About Rotel
Our story began nearly 50 years ago. Over the decades, we have received hundreds of awards for our products and satisfied hundreds of thousands of people who take their entertainment seriously - like you!
Rotel was founded by a family whose passionate interest in music led them to manufacture high-fi delity components of uncompromising quality. Through the years, that passion has remained undiminished and the family goal of providing exceptional value for audiophiles and music lovers, regardless of their budget, is shared by all Rotel employees.
Rotel's engineers work as a close team, listening to, and fi ne tuning, each new product until it reaches their exacting musical standards. They are free to choose components from around the world in order to make that product the best they can. You are likely to fi nd capacitors from the United Kingdom and Germany, semiconductors from Japan or the United States, while toroidal power transformers are manufactured in Rotel's own factory.
We all have concerns about our environment. And, as more and more electronics are produced and later discarded, it is especially important for a manufacturer to do all it can to engineer products that have a minimum negative impact on landfi ll sites and water tables.
At Rotel, we are proud to do our part. We have reduced the lead content in our electronics by using special ROHS solder, while our new Class D (not digital) amplifiers are up to five times more efficient than our legacy designs and still deliver power and performance. These products run cool, give minimum wasted energy, are good for the environment and give better sound too.
Finally, we have printed this brochure on recycled paper stock.
While we understand that these are small first steps, they are still important ones. And we continue to pursue new methods and materials for a cleaner and greener manufacturing process.
All of us at Rotel thank you for buying this product. We are sure it will bring you many years of enjoyment.
A Word About Watts
This RMB-1565 power output is quoted as 100 watts for each channel, when all fi ve channels are operating together at full power. The RMB-1575 produces 250 watts per channel, also with all fi ve channels operating at full power.
Rotel has chosen to specify the power output in this way because, in Rotel's experience, it gives the truest value of the receiver or amplifier's power capability.
When comparing specifications for different products, you should be aware that power output is often specified in other ways, so you may not be comparing like with like.
For example, the power output may be quoted with only one channel operating, giving a higher maximum figure. The highly regulated power supplies of the Rotel Class D amplifiers ensures that they will produce the full specified power output to one or all channels.
A loudspeaker's impedance rating indicates the electrical resistance or load it offers when connected to the amplifier, usually 8 ohms or 4 ohms. The lower the impedance, the more power the speaker will need. In effect, a 4 ohm speaker will require twice as much power as an 8 ohm speaker.
So ideally, the amplifi er should be give double the power into a 4 ohm load – a rating of 100 watts into an 8 ohm load should become 200 watts into 4 ohms. Using lower impedance speakers makes greater demands on the amplifi er's power supply, because it will be drawing more current and giving off more heat.
However, Rotel amplifiers are designed to work into any speaker impedance between 8 and 4 ohms, and with all the channels working up to their full power. Because the Rotel design is optimized for use with all channels operating together, Rotel is able to specify the true power output for all channels.
This can be important for your enjoyment, too. When watching movies, it's nice to have the amplifi er able to reproduce full power into all the channels at the same time, especially in the case of a volcano exploding!
Getting Started
Thank you for purchasing the Rotel RMB-1565 or RMB-1575 Five-Channel Power Amplifi er. When used in a high-quality music or home theater system, your Rotel amplifi er will provide years of musical enjoyment.
The RMB-1565 and RMB-1575 are sophisticated fi ve-channel power amplifi ers. Their Class D amplifi er circuitry, switching power supply, premium components, and Rotel's Balanced Design ensure superb sound quality. High current ` allows the RMB-1565 and RMB-1575 to drive diffi cult speaker loads with ease.
Operating Features
• Five amplifi er channels
- User selectable power on/off configuration: manual, or controlled by remote 12 volt trigger signal
• Protection circuitry with front panel indicator
A Few Precautions
Please read this manual carefully. In addition to installation and operating instructions, it provides information on various system configurations. 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 amplifi er shipping carton and packing material for future use. Shipping or moving the amplifi er in anything other than the original packing material may result in severe damage to your amplifi er.
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.
Placement
The RMB-1565 and RMB-1575 generate heat as part of their normal operation. The heat sinks and ventilation openings in the amplifi er are designed to dissipate this heat. The ventilation slots in the top cover must be unobstructed. There should be 10 cm (4 inches) of clearance around the chassis, and reasonable airfl ow through the installation location, to prevent the amplifi er from overheating. Likewise, remember the weight of the amplifi er when you select an installation location. Make sure that the shelf or cabinet can support its weight.
AC Power and Control
AC Power Input 7
The amplifi er is supplied with the proper AC power cord. Use only this cord or an exact equivalent. Do not use an extension cord. A heavy duty multi-tap power outlet strip may be used, but only if it is rated to handle the current demand of the amplifi er.
