Revelation – Archival Phono Preamplifiers
Old & New Record EQ—Made Easy!
The Revelations will make it easy for you to archive older records.
As well as being a stereo RIAA preamp there are settings for other types of record, so rather than guessing the tonal balance, the Revelations have all the EQ settings you should need arranged on a three switch front-panel matrix.
Each one is supplied with an Old Record EQ information sheet, and more information on old record EQ can be found here.
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.

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.
