Rotel RKB-850 Power Amplifier


The RKB-850 and RKB-D850 distribution amplifiers are rugged and extremely reliable. Rotel has maximized long service life, utilizing dual thermostatically controlled fans to exhaust heat away from the output modules and power supply. The RKB-850 is an analogue input only amplifier with four stereo pairs of RCA connectors.

They both feature input linking through input A on the rear panel allowing the analogue signal on input A to be routed to all three other channels saving time and additional wiring. Analogue input A can also be summed to mono, allowing two channels of summed stereo-to-mono output. If input A is set to mono and the link through feature is used, all 8 channels will share the same mono signal – ideal for covering larger areas where normal stereo operation is not desired, for instance landscape audio or commercial applications.


A rear panel RS232 connection allows connection to automation systems to provide control and feedback. The RKB amplifiers also include 4 front panel trim pots which allow easy level adjustment to balance zones.
