    dbx 386 Dual Vacuum Tube Microphone Preamp with Digital Out Product Description

    The Silver Series 386 dual channel tube mic preamp puts the best of both worlds into 1 affordable package by combining the warmth of the irreplaceable vacuum tube with the proprietary dbx Type IV conversion system. The 386 boasts many of the same features as other products in the Silver Series, such as +48V phantom power, a phase invert switch, and low cut filtering; but also includes digital outputs in both AES/EBU, and S/PDIF formats.

    The high impedance, 1/4 in" instrument input located on the front panel, as well as the mic/line switch, and 20 dB pad show dbx's dedication to providing convenience in the studio. The 12 segment LED meters provide a visual indication of analog or digital levels at a glance. The rear panel includes both mic and line inputs and outputs, word clock sync input and output, and digital outputs. Add selectable sampling rates of 44.1 kHz, 48 kHz, 88.2 kHz, or 96 kHz; selectable dithering and noise shaping; and separate analog and digital output controls to this already impressive list of features, and you'll agree that the 386 lives up to the innovative dbx standards.

    About dbx

    More than 25 years ago, a brilliant young engineer named David Blackmer sat at his workbench trying to find something that would make music easier to record. What he came up with changed everything that was known about dynamics processing at the time. Enter the VCA. With the launch of the dbx 160, the music industry sat up and took notice of the new company with the 3 lower-case initials: dbx. Further refinements brought new processes and new products. The 165 a few years later would prove another turning point. The advent of OverEasy compression defined the process of threshold sensitive compression. Both the 160 and 165 are still greatly sought after standards that come along all too infrequently. The 160 is now worth many times its original price tag in the used market - if you can find one. The 165A has proved so popular that it is still manufactured today, exactly the same way it was 20 years ago; pretty rare in this industry.

    dbx Professional Products are done for you -- the lunch box, working class musicians, the weekend wedding band, the Grammy-winning engineer, the mega-star, the guys who make music just for the heck of it in the garage in February, the newly aspiring producer of the month. You endure the uncharitable business of music and carve a life of unusual reward from the ever-challenging industry. It is this heritage, spirit, and character that inspires musicians and every product dbx makes.
