ELAC Alchemy PPA-2 Phono Preampliﬁer | www.elac.com | Page 4

Wiring the Inputs

Connecting a turntable to the PPA-2 Phono preamp

Phono 1 is Unbalanced only (RCA jacks), Phono 2 can be either Balanced (XLR jacks) or Unbalanced.

Cables from the turntable to the PPA-2 should be as far as possible from AC Mains cables wherever possible. If

they must cross, do so at right angles if you can.

Typically a balanced connection will be more immune to hum, so it would be the preferred connection.

However, you must be careful that the shell of the XLR is not connected directly to the ground line within the

XLR connector. They SHOULD be independent. The shell is the external shield of the cable and connector, and

should be the CHASSIS connection. The ground wire within the XLR is twisted with the (+) and (-) balanced and

should be the signal or tonearm ground. This can all be conﬁrmed with an Ohm meter.

Whichever style you choose, please use the very best cable you can in this location due to the very low signal

levels coming from your phono cartridge.

After you make your audio connections refer to Page 8 to correctly set the DIP switches.

ELAC Alchemy PPA-2 Phono Preampliﬁer | www.elac.com | Page 5

Wiring the Outputs

Connecting the PPA-2 to a Pre-Ampliﬁer, Receiver, or Integrated Ampliﬁer

The PPA-2 provides both Unbalanced (RCA jacks) and Balanced (XLR jacks) outputs. Typically a balanced

connection will be more immune to hum, so it would be the preferred connection. Again, please use the best

quality cables you can between PPA-2 and your control preampliﬁer.

ELAC Alchemy PPA-2 Phono Preampliﬁer | www.elac.com | Page 6

Grounding

Correctly grounding an audio system for minimum hum and maximum signal-to-noise ratio can be very

complicated, and will vary from system to system.

PPA-2 has two dierent ground posts, each at dierent ground potentials; SIGNAL and CHASSIS. SIGNAL is at

the ground potential of the input signal. CHASSIS is that of the AC Mains ground connection; typically used as a

shield.

If your turntable has only one ground connection, usually that will connect to CHASSIS. If you have a separate

ground wire from the arm it should go to the SIGNAL ground, and the turntable motor or body ground wire

should go to CHASSIS.

Initial Power On

After making all necessary audio and grounding connections. Plug the included power cord to an available wall

outlet.

Press the Power button to turn on the PPA-2.

At initial power on the PPA-2 will go through a brief warmup period during which it will be in mute. You will see

the Alchemy Series Logo on the front panel display as the unit warms up. The screen will go blank just before

PPA-2 unmutes and restores the last known status condition of all functions; INPUT 1 or 2, Filter, Gain and Mode.

This ﬁrst time it is powered on it will be on INPUT 1, no ﬁlter, low gain and in stereo.

Selecting Cartridge Type

There are several technologies of phono cartridge available. The PPA-2 works with Moving Magnet (“MM”) and

Moving Coil (“MC”) types. USUALLY MM cartridges are designed to operate into a nominal load impedance of

47K Ohms. MC cartridges are typically loaded with much lower values from 5 Ohms to a few hundred Ohms

up to maybe as much as 1000 Ohms. There are always exceptions to these rules, so check to be sure. The

PPA-2 lets you select this load precisely through use of a continuously adjustable potentiometer and built-in

measurement system. Please refer to ﬁgure 1 for the DIP switch settings to correctly select either the ﬁxed 47K

or adjustable load for Inputs 1 and 2 separately.

ELAC Alchemy PPA-2 Phono Preampliﬁer | www.elac.com | Page 7

Cartridge Load Measurement

If you need to set the adjustable load, ﬁrst look up the suggested loading for your particular cartridge model in

the manufacturers speciﬁcations. Also check a few of the known audio columnists to see what their reviews

might suggest for optimum loading. Sometimes one will ﬁnd a large discrepancy between these resources. The

PPA-2 makes it easy to test these various choices. A rough rule-of-thumb is that loading should be about 10

times the source impedance speciﬁcation for the cartridge. This, and suggestions from resources you might ﬁnd

will, in the end, just be guidelines. The beauty of the adjustment method PPA-2 uses is that you can adjust up

and down from the suggested starting points to achieve what sounds best for you in your system.

With PPA-2 powered ON and the appropriate input selected, press the SELECT button. PPA-2 screen will come

on and tell you that you have entered measurement mode and will show the current LEFT and RIGHT load

settings. Note that audio is muted during the measurement process.

Turn the load pots on the back panel associated with the input in question and you will see the readings on

the screen change. Set both the LEFT and RIGHT adjustment knobs to the desired loading. It’s a bit fussy

as the controls are quite sensitive, but with some patience you will get it to where you want to be. Pressing

the SELECT button again will switch to the exit screen where measurement mode will automatically exit in 15

seconds and put the display to sleep. To exit immediately, press SELECT again during the countdown.

To set the adjustable loading for the alternate input you must select that input and then enter measurement

mode again by pressing SELECT and following the instructions above.

