The MAD A1-70.4 features 4 channels and offers flexibility for different audio system configurations. It delivers 4 x 105W RMS at 2Ω and 4 x 70W RMS at 4Ω, providing stable power to the connected speakers. In bridged mode, it offers 2 x 220W RMS at 4Ω, allowing it to drive more powerful speakers or subwoofers. The damping factor above 130 contributes to better control of the speakers.

The specially designed A-Star cooling frame features an increased heat dissipation surface, helping the amplifier maintain efficient operation even at high volumes. The signal-to-noise ratio above 98dB and THD below 0.5% contribute to clear playback. The high-level input and RCA output make it easy to connect to different sources and expand the system.
