FI-Amp4D
4 channel class D power amplifier, 4 x 50W @ 4Ω with DSP
The Fi-Amp4D is a state of the art 4 channel Class D amplifier providing 50 Watts per channel @ 4Ω. It provides a front panel access volume control allowing zone level adjustments directly from the amplifier.
The amplifier integrates DSP, providing full crossover functions to create factory presets making the amplifier “plug and play”. A user access application allows the connection of a PC via USB to control a 10 bands graphic equalizer for room tuning.
Technology
Class D technology greatly improves efficiency to over 90%. Less power going into heat dissipation, meaning that most power you pay for goes to speakers.
As a result, the amplifier is much smaller in size an lighter, saving precious shelf space. Lower heat dissipation also reduces stress put on each electronic components, extending the amplifier’s lifetime.
USB player and Bluetooth technologies are integrated to make this amplifier a complete control center for your demanding audio needs.
