4 channel DSP power amplifier, 4 x 300W @ 8Ω

The FI-AMP300DSP is a state of the art 4 channel Class D amplifier include comprehensive signal processing providing 300 Watts per channel at 8Ω. It provides 4 x front panel access volume control allowing zone level adjustments directly from the Amplifier. The FI-AMP300DSP is designed for use in a wide variety of installations: from a simple setup in a bar/ restaurant or a corporate meeting room to being a part of a larger audio system in a theater. Pairs of channels may be individually configured to run in Stereo, Parallel or Bridged mode


Class D technology greatly improves efficiency to over 90%. Higher efficiency not only means the amplifier will require less power to run, but will dissipate considerably less heat. As a result, the amplifier is much smaller in size, saving precious rack space in an installation. Lower heat dissipation also reduces stress put on each component part in the amplifier and will prolong product life of the amplifier
