Info Sheet

Rotel’s new custom power ampliers 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.

RKBF-1
Optional cooling fan for rack mount ampliers
application. The RKB-650 is rated 6 x 50 watts RMS @ 8 ohms.
These power ampliers are extremely robust and are able to
increase their output power into 4 ohms (20 Hz-20 kHz, 0.05%
THD).
Each RKB power amplier 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.
