RMB-1512 Twelve Channel Power Ampliﬁer

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

minimum negative impact on landﬁll 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) ampliﬁers are up to ﬁve times more efﬁcient 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 ﬁrst 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

The RMB-1512 power output is quoted as 100 watts for each channel,

when all twelve channels are operating together 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 ampliﬁer’s

power capability.

When comparing speciﬁcations for different products, you should be

aware that power output is often speciﬁed 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 maximun ﬁgure. the highly regulated power

supplies of the Rotel Classe D ampliﬁers ensures that they will produce

the full spciﬁed power output to one or all channels.

A loudspeaker’s impendance rating indicates the electrical resistance

or load it offers when connected to the ampliﬁer, usaally 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 ampliﬁer 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 emands on the ampliﬁer’s power supply, because it will be

drawingmore current and giving off more heat.

However, Rotel ampliﬁers 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 operating together, Rotel is able to specify the true

power output for all channels.

This can be important for your enjoyment, too. When watching

movies, it’s nice to have the ampliﬁer able to reproduce full power into

all the channels at the same time, especially in the case of a volcano

exploding!.

About Rotel

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

received hundreds of awards for our products and satisﬁed 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-ﬁdelity 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 ﬁne 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 ﬁnd 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
