ROTEL RKB-850 (D)
$0.00Price
The RKB-850 and RKB-D850 are rated at 8 x 50 watts RMS into 8 ohms all channels driven and can double that output into 4 ohms as a result of their sophisticated, efficient Class D design. The amplifiers are rugged and extremely reliable. Yet, Rotel has gone further to maximize long service life, utilizing dual thermostatically controlled fans to exhaust heat away from the output modules and power supply.
Details
Both the RKB-850 and RKB-D850 feature input linking through input A on the rear panel allowing the analog or digital signal on input A to be routed to all three other channels saving time and additional wiring. Analog 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.
