dbx 286s Microphone Preamp Processor provides concise and intuitive controls for all your mic processing needs, whether you use a microphone to record vocals and acoustic instruments, sample acoustic sounds, or for a public address system installation. The 286s also provides effective processing for electronic instruments, individual mixer tracks, and other mono sound sources.
The dbx 286s features wide-ranging input gain control, switchable +48V phantom power, and an 80Hz high-pass filter to remove low frequency hum, rumble or wind. The dbx OverEasy compressor can transparently smooth out uneven acoustic tracks, or deliver the classic “in your face” vocal performance. Vocal sibilance can be tamed or even eliminated and high frequency distortion removed from instruments such as cymbals with the frequency tunable De-Esser.
You can 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.
