Getting Started

Thank you for purchasing the Rotel RQ-970BX Phono Preamp Equalizer. When used in a high-quality music audio system, it will provide years of musical enjoyment. With the increased use of digitally based audio media, many modern high performance audio components lack the circuitry needed to handle the signals produced by phono systems. The RQ-970BX is a high performance phono equalizer. The output signal from the RQ-970BX can be plugged into any line level input. The RQ-970BX uses the same sophisticated circuit designs and high quality components that have made Rotel a world-wide standard of performance. This type of design is more expensive to manufacture, but it is better for the music. The RQ-970BX is straightforward in its installation and operation. If you have experience with other stereo systems, you shouldnt find anything perplexing. Simply plug in the associated components and enjoy.

A Few Precautions

Please read this manual carefully. It provides complete information on how to incorporate the RQ-970BX into your system as well as general information that will help you get optimum sound performance. 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 RQ-970BX shipping carton and all enclosed packing material for future use. Shipping or moving the RQ-970BX in anything other than the original packing material may result in severe damage to your amplifier. Fill out and send in the owners registration card packed with the RQ-970BX. 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 ever required.
Note: Should you move your RQ-970 to another country, it is possible to reconfigure your amplifier for use on a different line voltage. Do not attempt to perform this conversion yourself. Opening the enclosure of the RQ-970 exposes you to dangerous voltages. Consult a qualified service person or the Rotel factory service department for information.
If you are going to be away from home for an extended period of time such as a month-long vacation, it is a sensible precaution to unplug the RQ-970 (as well as other audio and video components) while you are away.

Power Switch

The Power switch is located on the left side of the front panel. When it is pressed the RQ-970 is turned on and the Power Indicator light is illuminated. Pressing the Power switch again will turn the RQ-970 off.

Placement

Like all audio components that handle low-level signals, the RQ-970BX can be affected by its environment. Do not stack the RQ-970BX on top of a power amplifier. This will minimize the chance it will pick up hum or interference. We recommend installing the RQ-970BX 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.

Input Connection

[See Figure 2 for typical system connection illustration.] The RQ-970BX has conventional RCA type input connectors, the type found on nearly all audio equipment.

Cables

Be sure to keep the power cords, digital signal cables and regular audio signal cables in your installation away from each other. This will minimize the chance of the regular 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.

Note: To prevent loud noises that neither you nor your speakers will appreciate, be sure to turn off the power to all the components in the system before you make any signal connections.
Phono Input Selector Switch (MM/MC)

AC Power and Control

AC Power Input
The RQ-970BX does not use a significant amount of power. The most convenient power source may be a switched power outlet on another component. Then you can leave the power switch of the RQ-970 in the on position and it will be turned on and off with the other components. Your RQ-970 is configured at the factory for the proper AC line voltage in the country where you purchased it (either 115 volts AC or 230 volts AC with a line frequency of either 50 Hz or 60 Hz). The AC line configuration is noted on the back panel.
The RQ-970BX can accept inputs from moving magnet (MM) or moving coil (MC) phono cartridges. Set the Phono Input Selector Switch as appropriate for the phono cartridge you are using. Leave the switch button in the out position for a moving magnet cartridge; push the switch in for a moving coil cartridge. Some high output moving coil cartridges are designed to operate in the moving magnet position. If you are in doubt about the correct setting, check the instruction manual for your phono cartridge for information regarding its output voltage and the expected input impedance. The Phono input has 47 kOhms input impedance and 2.5 mV sensitivity in the MM position, and 100 Ohms input impedance and 210 V sensitivity in the MC position. If you still have questions about the proper setting of the phono input selector switch, consult your authorized Rotel dealer.
Phono Input Connection Ground Terminal 5
Plug the cable from the turntable into the appropriate left and right phono inputs. If the turntable has a ground wire connect it to the screw terminal 5 to the right of the inputs. It will help prevent hum and noise.

