FAQ (Frequently Asked Questions)

No. An adult who has completed training as a Laser Display Operator for Class 4 laser devices must operate the laser projector.
The operator should be aware of and follow all regulations, requirements, and laws in the country where they operate the Class 4 laser system.
The manufacturer holds no responsibility for injuries or damages caused by the use of this laser display equipment.

That mostly depends on venue size, the projection distance you need to cover, and any ambient lighting that may interfere with the laser projection (e.g., an LED screen).

• Small to Medium Indoor Venues and Events (Clubs, Theatres, Weddings)

3 to 10-watt Clubmax FB4 projectors provide top-quality performance and enough output for most indoor venues with capacities up to 3,000 people. These are also great systems for laser graphics and laser mapping applications.

• Large Clubs, Arenas and Amphitheatres

The Atom XR 2.0 series laser projectors (18 and 30 watts) are a perfect choice for larger indoor and smaller outdoor spaces for up to 6,000 people. Their high-quality output and low beam divergence ensure bright and colourful laser effects under any circumstances.

• Outdoor Stadiums and Festivals

The high-power output (60+ watts) Atom XR 2.0 and AtomXM projectors are touring-grade machines, designed for maximum visibility over hundreds of meters in large-scale outdoor environments. They are compact, light, built and tested to IP65 standard, extremely reliable and packed with professional features.Alternatively, the Spectrum series OPSL-based lasers offer an unbeatable range of colours and beam quality second to none. These units come with super-fast scanning and are often used for long-distance laser graphics and mapping projections.

All three integrate Pangolin FB4 control hardware, and all are top-notch in build quality, but they differ in certain aspects:

• Clubmax Series

In today's terms, they are low-power RGB lasers, great for nightclubs, indoor events of any kind and hire. They are compact, robust and tuned to perfection. They handle demanding, heavy party environments really well.

• Atom XR 2.0 Series

Medium- to High-power RGB laser systems with power outputs of 18, 30, and 60 watts are housed in a robust but small, very light IP65 housing, offering professional performance in every aspect and touring-grade features.

• Spectrum Series

Heavy-duty lasers with superior beam quality, an extended range of colours, and fast scanners. The Spectrums are often utilised when pristine beam quality or a graphically strong system is required.

Yes! KVANT manufactures unusually powerful outdoor lasers like the Architect W500B and W1500B and also laser-based moving heads called KVANT 600Prestige Beam. These fixtures utilise high-density optical engines designed to project highly concentrated laser beams across city skylines, mountains, and architectural structures with visible projection distances of up to many kilometres.​

Yes, of course. All KVANT laser display systems imported and sold in the United States fully comply with FDA/CDRH (Centre for Devices and Radiological Health) standards. Every US-bound unit includes required safety hardware, including a physical key switch, emission delay, interlock system, mechanical shutter, and scan-fail safety circuit.
Operating high-power Class 3B or Class 4 lasers commercially in the US also requires a valid FDA Laser Light Show Variance, which KVANT and authorised distributors such as Pangolin can assist clients in obtaining.

All KVANT laser projectors incorporate a comprehensive, multi-layer safety package:

• Scan-Fail Safety: Hardware monitoring that instantly shuts down or masks the laser output (< 20 ms) if scanner motion stops, preventing hazardous static beams.
• Electromechanical Shutter: Physical beam stop triggered by interlock interruption or emergency stops.
• E-Stop & Remote Interlock: Daisy-chainable emergency stop connections allowing instant shutdown via hardware control buttons.
• Integrated Aperture Masking: Mechanical masking plates and digital software zones to physically or digitally block laser beams from striking audience areas.

KVANT systems feature industry-leading optical performance:

• Scanner Speeds

Standard models offer 40 kpps @ 8° ILDA (using Pangolin ScannerMAX or KVANT optical scanners), with optional upgrades to 60 kpps or Saturn 1 scanners for high-speed graphics, text, and 3D vector projections.

• Beam Divergence

Kvant’s semiconductor FAC diode modules deliver low beam divergence—typically less than 1.0 - 0.6 mrad (full angle)—ensuring beams remain sharp, tight, and bright even over great projection distances.

All recent KVANT laser projectors come with integrated Pangolin FB4 MAX hardware as standard. This allows flexible control options without any other external laser interfaces:

• Network / Ethernet

Direct control via streaming PC running Pangolin QuickShow or BEYOND software.

• Lighting Consoles (ArtNet / DMX)

Trigger pre-programmed laser shows, queues, and parameters directly from lighting desks over DMX512 or Art-Net network lines.

• Stand-Alone

Auto-play pre-programmed geometric shows and cues stored directly on the FB4’s internal SD card.

