JBL Concert A704 4-channel 70W RMS Amplifier

Powerful Class AB amplifier
The 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 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). The amplifier will also turn on once a +12V signal is seen from the remote turn-on wire using the Line-level signal inputs.

Efficient Cooling Design
High-performance amplifiers are powerful and compact, which depend on overall Efficient Cooling Design.

Concert Sound and Elegant Look
JBL Concert amplifiers deliver an extraordinary sound experience with elegant industrial design.

Reliable Performance
High-quality components such as audio capacitors and power MOSFET are selected for Concert amplifiers to deliver high-quality sound and reliable performance. 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.
