Getting Started
Thank you for purchasing the Rotel RA-985BX Stereo Integrated Amplifier. When used in a high-quality music audio system, it will provide years of musical enjoyment. The RA-985BX 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 RA-985BX 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 RA-985BX 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 RA-985BX 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.

In addition the RA-985BX has several features that enhance its ease of operation and its system configuration flexibility. A full function remote control is provided that can operate several other Rotel tuners and cassette decks in addition to the RA-985BX. An IR remote control signal input/output system is provided. This feature, when used in conjunction with Xantech brand Video Link IR signal pick ups and repeaters (sold separately by custom system installers), enables the RA-985BX to pick up IR remote control signals and distribute them to other components. A preamp/power amp jumper set is provided that makes it easy to connect external components, such as surround sound processors. The unique Second Zone output system (when used with an additional power amplifier and speakers) lets the RA-985BX provide sound to another part of your home. You can even listen to a different signal source from the one being played by the main system. The main functions of the RA-985BX are easy to install and use. If you have experience with other stereo systems, you shouldnt find anything perplexing. Simply plug in the associated components and enjoy.

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.

AC Power and Control

AC Power Input

A Few Precautions

Please read this manual carefully. It provides information on how to incorporate the RA-985BX into your system as well as 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 RA-985BX shipping carton and all enclosed packing material for future use. Shipping or moving the RA-985BX 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 RA-985BX. 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.
Because of its high power rating, the RA-985BX can draw considerable current. Therefore, it should be plugged directly into a 2pin polarized wall outlet. Do not use an extension cord. A heavy duty multi-tap power outlet strip may be used if it (and the wall outlet) is rated to handle the current demanded by the RA-985BX and all the other components connected to it.
Note: Do not connect the power cord for a power amplifier to the auxiliary power outlets on the RA-985BX. Power amplifiers often draw more power than these outlets can provide.
Your RA-985BX 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.

Placement

Like all audio components that handle low-level signals, the RA-985BX can be affected by its environment. Do not stack the RA-985BX on top of a power amplifier. This will minimize the chance it will pick up hum or interference. The RA-985BX generates heat as part of its normal operation. The heat sinks and ventilation openings in the amplifier are designed to dissipate this heat. The ventilation slots in the top cover must be open. There should be 10 cm (4 inches) of clearance around the chassis, and reasonable airflow through the installation location, to prevent the amplifier from overheating. Remember the weight of the amplifier when you select an installation location. Make sure that the shelf or cabinet can support its considerable bulk. We recommend installing the RA-985BX 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.

Note: Should you move your RA-985BX amplifier to another country, it is possible to reconfigure it for use on a different line voltage. Do not attempt to perform this conversion yourself. Opening the enclosure of the RA-985BX 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.

Power/Standby Switch

and Power Indicator
The Power Indicator light above the Standby button is always illuminated when the RA-985BX is connected to a live AC outlet. When the Power/Standby is pressed the RA-985BX is turned on and the Volume Control LED is illuminated. Pressing the Standby switch again will put the RA-985BX in standby mode and the Volume Control LED is turned off.

Auxiliary Power Outputs

Second Zone Output Connection

Input Signal Connections

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.
All the inputs of the RA-985BX are line level inputs. These are appropriate 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. If you want to use a phonograph with the RA-985BX, an external phono equalizer, such as the Rotel RQ-970BX must be used. 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 RA-985BX. Ask your authorized Rotel dealer for advice about cables.

