Rotel’s new custom power amplifiers address all of the demands of the professional custom installer: easy rack-mount installation, failsafe design, and set it and forget it operation. They also come with the most important features that all music lovers want: great sound and an affordable price.

This is all possible due to Rotel’s Balanced Design Concept, a design philosophy that emphasizes an exhaustive analysis of every part that goes into our circuits to determine not which one will do, but which one will sound best.

There are three models to cover almost every custom application. The RKB-250 features, 2 x 50 watts RMS @ 8 ohms, the RKB-650 is rated 6 x 50 watts RMS @ 8 ohms, and the RKB-2100 output is 2 x 100 watts @ 8 ohms. These power amplifiers are extremely robust and are able to increase their output power into 4 ohms (20 Hz-20 kHz, 0.05% THD).

Each RKB power amplifier includes front access gain controls for easy settings, a security cover for tamper-proof installations, an IEC detachable power cord, a 12-volt trigger input for remote system operation, and rack mount capability.

With high output power, high thermal stability and short-circuit protection, the RKB Series is the ideal solution to any permanently installed sound system.
