Crate Amplifiers BX-4115 Stereo Amplifier User Manual


 
Introduction:
Crate’s new BX-440H/BX-4115 ThunderBass amplifiers are feature-packed, professional strength power-
houses which can deliver incredible bass sounds. Rugged construction, reliable American craftsmanship and
solid state electronics add up to create very roadworthy, stage-ready gear.
The BX-440H 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 increase its value to those musi-
cians who are always “on the go.” The BX-4115 combines the same great bass amp with an equally out-
standing 15” ThunderBass American-made transducer for a small but hard hitting combo amp suitable for
the club, small hall or recording studio.
Both amplifiers will deliver 440 watts into 4 ohms, or 250 watts into 8 ohms. A listing of the features of
these amps is given below.
