A NOTE FROM THE MANUFACTURER
Recording engineers and serious record collectors know the problem when playing early phonograph re-
cords: ordinary RIAA phono equalization does not always match the original recording equalization that was
used to make the record.
78rpmrecordsinparticularhavemanydifferenteqsettingsdependingonperiod,placement,andrecording

Because I have not been able to buy a phono preamp which can provide the correct eq settings of 78s and
earlyEP/LPs,IhavedesignedtheVADLYDMD12MK4incooperationwithBjarneJelsborg,BJElektronik,

ABOUT PHONO PREAMPLIFIERS
Whenplayingphonographrecords,youmightnormallyusethephonoinputprovidedonyouramplier,
often called a RIAA (Recording Industries Association in America) phono input.
TheRIAAequalizationcurvespeciestwoturnoverpoints(a‘turnover’pointiswherethelevelchanges
±3dB):oneat500Hz,andtheotherat2125Hz.TheRIAAplaybackcurvehasthefollowingtheoretical
response:
1.+17dBfrom20Hzto50Hz,thenfallingabout6dB/octaveto
2.0dBfrom500Hzto2125Hz,andthenfallingagainabout6dB/octaveto
3. -13.7dB at 10kHz.
You use the RIAA playback curve to compensate for the RIAA equalization that was originally used to make
the record.
Normallythisworkswellonsingle,EPandLPrecords,issuedfrom1955andlater.ButwithearlierLPs
(somerecordcompaniesdidn’tuseRIAAbefore1960),thiscurveisnotcorrect.
The cutting equalizations on all 78 RPMs and LPs before 1955 have been very different. 78rpm records
inparticularusedcurvesverydifferentfromtheRIAAcurve.Forthisreason,youshouldnotusetheRIAA

I want to thank Roger Wilmut for basic information about reproduction of 78rpm records. For a better un-
derstandingoftheproblemsofreproductionofrecords,readthefollowingarticles(withafeweditsfrommy
hand) taken with kind permission from Roger Wilmuts home page: ”Reproduction of 78rpm records” - www.
rfwilmut.clara.net/repro78/repro.html.
EQUALIZATION OF PHONOGRAPH RECORDS

stylusmovesandengravesagrooveintheblankdisk.(Thereisofcoursealotmoretoitthanthat,butwe
are considering only the basics here.)
However,becausethecutterhead’smovementstranslatetheamplitudeswingsoftheoriginalsignalinto
velocity - the rate at which the stylus moves during its swings - low-frequency signals would be recorded
with a much larger swing than high-frequency signals of the same original amplitude. In order to keep the
movements of the groove much the same at all frequencies (given equal level signals) it is necessary to
useacircuittointroduce-inthetheoreticalsituation-a6dB/octavecutasthefrequencydecreases-i.e.,
halve the frequency and you halve the voltage.
Inthereversesituation,thatofareproductionhead,theprincipalisthatofawiremovedinamagneticeld

motor,whereincreasedvoltagemeansincreasedspeed.Therefore,theconstantamplitudegroovetheo-
retically achieved produces a signal where the bass is low and the treble high: so a 6 dB/octave cut with
increasing frequency would be called for.
Intherealworld,lossesintheheadwithincreasedfrequencycomplicatetheissue.Earlycutterheads

Tocompensateforthis,theplaybackcharacteristicboostedthebassbelow200Hzbutleftitatabovethat

Boosting the treble during recording had the effect of reducing the surface noise during playback. It was
alsocommontoattenoutthebassattheverylowestfrequenciestoreducetheboostofrumblefromthe

Use of the correct eq curves when reproducing 78rpm records produces a startling improvement in the
sound quality (although admittedly the surface noise can increase).
Many of these older recordings are of surprisingly high quality after all!

This enables them to track movements in the groove more easily (as the groove moves from side to side it

The illustrations below could apply equally to a spherical tip and an elliptical tip seen from the front: in prac-

(Somemodernmicrogroovestylihaveaatsectionatthecontactpoint,
giving a wider area of contact which reduces wear: however it can also
increase noise from worn or damaged groove walls and I would be dubious
about its use for 78s).

HOW TO USE THE PREAMPLIFIER
Front Panel (left to right)
• Use the pushbutton on the extreme left to select either Phono Input 1 or Phono Input 2.
• The next two pushbuttons select either MM (moving magnet) or MC (moving coil) cartridges for each
input.AnLEDlightswhenMCisengaged,inwhichcaseloadimpedancesof50,100,or200Ohmscan
be selected using the appropriate toggle switch above each pushbutton.
• Equalizationcurvesareselectedwiththerotaryswitch,andthecurrentlyactivecurveisindicatedbythe
appropriate LED. Always change equalization curves slowly to minimize pops (the unit was designed to
completely eliminate annoying pops by switching slowly).
• Both the 80 Hz Low Cut Filter and the High Cut Filter (which is continuously variable from 1.6 kHz to
12kHz)areengagedbypressingindividualpushbuttonswitches,whichcausestheappropriateLEDto

Generally,thereisadifferencebetweenAmericanandEuropean78rpmrecordings:theAmericanrecords
were normally much louder cut with much more bass response and a higher bass turnover frequency. The
two American record companies Columbia and Victor had different settings but both used basically the pat-
ent from Western Electric.

Columbia is an American Columbia setting used by Columbia since around 1930. But note: this setting is an
ideal setting and only useful for records in absolute good condition
.
BSI 78 useful for all post 1953 78s. It can also be useful for some earlier American 78s.

recordingswereverticallycut,alsonamedas”hillanddale”recordings.Becauseofthat,amonocartridge
is not able to reproduce a vertical groove signal. But a stereo record is a combination of a lateral cut and
