JBL Concert A652

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 pass 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. Technical data 2-channel class AB car amplifier Rated power RMS output: 65 W x 2 into 4 ohms; 85 W x 2 at 2 ohms; 170 W x 1 at 4 ohm bridge, 75dB Frequency response (-3dB): 10Hz – 45kHz
