Owner’s Manual

Features

The Roland Studio Monitor RSM-90 speaker system was designed, developed, and manufactured in the United States. The high-quality sound these studio monitors deliver make them perfect for mixing duties in digital recording studios.

2-Way Speakers with Superior Sound Quality

To achieve such high-quality sound, the low-frequency driver uses a 160-mm polypropylene foam cone, and the high-frequency driver features a dome tweeter with a high-precision face plate.

3/4’’ MDF Cabinets with 1” MDF Baffles

Cabinet construction prevents excess vibration, which greatly improves sound quality. * MDF = Middle Density Fiberboard

Bi-Wiring Connections

Bi-wiring reduces problems (intermodulation distortion) caused by the effect the high-frequency and low-frequency drivers have on each other.

Gold-Plated Post Connectors

Gold plating provides long-lasting protection for the connectors, preventing degradation of sound quality over time. Additionally, the binding post connectors are compatible with heavy-gauge speaker cables.

Magnetically Shielded Low- and High-Frequency Drivers

This allows you to use the speakers next to CRT displays.

Front-Facing Bass Reflex Ports

These ports ensure consistent low-end sound regardless of placement.

Important Notes

Placement

354b

• Do not expose the unit to direct sunlight, place it near devices that radiate heat, leave it inside an enclosed vehicle, or otherwise subject it to temperature extremes. Also, do not allow lighting devices that normally are used while their light source is very close to the unit (such as a piano light), or powerful spotlights to shine upon the same area of the unit for extended periods of time. Excessive heat can deform or discolor the unit.

355

• To avoid possible breakdown, do not use the unit in a wet area, such as an area exposed to rain or other moisture.

356

• Do not allow rubber, vinyl, or similar materials to remain on the unit for long periods of time. Such objects can discolor or otherwise harmfully affect the finish.

357

• Do not put anything that contains water (e.g., flower vases) on the unit. Also, avoid the use of insecticides, perfumes, alcohol, nail polish, spray cans, etc., near the unit. Swiftly wipe away any liquid that spills on the unit using a dry, soft cloth.

Maintenance

401a

• For everyday cleaning wipe the unit with a soft, dry cloth or one that has been slightly dampened with water. To remove stubborn dirt, use a cloth impregnated with a mild, non-abrasive detergent. Afterwards, be sure to wipe the unit thoroughly with a soft, dry cloth.

402

• Never use benzine, thinners, alcohol or solvents of any kind,

to avoid the possibility of discoloration and/or deformation.

Additional Precautions

558b

• To avoid disturbing your neighbors, try to keep the unit’s volume at reasonable levels (especially when it is late at night).

559a

• When you need to transport the unit, package it in the box (including padding) that it came in, if possible. Otherwise, you will need to use equivalent packaging materials.
