INTRODUCTION 

 

The AQ-10 is the most powerful four channel amplifier within the EM Acoustics range.  It has 
been  designed  to  meet  demands  for  higher  power  and  increased  efficiency,  whilst  still 

maintaining  the  renowned  sonic  qualities  and  unsurpassed  reliability  associated  with  our 
loudspeaker products.

  proprietary  class-D  technology  with  a  dual  feedback  loop  system  gives  exceptional 

transient  response  and  a  resonant  switch  mode  power  supply  with  a  large  reservoir  gives 

extremely high peak power without any “bass sag”. 
 
Newly designed limiters, linked to the output current monitors and power supply, keep mains 

input  and  output  currents  within  a  safe  operating  area  at  all  times,  whilst  maintaining 
transparent sonic performance. 

 
Running cool in even the most difficult conditions, the AQ-10 can deliver over 2500W into 4 

ohms  with  all  channels  driven,  and  a  massive  2  x  7400W  bridged  (4R),  with  outstanding 
distortion and noise figures right up to maximum output. 
 

The amplifier, of course, includes full DC, VHF, thermal and short circuit protection to ensure 
continuous trouble-free service.
