A Few Precautions

Please read this manual carefully. In addition to basic installation and operating instruc- tions, it provides valuable information on various RKB-2100 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-2100 shipping carton and all enclosed packing material for future use. Ship- ping or moving the RKB-2100 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 stan- dard equipment rack or placed on a solid surface.

When not using an equipment rack, place the RKB-2100 on a solid, level surface away from sunlight, heat, moisture, or vibration.

11

Don’t stack other components or objects on top of the RKB-2100. Don’t let any liquid fall into the unit.

Likewise, remember the weight of the ampli- fier when you select an installation location. Make sure that the shelf or cabinet can sup- port its considerable bulk.

The RKB-2100 generates heat during normal operation. Do not block ventilation openings.

Allow a minimum of 10 cm or 4 inch- es of unobstructed space around the unit. If installed in a cabinet, make sure that there is adequate ventilation.

Rack Mounting

The RKB-2100 is supplied with two rack mount- ing brackets for installation in standard equip- ment racks. To install these brackets:

1.Hold a bracket against the side of the am- plifier to locate the chassis cover screw that must be removed for clearance. Re- move 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 bot- tom 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 re- move the handles, use the rubber hole plugs supplied with the bracket hardware to fill the exposed holes.

Optional Fan Kit

The RKB-2100’s generous heatsinks provide adequate cooling for most installations. How- ever, when rack mounting or otherwise install- ing 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 me- chanical fan noise during operation. When using the fan cooling, select a location for the amplifier where the noise will not be intrusive.