Getting Started
Thank you for purchasing the Rotel RC-971 Stereo Control Amplifier. When used in a high-quality music audio system, it will provide years of musical enjoyment. The RC-971 is a full featured, high performance preamplifier. All aspects of the design have been optimized to retain the full dynamic range and subtle nuances of your music. The RC-971 has a highly regulated power supply incorporating a Rotel custom-designed power transformer. This low impedance power supply has ample power reserves, which enables the RC-971 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 RC-971 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 RC-971 circuitry uses metal film resistors and polystyrene or polypropylene capacitors in important signal paths. All aspects of this design have been examined with the final goal being faithful reproduction of music. The RC-971 is straightforward in its installation and operation. If you have experience with other stereo systems, you shouldnt find anything perplexing. Simply plug in the associated components and enjoy.

A Few Precautions

Please read this manual carefully. It provides complete information on how to incorporate the RC-971 into your system as well as general information that will help you get optimum sound performance. 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 RC-971 shipping carton and all enclosed packing material for future use.

Fill out and send in the owners registration card packed with the RC-971. 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 ever required. Your RC-971 is configured at the factory for the proper AC line voltage in the country where you purchased it (either 115 volts AC or 230 volts AC with a line frequency of either 50 Hz or 60 Hz). The AC line configuration is noted on a decal on the back panel.
Note: Should you move your RC-971 amplifier to another country, it is possible to reconfigure your amplifier for use on a different line voltage. Do not attempt to perform this conversion yourself. Opening the enclosure of the RC-971 exposes you to dangerous voltages. Consult a qualified service person or the Rotel factory service department for information.
If you are going to be away from home for an extended period of time such as a month-long vacation, it is a sensible precaution to unplug your amplifier (as well as other audio and video components) while you are away.

Placement

Like all audio components that handle low-level signals, the RC-971 can be affected by its environment. Do not stack the RC-971 on top of a power amplifier. This will minimize chance it will pick up hum or interference. We recommend installing the RC-971 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.

Power Switch

and Power Indicator
The Power switch is located on the left side of the front panel. When it is pushed in the RC-971 is turned on and the Power Indicator light is illuminated. Press the Power switch again to turn the RC-971 off.

Auxiliary Power Outputs

(U.S.A. version)

Cables

Be sure to keep the power cords, digital signal cables and regular audio signal cables in your installation away from each other. This will minimize the chance of the regular 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 RC-971 has two switched outlets on the back panel. Power is available from these outlets when the RC-971 is turned on. These outlets can provide up to a total of 400 watts. They are appropriate for supplying power to signal sources, such as CD players, tuners, or tape decks. They should not be used for power amplifiers. Connecting components that will draw more than 400 watts to these outputs could damage the Standby switch in the RC-971.

AC Power and Control

AC Power Input
The RC-971 does not use a significant amount of power. However there are two auxiliary power outlets on the back of the unit, which can be used to supply power for other units. Consequently it is usually best to plug the RC-971 directly into a 2-pin polarized wall outlet. Avoid the use of extension cords. A heavy duty multitap power outlet strip may be used if it (and the wall outlet) is rated to handle the current demanded by the components connected to it.
Note: Do not connect the power cord for a power amplifier to the auxiliary power outlets on the RC-971. Power amplifiers often draw more power than these outlets can provide.

Input Signal Connections

Output Connections
[See Figure 3 for input connection illustration.] The RC-971 has conventional RCA type input connectors, the type found on nearly all audio equipment.
Note: To prevent loud noises that neither you nor your speakers will appreciate, make sure the system is turned off when you make any signal connections.
The CD, Tuner, and Aux inputs of the RC-971 are line level inputs. These are for connecting components such as CD players, Hi Fi or NICAM Stereo video cassette recorders, tuners for audio or video, Laser Disc players or the analog output from a CD ROM drive. The Left and Right channels are clearly labeled and should be connected to the corresponding channels of the source component. The Left RCA connectors are white, the Right connectors are red. Use high quality RCA cables for connecting input source components to the RC-971. Ask your authorized Rotel dealer for advice about cables.

