INSTALLATION GUIDELINES
INSTALLATION GUIDELINES INSTALLATION GUIDELINES
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.
•
PULSE 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 shakeproof washers or threadlock 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.
•
Keep away from magnetic recording media (tape, mini disc, hard drive etc). Power
amplifiers produce an electromagnetic field, which could affect stored files.

1. Read the manual; understand the operation, limitations and safety instructions before using
the product.
2. Use good quality cables of the correct type, in the correct sockets. Speaker cables should
be manufactured from 1.5mm2 or larger cable. Keep speaker lead lengths as short as
possible to minimise signal loss.
3. Listen to your sound; if it’s distorted, reduce gain, volume or both
4. Use adequate amplification and speakers for your needs. Always ensure the output rating
of the amplifier is equal to or more than the RMS ratings of your speakers.
5. Checks the mains supply in the venue; use a mains checker.
6. Ensure your amp, speakers and all cables are free from damage
7. Protect your amp from moisture, smoke/fog machines and glitter cannons
8. Make and check all connections before you switch on
9. Set amp volume to ‘0’ at switch on. Slowly turn up, checking all speakers are working. If
there are problems turn the amp off and resolve them

3. Run amplifiers with the clip or limit lights on constantly
4. Send a clipped or overdriven signal from your mixer or source to the amp
5. Store your amp or speakers in a damp environment
6. Overload mains sockets; Never run more than 3000W of amplifiers, lights or other
electronic equipment from one mains outlet socket.
