About the RB-985
The Rotel RB-985 is a five-channel, Lucasfilm THX-certified power amplifier intended for home-theater and multichannel audio systems. It delivers 100 watts RMS per channel into 8-ohm loads, with a frequency response of 10 Hz–80 kHz (±0.5 dB), total harmonic distortion below 0.03%, a damping factor of 180, and a signal-to-noise ratio of 115 dB. The amplifier supports speaker loads down to 4 ohms and includes protection circuitry for abnormal operating conditions. It uses RCA inputs along with a DB-25 multichannel input, and its discrete modular circuitry and toroidal-transformer power supply provide substantial current capability. The black chassis measures 440 × 139 × 396 mm and weighs approximately 15.5 kg (34 lb).
