Mac Audio Apm 4.0

With the APM 4.0, the engineers at Mac Audio introduce a powerful 4-channel amplifier from the APM series. Approved for stable operation at 2 ohms, this powerhouse delivers a robust 150 watts of maximum output power across 4 channels. Alternatively, 2 channels can be powered with 400 watts. High flexibility is ensured not only by the low-level inputs and outputs as well as high-level inputs, but also by variable low-pass and high-pass filters and a switchable bass boost of 6 or 12 dB on channels 3/4. The stylish Mac Audio housing features an operating and overload indicator and also includes protection circuitry against short circuits, DC offset, and overheating.
