Getting Started

Thank you for purchasing the Rotel RKB-650 Six Channel Power Amplifier. When used in a high-quality music or home theater system, your Rotel amplifier will provide years of musical enjoyment.

The RKB-650 is a sophisticated six-channel power amplifier. Discrete output devices, a massive power supply with toroidal transformer, premium components, and Rotel's Balanced Design ensure superb sound quality. High current capability allows the RKB-650 to drive difficult speaker loads with ease.

Features

• Six-channel power amplifier, with 50 watts per channel output into 8 ohms.
• Rack-mountable (standard international 3U rack height). Rack handles or the rack mount kit can be removed for installation in narrower spaces.
• Front panel input level controls. Can be configured three ways: recessed adjustments, knobs for user control, or covered with blanking plugs to prevent user adjustment.
• User-selectable power on/off configuration: manual, automatic signal sensing, or controlled by remote 12 volt trigger signal.
• Provision for installation of optional cooling fan for increased heat dissipation and performance.
• Protection circuitry against fault conditions with front panel indicators.

A Few Precautions

Please read this manual carefully. In addition to basic installation and operating instructions, it provides valuable information on various RKB-650 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 RKB-650 shipping carton and all enclosed packing material for future use. Shipping or moving the RKB-650 in anything other than the original packing material may result in severe damage to your amplifier.

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.

Placement

The amplifier can be mounted in a standard equipment rack or placed on a solid surface.

When not using an equipment rack, place the RKB-650 on a solid, level surface away from sunlight, heat, moisture, or vibration.

Don't stack other components or objects on top of the RKB-650. Don't let any liquid fall into the unit.

Likewise, remember the weight of the amplifier when you select an installation location. Make sure that the shelf or cabinet can support its considerable bulk.

The RKB-650 generates heat during normal operation. Do not block ventilation openings. Allow a minimum of 10cm or 4 inches of unobstructed space around the unit. If installed in a cabinet, make sure that there is adequate ventilation.

Rack Mounting

The RKB-650 is supplied with two rack mounting brackets for installation in standard equipment racks. To install these brackets:

1. Hold a bracket against the side of the amplifier to locate the chassis cover screw that must be removed for clearance. Remove this screw with a Phillips head screw driver and replace it with one of the short Philips head machine screws enclosed with the brackets.
2. Install the rack mount bracket, inserting three of the long Philips head machine screws through the bracket and into the threaded holes in the side of the amplifier.
3. Repeat for the bracket on the other side of the amplifier.

NOTE: You can remove the feet from the bottom of the amplifier if necessary for clearance in the rack. Save the feet and hardware for future use.

After the adaptors are installed, use four bolts supplied with your equipment rack to mount the amplifier. Be sure that all four bolts are tightened properly.

Rack Handles

The rack mount brackets are supplied with handles which can be installed or removed. The handles are installed with two of the long Philips head machine screws inserted through the rack mount bracket and into the threaded holes in the handle. If you do remove the handles, use the rubber hole plugs supplied with the bracket hardware to fill the exposed holes.

Optional Fan Kit 5

The RKB-650's generous heatsinks provide adequate cooling for most installations. However, when rack mounting or otherwise installing the amplifier in a confined space near other heat-generating components, additional cooling may be desirable. The optional RKBF-1 fan kit can be easily installed for additional forced air cooling. In addition to lowering operating temperatures, the optional fan kit improves the performance of the amplifier, especially when driving difficult loudspeaker loads. See your Rotel dealer for information on the optional fan kit.

NOTE: The optional cooling kit generates mechanical fan noise during operation. When using the fan cooling, select a location for the amplifier where the noise will not be intrusive.

AC Power and Control

AC Power Input 12

Your RKB-650 is configured at the factory for the proper AC line voltage in the country where you purchased it (USA: 120 volts/60 Hz, Europe: 230 volts/50 Hz). The AC line configuration is noted on a label on the back panel.

The RKB-650 is supplied with the proper AC power cord. Use only this cord or an exact equivalent. Do not modify the supplied cord. Do not use an extension cord.

Be sure the power switch on the front panel of the RKB-650 is turned off. Then, plug one end of the cord into the AC power connector on the back panel of the amplifier. Plug the other end into an appropriate AC outlet.

If you are going to be away from home for an extended period of time, it is a sensible precaution to unplug your amplifier.