Front Panel Controls

Volume Control
Note: The addition of a Rotel RQ-970BX Phono Equalizer enables you to connect a phonograph to the RC-971. See your authorized Rotel dealer for more information.

Tone On/Off Switch

Recorder Connections
[See Figure 4 for recorder connection illustration.] The Tape 1 and Tape 2 inputs and outputs can be connected to any record/playback device that accepts standard line level analog input and output signals. Typically that will be a conventional tape recorder. When connecting a recorder to the RC-971 remember that the outputs of the recorder must be connected to the tape inputs of the RC-971. Similarly the tape outputs of the RC-971 must be connected to the inputs of the recorder. As with other sources be sure to connect the Left and Right channels of each device to the proper channels on the associated components. Use high quality connecting cables to prevent loss of sound quality.

Bass and Treble Controls

[See Figure 2 for RCA output connection illustration.] The RC-971 has RCA-type output connectors that are compatible with the inputs of most power amplifiers. Use high quality cables and be sure to connect the Left and Right channel outputs of the RC-971 to the correct channels of the amplifier. Note: There are two sets of outputs on the RC-971. The second set of outputs may be used in custom system configurations to drive a second power amplifier or to supply a signal to a special signal processor.
The front panel Volume control is actually two separate controls. The control knobs are friction connected, so both controls normally operate together. Turn the controls clockwise to increase the volume, or counterclockwise to decrease the volume. The two controls can be operated separately by holding one control knob while turning the other. Normally this is necessary only to compensate for problems in the program material.
When the switch is in the Off position the tone control circuits are bypassed to ensure the purest possible sound. Leave the switch in the Off position unless you want to use the tone controls. Turn the switch to the On position if you want to adjust the tone controls.
When the Tone Switch is in the On position, turning the Bass and Treble controls adjusts the tone balance of the sound. Turn the controls clockwise to increase the bass or treble output. Turn the controls counterclockwise to decrease the bass or treble output. A properly set up high-performance audio system produces the most natural sound with little or no adjustment of the tone controls. Use these controls sparingly. Be particularly careful when turning the controls up (clockwise). This increases the power output in the bass or treble range, increasing the load on the amplifier and speakers.

Listening Selector

The setting of the Listening Selector controls which of the input signals goes to the main outputs and onto the power amplifier or, more simply, which source is heard.

Troubleshooting

Most difficulties in audio systems are the result of incorrect connections, or improper control settings. If you encounter problems, isolate the area of the difficulty, check the control settings, determine the cause of the fault and make the necessary changes. If you are unable to get sound from the RC-971, refer to the suggestions for the following conditions:

Recording Selector

The setting of the Recording Selector controls which of the input signals goes to the record outputs. When you are not recording, the Recording Selector should be set to the Off position to minimize the chance of interference from other components in the system. Having a separate Recording and Listening selector adds a significant degree of flexibility in how you can use the RC-971. For example by setting the Record Selector to CD and the Listening Selector to Tuner you could record a CD onto a tape while listening to the tuner. There is no Tape 2 position on the Recording Selector. Consequently, if you wish to duplicate (dub) a recording from one recorder to another, the source unit must be connected to Tape 1 input. Set the Recording Selector to Tape 1. Connect the unit recording the signal to the Tape 2 output.
Power Indicator Is Not Lit
The Power Indicator should be lit whenever the RC-971 is plugged into the wall power outlet and the Power Switch is pushed in. If it does not light, test the power outlet with another electrical device, such as a lamp. Be sure the power outlet being used is not controlled by a switch that has been turned off.

Fuse Replacement

If another electrical device works when plugged into the power outlet, and the Power Indicator still will not light, it indicates that the internal power fuse may have blown. If you believe this has happened, contact your authorized Rotel dealer to get the fuse replaced.
