Getting Started
Thank you for purchasing the Rotel RB-1090
Stereo Power Amplifier. When used in a high-
quality music or home theater system, your
Rotel amplifier will provide years of musi-
cal enjoyment.
There is nothing understated about the
RB-1090. It is a massive two-channel power
amplifier, capable of providing extremely
high power output in the most demanding
applications. In fact, the limiting factor in
the RB-1090's output levels will often be the
capacity of your home's electrical supply.
Discrete output devices, a massive power
supply with dual toroidal transformers, pre-
mium components, and Rotel's Balanced De-
sign ensure superb sound quality. High cur-
rent capability allows the RB-1090 to drive
difficult speaker loads with ease, including
2 ohm speakers.
Be aware that the RB-1090 is capable of high
power levels, in excess of 400 watts per chan-
nel into 8 ohms and 700 watts into 4 ohms.
Make sure that your speakers can handle
the power of the RB-1090. If in doubt about
your speakers, ask your authorized Rotel
dealer for advice.
The RB-1090 is straightforward in its instal-
lation and operation. If you have experience
with other stereo power amplifiers, you
shouldn't find anything perplexing. Plug in
a pair of high-quality RCA cables from your
preamp into the amplifier inputs, wire up your
speakers, and enjoy.
Alternatively, the RB-1090 provides an op-
tional pair of balanced inputs for use with
preamps or processors that offer these low-
noise XLR-connections. If you choose this op-
tion, you will need to reset a back panel
switch selecting the balanced inputs. Again,
nothing very confusing.
