Concert sound and elegant design

Powerful Class AB Amplifier
Class AB amplifier output stage combines the advantages of the Class A amplifier and the Class B amplifier while minimizing low efficiency and distortion.

Adjustable High-Pass/Low-Pass Crossover Filter
Concert amps feature the High-Pass Filter (HPF) and the Low-Pass Filter (LPF), which allow you to adjust the frequency from 40 Hz to 400 Hz based on your own musical taste to deliver the correct music frequencies to speakers.

Auto power on feature
When using the high level signal inputs, the amplifier will automatically turn on when a DC offset is detected (>2.5 volts). When using the line level signal inputs, the amplifier will also turn on when a +12V signal is detected from the external enable wire.

Efficient Cooling Design
The high-performance amplifiers are not only powerful but also compact and feature an efficient cooling design.

Concert sound and elegant design
JBL Concert amplifiers deliver an extraordinary sound experience and have an elegant industrial design.

Reliable performance
To deliver high-quality sound and reliable performance, the Concert amplifiers use high-quality components such as audio capacitors and power MOSFET. The amplifiers also have to undergo a rigorous testing process that unstable amplifiers would not survive. JBL freezes them, bakes them, shakes them, exposes them to ultraviolet light and tests them at full power for days.