Power Switch 1 Indicator LED 2

The power switch is located on the left side of the front panel. To turn the amplifier on (or to activate either of the optional automatic power-on modes), push the switch in. The LED indicator above the switch will light, indicating that the amplifier is turned on. To turn the amplifier off, push the button again and return it to the out position.

Auto Turn On/Off Mode Selector 9

The RKB-650 provides three different options for manual or automatic power on/off operation. These modes are selectable using a three-position slide switch on the back panel as follows:

• With the switch in the OFF position, the amplifier is turned on or off manually using the front panel power switch. Also use this mode if you are using a switched AC outlet to control power to the amplifier.

• With the switch in the SIGNAL SENSE position, the amplifier turns on automatically when a signal is detected at the inputs. The amplifier will go into standby mode several minutes after no signal is no longer present. The front panel power switch overrides this function. It must be ON for the signal sensing to work. Turning the switch OFF cuts power to the amplifier, regardless of whether or not a signal is present.

• With the switch in the 12V TRIG position, the amplifier is turned on automatically when a 12 volt trigger signal is present at the 12V TRIG input to the left of the switch. The amplifier goes into standby mode if the +12 volt signal is not present. The front panel POWER SWITCH overrides this function. It must be ON for the +12V trigger to work. Turning the switch OFF cuts power to the amplifier, regardless of whether or not a trigger signal is present.

12V Trigger Input 8

An input jack for connecting the wires carrying a +12 volt trigger signal from a Rotel preamp or surround sound processor to turn the amplifier on and off. To use this feature the adjacent slide switch must be placed to the left position (see previous section).

The TRIGGER INPUT accepts any control signal (AC or DC) ranging from 3 volts to 30 volts. Using a cable with mono 3.5mm mini-plugs on both ends. The +12VDC signal appears at the "tip" connector.

12V Trigger Output 8

The 12V TRIG jack labeled OUT is used to pass the remote turn-on signal to a second Rotel amplifier. Any 12V Trigger signal at the INPUT jack will be passed through to the OUT jack.

Circuit Breaker 1

A 16 amp circuit breaker on the rear panel protects the amplifier's electrical circuit. Generally, the circuit breaker will only open under a fault condition which results in excessive current draw. To reset the circuit breaker, press the button. Should it repeatedly open, contact your authorized Rotel dealer for troubleshooting assistance.

Protection Indicators 3

A thermal protection circuit protects the amplifier against potential damage in the event of extreme or faulty operating conditions. Unlike many designs, the RKB-650's protection circuit is independent of the audio signal and has no impact on sonic performance. Instead, the protection circuit monitors the temperature of the output devices and shuts down the amplifier if temperatures exceed safe limits.

In addition, the RKB-650 includes overcurrent protection which operates only when load impedance drops too low.

Should a faulty condition arise, the amplifier will stop playing and one or more of the PROTECTION LEDs on the front panel will light.

If this happens, turn the amplifier off, let it cool down for several minutes, and attempt to identify and correct the problem. There are independent PROTECTION LEDs for each pair of channels which may help in troubleshooting the cause of the problem. When you turn the amplifier back on, the protection circuit will automatically reset and the PROTECTION LEDs should go out.

In most cases, the protection circuitry activates because of a fault condition such as shorted speaker wires, or inadequate ventilation causing an overheating condition. In very rare cases, highly reactive or extremely low impedance speaker loads could cause the protection circuit to engage.

Signal Connections

The RKB-650 provides standard conventional input connections — unbalanced RCA type connections as found on nearly all audio equipment.

There is also a pair of SIGNAL OUTPUT LINK connections for passing the input signal connected to the "A" pair of channels on to another audio component. Additionally, the input signal to the "A" pair of channels can be automatically linked to the inputs for the "B" and/or "C" channels, so that a separate input signal cable is not required for those channels, for example in large systems where the RKB-650 is being used to drive multiple pairs of speakers.

RCA Inputs 6

See Figure 2

There are two RCA inputs for each of the three pair of amplifier channels. These RCA inputs accept audio signals from preamplifiers or surround sound processors. Use high quality audio interconnect cables for best performance.

For each pair of amplifier channels, connect the left channel output of your preamp to the LEFT INPUT on the RKB-650. Connect the right channel of your preamp to the RIGHT INPUT. Make sure that the input slide switch to the right of the RCA inputs is in the STE-REO position.

