Introduction
Main Features
- Thanks to FFP technology, this DSP (Digital Signal
Processing) bass amplifier offers superior performance
regardless of its compact and lightweight body.
- Benefits of FFP Technology
1) FFP technology makes it possible to achieve dynamic,
high-powered sound that surpasses the output spec.
The Power Injection indicator allows you to monitor
the effect.
2) Although the cabinet is compact, the unit is able to
deliver a truly powerful low end, far out of proportion
to its 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.

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.

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-700
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
MANUAL button
to make the indicator
light up.
The factory-default control settings are stored in memory A
and memory B (p. 13). 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.
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.
