About Rotel

Our story began over 60 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 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 efficiency without compromising to quality. When in standby mode Rotel products use minimal power to meet global Standby Power Consumption requirements.
The Rotel factory is also doing its part to help the environment through constant improvements to product assembly methods for 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.

Getting Started

Thank you for purchasing the Rotel DT-6000 DAC (Digital to Analog Converter) Transport. When used in a high-quality music or home theater system, your Rotel product will provide years of musical enjoyment.
The DT-6000 is a full-featured, high-performance component. All aspects of the design have been optimized to retain the full dynamic range and subtle nuances of your music. The DT-6000 has a highly regulated power supply incorporating a Rotel custom-designed toroidal power transformer and custom-made slit foil capacitors. This low impedance power supply has ample power reserves, which enables the DT-6000 to easily reproduce the most demanding audio signals. This type of design is more expensive to manufacture, but it is better for the music.
The printed circuit boards (PCB) are designed with Symmetrical Circuit Traces. This insures that the precise timing of the music is maintained and faithfully recreated. The DT-6000 circuitry uses metal film resistors and polystyrene or polypropylene capacitors in important signal paths. All aspects of this design have been examined to ensure the most faithful music reproduction. The main functions of the DT-6000 are easy to install and use. If you have experience with other stereo systems, you shouldn’t find anything perplexing. Simply plug in the associated components and enjoy.

A Few Precautions
WARNING: To avoid potential damage to your system, turn off ALL the components in the system when connecting or disconnecting the loudspeakers or any associated components. Do not turn the system components back on until you are sure all the connections are correct and secure.
Please read this manual carefully. In addition to installation and operating instructions, it provides valuable information on various unit system configurations as well as general information that will help you get optimum performance from your system. Please contact your authorized Rotel dealer for answers to any questions you might have. In addition, all of us at Rotel welcome your questions and comments.
Save the shipping carton and all enclosed packing material for future use. Shipping or moving the unit in anything other than the original packing material may result in severe damage to your unit.
If included in the box please complete the owner’s registration card or register online. Also, be sure to keep the original sales receipt. It is your best record of the date of purchase, which you will need in the event warranty service is required.
Placement
Like all audio components that handle low-level signals, this unit can be affected by its environment. Also, avoid routing audio signal cables near power cords. This will minimize the chance it will pick up hum or interference.
Remember the weight of the unit when you select an installation location. Make sure that the shelf or cabinet can support it. We recommend installing the unit in furniture designed to house audio components. Such furniture is designed to reduce or suppress vibration which can adversely affect sound quality. Ask your authorized Rotel dealer for advice about component furniture and proper installation of audio components.
Cables
Be sure to keep the power cords, digital signal cables, and analog audio signal cables in your installation away from each other. This will minimize the chance of the analog audio signal cables picking up noise or interference from the power cords or digital cables. Using only high-quality, shielded cables will also help to prevent noise or interference from degrading the sound quality of your system. If you have any questions see your authorized Rotel dealer for advice about the best cable to use with your system.
The RR-D150 Remote Control
Some functions can be done with either the front panel controls or the supplied RR-D150 remote control. When these operations are described, the square call-out numbers refer to the main unit, while the encircled letters refer to the remote control.
LIGHT Button L
Push the LIGHT Button L to turn on the backlight on the remote control. This
light can be used to easily see the buttons in a dimly lit room. The backlight will automatically turn off after 10 seconds.
