Power Supply

301

• Do not connect this unit to same electrical outlet that is being used by an electrical appliance that is controlled by an inverter (such as a refrigerator, washing machine, microwave oven, or air conditioner), or that contains a motor. Depending on the way in which the electrical appliance is used, power supply noise may cause this unit to malfunction or may produce audible noise. If it is not practical to use a separate electrical outlet, connect a power supply noise filter between this unit and the electrical outlet.

307

• Before connecting this unit to other devices, turn off the power to all units. This will help prevent malfunctions and/or damage to speakers or other devices.

308

• Although the LEDs are switched off when the POWER switch is switched off, this does not mean that the unit has been completely disconnected from the source of power. If you need to turn off the power completely, first turn off the POWER switch, then unplug the power cord from the power outlet. For this reason, the outlet into which you choose to connect the power cord’s plug should be one that is within easy reach and readily accessible.

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

553

• Use a reasonable amount of care when using the unit’s buttons, sliders, or other controls; and when using its jacks and connectors. Rough handling can lead to malfunctions.

556

• When connecting / disconnecting all cables, grasp the connector itself—never pull on the cable. This way you will avoid causing shorts, or damage to the cable’s internal elements.

557

•A small amount of heat will radiate from the unit during normal operation.

558a

• To avoid disturbing your neighbors, try to keep the unit’s volume at reasonable levels. You may prefer to use headphones, so you do not need to be concerned about those around you (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.

562

• Use a cable from Roland to make the connection. If using some other make of connection cable, please note the following precautions.

• Some connection cables contain resistors. Do not use cables that incorporate resistors for connecting to this unit. The use of such cables can cause the sound level to be extremely low, or impossible to hear. For information on cable specifications, contact the manufacturer of the cable.

921

• To prevent malfunction and/or damage to speakers or other devices, always turn down the volume, and turn off the power on all devices before making any connections.

• Wrap the power cord around the cord hook when transporting or storing the unit.

Main Features

The D-BASS 210 and 115 are powerful yet lightweight professional bass amps, which utilize Roland’s FFP technology incorporating new Active Speaker Control. The D-BASS 115X is a powered extension speaker.

Stacking the D-BASS 210/115 and the D-BASS 115X lets you create an even more powerful system.

D-BASS 210/115/115X Shared Features

High-Power, Multi-Amp Configuration................................................................

The D-BASS features a multi-amp arrangement with each speaker unit driven by its own dedicated power amp. Combined with signal processing optimized for each unit’s particular frequency response, this drives each of the speakers in the ideal manner.

D-BASS 115 D-BASS 115X

Thorough Weight Reduction ...............................................................................

• Newly developed custom speakers make use of new materials, succeeding in cutting the weight of previous models by half for the 10” speaker and one-third for the 15” speaker (as compared with previous Roland products). Moreover, stronger magnetic force ensures quick response with effective damping in the lower frequencies.

Advanced FFP Technology Incorporating Active Speaker Control.........................

115X 210/115

• These units employ Roland’s proprietary FFP amp technology for dynamic, powerful sound that exceeds specs, while D-BASS’s incorporation of Active Speaker Control technology realizes even higher quality sound.

• Active Speaker Control uses an optical sensor to monitor the movement of the speaker and correct discrepancies between the original sound and the speaker motion. This results in faithful reproduction of the Instrument's original sound characteristics and the nuances produced in performance.

FFP (Feed Forward Processing) is system control

technology that optimizes the performance of the amp, speakers, and cabinet characteristics according to the signals being input, based on the results of analyses of the operation and behavior of each section of existing amp systems.

Power Amp

Speaker

Speaker motion monitored

• Use of D-Class power amps and switching power supplies for high energy conversion efficiency reduces generation of unnecessary heat. This permits use of smaller, lighter power transformers and heat sinks.

• New cabinet designs make use of new materials and reduce unwanted vibration, resulting in cabinets that are lighter overall, yet still ensure ample ruggedness.

Active Speaker Control

● Conventional Bass Amps

With conventional bass amps, input signals are amplified by the power amp, and then the sound is output by means of the vibration of the speaker, but discrepancies occur between the signals output from the power amp and the actual vibration of the speaker. Observations of speaker motion when bass sounds are played reveal delayed response in the attack and release and superfluous vibration. Such discrepancies stem from the basic mechanical properties of the cone speaker construction, and are especially noticeable in the low-frequency range. These discrepancies result in a loss of clarity and definition in the bass sound.

● How Active Speaker Control Works

With Active Speaker Control, the speaker movement is monitored in real time with an optical sensor to detect any deviation from the input signal. Any such discrepancies are corrected by a digital signal processor, thus controlling speaker motion to reproduce the input signal as closely as possible.

● Effect of Active Speaker Control

Active Speaker Control affects the actual bass sound in the following ways.

• Speaker amplitude linearity is improved, producing a tight, powerful sound with better contour. In particular, this technology provides faithful reproduction of the low end for basses with Low-B string.

• This allows the range of frequencies reproduced to be extended further in the low end, expanding the frequency range of the bass sound.

• The speakers are drives in a way that creates a sound truer to the input signal, providing with greater responsiveness.
