The MONO IV is a mono power amplifier from Accustic Arts, a German manufacturer known for serious high-end digital and analogue engineering, built with substantial output and efficient power consumption. The MONO IV brings Accustic Arts' considered engineering to a serious monoblock power amplification format.
Key specs that matter
Input impedance is 20k ohms balanced or 100k ohms single-ended. Output power is a substantial 510W into 8 ohms, rising to 760W into 4 ohms. Gain is 30dBu. Signal-to-noise ratio is 96dB, with total harmonic distortion plus noise at an exceptionally low 0.004% and maximum power consumption at an efficient 120W relative to the substantial output. At 340 x 470 x 440mm and 42kg, the MONO IV represents a serious monoblock commitment.
Sound and use context
Expect substantial power delivery combined with exceptionally clean measured performance reflecting the strong 96dB signal-to-noise and low 0.004% distortion figures, consistent with Accustic Arts' considered German engineering approach.
Pairing
The substantial 510/760W output suits a wide range of loudspeaker sensitivities and impedances, and Accustic Arts' own MONO VI sits above within the same broader monoblock catalogue.
Alternatives
Accustic Arts' own MONO VI sits above this model with considerably greater output, worth comparing directly to find the right Accustic Arts monoblock tier.
