Rotel RB-991


The RB-991 provides remarkably lucid sound quality in a visually stunning package.

Each channel delivers 200 watts per channel output over the entire audio bandwidth.

The impressively high damping assures that the RB-991 can lock onto the most difficult loudspeaker to precisely control driver motion for the most detailed sound.

RB991 utilizes two massive power supplies featuring a custom built toroidal transformer followed by individual rectifier arrays and capacitor banks for each channel.

Switchable balanced (XLR) and unbalanced (RCA) inputs provide flexible system interface.

Front panel heat sinks add a strikingly dramatic look and serve a functional purpose by enhancing heat dissipation even in cramped environments with restricted air flow.


Power output: 200 watts per channel into 8Ω (stereo)

Frequency response: 10Hz to 100kHz

Total harmonic distortion: 0.03%

Damping factor: 500

Input sensitivity: 1V

Signal to noise ratio: 120dB

Speaker load impedance: 4Ω to 16Ω

Dimensions: 440 x 127 x 385mm

Weight: 16.7kg
