Roland DBASS-115X Roland D-Bass-115X Amplifier Roland DBASS-115X Overview 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&trade 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. Connect the D-BASS 115X to D-BASS 210/115 to create an even more powerful system. The speaker is designed to allow a D-BASS 210/115 to be set (stacked) on top of it. Built with FFP with Active Speaker Control technology for super high-quality sound, power, and efficiency. FULL RANGE and SUB WOOFER Modes The D-BASS 115X can also be used effectively as an expansion speaker with other small bass amps. Roland DBASS-115X Features: Ultra lightweight, powered bass speaker cab 300W RMS into 1 x 15" and tweeter Switch for full range or Sub functions Perfect match for D-Bass 115 or 210 Can be used as external cab with other amps Roland DBASS-115X Details: 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. 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. 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