Linking the Inputs 6

You can link the inputs for groups "B" and/or "C" to the "A" inputs by placing the input slide switch to the right of each pair of RCA inputs in the LINK position. When linked, no input connection is required for that group. The input signal from the "A" group is sent to the linked pair of channels, allowing you to use four or six amplifier channels with the same stereo input signals.

Input Level Controls 4

Three controls on the front panel, one for each pair of channels, provide input level adjustments. These allow you to adjust the gain of the amplifier to match other components in the system. The A level control changes the gain of the "A" channels; the B level control changes the "B" channels; the C level control changes the "C" channels.

To adjust these controls, use a small, flatblade screwdriver. Turn the control clockwise to increase gain. Turn counterclockwise to reduce gain.

For easier adjustment, install the supplied volume control knobs by gently pressing them onto the control shafts. Alternatively, you can prevent inadvertant adjustment by installing the supplied rubber plugs to conceal the volume controls.

Signal Output Link Z

This pair of RCA connections can be used to pass the unprocessed input signals to another audio component, for example to "daisy-chain" an additional amplifier to drive a second set of speakers. The input signals connected to the "A" channels is also available at these LINK outputs.

NOTE: These input signals from the "A" channels can also be linked to the "B" and/or "C" inputs by playing the INPUT SELECT switch associated with that pair of channels in the LINK position.

Speakers

The RKB-650 has three groups of speaker connectors, one for each pair of amplifier channels.

Speaker Selection

The nominal impedance of the loudspeaker(s) connected to the RKB-650 should be a minimum of 4 ohms. When driving multiple pairs of speakers connected in parallel, the effective impedance the amplifier sees is cut in half. For example, when driving two pair of 8 ohm speakers, the amplifier sees a 4 ohm load. When driving multiple speakers in parallel, select speakers with a nominal impedance of 8 ohms or higher.

Speaker Wire Selection

Use insulated two-conductor stranded wire to connect the RKB-650 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.

Polarity and Phasing

The polarity or 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 speaker 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.

Speaker Connections 10

See Figure 2

The RKB-650 has two pair of color coded connections for each group of amplifier channels, one for the left speaker, the other for the right speaker. Labels above the connectors show the proper connections for connecting speakers. These speaker connectors accept bare wire, connector lugs, or "banana" type connectors (except in the European Community countries where their use is not permitted).

Route the wires from the RKB-650 to the speakers. Give yourself enough slack so you can move the components enough to allow access to the speaker connectors.

If you are using banana plugs, connect them to the wires and then plug into the backs of the speaker connectors. The collars of the speaker connectors should be screwed in all the way (clockwise).

If you are using terminal lugs, connect them to the wires. If you are attaching bare wires directly to the speaker connectors, 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 speaker connector collar. Place the connector lug around the shaft, or insert the bundled wire into the hole in the shaft. Turn the collars clockwise to clamp the connector lug or wire firmly in place.

NOTE: Be sure there are no loose wire strands that could touch adjacent wires or connectors.

For each group of channels, connect the left speaker to the pair of speaker connectors labeled LEFT. Connect the right speaker to the speaker connectors labeled RIGHT. Follow the labels printed above the connectors, Make sure that the positive terminal of the speaker is connected to the + terminal on the amplifier. Make sure that the negative terminal of the speaker is connected to the - terminal of the amplifier.

Troubleshooting

Most difficulties in audio systems are the result of poor or wrong 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 RKB-650, refer to the suggestions for the following conditions:

Front Panel Power Indicator Is Not Lit

No main power to the RKB-650. Check AC power connections at the amplifier and the AC outlet. Check the front panel power switch. Make sure that it is set to the ON position. If using signal sensing auto power-on, make sure that a signal is present at the inputs. If using 12V trigger power-on, make sure that a trigger signal is present at rear panel 12V TRIG IN connector.

No Sound

If the amp is getting AC power, but is producing no sound, check the PROTECTION INDICATORS on the front panel. If lit, see below. If not, check all of your connections and control settings on associated components.

Protection Indicator Is Lit

The front panel PROTECTION INDICATORS light when the RKB-650 protection circuits have shut off the amplifier. Typically, this occurs only when the ventilation openings are blocked, when there is faulty speaker wiring, or after a period of extreme use. Turn off the system and wait for the amp to cool. Then push the front panel power switch in and out to reset the protection devices. If the problem is not corrected or reoccurs, there is a problem with the system or the amplifier itself.
