The AD-1PA is a stereo power amplifier from Tone Winner, built with substantial output power and a detailed dual-mode power-consumption specification. The AD-1PA brings Tone Winner's considered engineering to dedicated stereo power amplification.

Key specs that matter

Output power is a substantial 300W into 8 ohms. Gain is 29.5dBu. Frequency response spans a wide 10Hz to 100,000Hz within plus-or-minus 3dB. Signal-to-noise ratio exceeds a strong 108dB, with total harmonic distortion plus noise at or under an exceptionally low 0.008% at 100% global feedback. Maximum power consumption spans a detailed dual-range specification of 260-300W or 70-110W depending on operating mode. At 444 x 294 x 449mm and 43.4kg, the AD-1PA represents a substantial power amplifier commitment reflecting Tone Winner's considered engineering standards.

Sound and use context

Expect exceptionally clean amplification reflecting the strong over-108dB signal-to-noise figure and near-immeasurable 0.008% distortion figure, consistent with Tone Winner's broader considered engineering philosophy.

Pairing

The substantial 300W output handles demanding loudspeaker loads with confidence.

Alternatives

Tone Winner's own AD-1PA+ offers an updated version with a somewhat higher RCA signal-to-noise figure within the same broader catalogue.
