Power amplifiers mono — Audio Analogue ABsolute PA Mono

The ABsolute PA Mono is an accomplished monoblock power amplifier from Audio Analogue, implementing fully balanced discrete circuitry without global feedback, designed to combine high output power with low noise and distortion around a powerful output stage. The ABsolute PA Mono brings Audio Analogue's most accomplished current engineering to a serious, feedback-free monoblock format.

Key specs that matter

Input impedance is a substantial 44,000 ohms balanced. Output power is a substantial 500W into 8 ohms, rising to 800W into 4 ohms. Gain is 25.8dBu. Frequency response spans 20Hz to 20,000Hz within plus-or-minus 3dB. Signal-to-noise ratio is an excellent 118dB, with total harmonic distortion plus noise at 0.1% at 100% global feedback, and damping factor at 45. At 270 x 483 x 445mm and 50kg, the ABsolute PA Mono represents a serious commitment reflecting Audio Analogue's flagship-tier discrete-circuit engineering.

Sound and use context

Expect powerful, low-noise amplification reflecting the excellent 118dB signal-to-noise ratio combined with the fully balanced, feedback-free discrete circuitry, with the substantial 800W-into-4-ohms output delivering flagship-tier dynamic authority.

Pairing

As a monoblock, two units are needed for a stereo pair, and Audio Analogue's own preamplifier catalogue offers natural, brand-coherent pairings.

Alternatives

Audio Analogue's own broader ABsolute series offers related separates alternatives within the same considered feedback-free engineering philosophy.
