Solid hardware for sound improvement

A great product to help make me sound great.

By CURTIS S.

This is a great product. I really recommend it.

Become a master of sound with the dbx 286s Mic Preamp/Channel Strip Processor, a high-quality, professional-grade audio equipment piece from the reputable brand, dbx. This versatile and reliable studio preamplifier is designed to deliver studio-quality microphone and instrument preamplification, along with four independent or combinable processors.

Why settle for a noisy, blurry mixer when you can achieve pristine sound clarity with the dbx 286s Mic Preamp This device is equipped with a wide-ranging input gain control, switchable +48V phantom power, and an 80Hz high-pass filter, designed to eliminate low-frequency hum, rumble, or wind, ensuring a clean, clear audio output.

Experience the patented dbx OverEasy compressor, capable of smoothing out uneven acoustic tracks or delivering that classic, powerful vocal performance unique to a dbx compressor. The frequency-tunable De-Esser works to eliminate vocal sibilance and high-frequency distortion from instruments like cymbals, ensuring a smooth, balanced sound.

The Enhancer HF Detail control allows you to fine-tune your sound, adding sparkle and crispness to your tracks. The LF Detail control adds fullness and depth to vocals and bass instruments, cleaning up muddy low midrange frequencies for a more refined sound.

The dbx 286s also features separate threshold and ratio controls on the Expander/Gate, allowing you to subtly reduce headphone leakage or radically gate noisy guitar amps. A full complement of metering and status LEDs guide you visually to achieve the perfect sound.

The floating balanced XLR Mic Input accepts both balanced and unbalanced inputs, making it easy to connect to professional and home studio microphones. The additional 1/4" TRS Line Input can process live electronic instruments or pre-recorded tracks at mixdown. The Insert jack provides an interface between the Mic Preamp and the signal processing sections, allowing you to "loop out" to external processors or mix the Mic Preamp's signal out to an external destination.

Say goodbye to the cost and hassle of patching together multiple processors for use on one track. The dbx 286s provides all the mic-processing you need in one box, ensuring the shortest, cleanest signal path to keep your music sounding its absolute best.
