RB-991
POWER AMPLIFIER
The RB-991 provides remarkably
lucid sound quality in a visually
stunning package. Each channel
delivers 200 watts per channel output
over the entire audio bandwidth. The
impressively high damping assures that
the RB-991 can lock onto the most diffi-
cult loudspeaker to precisely control
driver motion for the most detailed
sound. RB991 utilizes two massive
power supplies featuring a custom built
toriodal transformer followed by indi-
vidual rectifier arrays and capacitor
banks for each channel. Switchable bal-
anced (XLR) and unbalanced (RCA)
inputs provide flexible system interface.
Front panel heat sinks add a strikingly
dramatic look and serve a functional
purpose by enhancing heat dissipation
even in cramped environments with
restricted air flow.
