BX-220H / BX-2115 ThunderBass Amplifier

Introduction:

Crate’s new BX-220H/BX-2115 ThunderBass amplifiers are feature-packed, professional-strength powerhouses which can deliver incredible bass sounds. Rugged construction, reliable American craftsmanship and solid state electronics add up to create one very roadworthy, stage-ready piece of gear.

The BX-220H packs solid performance into a compact head unit, contained in a rugged Tolex® covered cabinet. Its side-mounted handle and heavy-duty rubber feet on two sides (not just the bottom, but also on the end you set it down on in real life) increase its value to those musicians who are always “on the go.” The BX-2115 combines the same great bass amp with an equally outstanding 15” ThunderBass American-made transducer for a small but hard-hitting combo amp suitable for the club, small hall or recording studio. An optional JBL 15” bass transducer is also available (BX-2115L).

Both amplifiers will deliver 220 watts into 4 ohms, or 150 watts into 8 ohms. A listing of the features of these amps is given below.

Features:

Additional information can be found on the pages indicated.

•Solid state circuitry for reliable service and incredible tones.

•Crate’s APM (Automatic Power Maximizer) limiter circuit for the most output without distortion.

•Balanced line out with adjustable level control and “pre/post” switch (pages 4 and 5).

•Headphone jack with adjustable level control for private practice sessions (page 4).

•Effects loop for noiseless use of your favorite processors and effects (page 5).
