DBX 386 双通道电子管话放
DBX 386
高阻抗，4 / 1“仪器输入位于前面板，以及麦克风/线路开关，和20分贝垫显示我们的奉献，提供方便的工作室。12段为一眼就可提供一个模拟或数字水平的视觉指示。
银系列386双通道麦克风前置放大器提出两全其美的替代真空管的温暖与专有的dbx®IV型™转换系统结合成一个实惠的套餐。386有许多相同的功能，其他产品在银系列，如+48V幻象电源，相位反转开关，和低切滤波；也包括两AES/EBU数字输出，以及S/PDIF格式。
高阻抗，4 / 1“仪器输入位于前面板，以及麦克风/线路开关，和20分贝垫显示我们的奉献，提供方便的工作室。12段为一眼就可提供一个模拟或数字水平的视觉指示。后面板包括麦克风和线路输入和输出，字时钟同步输入和输出，和数字输出。添加可选采样率44.1 kHz，48 kHz，88.2 kHz，或96千赫；可选的抖动和噪声整形；和独立的模拟和数字输出控制，这已经令人印象深刻的功能列表，我们认为你会同意386辜负创新dbx®标准。
推荐：工作室。

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; but also includes digital outputs in both AES/EBU, and S/PDIF bats.
The high impedance, 1/4" instrument b 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 bs and outputs, word clock sync b 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 we think you’ll agree that the 386 lives up to the innovative dbx® standards.
Recommended for: Studio.
