New-Generation Amps for Better Bass

Bass amp technology takes a big stride forward with the new D-Bass series. Roland’s newest and most advanced bass amplifiers employ proprietary FFP with Active Speaker Control technology for lightning-fast response and ultra high-quality bass tone. Two combo-type models (210 and 115) offer different wattages and speaker configurations to accommodate a variety of needs and tastes. A powered extension speaker (model 115X) adds another layer of punch for performers who play larger venues.

  • - Built with FFP with Active Speaker Control technology for super high-quality sound, power, and efficiency
  • - COSM preamp models, including Modern, Vintage, and Super Flat
  • - Tube Logic function produces the fat and natural compression of tube amps
  • - 4-band EQ with dedicated Tweeter Control knob
  • - Passive/active input and dedicated piezo input also built in — Perfect for any type of bass sounds
  • - Rock-solid construction, but lighter overall weight to ease the burden of transportation
  • - High-performance neodymium-based speaker
  • - Matching 115X powered satellite cabinet provides 300 watts of extra power and punch — looks great too!

FFP Upgraded with Active Speaker Control

To achieve their high-quality sound and amazing performance, the new D-Bass amps employ breakthrough Roland technology: FFP incorporating Active Speaker Control. FFP (Feed Forward Processing) is a DSP-based process that analyzes incoming signal and maximizes it before it hits the speaker. By utilizing Active Speaker Control, FFP allows the D-BASS to faithfully reproduce the incoming signal of the original bass, thereby controlling its speaker movement to reproduce the same input signal as closely as possible. This “true input matching” technology allows lower string sounds to be much clearer, and the overall feel to be more direct than with other bass amplifiers. A technology exclusive to Roland amps, FFP provides a marked increase in speaker efficiency, loudness boost, and overall perceived power.

COSM Preamps

Equipped with Vintage, Modern, and Super Flat COSM preamp models, the D-Bass 210 and 115’s COSM preamps can deliver a range of great tones beyond that of a traditional analog bass amp. With the simple, analog-style controls, you can control your sound quickly and easily. Roland’s unique “Super Flat” setting reproduces the bass guitar’s original sound characteristic without coloration. Its fat and clear characteristic is also perfect for the piezo sound of upright bass. Detailed sound adjustments are possible with the 4-band EQ, including a dedicated Tweeter Control knob.

Two Compression Types

Both 210 and 115 D-Bass amps are equipped with a pro quality solid-state compression, plus a Tube Logic section. Derived from Roland’s BluesCUBE, the newly improved Tube Logic produces the type of fat and natural compression associated with vintage tube amps. No matter how razor-sharp the tone, Tube Logic can dunk it in a liquid-warm bath.

Satellite Power

Need more beef? Add a D-Bass 115X powered speaker cab. Designed to be a perfect match electronically and physically for the D-Bass 210 or 115, the 115X provides 300 crushing watts of add-on power for the extra volume and punch required by larger venues and stages. The 115X has a switch for Full Range or Sub Woofer mode, affording players the flexibility they need to maximize their rigs from stage to stage.

Speaker/Amp Synergy

The D-Bass has multiple power amps: a separate amp for each speaker. This enables
maximum performance and sound quality from each speaker.

Power Supply

A key benefit of Roland’s D-Bass is its high power, light weight, and high efficiency with very little heat. (Most power amps produce a lot of heat.) Thanks to its sophisticated switching power supply, the D-Bass doesn’t require the typical bulky, heavy transformer found in most amps.

Improved Cabinet

Roland’s decades of expertise in amp design has culminated in a new-breed cabinet that’s strong, lightweight, and devoid of unnecessary vibration.

Neodymium Advantage

Equipped with high-grade neodymium speaker magnets, each new D-Bass amp delivers amazing performance without the weight associated with traditional speaker design.

Road Tough, Light Weight

Don’t let their lighter-than-average weight fool you. These amps are tough as nails and built for the road. Equipped with high-performance/low-weight neodymium speaker magnets, each new D-Bass amp is a performance powerhouse that’s a joy to transport. Industrial-strength, smooth-rolling casters make the job of getting from gig A to B even easier.
