AMPIRE 4-Channel Digital Class D Amplifier 24 volts

The further development of our bestseller among the amplifiers, the MBM4.24V-3G, has been perfected in many details in its 3rd generation. The loudspeaker inputs are now balanced and can also be used with high-quality sound systems. We also gave the new 4-channel amp a bandpass including bass level remote for channels 1 & 2. This makes the MBM4.24V-3G even more flexible to use.
