dbx - '286S'
Microphone Pre-Amp Processor
sonically pristine foreverThe dbx® 286s is a Channel Strip Processor packed with features that offers studio quality microphone/instrument preamplifier and four processors that can be used separately or in any combination. The sonically pristine dbx 286s Mic Preamp has all the features you need, such as wide-ranging input gain control, switchable +48V phantom power, and an 80Hz high-pass filter to eliminate low frequency hum, rumble or wind. The patented dbx OverEasy® compressor can be used to transparently smooth out uneven acoustic tracks or add that classic "in your face" vocal performance that only a dbx compressor is capable of.
Use the frequency tunable De-Esser to remove vocal sibilance and high frequency distortion from instruments like cymbals. Fine-tune the Enhancer HF Detail control to add clarity and detail to your tracks and adjust the LF Detail control to add fullness and depth to vocals and bass instruments whilst reducing the muddy low midrange frequencies. The separate threshold and ratio controls on the Expander/Gate allow you to subtly reduce headphone leakage or radically gate noisy guitar amps.
Amazing Features
• Frequency tunable De-Esser reduces sibilance and high frequency distortion
• Enhancer increases the detail and definition of the high and low frequencies
• Classic dbx Compression puts great sound within easy reach
• Insert jack allows you to add an external processor
• Program adaptive Expander/Gate
Sound Your Best!
Effective ProcessingThe dbx 286s is fully compliment of metering and status LEDs to visually guide you to getting the sound you need. The floating balanced XLR Mic Input accepts balanced or unbalanced inputs to connect easily 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, like an EQ or delay unit or alternatively mix the Mic Preamp's signal out to an external destination. The price and trouble of patching together multiple processors for use on one track can be irritating. The dbx 286s gives you all the mic processing you need in one box, with the shortest, clearest signal path so your music can continue to sound its best.
