The Gas Audio Power MAD A2-85.4 4-channel car amplifier operates in Class A/B and supports high-level input with automatic ATO activation. Balanced differential inputs help reduce noise, while the CLIP function indicates when distortion reaches 1%. It features HPF, BPF and LPF filters with a 12 dB slope, as well as protection circuits against DC, overheating, overload and short circuits.
The heatsink and increased clearance at the side panels allow air to circulate beneath the amplifier.
