cooling unit,
high-speeding and consistency to increase the life of the power parts.They
all have adopted mature and reliable circuit with SMT technology.
The conventional amplifier applies tunnel-model cooling system, this kind
of system has long distance for heat dissipation,the hot air is distributed
with difficulty, and theradiator is very hot at the top, but too cool at the
bottom, the temperature difference goes between 2 0℃-4 0℃,those system
produces temperature difference easily in the power parts, the electric
current is high in hot parts, which results in its damage and reduces the
using-life and reliability.
PQA series amplifiers has full-protection, including:
Soft start function to prevent wave shock at power-on.
Delay function for prevent shock at switch power on.
DC protection.
Over-electric current protection.
Cut-wave protection.
Over heat protection.
ATTENTION
Never put any parts on the top of the amplifier.
Using fixed power socket that must be has enough capacity to prove power.
Never switch the power on and off continuously at the same time.
Donruction in the air vent of front panel.
Input stereo level can be adjust by own gain mixer, in bridge-model connection,
the adjustment will adjust by CHA channel mixer.
The output connector have 3 kind model, tie-model, phone model and professional
speakon connector for connecting.
When using stereo, bridge, mono function, the connect model must be same than
model switch selected.
When output high-power signal continuously, the amplifier should be has speed-
up in the cooling fan, it may be have low noise produce in this equipment, it is
normally.
The general gain of the amplifier can be adjust by gain knob, the input level
have 0 .7 7V, 1 .4 V, full-power out and fixed 2 6dB gain 3 band should be selected.
Donr vent of rear panel.
When clear-up the cover of the equipment, you must be power off and loose the
power Plug using dry-cloth to clear, never using and solvent that have corrosive
to clear.
If have problem happened, power down immediately, and contact with dealer.

Service
All the products are thoroughly examined and tested
before leaving the factory, and if used correctly will give you
many years of excellent service. However,
if a problem arises, proceed as follows:
(A) contact the retailer from whom the unit was purchased and
describe the symptoms of the fault.
(B) if the retailer cannot help, return the equipment to the
national distributor for your country. Use the original packaging
to protect the product from damage. Include a note with the
equipment stating your name and address, details of the
problems, date code and date and place of purchase.
FAULT PROBLEM SOLUTIONS
No sound
(power
LED off)
AC supply not connected or
switched off
Blown fuse
Check AC connections and switches
Check and replace fuses at plug and IEC
socket. USE ONLY SAME TYPE AND RATING!
NO sound
(Power
LED on)
No input,
or input too low
Level controls set too low
Speakers faulty or
not connected
Check input is connected, and LED
Increase level controls
Check speakers and speaker connections
Hum or
buzz is
audible
Noise from AC supply is being
picked up in the signal path
There is an earth problem
Use good quality, shielded signal cables and
ensure they are kept away from AC power cables
and other AC powered equipment
Use a mains tester to ensure the AC outlet
has a good earth. Power connected equipment(e.g mixer
and amp) from the same AC outlet where possible.
Distortion
is audible
Excessive signal level
somewhere in signal chain.
Damaged or poor quality
cables
Sound cuts
out or is I
ntermittent
Damaged or poor quality
cables or connectors,
connectors not properly
inserted, amp overheating
Use only high quality cables of the appropriate type,
protect them from damage and regularly
check connections.
Use the LED to ensure the AC outlet has a good earth.
Power connected equipment from the same AC outlet
where possible
Check all cables and connections, refer to above
sections regarding distortion and temp warning light
