dbx 286A Description
The dbx® 286A's Mic Preamp and Five processors can be used independently or in
any combination. Why mic up vocals and instruments through a noisy, blurry
mixer? The dbx 286A's sonically pristine Mic Preamp has all the features you
need, including wide-ranging input gain control, switchable 48V phantom power
and an 80Hz high-pass filter. Use the 286A's newly designed and patented
OverEasy® Compressor to transparently smooth out uneven acoustic tracks or
deliver that classic "in your face" rock vocal. Take out vocal
sibilance and high frequency distortion in cymbals with the 286A's frequency
tunable De-Esser. Fine-tune the Enhancer's HF Detail control to add sparkle and
crispness to tracks. LF Detail control adds fullness and depth to vocals and
bass instruments while simultaneously cleaning up muddy low midrange
frequencies. And, the Expander/Gate's separate threshold and ratio controls
allow you to subtly reduce headphone leakage or radically gate noisy guitar
amps.
The dbx® 286A's full complement of metering and status LEDs visually guide you
to achieving the right sound. The floating balanced XLR mic input accepts
balanced or unbalanced inputs. An additional 14" TRS phone jack can accept
balanced/ unbalanced line signals to process live electronic instruments or
pre-recorded tracks at mixdown. An insert jack between the 286A's Mic Preamp
and signal processing sections can be used to "loop out" to external
processors (such as EQ) or to mix the Mic Preamp's signal out to an external
destination.
The cost and hassle of patching together multiple processors for use on one
track can be frustrating. The dbx® 286A gives you all the tools you'll need in
one box, with the shortest signal path to help keep your music sounding clean.