ELAC Alchemy PPA-2 Phono Preampliﬁer | www.elac.com | Page 8

Settings and Adjustments

The PPA-2 has a row of LED status indicators followed by a row of buttons to control the indicated functions.

Please refer to Figure 2.

MUTE lights when the MUTE button is pressed. This feature is convenient when changing tracks or making

some kind of adjustment that could otherwise result in an objectionable noise. Press once to engage, again to

disengage.

1 & 2 refer to the Input numbers on the back of PPA-2. Pressing the INPUT 1 or INPUT 2 button toggles between

them. INPUT 1 is on the far left (as viewed from the back) and INPUT 2 is on the other side of the dip switches

(where you have already selected 47K or adjustable load, and if INPUT 2 is to be balanced or unbalanced, right?)

When lit indicates that the High Pass (i.e. rumble) ﬁlter has been selected with the HP button. Toggle to

switch. This mode is useful if your turntable has a bit of low frequency noise, or if the cut you are playing has so

much bass that is causes feedback from your turntable (sometimes known as howling.)

+18db Indicates when the PPA-2 is in high gain (MC) mode and is toggled by the MC/MM button and will

obviously be louder in the lit condition. Pick the position where you have sucient volume in your system to

play as loud as you need. There is no advantage to high gain mode if you don’t need it, it will only be noisier but

not sound any better.

L+R Indicates MONO mode and is toggled by the MONO button. Use mono when playing mono records or

when you are checking channel balance or some other test.

TWEAKING

As noted above, select the gain position you feel gives sucient volume range for your listening tastes. Don’t

use more gain than you need, there is no point.

Once you have sound and are starting to listen critically you should notice great dynamics from the PPA-2, as

well as extended range in both the bass and treble regions. Smoothness and dimensionality will be excellent,

but none of these will be as good as they will be after a week of warmup, perhaps even several weeks.

If you are using the adjustable load feature and you want to, you can start to make ﬁne adjustments to the load

for each channel to see if you like the sound better one way or the other. While valid now for better enjoyment

during the warmup period, ultimately you will want to make these same changes once the PPA-2 stabilizes as

they may be subtly dierent.

Note that for tweaking the load you do not enter measurement mode; to do so would mute the audio and you

need to be listening for this step. The idea is to put on a record with which you are very familiar and very slightly

increase the left and right loads and listen to the results. Then, reduce the load very slightly and listen again.

You might need to iterate this process a number of times till you feel you have gotten the best sound you can

achieve. At this point the actual load number has likely been altered from the original settings you made. If you

want, you can enter measurement mode and read the settings you have gotten to, for future reference.

MODE SELECTION

Other than gain, the PPA-2 has two modes you can select, as needed, to improve performance under certain

conditions; MONO and HP. Their purpose is described above. Each will be remembered as your preferred

setting upon power o, so be sure to disengage them when not needed.

Settings and Adjustments

TROUBLESHOOTING

No sound or low volume? Do you have the correct input selected? Do you need to be in High gain (+18db)

mode? Is your cartridge loading set so low that the cartridge is not producing enough output? Are you using

INPUT 2 RCA or XLR without switching the dip switches to the correct mode? Are you in MUTE?

Measured load not changing? Check that the DIP switch setting for 47K/Adjustable are in the Adjustable

position. Are you turning the correct knob for the Input you are measuring?

Acoustic Feedback causing howling? Switch on the High Pass ﬁlter.

Audible hum in the system. See the grounding section on Page 8. The PPA-2 itself is very, very quiet, so if you

are hearing hum it is caused by something else in your system. There is most likely something in your system

causing it and you need to look at your grounding, wire position or for some other problem. It should, and will

be, quiet and hum-free.

Branchement des entrées

Connexion d’un tourne-disque au préampli Phono PPA-2

Le Phono 1 est uniquement asymétrique (prises RCA), le Phono 2 peut être symétrique (XLR) ou asymétrique.

Les câbles du tourne-disque au PPA-2 doivent être aussi éloignés que possible des câbles d’alimentation, dans

la mesure du possible. S’ils doivent se croiser, faites-le à angle droit si vous le pouvez.

En règle générale, une connexion (XLR) sera plus immunisée au ohm ce qui en fait un type de branchement à

privilégier. Cependant, vous devez faire attention à ce que la coque du XLR ne soit pas connectée directement

à la ligne de terre dans le connecteur XLR. Ils DOIVENT être indépendants. La coque est le blindage externe du

câble et du connecteur et doit être la connexion au CHASSIS. Le ﬁl de mise à la terre dans le XLR est torsadé

avec un (+) et un (-) équilibrés et doit être la masse du signal ou du bras de lecture. Tout ceci peut être conﬁrmé

avec un ohmmètre.

En raison du niveau de signal très faible provenant de votre cartouche phono et quel que soit le style que vous

choisissez, veuillez utiliser le meilleur câble possible à cet emplacement.

Après avoir eectué vos connexions audio, reportez-vous à la page 8 pour régler adéquatement les

commutateurs DIP.