• ILDA Pass-Through

Traditional, but outdated analogue 25-pin ILDA connection for legacy control hardware.

Yes. Because KVANT integrates Pangolin FB4 hardware natively, lighting designers can patch KVANT projectors directly into lighting consoles (such as grandMA2/3, ChamSys MagicQ, or Avolites) via DMX or Art-Net. Operators can then control laser positions, colour mixing, geometric cues, speed, and safety zones using standard console fixture profiles.

Yes. In addition to entertainment lasers, KVANT manufactures custom OEM diode laser modules for laboratory, research, medical, and specialised industrial automation applications. Kvant designs custom multi-wavelength RGB and monochromatic optical modules with custom power outputs, precise beam-shaping optics, high-frequency analogue modulation (>100 kHz), and thermal management systems tailored to client specifications.

Yes. KVANT provides bespoke OEM/ODM manufacturing services. This includes custom CNC-machined or foamed aluminium optical housings, custom paint finishes/branding, custom beam divergence parameters, and non-standard wavelength combinations (such as yellow 577nm, deep blue 445nm/462nm, or infrared range) for specialised visual or scientific applications.

KVANT laser projectors range from low-power Clubmax systems starting at approximately $1,500–$3,000 up to high-power festival projectors and sky lasers exceeding $20,000–$50,000+.
Pricing varies based on total output power (wattage), model series, scanner speed and custom upgrades.
You can purchase KVANT lasers globally through authorised sales networks, regional distributors, and strategic partners such as Pangolin Laser Systems in the US.

Yes. KVANT maintains dedicated rental stock and offers turnkey production services for major international festivals, broadcast television, concerts, and architectural displays. Services include high-power equipment rentals, certified laser safety officers (LSO), custom laser show design, and on-site technical installation support.

All new KVANT laser display systems come standard with a factory manufacturer warranty (typically 24 months, expandable depending on product tier).
Support includes hardware repairs, maintenance services and firmware updates via service centres across Europe, North America, Asia, and Australia.

The Conformity Declaration is part of the user manual. Because the corresponding standards are updated periodically, please contact a distributor or one of our sales representatives to obtain the latest Conformity Declaration for your laser projector.

A laser projector contains no poisonous materials or dangerous components. So you can dispose of it the same way you would any other electronic equipment. For more details, please get in touch with your local waste authority.

The Prestige Beam is certified as a Class 1 laser device under the IEC 60825-1 standard and simultaneously classified as Risk Group 3 under the IEC 62471-5 and IEC 62471-7 standards, with a hazard distance of 226 meters. These standards apply to all high-output light sources, including discharge lamps, LEDs, and phosphor-based beamers.
Looking directly into the beam from a distance shorter than specified may result in eye damage due to thermal effects and the eye's sensitivity to light.
Obey the minimum safety scanning distance of 226 metres when using the product!

There is a danger of fatal electric shock! Turn off the projector immediately. Disconnect the projector from the AC mains power supply.
A qualified electrician must check the mains power cable and the socket.

Turn off the projector immediately. Disconnect the projector from the AC mains power supply.

A qualified electrician must check the mains power cable and the socket.

The two common reasons are:

1. A mains power cable that is too long, with the N (blue) and PE (yellow-green) cables joined. The 3-wire connection is essential.
2. Disconnected, not connected, or interrupted PE wire in the AC mains power cable or AC wall plug.

You may not modify the electronic circuitry of laser projectors without prior authorisation and approval from Kvant's technical support representative. Any unauthorised modifications will result in immediate warranty termination.
There is a risk of electric shock and the risk of injury or property damage from laser radiation. Unauthorised modifications to the circuitry may change the projector's functionality and specifications, making it noncompliant with regulations and standards for Class IV laser devices.

The operating temperature range for Kvant laser projectors is +10°C (50°F) to +35°C (95°F). Using projectors in environments with air temperatures between 35°C (95°F) and 45°C (113°F) is not harmful to the projector, but it limits its ability to dissipate heat efficiently, resulting in reduced nominal power output or complete cutoff.
There is a risk of permanent damage to the laser projector if used in temperatures exceeding 45°C (113°F), in which case the warranty is voided.
Never place and use projectors near objects that generate excessive heat, such as radiators, powerful discharge lighting, or warm air outlets.
For use in temperatures exceeding 35°C (95°F), we highly recommend installing the projector in the Monsoon box with a built-in AC unit.
As a temporary solution, you can use a small AC unit and direct its output towards the projector's intake fans.

