JBL Concert A652 2 Channel 500 Watt 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.