Preamp/Power Amp Jumpers

Cassette Remote Connector

Recorder Connections

[See Figure 2 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 RA-985BX remember that the outputs of the recorder must be connected to the tape inputs of the RA-985BX. Similarly the tape outputs of the RA-985BX 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.
Remote Sensor Extension System
[See Figure 1 for input connection illustration.] The RA-985BX has conventional RCA type input connectors, the type found on nearly all audio equipment.
North American models of the RA-985BX have two switched outlets on the back panel. Power is available from these outlets when the RA-985BX is turned on. Power to these outlets is turned off when the RA-985BX is in Standby mode. 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 RA-985BX.
NOTE: Normally the signal supplied to the Recorder Outputs is selected by the Recording Selector 12. However when the Second Zone output function is used, the Recording Selector becomes the source selector for the Second Zone.
[See Figure 3 for the Second Zone output connection illustration.] This output (when used with an additional power amplifier and speakers) lets the RA-985BX provide sound to another part of your home. You can listen to a different signal source from the one being played by the main system or to the same source. See the Second Zone Operation section for more information.
These connectors, labeled Pre Out and Main In, are normally connected by a set of solid metal jumper connectors. They provide a convenient insertion point for virtually any type of signal processor. To use these connectors, pull out the jumper connectors. Using high quality cables, connect the Pre Out connectors to the inputs of the signal processor. Connect the outputs of the signal processor to the Main In connectors. One of the most common uses for these connectors is to incorporate a surround sound processor into the system. Typically the front channel outputs from the signal processor are connected to the Main In of the RA-985BX. The other outputs from the signal processor are connected to other power amplifiers and speakers.
Some Rotel cassette decks can be operated by the RR-927 remote control that come with the RA-985BX. To use this feature connect a standard 8-pin DIN type cable between the Cassette Remote connector on the back of the RA-985BX and the connector on the back of the cassette deck. Control signals from the RR-927 remote control are pick up by the Remote Sensor on the front of the RA985BX and passed to the cassette deck via the cable.

These connectors, when used in conjunction with Xantech brand Video Link IR signal pick ups and repeaters (sold separately by custom system installers), enable the RA-985BX to pick up IR remote control signals and distribute them to other components. Contact your authorized Rotel dealer for more information.
Video Link and Xantech are Trademarks of Xantech Corporation.

Speaker Outputs

The RA-985BX has two sets of speaker outputs, labeled A and B. The Speaker Selector 5 on the front panel controls which set(s) of speakers are operating.
If you are using terminal lugs, connect them to the wires. If you are attaching bare wires directly to the binding posts, separate the wire conductors and strip back the insulation from the end of each conductor. Be careful not to cut into the wire strands. Unscrew (turn counterclockwise) the binding post thumbscrews. Place the connector lug or wire around the binding post shaft. Turn the thumbscrews clockwise to clamp the connector lug or wire firmly in place.

Speaker Selection

If only one set of speakers will be played at any one time, the speakers may have an impedance as low as 4 ohms. If both the A and B sets of speakers will be operated at the same time the speaker should have an impedance of 8 ohms or more. Speaker impedance ratings are less than precise. In practice, very few loudspeakers will present any problems for the RA-985BX. See your authorized Rotel dealer if you have any questions.
Note: Be sure there are no loose wire strands that could touch adjacent wires or connectors.

Front Panel Controls

Volume Control

Speaker Wire Selection

Use insulated two-conductor stranded wire to connect the RA985BX to the speakers. The size and quality of the wire can have an audible effect on the performance of the system. Standard speaker wire will work, but can result in lower output or diminished bass response, particularly over longer distances. In general, heavier wire will improve the sound. For best performance, you may want to consider special high-quality speaker cables. Your authorized Rotel dealer can help in the selection of appropriate cables for your system.

Balance Control

Polarity and Phasing
The polarity the positive/negative orientation of the connections for every speaker and amplifier connection must be consistent so all the speakers will be in phase. If the polarity of one connection is mistakenly reversed, bass output will be very weak and stereo imaging degraded. All wire is marked so you can identify the two conductors. There may be ribs or a stripe on the insulation of one conductor. The wire may have clear insulation with different color conductors (copper and silver). There may be polarity indications printed on the insulation. Identify the positive and negative conductors and be consistent with every speaker and amplifier connection.

