- Page 2 LampizatOr- The Horizon DAC Manual WARNING: as every DAC comes with a 7 days testing period (please to confirm it - ask your dealer first), during this time it is not allowed to open the DAC. The screws are protected with a seal. You have to decide, if you like the sound and you want to keep it.
- Page 3 Thanks to a revolutionary chip technology, like nothing we ever saw before - it was possible to design a DAC that creates a class of it’s own. Never in the twelve years since LampizatOr's founding have we taken on such an ambitious, expensive and labor intensive project.

LampizatOr- The Horizon DAC Manual L-POS L-NEG L Neg And R-POS R-NEG R Neg And RECTIFIER FRONT Tube positioning Left channel - positive phase, Right channel positive phase, Left channel - negative phase, Right channel negative phase, are the power pentode tubes (must all four be equal and the same). -
Page 7: A Quick Guide To A Smooth Start
LampizatOr- The Horizon DAC Manual A quick guide to a smooth start THE BUTTONS The whole DAC can be operated simply by the three buttons on the front. Left and right button are simply VOLUME UP and DOWN. When you hopld the button the volume change will accelerate to the end of the scale. -
Page 8: Introduction
LampizatOr- The Horizon DAC Manual Introduction Thank you for choosing Lampizator HORIZON DAC. We created it with huge research effort to deliver not only world class musical performance, rivalling the most expensive DACS money can buy, but also to offer very long life of the product. Simply speaking –... -
Page 9: Horizon Design
LampizatOr- The Horizon DAC Manual Horizon design This DAC is like no other, mainly due to the fact it is using dual triodes as DAC output converters to voltage and power pentodes as triode loads, triode buffers and voltage stabilisers at the same time. The power pentodes seem to be much too large and much to expenceive to be used as “small signal”... -
Page 10: Data Formats
LampizatOr- The Horizon DAC Manual Data formats The DAC is capable of automatic recognition of all sampling rates from32 to 768 kHz and bit rates from 14 to 32. Since few if any transports offering S/PDIF format of the 192 kHz exist in the consumer market, it is hard to guarantee the operation but on the professional ones which we tried –... -
Page 11: The Heat Issue
DAC always on, than to switch it on and off more than necessary. The lampizator DAC with tube rectifier has a slow start feature which brings the high voltage supply gradually up, at the rate of two- to five volts per second. The PSU reaches 275 V DC after 60 seconds. -
Page 12: Cabling And Cable Handling
LampizatOr- The Horizon DAC Manual equipped with voltage down feature (bleeders) which reduce the power voltage upon switch-off at roughly the same rate. On top of that – the tubes are operated around 25% of full nominal power, which greatly increases their life expectancy. Combining all the factors together, the tube lifetime should be anywhere between 10 and 20 years, assuming the player is switched off only once per day, for the night. -
Page 13: Tube Rolling And Replacement
LampizatOr- The Horizon DAC Manual Tube rolling and replacement W took an expensive and painful decision to sell the DAC with the best tubes we can find in consistent sustainable supply. Therefore we feel you should not be tempted to change them for any reason. - Page 14 LampizatOr- The Horizon DAC Manual Here are some GENERAL practical tips for tube rolling: 1. Tube compatibility- many people ask “is the tube X compatible with Y?” and the answer is of course - it depends. Tubes can have completely different bases but be compatible by parameters and can be swapped by means of an adaptor.

It al depends on the DEMAND of our circuit. Some Lampizator tube stages demand only 2 mA in total, some can demand 40mA and more. Horizon DAC demand in total for 2 channels is 80 mA.

Page 17: Aging Problems
LampizatOr- The Horizon DAC Manual Aging problems As already explained above, the DAC should age very very slowly. The digital PCB should last a lifetime. The transformer, the paper in oil caps, the cables, plugs, sockets – should last a lifetime. There are electrolyte caps which we selected from premium brands and they should last circa 25-30 years. - Page 18 LampizatOr- The Horizon DAC Manual 1. Power supply with the DAC power management relay, allowing to switchON/OFF the whole DAC via the remote while keeping the volume module powered. 2. The display - nixie pair which is our GUI. 3. The microprocessor board with memory, firmware and the chip that controls the relays 4.

Page 19: Cooperation With The Preamp
LampizatOr- The Horizon DAC Manual COOPERATION WITH THE PREAMP The DAC with volume control should sound audibly cleaner and more direct without any preamp between the DAC and the amp. The preamp, however good, will veil a lot of the DAC’s natural clarity, speed and directness. If you feel you need the preamp nevertheless, use DAC at the full volume with bypass (63 on the display). -
Page 20: The Toslink Connection
Usually Toslink ports are installed in cheap low end gear and the power supply to Toslink is completely neglected. Not in LampizatOr DAC. If you have Toslink in your DAC you can be sure it will sound good and not degrade the sound. Of course providing that the transmitter part of the link is at least semi decent. -

Page 23: Mac Os Operation Of Usb Output
After plugging the DAC by the USB cable and turning it on, within 3 seconds the device should show up on the MAC. Note: the device will NOT be described as Lampizator DAC but as Amanero Combo module. To verify what is going on, please go to the “apple sign” in top left corner of the screen and choose PREFERENCES and then the loudspeaker icon - SOUND. - Page 24 LampizatOr- The Horizon DAC Manual Above: on that list the USB LAmpizator should appear under INTERNAL SPEAKERS. Next thing to check is MIDI SETTINGS of the MAC computer. We go to the top right corner of the screen and press SPOTLIGHT (Loupe): We type in the search line MIDI SETUP and ->...

Page 25: Listening To The Music
LampizatOr- The Horizon DAC Manual LISTENING TO THE MUSIC some practical tips Please use good shelf for the DAC. Do not place it on speakers, subs, or even on transports or amps. Again - tubes hate vibrations. If you try the special devices for placement, we feel that: granite or marble is bad (ringing). - Page 26 LampizatOr- The Horizon DAC Manual on the hard floor greatly enhances our perception of music. It is advisable to have rug or carper between listener and speakers but not under the feet. 8. It is advisable to put something soft directly on the wall behind the speakers 9.

Page 29: I Plugged Everything But I Get No Sound
If you use a computer with USB connection - is the driver recognized ? Is Windows driver installed (JL Lampizator USB) Is the computer’s output device properly defined to be Lampizator USB and not speakers, SPDIF, Toslink or Intel? Is the computer’s digital volume control set to maximum ? Is the USB cable not of USB1.0 type, not longer than 2 m and not with ferrite rings on it? -
