About the RB993
The Rotel RB-993 is a high-power three-channel solid-state power amplifier designed for home theater systems, ideal for driving front left, center, and front right speakers. It features a high-current power supply with a custom toroidal transformer rated at 1.2 kVA, star-earth grounding, and operates in class-A for low-power levels up to 20W before transitioning to class-AB. The amplifier includes thermal protection, turn-on delay relays, individual channel power supplies with full-wave rectifiers and filter caps, and a 15-amp circuit breaker. It supports 4Ω loads, draws nearly 13 amps at clipping, and is known for quiet operation with low noise and hum, though it generates significant heat. Inputs are balanced XLR and unbalanced RCA per channel, with speaker outputs via binding posts. Power consumption is 550W. Originally priced around 5600 EUR, it is no longer manufactured.
