Choose speaker cables carefully – please use cables with cores of minimum 
1.5mm

and under 10m in length to prevent power loss. 

 

Check all cables (speaker, signal and mains) for damage, loose terminals or 
potential short circuits on regular occasions. 

 

 

Speaker wires carry high voltages; care should be taken to ensure no bare 

wires can be touched as this may result in electric shock. 

 

The Pulse PLA Series features a dual use locking speaker connector on Output 
A – this allows both amplifier channels to be accessed using one standard 

locking speaker connector. Pins 1+1- are connected to Channel A, pins 2+2- 
are connected to Channel B. 

 

              

 

 

 

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 around 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 front panel, and 

exhausted through the rear panel.  

 

NEVER cover the amplifiers, as they may overheat.  

 

PULSE power amplifiers are designed to fit standard 19” racks, with a 2U 

height and 14.5” depth (not including space for connectors & cables)  

 

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. 

 

Sound reinforcement systems can produce levels of sound that have the 

potential to damage a person’s hearing. Please operate this equipment with 

due care and diligence. If you are in any doubt of the correct operating 

volume for any speaker/amplifier system, please seek advice from a audio 

industry professional of suitable qualification to advise on Sound Levels. We 

also advise the use of good quality decibel meters to ensure sound levels are 

maintained. In the UK the Health & Safety Executive will be able to offer 

advise regarding Noise in the Workplace.
