A WORD FROM AII OF US AT ROTEL

Thank you for purchasing our RDP 980 Digital to Analog Converter. We have been designing and manufacturing high quality, high performance audio electronics for more than 30 years. This Digital to Analog Converter will provide accurate reproduction of the digital signal and is a natural extension of our love for music. Our passion for good sound and our love of music is well known. We believe that the music played through the RDP 980 and a companion digital source component, such as the Rotel RDD 980, will be a source of enjoyment to you for many years to come.

Rotel is committed to making quality products to enhance your life. We have designed and manufactured this DAC to be durable, easy to use and to exactly replicate the original digital signal while converting it to an analog signal. Please read the owners manual to ensure that the RDP 980 is properly installed and able to offer optimum performance. We appreciate being a part of your life.

FEATURES OF THE RDP 980 DIGITAL TO ANALOG CONVERTER

Careful listening tests have shown that low jitter enhances the sound quality and the enjoyment of the music played through a digital system. We have incorporated recent design and manufacturing techniques to ensure the lowest possible distortion and jitter in this D to A Converter. We have utilized a 1 bit 64 x oversampling Delta Sigma ( ) digital to analog conversion chip including an 8 x oversampling digital filter. We have chosen this combination for its excellent sonic and measured performance. We include a 5th order switched capacitor filter, to minimize didital jitter, and then a 2nd order filter after the 8 x oversampling digital filter to eliminate spurious noise. The output stage is implemented with a low impedance buffer amplifier that includes a 2nd order Butterworth filter, to further reduce spurious high frequency noise. RDP 980 will provide accurate and musical reproduction of the digital information on your CDs or other digital source information.

By separating the DAC from the source component it is possible to optimize the design of both. The result is maximum performance and sound quality. Because the DAC and the source component have separate power supplies, there is no interaction between a mechanical assembly's power requirements and the audio circuits need for a clean, stable and ripple free power supply.

The multiple power regulation stages in the power supply of RDP 980 ensure each critical stage has noise free, stable power for operation. The printed circuit board layout (PCB), the PCB material, the star earth ground patterns and the exact part choices made during design and fine tuning (in the UK) have all been made for one reason only, to provide you with the finest possible Digital to Analog Converter at a reasonable price.

INSTALLATION OF THE RDP 980

Please place the unit on a DRY, level surface away from direct sunlight. Avoid placing objects on top of the RDP 980. Do not allow water to fall into the RDP 980 as this could damage the circuitry or drive components. Avoid installing the DAC in a location where excessive heat, humidity, vibration or moisture will be a problem.

We recommend installing the RDP 980 in furniture designed to house audio components. This will allow the RDP 980 to be on its own shelf, not stacked on another component or with something stacked on it. This will minimize potential interference with other components in your system, such as your tuner or amplifier. Component furniture has the added benefit of reducing

or suppressing vibration and all audio components will provide improved sound when free from vibration.

Component furniture will improve the looks of many system installations and provide adequate ventilation for amplifiers and isolation for other components. It is also easier to dress the wires to reduce interference between sensitive audio cables, speaker cables and power cords for components. Ask your ROTELhi fi Authorized Dealer for advice about component furniture and proper installation of audio components.

ELECTRICAL REQUIREMENTS

This DAC is designed to work on AC voltage and the correct voltage is displayed on the Back Panel. Do not attempt to operate the RDP 980 on incorrect voltage as this will damage the circuitry and void your warranty. If you are in doubt about the correct voltage we suggest that you read the label on the back panel, the label on the packing carton or consult your ROTELhi fi Authorized Dealer for confirmation of the correct voltage.

Connect the Power Cord to your wall socket for AC power. When you wish to disconnect the power cord from the wall, always hold the plug firmly and then pull it out of the wall socket. Do not unplug the power cord from the wall by pulling the cord only. This may damage the power cord and create a hazardous condition. We recommend that the RDP 980 be connected to the mains' wall socket or an AC power line filter, not an extension cord.

If you wish to clean the cabinet on the RDP 980 we suggest that you clean it with a soft, DRY cloth. Never use cleaning compounds or solvents to clean the cabinet as they may damage the finish or remove the labels. Cleaning compounds or liquids could damage the circuitry if any residue falls inside RDD 980. There is NO user serviceable part inside the RDP 980. Please do not open the cabinet as this will expose you to the risk of potentially dangerous high voltage and the risk of shock. This could also damage the circuits and possibly void your warranty.

Please refer to this drawing of the Front Panel when reading the section about Controls on the RDP 980.

CONTROLS ON THE RDP 980 DIGITAL TO ANALOG CONVERTER

The POWER button will turn the RDP 980 ON and OFF. Push it in and the RDP 980 will turn ON. The POWER INDICATOR LIGHT will illuminate at the same time. If you push the Power button again the power will go OFF and the Power Indicator Light will extinguish.

