PrimaLuna ® DiaLogue One

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 "italian" 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 (FirstLight) 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 ……

PrimaLuna ® DiaLogue One

THANK YOU!

We would like to thank you for choosing our PrimaLuna DiaLogue One vacuum tube integrated amplifier as the heart of your music system. The DiaLogue One is the first member of the next level up of our family of affordable, high-quality tube products. The designers and builders of the PrimaLuna equipment all have a long history in high-end audio. We feel that it's time to offer a range of affordable audio instruments that can easily compete with today's most expensive brands.

We firmly believe that our quality level will be a difficult standard for other products in the market to match.

This PrimaLuna DiaLogue amp features:

• Hand-made construction with the finest point-to-point wiring, using workmanship that is equal to or better than any product you can buy at any price.

• A heavy gauge steel, fully vented chassis with a five coat finish. Each coat is hand-rubbed and polished.

• Premium parts: toroidal transformer for power supply; custom designed -in conjunction with one of the most prestigious transformer designers in the USA- encapsulated output transformers for lowest hum; wide bandwidth for great bass and extended highs; ceramic tube sockets; ALPS volume control; Nichicon and Realcap capacitors; gold-plated heavy duty WBT style speaker terminals; gold-plated panel mounted input jacks.

• SoftStart™ circuit for extended life of sensitive components, plus a reduced chance of tube failure from thermal shock.

• Adaptive AutoBias™ exclusive to PrimaLuna. This circuit monitors and smoothly adjusts bias constantly and instantly, reducing maintenance and increasing performance due to the dramatic reduction in distortion.

• Tube plate fuse to protect the amp output stage. Other amplifiers might need a trip to the shop if a tube fails; not this one- just plug in a new tube, fuse, and go.

• Ultralinear or Triode mode switchable by remote control

• 5 line level inputs, 1 Stereo Home Theater Pass Thru

• 1 tape out

• Heavy metal system remote control included

Premium tubes are available from us and other parties if you wish to upgrade. In USA, Upscale Audio's inventory of New Old Stock tubes is the largest you can find. Elsewhere, independent suppliers can assist you to make your best choice.

We hope that the PrimaLuna DiaLogue One amplifier will make you want to follow our next steps in expanding this new range of products. If you have any questions or comments, don't hesitate to contact us. You can also share your thoughts with others at www.audioreview.com or other review sites. On the www.primaluna.nl website you will find links to these and other websites. Our prices are kept low by using word-of-mouth and customer feedback, and we would appreciate hearing what you have to say about our product. If you need service during or after the warranty period, contact us.

Thanks again for your support!

Fuse Protection

A note on fuses: If "someone who knows" tells you to wrap fuses with aluminium foil to avoid wasting money on new ones, it's best not to take his advice. Fuses are safety valves. They should always be replaced with the exact same value and type.

Warning: Never attempt to check or replace a fuse while the amp is plugged in. Turn it off and unplug all speakers, components and AC cords before continuing. Wait 10 minutes to let tubes cool down and the circuit to fully discharge.

Plate Fuse:

The plate fuse is located inside the amp, on top of the Adaptive AutoBias™ board. To replace it, remove the bottom plate using a Phillips #2-type of screwdriver. The fuse is located in a small plastic case on the end of the Adaptive AutoBias™ board. Refer to the pictures on this page. Remove the top cover. The fuse will be held on by the cover. Remove it by twisting the fuse out of the holder.

Replace with a Littelfuse® 218 Series 250mA Slo-Blo® 5 x 20 mm fuse. The cover will snap back into place. Re-install bottom plate of the amp.

Mains Fuse:

The mains fuse is located on the rear of the amplifier, just below the power cord socket (see picture on this page). The fuse rating is 1 x Littelfuse® 213

Series 1A Slo-Blo® 5 x 20 mm fuse for 100-120VAC and Littelfuse® 213

Series 0.5A Slo-Blo® 5 x 20 mm fuse for 200-240VAC. Replace with the same type and value fuse! The fuse holder can be snapped out using a small slotted flat blade screwdriver.

PrimaLuna ® DiaLogue One

Warning

To prevent serious injury, electrical shock or fire:

• Do not operate with bottom plate removed.

• Keep away from rain and moisture.

• Always disconnect all cable connections to and from amplifier before changing fuses and/or tubes.

• Do not replace fuses with any fuse other than the same type and rating as used by the factory.

• Do not replace tubes without reading instructions.

• Do not replace fuses or tubes if you have any doubt about your ability to do so. We accept no responsibility for any personal or material damage due to incompetent use or users.

Adaptive AutoBias™

Exclusive to PrimaLuna, this circuit monitors and smoothly adjusts bias constantly and instantly. The genius of this design is that the Adaptive AutoBias™ actually improves the overall sound quality and performance of the amp. Between 12 and 30 Watts, measured distortion levels drop by over 40%. In addition, tubes do not have to be matched, and there is no bias (re-)adjustments needed, ever.

Furthermore, the PrimaLuna is equipped with Soft-start™, which brings the amplifier on line slowly to prolong the life of internal components, including the tubes. This makes the PrimaLuna a joy to own and operate.

While matched tubes are not a requirement, it is still recommended if you want to get the very best results. You can get the very best in replacement tubes as well as rare vintage NOS (New Old Stock) tubes 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, independent suppliers can assist you to make your best choice.

PhonoLogue Phono Stage (Optional)

Your DiaLogue One integrated amplifier comes without a phonostage, but we have a high quality optional internal phono stage available. The PhonoLogue phono stage can be installed at any time by your dealer or any qualified person.

The PhonoLogue MM phono stage with RIAA equalization, requires no extra plugs or connectors. It fits

(by soldering) on the existing RCA's of one of the inputs. It provides superior sound quality on a tiny footprint. We use Surface Mount Technology implementation for shortest signal paths as well as minimum parasitic capacitances and inductances. Excellent parts throughout, selected on sound quality as first priority: miniature film capacitors, minimelf resistors, superior opamp for highest accuracy, lowest noise, highest speed and most robust drive capabilities into the RIAA correction stage, resulting in a very detailed, open and lifelike sound from any LP record. Low impedance electrolytics, super low-noise powersupply. Dimensions: small as a big stamp!

The functions of the PrimaLuna DiaLogue Remote Control are self-explanitory. The remote controls source selection, Triode/Ultralinear switching, volume & mute functions. The DiaLogue remote will also control the basic functions of the PrimaLuna ProLogue 8 CD Player.

The PrimaLuna DiaLogue Remote Control has two high quality silicon rubber 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.
