Initial Setup
•
•
•
•
•
•
•
•
•
Carefully remove the ProLogue Eight from its packaging.
Use the white gloves to prevent fingerprint smudges.
Remove the tube cage by carefully pulling it up and away from the CD player.
Check that each tube is firmly seated in its socket. Use gloves.
Replace cage back in its place if desired.
Ensure that the power switch is off (down).
Connect output of CD player with input of pre amplifier or integrated amplifier.
Plug the power cord into the CD player, then into the wall socket.
Switch the CD player on; the output will be muted for 30 seconds while the tubes
warm up.
•
Switch the amplification on after the mute of the CD player is released.
The tubes will be warmed up and ready to use in two to three minutes. And like all com-
ponents, the ProLogue Eight CD Player takes approximately 100 hours to fully break-in.
However, it is not necessary to have a CD playing to break in the player—simply leave the
unit powered up.

General Operation
Turning the unit on/off
Turn on the Power Switch (POWER) on the left side, the unit will first close the disc tray,
the display will show PRIMALUNA PL8 CDP, and the unit will perform a self-check. When the
display shows READING, the self-check has been completed and the unit is ready to read
the disc.
Playback
•
Press the Stop/Open Button on the front panel or the remote control to open the disc
tray. Place the compact disc in the disc tray label-side up.
•
•
•
Press the Stop/Open Button on the front panel or the remote control to close the tray.
Once the display indicates the number of tracks on the disc and the total time of the
disc, press the Play/Pause Button on the front panel or the remote control to start
playback. If the disc tray is open when you press the Play/Pause Button, it will close
automatically and start playing.
Normally, the disc will start playing with track 1. However, you can select a different track
by pressing the Skip Buttons.
Track Search
•
•
•
During playback or in STOP mode, you can select a track to play by pressing the
Skip Buttons.
Press the Forward Skip Button to advance to the beginning of the next track. If the
current track is the last one, pressing this button will return the player to track 1.
Press the Backward Skip Button to reverse to the beginning of the previous track. If
the current track is the first one, press this button to reverse to the beginning of the
last track.
Pause
During playback, press the Play/Pause Button on the front panel or the remote control to
temporarily pause playback.
Press the Play/Pause Button again to resume playback
When the player is in PAUSE mode, the disc motor is still spinning. Since leaving the player
in this condition can shorten the lifetime of the motor, do not leave the player in PAUSE
mode for a long period of time.
In PAUSE mode, after advancing or reversing to the next track, the unit will still be paused.

The Remote
The functions of the PrimaLuna Remote Control are self-explanatory. The remote controls
all the basic CD player functions outlined above and on the next page. It will also control
source selection, volume, and triode/ultralinear switching on the DiaLogue Series integrated
amplifiers.
The PrimaLuna Remote Control has two high quality silicon rings on each end to protect
against damage of the remote control itself as well as your furniture. These rings can be
easily removed in case batteries have to be replaced or if you plain just don’t like them.
In the event your remote control does not function, please check batteries and if necessary,
replace with new (1.5V AAA-size). To access the battery-compartment, remove the rubber
rings and unscrew the back plate. If the remote still does not function, contact your dealer
for further assistance.

The SuperTubeClock
This is where the magic happens... the SuperTjoebClock replaces the solid state oscillator
normally found in a CD player’s digital clocking device with a mini triode vacuum tube.
When you reclock a cd-drive, any noise that is generated here appears unfiltered and
unattenuated at the input of the decoder chip in the cd-player and injects jitter, which
from then on is an undistinguishable part of the digital audio stream. No amount of cleaning
will ever be able to remove this noise once it reaches this point; it has become part of the
audio signal. There is a distinctive loss of dynamics, tonal purity, intertransient silence, and
sense of timing. We call this “noise modulation.”
When the clock is used to clock the DAC chip, a similar situation occurs as described above:
the noise appears at the location where the digital audio stream is converted to successive
steps in a staircase wave, which represents the analog audio signal. Each step has to be
EXACTLY 1/441000th, 1/96000th, 1/176400th, or 1/192000th (depending on whether there’s
oversampling or upsampling, CD or DVD). The injected noise introduces a deviation in time
which is the exact replica of that noise. This means that the audio signal at the outputs of
the DAC chip has the noise riding on it, again as an inherent part of the signal. No amount
of filtering will remove the noise once it reaches this step. Again we experience that smear
and detail masking, with that distinctive loss of dynamics, tonal purity, intertransient
silence, and sense of timing.
By replacing the standard solid state oscillator with a tube, we have significantly lowered
the amount of jitter and noise, resulting in superior detail retreival. This in turn yields
superior detail and dynamics from top to bottom, and improved overrall musicality.

