Introduction

Main Features

- Delivering unsurpassed performance thanks to newly

developed FFP technology, this compact, lightweight,

high-power bass amplifier incorporates a DSP (Digital

Signal Processor).

- Benefits of FFP Technology

1) You can obtain dynamic, spec-exceeding high-power

sound, even with an output of 160 W. You can monitor

the effects with the power injection indicator.

2) Despite the compact cabinet, it’s possible to play heavy

bass that surpasses the amp’s small physical size.

3) You can obtain clear sound with excellent response.

- You can store the settings for controls in memory A or

memory B (Memory feature). It’s also possible to call up

the contents of memory with a foot switch. This means

you can also change amp settings quickly during live

performances.

- The amplifier section employs COSM technology, which

uses modeling to re-create sound characteristics

originating in differences in amplification systems and

circuit design. This makes it possible for you to obtain

everything from high-response, wide-ranging sounds to

overdriven sounds. The Compression feature even

replicates the unique compression characteristics of amps

through modeling.

- The amp is equipped with a three-band equalizer offering

easy operability. Because the midrange-band frequencies

can be changed, you can create a wide range of sounds.

You can also use it in combination with the Shape switch

to obtain a rich variety of sounds.

- This amp features a newly developed D-chorus that has

been specially tuned for bass. Dynamic band-division

processing is performed as appropriate for the input

signal, to produce a great chorus effect that does not

impair the low-frequency response even when you use

"slap" playing techniques or when you play harmonics.

- The input and output connectors include a headphones

jack with optimized tonal correction, a high-performance

XLR-type DI connector, two types of Line Out jacks (an

XLR type and a balanced phone jack), and convenient

Insert jacks for connecting external effects units or other

equipment, thus providing support for a wide variety of

applications.

MEMO

What’s FFP (Feed Forward Processing) Technology?

FFP is innovative technology from Roland that predicts how

to obtain optimal operation for the amplifier, cabinet,

speaker, and respective input signals that make up the bass

amp system. By performing signal processing based on these

predictions, it obtains maximum performance from each of

these components.

MEMO

What’s COSM (Composite Object Sound Modeling)

Technology?

Technology that uses different means to create a virtual

reconstruction of physical structures, materials, and so on

that actually exist is called modeling technology. COSM is

proprietary technology from Roland that combines several

kinds of sound-modeling technology to create even newer

sounds.

Before You Use the DB-500

When you want to use the amplifier like a conventional

analog amp or want to play sounds using the present control

settings, such as when you’ve adjusted the controls to new

settings, press the

light up.

The factory-default control settings are stored in memory A

and memory B (p. 11). When you switch on the power for the

first time after purchase, the sounds play according to the

settings in memory A, regardless of the present control

settings.

NOTE

After that, starting with the next time you turn on the

power, sounds are played with the settings in effect

when the power was last switched off. For instance, if

you turn off the power while the settings in memory A

are in effect, sounds are played using the settings in

memory A the next time you turn on the power.
