About Rotel

Our story began nearly 50 years ago. Over the decades, we have

received hundreds of awards for our products and satisfi ed 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-fi 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 fi 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 fi 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 and later discarded, it is especially important

for a manufacturer to do all it can to engineer products that have a

minimum negative impact on landfi ll sites and water tables.

At Rotel, we are proud to do our part. We have reduced the lead

content in our electronics by using special ROHS solder, while our new

Class D (not digital) amplifi ers are up to fi ve times more effi cient than

our legacy designs and still deliver power and performance. These

products run cool, give minimum wasted energy, are good for the

environment and give better sound too.

Finally, we have printed this brochure on recycled paper stock.

While we understand that these are small fi rst steps, they are still

important ones. And we continue to pursue new methods and

materials for a cleaner and greener manufacturing process.

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

This RMB-1565 power output is quoted as 100 watts for each

channel, when all fi ve channels are operating together at full power.

The RMB-1575 produces 250 watts per channel, also with all fi ve

channels operating at full power.

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 amplifi er’s

power capability.

When comparing specifi cations for different products, you should be

aware that power output is often specifi ed 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 fi gure. The highly regulated

power supplies of the Rotel Class D amplifi ers ensures that they will

produce the full specifi ed power output to one or all channels.

A loudspeaker’s impedance rating indicates the electrical resistance

or load it offers when connected to the amplifi er, 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.

So ideally, the amplifi er should be give double the power into a 4 ohm

load – a rating of 100 watts into an 8 ohm load should become 200

watts into 4 ohms. Using lower impedance speakers makes greater

demands on the amplifi er’s power supply, because it will be drawing

more current and giving off more heat.
