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.

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 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.
