Graham Slee Revelation C - MC Phono Stage Preamplifier

• Each one is supplied with an Old Record EQ information sheet, and more information on old record EQ can be found on the Graham Slee website
• There's a model for high output cartridges - the Revelation M; and a model for low output moving coil - the Revelation C.
• The Revelation M is available with either the basic ("green energy") power supply or the PSU1 power supply for improved sonics. The Revelation C is supplied with the PSU1 power supply only. Both models are fitted as standard with a rear panel mono-switch.
• Basic power supply
• PSU1 power supply - recommended for best results
• Sharing similarities with our Jazz Club archival phono preamp, the Revelation phono preamps use the more advanced circuit techniques of our Reflex M hi-fi RIAA preamplifier and Reflex C phono preamps.
• Pre-set Equalisation for Repeatable Results
• Our research into the equalisation required for numerous old record labels makes it easy for you to select the most suitable tonal balance time after time.
• Being arranged as presets on front panel switches, the guesswork of variable controls is taken away, leading to repeatable results.
• The different EQ settings will allow you to obtain a good tonal match to what the the original sound would have been on 78 rpm records, vinyl LPs and EPs
• There is also an RIAA setting for modern stereo vinyl records, which makes it a significant stereo RIAA preamplifier.
• The Revelations are suitable for professional archiving use as well as private use where you want the option to play and archive records from different eras.
• Revelation M
• The Revelation M stereo RIAA stage is for high output cartridges of the moving magnet, high output moving coil and high output moving iron varieties.
• Based on the Reflex M hi-fi RIAA preamp, it is optimised for these high output cartridges - its input stage having more than adequate dynamic headroom to be able to accept the largest signal peaks.
• By "dynamic" we mean it can handle peaks without slew-induced distortion, and transients whether musical or due to surface imperfections, do not get "slew-distorted". This is an important factor which means archival copies will retain more of the original detail with fewer distortion artifacts.
• Revelation C
• The Revelation C was designed for archivists with a preference for low-output moving coil cartridges, and is based on the Reflex C hi-fi RIAA stage moving coil phono preamp.
• Power Supplies
• For best results we recommend you choose the PSU1 power supply option for the Revelation M. It is otherwise available with the basic power supply which is low-energy and is suitable where equipment has to comply with low-carbon targets. The Revelation C is only supplied with the PSU1.
