Rotel RKB-850 (unpacking unit)
Music everywhere with 8 x 50 watts – that’s what the rack-mountable amplifier RKB-850 is made for.
Robust and reliable
Rotel has been designing and manufacturing award-winning power amplifiers for over 50 years. This considerable expertise has now been channelled into a new generation of rackmount custom installation amplifiers that are sure to set a benchmark for performance, reliability and ease of installation.
The RKB-850 features 8 x 50 watts into 8 ohms on all channels and can double the output into 4 ohms thanks to its advanced and efficient Class-D design. The amplifier is rugged and extremely reliable, but Rotel has gone one step further to maximize its life. They used two thermostatically controlled fans to dissipate heat away from the output modules and power supply.
Among the many user-friendly features of the RKB-850 is the link function for inputs. Input signals can be taken from any “higher” input channel – so B can take signals from A, C can take signals from B, and D can take signals from C. You can create four individual stereo zones, two dual zones or three single and one individual zone. In other words, two Sonos connections (for example) can be split between kitchen and yard (area A+B) and bedroom and bathroom (C+D).
Other features include input signal detection, buffered link output, a sum-to-mono function; an RS232 connection on the rear panel that allows automation systems to be connected for full control and feedback; and four front panel trim potentiometers for easy range adjustment.
