Each amp stage is individually optimized for peak performance using detailed Electrodyne factory engineering notes and select high performance components identical to the originals. In fact, the 501’s transformers are made by Electrodyne’s original supplier to exacting factory specifications.\u003c\/p\u003e \u003cbr\u003e The new preamp’s active DI circuit presents an almost immeasurable load (over six megohms!) to sensitive musical instrument outputs allowing incredibly accurate capture of the instrument’s true tone. Furthermore, the output of the DI circuit is designed to directly connect and interact with the mic input transformer to permit an extremely broad spectrum of tonal options. \u003cbr\u003e \u003cbr\u003e The faceplate of the Electrodyne 501 features a large rotary gain control offering up to 68dB of gain – adjustable over 50dB in 2dB steps with two ranges via a 20dB pad switch – and a smaller output level pot infinitely adjustable from 0 (off) to +6dB over unity. Additional switches for impedance selection (50 or 200 ohms), phase reverse, +48V phantom power and DI (with 1\/4\" input jack) are also present, as well as a clip LED that monitors all three amp stages and illuminates when any stage is 3dB from clipping.\u003cbr\u003e\u003cbr\u003e\u003cspan style=\"font-weight: bold;\"\u003eSpecifications\u003c\/span\u003e\u003cbr\u003e\u003cul\u003e\n\u003cli\u003eMaximum Gain: 68db.
