Key specs that matter

Input sensitivity is 2,000mV, with input impedance at 30,000 ohms on both connections, matching the POWERb MONO. Output power is 450W into 8 ohms, rising to 800W into 4 ohms - considerably less than the POWERb MONO's mono-channel figures, reflecting the two-channel configuration. Gain is 30dBu. Signal-to-noise ratio exceeds an exceptional 120dB, matching, with total harmonic distortion plus noise under 0.03% at 100% global feedback, also matching. At 504 x 292 x 521mm and 81kg, the POWERb STEREO shares the POWERb MONO's chassis dimensions and mass exactly.

Sound and use context

Expect exceptionally clean, capable amplification reflecting the exceptional over-120dB signal-to-noise figure combined with the substantial 800W-into-4-ohms output, consistent with Karan Acoustics's broader uncompromising engineering philosophy.
