The RB-1582 MkII is a stereo power amplifier from Rotel, built with an extraordinary damping factor and a strong signal-to-noise figure. The RB-1582 MkII brings Rotel's considered engineering to dedicated stereo power amplification.

Key specs that matter

Input sensitivity is 3mV via XLR or 1.9mV via RCA. Input impedance is 100,000 ohms balanced or 12,000 ohms single-ended. Output power is 200W into 8 ohms, rising to 323W into 4 ohms. Gain is 22.5dBu via XLR or 26.5dBu via RCA. Signal-to-noise ratio is a strong 116dB. Maximum power consumption is 550W, with damping factor at an extraordinary 800 - a remarkable figure indicating exceptional control over loudspeaker cone motion. At 431 x 144 x 407mm and 17.6kg, the RB-1582 MkII represents a substantial power amplifier commitment reflecting Rotel's considered engineering standards.

Sound and use context

Expect exceptionally clean, tightly controlled amplification reflecting the extraordinary 800 damping factor combined with the strong 116dB signal-to-noise figure, consistent with Rotel's broader accomplished engineering philosophy.

Pairing

The extraordinary 800 damping factor suits demanding loudspeaker loads with excellent bass control, and the substantial 323W-into-4-ohms output handles demanding loudspeaker loads with confidence.

Alternatives

Rotel's own RB-1590 offers a considerably more powerful alternative within the same broader power amplifier catalogue.
