About Rotel
Our story began over 60 years ago. Over the decades, we have received
hundreds of awards for our products and satised hundreds of thousands
of people who take their entertainment seriously – like you!
Rotel was founded by a family whose passionate interest in music led them
to manufacture high-delity components of uncompromising quality. Through
the years, that passion has remained undiminished and the family goal of
providing exceptional value for audiophiles and music lovers, regardless
of their budget, is shared by all Rotel employees.
Rotel’s engineers work as a close team, listening to, and ne tuning, each
new product until it reaches their exacting musical standards. They are
free to choose components from around the world in order to make that
product the best they can. You are likely to nd capacitors from the United
Kingdom and Germany, semiconductors from Japan or the United States,
while toroidal power transformers are manufactured in Rotel’s own factory.
We all have concerns about our environment. And, as more and more
electronics are produced it is especially important for a manufacturer to do all
it can to engineer products that have a minimum impact on the environment.
At Rotel, we are proud to do our part. We have reduced the lead content
in our products by using special lead-free ROHS solder and components.
Our engineers continually strive to improve power supply efciency without
compromise to quality. When in standby mode Rotel products use minimal
power to meet global Standby Power Consumption requirements.
The Rotel factory is also doing their part to help the environment through
constant improvements to product assembly methods for a cleaner and
greener manufacturing processes.
All of us at Rotel thank you for buying this product. We are sure it will bring
you many years of enjoyment.
A Word About Watts
The C8 power output is quoted as 70 watts for each channel when all eight
channels are operating together at full power into 4 ohms. The C8+ power
output is quoted as 150 watts for each channel when all eight channels
are operating together at full power into 4 ohms.
Rotel has chosen to specify the power output in this way because, in Rotel’s
experience, it gives the truest value of the receiver or amplier’s power
capability.
When comparing specications for different products, you should be
aware that power output is often specied in other ways, so you may not
be comparing like with like. For example, the power output may be quoted
with only one channel operating, giving a higher maximum gure.
A loudspeaker’s impedance rating indicates the electrical resistance or
load it offers when connected to the amplier, usually 8 ohms or 4 ohms.
The lower the impedance, the more power the speaker will need. In effect,
a 4 ohm speaker will require twice as much power as an 8 ohm speaker.
However, Rotel ampliers are designed to work into any speaker impedance
between 8 and 4 ohms, and with all the channels working up to their full
power. Because the Rotel design is optimized for use with all channels
