286S dbx Microphone Pre-amp Processor

dbx 286S

The dbx 286s is a complete Channel Strip processor that provides one preamplifier for studio-quality microphones/studio equipment and four processors that can be used independently or in any combination.  The dbx 286s microphone preamplifier has all the features you need, including broad-spectrum input gain control, switchable +48V phantom power supply, and an 80Hz 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 provide the classic "in-face" vocal performance that only a dbx compressor can deliver.

How To Measure Your Bust

With your arms relaxed at your sides, measure around the fullest part of your chest.

How To Measure Your Waist

Measure around the narrowest part of your natural waist, generally around the belly button. To ensure a comfortable fit, keep one finger between the measuring tape and your body.

286S DBX

The dbx 286s offers a complete complement of measurement and status LEDs to visually guide you to the right sound. The floating balanced XLR microphone input accepts balanced or unbalanced inputs for easy connection to professional microphones and home studios. 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 the mic preamp and signal processing sections to loop out to external processors (such as the EQ or delay unit) or to mix the mic preamp signal to an external destination. 

The cost and hassle of putting multiple processors together for use on one track can be frustrating. The dbx 286s gives you all the mic processing you need in one box, with the shortest, cleanest signal path to make your music sound its best!