Tube Information
The 12AX7, 12AU7 and 5AR4 tubes will have a life of about 10,000 hours.
Here are some tips on using tubes:
Do not use treatments on tube pins or in sockets.
If you decide to experiment with other types of tubes, it is critical that you first turn the
power off to the CD player, then turn the volume down completely on your pre-amp AND
also switch your pre-amp to a different source. We recommend you not swap tubes in and
out repeatedly because every time you insert a tube, you increase the chance of loosening
the tube sockets. It’s okay to have fun, and we support that, but don’t go crazy and swap
tubes in and out twenty times a day.
The ProLogue Eight has a warm-up time of just a few minutes. Although it is not wise to
leave tube components on 24 hours a day, you may leave this player on if you choose, but it
will result in more frequent tube replacement. Through experimentation, come to a conclu-
sion that fits comfortably with your lifestyle.
Break-in yields improvements. So, when your CD player is new, or when you re-tube it, it
may take a little time to settle in. There is however no fixed “time rule” for break-in.
*IMPORTANT! Please note that tubes can vary electrically, and by plugging in the wrong
type of tube (i.e. 6922 for a 12AX7) you can damage the unit and void your warranty.
Common replacements:
12AX7: ECC83, ECC803S, E83CC, 7025, CV4004. You can also use a 5751, but please note
that the 5751 is a lower gain tube than a 12AX7 and the sound will be altered.
12AU7: ECC82, ECC802S, E82CC, 5814, 6189, CV4003
5AR4: GZ34, CV1377 are equivalent. 5V4G, 5T4, and 5Y3 will also function fine with
small sonic changes that you may want to experiment with. Do not use other types as
damage may occur.
Some tubes and tube sockets
(in this case, the 5AR4/rectifier)
have a center “key” which must align.
If you force it when misaligned,
you will damage important and
expensive parts of your CD player.

Fuse Protection
A note on fuses: NEVER wrap fuses in aluminium foil as a stop-gap to buying new ones. Fus-
es are safety valves. They should always be replaced with the exact same value and type.
NEVER attempt to check or replace a fuse while the CD player is plugged in. Turn off the
power amp first and after that the preamplifier and then the CD player. Unplug all speakers,
components and AC cords before continuing. Wait 10 minutes to let tubes cool down and the
circuit to fully discharge.
Mains Fuse:
The mains fuse is located on the rear of the CD player,
just below the power cord socket (see picture on right).
The fuse rating is 2 Amp slow blow 5 x 20mm for 100-120VAC
and 1 Amp slow blow 5 x 20mm for 200-240VAC.
Replace with the same type and value fuse only!
The fuse holder can be snapped out using a small slotted
flat-head screwdriver.

PrimaLuna© ProLogue Eight
Troubleshooting
No output. Power is on, but power LED is off and tubes do not light up.
Mains fuse is out. Replace fuse per instructions on page 9.
No output. Power LED is on and tubes do light up normally.
The CD player stays muted for 30 seconds when powered on. Check to make sure
all interconnects are securely connected. If all seems to be OK check other
equipment in use.
Remote control does not respond.
Batteries are low and have to be replaced. Strong (sun)light may also disturb
the remote control signal. Make sure there are obstacles between remote control
and CD player.
Noise coming from one channel.
Noisy tube. First swap the 12AX7 tubes left to right. If noise follows tube swap,
than you have found the problem tube. If noise does not follow, swap the 12AU7
tubes left to right. If noise still persists, contact your dealer.
Hum coming from one channel.
Check 5AR4 tubes to make sure they are seated properly. Swap L to R , If hum
follows tube then replace faulty tube.
Noise/distortion coming from both channels.
Tubes may be in need of replacement. Read page 9 for tube basics and
replacement options.
Please also check the other equipment in use for failure or improper connections.
If you try these possible solutions and problems persist, contact your local distributor for
further investigation.
Tube Selection
While matched tubes are not a requirement, they’re still recommended if you want to get
superior results. You can get the very best in replacement tubes as well as rare vintage NOS
(New Old Stock) from us and other parties if you wish to upgrade. In the USA, Upscale
Audio’s inventory of New Old Stock tubes is the largest you can find. Elsewhere, indepen-
dent suppliers can assist you in making the best choice

Herman van den Dungen: PrimaLuna in Italian language is “First Moon”. My
grandfather was the first “Herman”. My grandmother, an aristocratic lady in a
small Dutch village, had a special name for her husband: “Maantje”, which means
Little Moon (which is now also the name of our small dog), van den Dungen. The
people in the village adopted that name, and having a strong accent, they soon
called him “Maontje” van den Dungen. My father’s first name was Cor, but in
the village it was of course “Cor from Maontje van den Dungen”. I was of course
“Herman from Cor from Maontje van den Dungen” …… etc. That’s why I thought
of First Moon as a brandname and that’s why the logo is how it is ……
Loris Arrigucci: PrimaLuna believe it or not ... I discovered a small town located
50Km north of Milano called Primaluna!!! Please get yourself a map from Italy.
You’ll find Primaluna town near the upper-right corner. It is located 50Km north of
Milano near the Lake of Como. This should eliminate every doubt regarding “ital-
ian” origin of Primaluna name. I’ve read the “history” section of the Primaluna
village web site and found the following (literally translated):
One probable interpretation of the name of the village comes from latin “Primum
Lumen”, which means “First Light” of Christianism, since the very first evidence
of Christianism in this region dates 495 Annus Domini. “First Light” translates into
“Prima Luce” in Italian and this seems very interesting to me: PrimaLuce (First-
Light) is the first light that we, hi-fi lovers with small budgets, can see in this
world of darkness populated by way too expensive esoteric gears
