Ampire MBM 720.6 - 6-channel amplifier

New to the MBM series is the MBM720.6 6-channel power amplifier. The speaker inputs are symmetrical and can also be used with high-quality sound systems. We also gave the power amplifier a fixed subsonic filter at 25 Hz. This means that unwanted frequency ranges are no longer amplified.