The Front Panel includes the REMOTE SENSOR for receiving the Infra Red signals from the REMOTE CONTROL handset. Please be certain not to block this as the remote control will not function if this is covered or blocked.

The RDP 980 will AUTOMATICALLY select the correct sampling frequency for the incoming digital signal. The RDP 980 will sample and convert 32 kHz, 44.1 kHz or 48 kHz signals from your digital source components. The frequency being sampled will be indicated by an illuminated indicator light. The OUTPUT signals from the RDP 980 are OPTICAL or COAXIAL. If you wish, both may be operated at the same time. This could be useful if you are recording from the Optical output and listening to the Coaxial output, as an example. The small lights over the labels will indicate which output is active when they are ON.

We have included a digital PHASE invert switch on the RDP 980. Many audiophiles have noticed the subtle, but readily apparent, difference between signals that are in correct absolute phase and signals that are in inverted phase. When an instrument is struck or plucked to create a note, it creates a positive energy pulse. Many recording studios do not have correct absolute phase in their recording circuits and the absolute phase of the signals recorded onto the master tape may be in correct absolute phase or inverted phase. With the Phase invert switch it is possible to compare the effect of reversing the absolute phase of the signal. The correct phase setting will exhibit more of a sense of "rightness" or "attack" to the transient signals from bells, triangles, drums, etc.. (This is not the same as incorrect phase when wiring speakers.) With RDP 980 it will be easy to experiment with this aspect of sound reproduction.

We have included a MUTE button for silencing the output of the RDP 980. When the output is muted a small light above the button will be illuminated.

The RDP 980 has a button to select a COAXIAL or OPTICAL INPUT from digital source components. An illuminated indicator light will show whether a Coax(ial) or an Opti(cal) input has been chosen.

The MONITOR (record monitor) button is for use with any digital recorder. It will be especially useful if you have a DAT deck that can read and write digital data at the same time. If you have such a deck (usually only professional machines have this feature) you will be able to compare the source and the recording by using the tape monitor button. When the tape monitor switch is ON a small indicator light will be illuminated above the button. The INPUT chosen before the MONITOR button was pushed will be the only one you can choose until you defeat the tape monitor button. This was done to avoid the possibility that someone would accidentally change the input while making a recording.

We have provided four INPUT SELECTOR buttons (1 to 4) on the RDP 980. These will accept the digital output of a CD player, Laser disc player, Digital Audio Tape recorder (DAT), Mini Disc (MD), Digital Compact Cassette (DCC), satellite broadcast tuner (BS or NICAM) or the digital output from a VCR or 8 mm video tape deck. These inputs will accept 75 ohm coaxial or TOSLINK optical inputs. You may select between optical and coaxial inputs with the INPUT COAX or OPTI buttons on the front panel.

The REMOTE CONTROL for the RDP 980 will operate the INPUT SELECTOR, COAXIAL or OPTICAL INPUTS and OUTPUTS, PHASE, MUTE and the REC/MON switches. The buttons on the remote control are color coded for ease of use. The INPUT SWITCHING, OPTICAL or COAXIAL SWITCHING for the INPUTS and OUTPUTS are grey, the button for PHASE invert is orange and the MUTE button is black.

Please refer to this drawing of the Rear Panel when connecting components to your RDP 980.

CONNECTING THE RDP 980 IN YOUR SYSTEM

The AUDIO OUTPUTS of the RDP 980 are designed for RCA patch cables. Please note the LEFT and RIGHT channel output connections and connect them to the corresponding input channels of your preamplifier or integrated amplifier.

The INPUTS are numbered from 1 to 4 and have COAXIAL and OPTICAL connectors for each. Connect the digital output of the source component to the desired input of the RDP 980. The RECORD/MONITOR connections are clearly labeled and should be connected to the input and output of your digital recorder. IN receives a signal from your digital recorder and OUT sends a signal to your digital recorder. We suggest that the best sound will be obtained from the coaxial 75 ohm inputs and outputs with high quality 75 ohm characteristic impedance patch cables. High performance RCA patch cables will improve the sound of your stereo and we recommend them. Ask your ROTELhi fi AUTHORIZED DEALER for advice about cables for analog and digital signals in your sound system.

A FINAL WORD FROM ROTEL ABOUT THE RDP 980

We have designed this Digital to Analog Converter for high performance using test equipment and the human ear. We believe that both methods are useful in the design of audio electronics. This is a time consuming process but we feel that the music benefits from this care and attention to detail. We realize that there are many choices available in the market today. We thank you again for choosing our RDP 980 Digital to Analog Converter as the centerpiece for the digital components in your system. Enjoy the music!
