Product Details

dbx 286s Mic Preamp / Channel Strip Processor

Why mic up vocals and instruments through a noisy, blurry mixer when you can chose the dbx® 286s that delivers a studio quality microphone/instrument preamplifier. It's a full featured channel strip processor with four processors that can be used independently or in any combination. The 286s Mic Preamp has all the features you need, including wide-ranging input gain control, switchable +48V phantom power, and an 80 Hz high-pass filter to remove low frequency hum, rumble or wind. Use the patented dbx OverEasy® compressor to transparently smooth out uneven acoustic tracks or deliver that classic "in your face" vocal performance that only a dbx compressor can. Eliminate vocal sibilance and high frequency distortion from instruments such as cymbals with the frequency tunable De-Esser. Fine-tune the Enhancer HF Detail control to add sparkle and crispness to your tracks and make adjustments to the LF Detail control to add fullness and depth to vocals and bass instruments while cleaning up the muddy low midrange frequencies. And, the separate threshold and ratio controls on the Expander/Gate allow you to subtly reduce headphone leakage or radically gate noisy guitar amps.

dbx 286s status LEDs visually guide you to achieve the right sound. The floating balanced XLR Mic Input accepts balanced or unbalanced inputs to easily connect to professional and home studio microphones. The additional 1/4" TRS Line Input can accept balanced/unbalanced signals to process live electronic instruments or pre-recorded tracks at mixdown. Use the Insert jack to interface between the Mic Preamp and the signal processing sections to "loop out" to external processors (such as EQ or delay unit) 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 286s provides you with all the mic processing you need in one box, with the shortest, cleanest signal path to keep your music sounding its best!
