The M27 is a seven-channel power amplifier that supplies at least 180 W of continuous power to each channel into both 8 ohm and 4 ohm loads, measured across 20 Hz to 20 kHz with all channels driven. Distortion is held to 0.005% or less, and the frequency response is flat to within ±0.1 dB across the audio band.
Its inputs are balanced with a 47 kilohm impedance and need 1.3 V to reach rated power. IHF dynamic power is 320 W into 8 ohms, 700 W into 4 ohms and 650 W into 2 ohms. The amplifier switches itself to standby after up to 30 minutes without an input signal, and standby draw is below 0.5 W. A white paper on the HybridDigital technology is listed among the downloads.
The chassis measures 435 x 156 x 380 mm and weighs 14.1 kg. The maker lists a data sheet and manuals in nine languages for it, including English, German, French, Spanish, Italian, Dutch, Swedish, Russian and Chinese.
