Installation Precautions

1. Read all the documentation accompanying your
amplifier before operating.
2. Make absolutely sure the power supply is wired
correctly. This can be done with a commercially
available power supply tester. This especially
applies to three-phase distribution boards where
an incorrectly wired or intermittent neutral line
can cause excessive voltages causing permanent
damage to any 230-110 volt equipment connected
to it. It is good practice to test the power for polarity
and voltage range. Faulty wiring is commonly the
source of many audio difficulties.
3. Always operate the amplifier with the earth
or ground connected. When powered from a
generator, make sure there is a viable earth
connection.
4. Check that the external power wiring is in good
condition. Do not connect to damaged or frayed
wiring.
5. Confirm that the amplifier outputs are correctly
connected before operating. This particularly
applies to multiple speaker arrays here incorrect
wiring can lead to an accidental parallel connection
to another amplifier's output causing damage to
both amplifiers.

6. Do not locate amplifiers close to sources of heat
or moisture.
7. Keep air intake area clear. It is good practice to
clean filter regularly and occasionally check the
amplifier is not clogged with dust. A hot amplifier
rack is a sign of inadequate maintenance or poor
installation.
8. Occasionally check the cooling fans are
functioning. If an amplifier shuts down as a result
of excessive heat, distorts or is not sounding as it
should, check the speaker wiring, power supply,
(too low or too high), fan operation and input gain
structure for non standard setup.
9. Check your amplifier rack is clear of loose cable
ties, screws and stray wirers that can obstruct fans
or allow entry of anything that can cause short
circuit.
10. The amplifier should be returned to Quest Audio
service centre for service by qualifier personnel if
service is required.
11. Output voltages from the QA Series are
potentially high. Use only well insulated quality
speaker cable of suitable gauge. (See section
