The AJ2504 versatile power amplifier is a convection-cooled power amplifier which makes this unit maintenance-free. The AJ2504 has no fan inside which ensures the amplifier works very silent and it stays dust-free.
The AJ2504 amplifier has 4 individual amplifier channels but can be bridged into 2 stereo channels or even a 2.1 sound system. Use two channels as subwoofer channels and drive your top loudspeakers with the two remaining channels and experience the purely musical power of AJ2504. It is just one of the ways in which you can use this quad amplifier.
The built-in APC Protection Technology allows you to preset the power potential of the amplifier. It constantly analyses incoming music signals and keeps the dynamics alive. An additional ultra-fast peak limiter avoids that the amplifier starts to clip or get distorted.
