Graham Slee Revelation C RIAA/78/multi-EQ phono preamp for MC cartridges

REVELATION C RIAA/78/MULTI-EQ PHONO PREAMP FOR MC CARTRIDGES

The Revelation C phono stage is the multi-format variant of the Reflex C phono preamp — there is no difference except the additional record EQ switching.

The Revelation C is a hand-crafted state-of-the-art solid state stereo phono preamp suitable for use with moving coil phono cartridges and designed to deliver pinnacle performance for playing modern LPs, older recordings and 78s. The input impedance is 100 ohms.

It's amazing how the Revelation C can make early LPs and 78 rpm records sound as tonally balanced and fresh as some of today's modern vinyl records. Three 3-way switches provide a matrix of equalization curves covering virtually all electric phonograph records ever released, including today's modern RIAA pressings. The equalization settings let you hear the original material exactly as it was recorded and equalized in the grooves.

For the Revelation C Equalization curves see Record Equalisation Curves.
