DIGITAL DYNAMICS DDP PROCESSOR ® Dual Vacuum Tube Preamp 386 w/Digital Out The Silver Series 386 dual channel tube mic preamp puts the best of both worlds into one 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. In addition, the 386 also offers digi- tal output capabilities in both AES/EBU, and S/PDIF formats as standard features. The high impedance, 1/4" instrument input located on the front panel, as well as the mic/line switch, and 20 dB pad show our 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, insertion jack and digital outputs. Add selec- table 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 we think you’ll agree that the 386 lives up to the uncompromising standards of dbx Professional Products.