Tone Defeat Switch

Bass Control

Speaker Connection

The RA-985BX has two sets of color coded binding posts on the back panel. These connectors accept bare wire, connector lugs, or dual banana type connectors (except in the European Community countries where their use is not permitted). Route the wire from the RA-985BX to the speakers. Give yourself enough slack so you can move the components to allow access to the speaker connectors. If you are using dual banana plugs, connect them to the wires and then plug into the backs of the binding posts. The thumbscrews of the binding posts should be screwed in all the way (clockwise).
The Volume control increases or decreases the volume in both channels at the same time. Turn it clockwise to increase the volume and counterclockwise to decrease the volume.
The Balance Control alters the relative volume level of the two channels. Turn the Balance Control to the right to make the right channel louder. Turn it to the left to make the left channel louder.
When the Tone Defeat switch is set to On the Bass and Treble tone controls can be used to adjust the bass and treble content of the sound. When the Tone Defeat switch is set to Off the tone controls are removed from the signal path. If you are not using the tone controls leave the Tone Defeat switch in the Off position to ensure the purest possible sound.

and Treble Control

When the Tone Defeat switch is set to On turning the tone controls clockwise increases the bass or treble output. Turning the controls counterclockwise decreases the bass or treble output.

Speaker Selector Switch

When the Speaker Selector switch is set to A, speakers connected to the Speaker A terminals 21 will play. When the switch is set to B, speakers connected to the Speaker B terminals 22 will play. When the switch is set to A+B, speakers connected to both sets of terminals will play. The switch may be set to Off when using headphones. See the information in the Speaker Selection section for important information on speaker impedance.

Second Zone Operation

[See Figure 3 and the Second Zone Output Connection section for information on setting up a second zone.]

Listening Selector

Note: All Second Zone functions are controlled by the RR-927 remote control. See the Remote Control Function section for more information
The setting of the Listening Selector controls which of the input sources is heard. The source selected is also the one that is routed through the Preamp/Power Amp Jumper.

Rec/Zone Button

and Zone Indicator

Recording Selector

The setting of the Recording Selector controls which of the input signals goes to the record outputs. When you are not recording, set the Recording Selector 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 RA-985BX. 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. If you wish to duplicate (dub) a recording from one recorder to another, the source unit should be connected to Tape 1 input. The Recording Selector should be set to Tape 1. The unit recording the signal should be connected to Tape 2 output.
To activate the Second Zone function press the Rec/Zone button. The Second Zone Indicator will light. The Recording Selector will then function as the Second Zone source selector. Press the Rec/ Zone button again to return the Recording Selector to its normal function. The Second Zone Indicator will turn off.

Source Selector Buttons

When the Second Zone function is active the Source Selector buttons select the source for the second zone.

Zone Volume Buttons

The buttons labeled < Zone Vol > control the volume of the Second Zone. Press the left button to turn the volume down and the right button to turn the volume up.

Remote Sensor

The Remote Sensor picks up the infra-red signals from the remote control. Do not cover or block the sensor. It must be unobstructed or the remote control will not work properly. The operation of the Remote Sensor can also be affected if it is exposed to bright light, particularly sunlight. In addition remote control functions may not work reliably if the batteries in the RR-927 are weak.

Buttons

are used to program the remote.
See the following section.

RR-927 Remote Control

In addition to the Second Zone functions the RR-927 remote control duplicates most of the functions of the RA-985BX front panel controls. It can also operate all current 900 series remote controllable components. Depending on the components you have, it may be necessary to reprogram the RR-927 with a new code using the procedure described in the Reprogramming section. The RR-927 is initially preset to operate the following components: Amplifier (code A2) RA-985BX, RA-945, RC-995 Tuner (code B1) RTC-940AX, RX-950AX, RT-940AX CD Player (code C1) RCD-970BX, RCD-975 Cassette Deck (code D1) RD-960BX

Protection Circuitry

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 RA-985BX, refer to the suggestions for the following conditions:
The RA-985BX has both thermal and over-current protection circuitry that protects the amplifier against damage in the event of extreme or faulty operating conditions. The 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 shut down the amplifier if temperatures 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. If this happens, turn the amplifier off. Let it cool down for several minutes, and attempt to identify and correct the problem that caused the protection circuitry to engage. When you turn the amplifier back on, the protection circuit will automatically reset and the indicator LED should go out. In most cases, the protection circuitry activates because of a fault condition such as shorted speaker wires, or inadequate ventilation leading to an overheating condition. In very rare cases, highly reactive or extremely low impedance speaker loads could cause the protection circuit to engage. If the protection circuitry triggers repeatedly and you are unable to isolate and correct the faulty condition, contact your authorized Rotel dealer for assistance in troubleshooting.
