PHONO EQUALIZER RQ-970BX

A Few Precautions

Please read this manual carefully. It provides complete informa- tion on how to incorporate the RQ-970BX into your system as well as general information that will help you get optimum sound per- formance. Please contact your authorized Rotel dealer for an- swers 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 ma- terial for future use. Shipping or moving the RQ-970BX in anything other than the original packing material may result in severe dam- age to your amplifier.

Fill out and send in the owner’s 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 pos- sible to reconfigure your amplifier for use on a different line volt- age. 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 de- partment 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 2 and Power Indicator 1

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 Indica- tor 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 install- ing the RQ-970BX in furniture designed to house audio compo- nents. 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 in- stallation of audio components.

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 pick- ing 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.

AC Power and Control

AC Power Input 7

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.

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.

Note: To prevent loud noises that neither you nor your speakers will appreciate, be sure to turn off the power to all the compo- nents in the system before you make any signal connections.

Phono Input Selector Switch (MM/MC) 3

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 set- ting, check the instruction manual for your phono cartridge for in- formation regarding its output voltage and the expected input impedance. The Phono input has 47 kOhms input impedance and

2.5mV sensitivity in the MM position, and 100 Ohms input imped- ance 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 4 and

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.
