Description of the Rotel RMB-1585 Amplifier:

The Rotel RMB-1585 Amplifier is Rotel’s flagship home theatre amplifier — it provides a solid 200 watts to each of five speakers, like your front left/right/centre channels plus two surrounds.

Weighing in at nearly 80 lbs., this massive amp has two custom-designed toroidal transformers inside, regulated by high-quality, British-made capacitors.

And it’s not just about raw power for volume — it also offers precise control over the stop/start motion of the drivers, for a dynamic, accurate listening experience.

Rotel engineered this amplifier to deliver nuanced sound in a multi-channel surround sound system controlled by a matching Rotel preamp/processor.

There are balanced XLR and unbalanced RCA inputs on the rear panel, plus 5-way binding posts for connecting each speaker. Rack mounting ears are included.

The Rotel RMB-1585 Amplifier, Rotel’s new flagship theatre amplifier, provides both the massive power and sonic sophistication required by the finest home theatre systems.

With five channels, each capable of producing 200 continuous Watts into 8-ohm loads for a full kilowatt of output power, the Rotel RMB-1585 Amplifier is the master of any A/V system, regardless of speaker load or room size.

But it isn’t just pure output power that distinguishes the Rotel RMB-1585 Amplifier. It’s the ability to reproduce both the dynamics of a Hollywood blockbuster and the musical nuances of acoustic instruments that sets it apart.

Where does this balance come from? It’s a direct result of Rotel’s celebrated Balanced Design Concept in which circuit topology and parts selection meld in the pursuit of sonic excellence.

Discrete output devices and a massive power supply also contribute to superb sound quality. The high current capability allows the Rotel RMB-1585 Amplifier to drive the most demanding loudspeakers.

When used in a high-quality music or home theatre system, your Rotel amp will provide years of musical enjoyment.

Driving Your Speakers with Ease:

An oversized factory-built toroidal transformer and high-efficiency capacitors drive an array of high current output transistors ensuring fast transient timing, accurate detail and controlled consistency of low frequency regardless of the loudspeakers load rating or cable run distance.

Maintaining crucial timing and energy while delivering effortless power is a signature trait of this amplifier. The power supply uses special “slit foil” capacitors to provide completely stable power to the output stage.

Slit foil capacitors can charge and discharge extremely quickly, thereby ensuring signal fidelity during orchestral crescendos or repetitive kick-drum impacts, for example.

Critical evaluation of the circuit design and meticulous selection of each acoustic audio component ensures accuracy, power and efficiency all coupled with an unsurpassed build quality ensuring this amplifier proudly wears the Rotel name.

Protection Circuitry:

The Rotel RMB-1585 Amplifier features thermal and over-current protection circuits that protect against potential damage in the event of extreme or faulty operating conditions.

Unlike many designs, these protection circuits are independent of the audio signal and have no impact on sonic performance. Instead. The protection circuits monitor the temperature of the output devices and the current they are handling and shut down the amplifier if operating conditions exceed safe limits. Most likely, you will never see this protection circuitry in action. However, should a faulty condition arise, the amplifier will stop playing and the LED indicator on the front panel will light up.

Built-in Cooling Fan:

The Rotel RMB-1585 Amplifier is equipped with dual cooling fans to help ventilate the internal components.

The rear panel includes a three-position fan speed selection switch including Fan Off, Fan Low Speed and Fan High Speed.

Please select the fan speed that best suits the installation and cooling requirements, considering that a higher-speed fan will provide more cooling.

Trigger ON/OFF Mode Selector:

The Rotel RMB-1585 Amplifier provides the option for manual or automatic power on/off operation. These modes are selectable using a toggle switch on the back panel.

With the switch in the 12V TRIGGER ON position, the amplifier is turned on automatically when a 12V trigger signal is present at the 3.5 mm Jack of TRIGGER IN on the rear panel.

The amplifier will go into standby mode if the 12V signal is not present. The front panel POWER SWITCH overrides this function.

It must be ON for the 12V trigger to work. Turning the switch OFF cuts power to the amplifier, regardless of whether or not a trigger signal is present.
