Installing Your Amplifier:  Mechanical Considerations 

 

To ensure that this equipment performs to specification, it should be mounted in a suitable 
rack or enclosure as described below. Like all high power amplifiers, it should be kept away 

from other equipment which is sensitive to magnetic fields. Also, this amplifier may suffer a 
substantial reduction in performance if it is subjected to, or mounted close to equipment 
which radiates high RF fields. 

 
Warning: To prevent injury, this apparatus must be securely attached to the rack in 

accordance with the installation instructions 
 
When mounting the amplifier in a rack or enclosure: 

 

Be aware that… 
 

THE FRONT PANEL IS NOT CAPABLE OF SUPPORTING THE UNIT ON ITS OWN. 

Make sure that the rear of the unit is adequately supported. The brackets which are supplied 
fit standard 19 inch (483mm) rack mounting systems.  
  

ENSURE THERE IS ADEQUATE VENTILATION.  
The cooling fans suck cool air in through the front and blow hot air out at the rear of the unit 

through the ventilating grills. The front and rear of the amplifier should have free exposure to 
the air (i.e. in a rack leave the front & rear doors off), with 2cm air gap at the sides.   
 

IF AIR IS NOT ALLOWED TO ESCAPE FROM THE REAR, OVER-HEATING WILL OCCUR.  
Take care when mounting other equipment in the same rack. 

 
Make sure that the rack unit has a separate earth connection (technical earth). 
 

Please also see the notes regarding maintenance on page 17. 
 

 
Installing Your Amplifier:  RF Emissions 

 
The high frequency resonant converters in the AQ-10 have been designed to have very low 
radio frequency (RF) emissions; however even these low level emissions can cause 

interference with other equipment.  
 

In order for this to be minimised, the amplifier should be mounted in a metal rack enclosure, 
which should have a separate (technical) Earth. Alternatively a separate earth should be 
attached to the amplifier at the rear rack mounting bracket.
