Linear Dynamic Range Enhancer (1981)
The 2BX provides up to a 50% increase in stereo dynamic range, but with one important
difference to the 1BX - It divides the frequency spectrum into two bands, and treats each separately.
That's especially important with music of a strongly percussive nature. By separating the lower frequencies, the 2BX doesn't allow the bass or kick drum to influence the vocals or midrange
instruments. The 2BX has two separate 10-LED displays - one for each band.
Both the 1BX and the 2BX have a number of important features in common with the 3BX. Their release time is program-dependent, not fixed, resulting in smooth action that does not alter the character of the music as dynamics are expanded and noise is lowered.
By reacting appropriately to different kinds of sounds, the 2BX preserve the naturalness of any given sound.
It is a true stereo expander that maintains rock-solid stereo imaging, unlike some other stereo expanders on the market.
All DBX linear expanders have a pleasant side benefit - up to 20dB of noise reduction. There isn't a stereo system around that won't be improved by one of this family of DBX expanders.
