Beyond superb sound quality, the ADL 600 is special because of its flexibility and extensive features. Each of the two input channels has separate mic, line, and instrument inputs, and you can select among four mic-input impedances, so the preamp works great with any type of microphone. Each channel offers a balanced XLR line-level output. You get a highpass filter, +48V phantom power, polarity inversion, and a 20 dB pad, all controlled by big, sturdy, military-grade switches. Fast-acting, eight-segment LED meters accurately detect fast transients and peaks. Large, backlit analog VU meters display output levels, and a -6 dB switch lets you meter particularly hot signals. The ADL 600 is indeed full-featured£and then some. Technical explanations and descriptions of features are well and nice but when it comes to preamps, hearing is believing. So try the ADL 600 at your favorite PreSonus dealer and experience the thrill of using the worlds finest tube preamp.
