JBL Concert amplifiers provide an extraordinary sound experience with an elegant industrial design and an excellent power-to-quality ratio.

  • 4-channel class AB car amplifier.
  • Rated power RMS output: 70 W x 4 into 4 ohms 90 W x 4 into 2 ohms 180 W x 2 into 4 ohm bridge, < 1% THD.
  • Frequency range: (-3dB): 10Hz - 45kHz.

Powerful class AB amplifier
The output stage of a class AB amplifier combines the advantages of a class A amplifier and a class B amplifier, while reducing the problems of low efficiency and distortion associated with them.

Adjustable high/low crossover filter
Concert amplifiers have a high-pass filter (HPF) and a low-pass filter (LPF) that allow you to adjust the frequency between 40 Hz and 400 Hz according to your musical taste to deliver the appropriate musical frequencies to the speakers.

Automatic activation tool
With high-level signal inputs, the amplifier automatically turns on when a DC offset (> 2.5 volts) is detected. With line level signal inputs, the amplifier will also turn on when a +12V signal is detected from the remote trigger wire.

Efficient cooling design
High-performance amplifiers are not only powerful, but also compact, which relies on an overall efficient cooling design.

Concert sound and elegant appearance
JBL Concert amplifiers provide an extraordinary audio experience with an elegant industrial design.

Reliable performance
In order to ensure high-quality sound and reliable operation, high-quality components such as audio capacitors, power MOSFETs are selected for concert amplifiers. These amps also have to go through a rigorous testing process to weed out unstable amps. JBL freezes them, bakes them, shakes them, illuminates them with ultraviolet light and drives them at full power for several days.
