JBL | Concert A652 170 Watts 2 Channel Amplifier for Speakers or Subwoofer

• Powerful Class AB amplifier - Class AB amplifier output stage combines the advantages of the Class A amplifier and the Class B amplifier while minimizing the problems of low efficiency and distortion associated with them.
  
  
• Adjustable High-Pass/Low-Pass Crossover Filter - Concert amplifiers have the High-Pass Filter (HPF) and the Low-Pass Filter (LPF), which allow you to adjust the frequency from 40Hz to 400Hz based on your own music taste to deliver the appropriate musical frequencies to speakers.
  
  
• Auto Turn On Facility - When using the High-level signal inputs, the amplifier automatically turns on once a DC offset is detected (>2.5 volts). When using the Line-level signal inputs, the amplifier will also turn on once a +12V signal is detected from the remote turn-on wire.

• Efficient Cooling Design - High performance amplifiers are not only powerful but also compact which depend on overall Efficient Cooling Design.

• Concert Sound and Elegant Looks - JBL Concert amplifiers deliver extraordinary sound experience with elegant industry design.

• Reliable Performance - In order to deliver high quality sound and reliable performance, the high-quality component such as audio capacitors, power MOSFET are selected for Concert amplifiers. Those amplifiers also have to undergo a rigid testing process that would destroy unstable amplifiers. JBL freezes them, bakes them, shakes them, blasts them with ultraviolet light and drives them at full power for days at a time.