The RMB-1565 will automatically confi gure itself for the proper AC line voltage rating, from 110 volts to 240 volts, at 50/60Hz. No setting is required to match the unit to your local voltage.
The RMB-1575 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.
Note: Should you move your RMB-1575 to another country, it is possible to configure your amplifier for use on a different line voltage. Do not attempt to perform this conversion yourself. Opening the enclosure of the RMB-1575 exposes you to dangerous voltages. Consult a qualified technician or the Rotel factory service department for information.
Plug the supplied cord into the AC INPUT receptacle 7 on the back panel of the unit. After all connections have been made, plug the other end into an appropriate AC wall outlet.
Note: 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 and Indicator 1
The Power Switch is located on the front panel. To turn the amplifi er on (or to activate either of the optional automatic power-on modes), push the switch in. The ring around the switch will light, indicating that the amplifi er is turned on. To turn the amplifi er off, push the button again and return it to the out position.
Turn On/Off Mode Selector 6
The amplifi er can be turned on and off manually, or automatically by using its "12V Trigger" system. The Turn On/Turn Off Mode selector switch selects which method is used.
- With the switch in the OFF position, the amplifi er is turned on or off manually using the front panel power switch. Use this mode if you are using a switched AC outlet to control power to the amplifi er.
- With the switch in the 12V TRIG position, the amplifier is turned on automatically when a 12 volt trigger signal is applied to the 3.5mm jack labeled IN. 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 and Output 5
The jack labeled IN is for connecting the 3.5mm Plug/Cable carrying a +12 volt trigger signal to turn the amplifi er on and off. To use this feature the adjacent switch must be placed to the 12V TRIG position (see previous section). This input accepts any control signal (AC or DC) ranging from 3 volts to 30 volts.
The jack labeled OUT is for connecting another 3.5mm plug/cable to provide a 12V trigger signal to other components. The 12V output signal is available whenever a +12 volt trigger signal is applied to the IN connector.
Protection Indicator 2
Thermal and protection circuits protect the amplifi er against potential damage in the event of extreme or faulty operating conditions. Unlike many designs, the protection circuit in the RMB-1565 and RMB-1575 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 amplifi er if safe limits are exceeded.
In addition, the amplifier includes over-current protection which operates only when load impedances drop too low. This protection is independent for each of the fi ve channels.
Should a faulty condition arise, the amplifier channel at fault will stop playing and the PROTECTION LED on the front panel will light.
If this happens, turn the amplifi er off, let it cool down for several minutes, and attempt to identify and correct the problem. When you turn the amplifi er back on, the protection circuit will automatically reset and the PROTECTION 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.
Input Signal Connections 4
See Figure 2
The RMB-1565 and RMB-1575 have standard unbalanced RCA-type input connectors, the type used on nearly all audio equipment. There is an RCA input for each of the five amplifier channels. These RCA inputs accept audio signals from preamplifi ers or surround sound processors. Use high quality audio interconnect cables for best performance.
Speakers
The RMB-1565 and RMB-1575 have five sets of speaker connectors, one for each amplifier channel.
Speaker Selection
The nominal impedance of the loudspeaker(s) connected to each channel of the amplifier in the various operating modes should be no lower than 4 ohms.
Speaker Wire Selection
Use insulated two-conductor stranded wire to connect the amplifier 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 – 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.
Speaker Connections 3
See Figure 2
Note: The following text describes both binding post and plug-in connections. DO NOT use both connection methods in combination to connect multiple speakers.
The RMB-1565 and RMB-1575 have two color coded terminals for each amplifier channel. 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 amplifier to the speakers. Give yourself enough slack so you can move the components 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.
Troubleshooting
Most diffi culties in audio systems are the result of poor or wrong connections, or improper control settings. If you encounter problems, isolate the area of the diffi culty, check the control settings, determine the cause of the fault and make the necessary changes. If you are unable to get sound from the amplifi er, refer to the suggestions for the following conditions:
Front Panel Power Indicator Is Not Lit
No mains power to the amplifi er. Check AC power connections at the amplifi er and the AC outlet. Check the front panel power switch. Make sure that it is set to the ON position. If using 12V trigger power-on, make sure that a trigger signal is present at rear panel screw terminals.
No Sound
If the amp is getting AC power, but is producing no sound, check the PROTECTION INDICATOR on the front panel. If lit, see below. If not, check all of your connections and control settings on associated components. Make sure that your input connections and speaker connections match your selected configuration.
Protection Indicator Is Lit
The front panel PROTECTION INDICATOR is lit when the amplifi er protection circuits have shut off the amplifi er. Typically, this occurs only when the amplifi er has overheated, 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 amplifi er itself.