The operating temperature range for Kvant laser projectors is +10°C (50°F) to +35°C (95°F).
If you use it outside this range, we recommend the Kvant Monsoon. This robust, durable enclosure protects your delicate equipment, such as laser projectors, from harsh weather conditions, extreme temperatures, and high humidity.
As a temporary solution, you can use an electric heater to pre-heat the air entering the laser projector. Place the heater at the correct distance from the projector so the air entering the laser projector is between +10°C (50°F) and +25°C (77°F). The projector may get damaged if the heater is placed too close to the projector's airflow inlets or rear control panel.

It is necessary to reset the output directions (alignment) of individual colours (laser beams) inside the projector. There are several ways to join them together, but only one is correct. The correct one ensures perfectly joined beams at both short- and long-distance projections. Please check the projector's User Manual (chapter Beam alignment) for beam alignment instructions.

Try replacing the ILDA cable between the projectors with a new one, and check the ILDA input connector on projector #2 for any damage. If that doesn't solve the issue, swap the projectors and see if it works.
If both work fine, then projector #1 has a faulty ILDA output.
If neither works, projector #2 has a faulty ILDA input. Please contact your distributor or the technical assistance team at Kvant Lasers, s.r.o. for further help.

This is usually an optical issue, such as scratches, dust, or dirt on components along the beam's path from the source to the output aperture, or on the aperture glass itself.
Use a clean, fine-cotton cloth soaked in isopropyl alcohol to clean the output window. Clean carefully so you don't scratch the surface with dirt particles already stuck to the cloth.
Remember that the output window's anti-reflection surface can be easily scratched and permanently damaged by improper cleaning.

This is usually an optical problem such as scratches, dust and dirt on the components on the beam's path from its source to the output aperture (scanner mirror, dichroic filter, bounce mirror).
To inspect and clean the optical components, turn off the projector and disconnect it from the mains power supply.
Use a clean cotton bud (swab) soaked with isopropyl alcohol to clean the optical component's surface. The bud must be “rotated” against the direction of movement during cleaning to avoid the surface getting scratched by dust and dirt already taken from the surface.
After one full spin (360 degrees), dispose of the cotton bud and use a new one to continue cleaning.
Remember that the optical parts' surface can be easily scratched and permanently damaged by improper cleaning.

The laser projector has automatic over-temperature protection that reduces each laser module's power output to 50% if its temperature exceeds the preset level. After the temperature stabilises, the output power returns to 100%. If the temperature at 50% power output still rises, the power output is cut to zero until the temperature returns to safe values.
If the projector reduces the power output of one or more colours, it could be due to insufficient cooling from poor airflow, overly warm cooling air, or faulty fans on the main heatsink.

The most likely reason is the activated Colour Balance function, which balances all the primary colours in the correct ratio so mixed colours are precise. For example, projected white is nice and crisp, without a blue cast.
To turn this function on or off, press the little button next to the FB4 display on the rear panel. This feature is switched ON when the yellow LED indicator next to this button is on.
When the Colour Balance function is disabled, all colours return to 100% power output.

The number of projectors running on a single E-STOP Remote is unlimited. Each projector amplifies the E-STOP signal for the next projector in line.

The maximum length between two projectors is defined by the internal resistance of the cable connection wires used. The total resistance of one wire within the connection must be below 400 Ohm. Standard microphone XLR cables have resistance typically below 0,1 Ohm/meter. So the maximum distance between two projectors with such cable is approximately 4km.

We recommend daisy-chaining a maximum of 6 units on a single Ethernet line. If you connect more than six projectors, you will likely notice data packet loss, resulting in disruptive movement of projected graphics and animations.
For the best possible multi-laser data connection quality, we recommend using a high-speed 1Gbit data connection between the PC and the data switch. Also, we recommend separating 100Mbit data connections between the data switch and each projector.

Yes. Laser projectors supplied to the US market come with an E-STOP Remote with Auxiliary Input for a Normally Closed (NC) door switch.
The client can connect an interlock jumper, a door switch, or any additional safety item to this input, such as the output of a PIR sensor to monitor the area around the laser projector.

All Kvant projectors manufactured from 06/2014 onward are fully compatible with each other. To check compatibility with older Kvant projectors made before 05/2014, please contact the technical support representative at Kvant Lasers, s.r.o.
Suppose a Spectrum LD projector with a Saturn9 scanning set is used with non-LD projectors. In that case, it is recommended to decrease the maximum size and scan rate of the non-LD system(s) to meet the LD system limits and ensure full compatibility.
If more systems from various manufacturers are used together, it is recommended to use a separate ILDA signal source for each manufacturer’s group.

It is necessary to remove the laser projector from its flight case as soon as possible - within 24 hours at the latest after the show- and let both the projector and flight case fully dry out.
NEVER turn ON the projector before it is 100% dry inside out.
When ready, please check the status of the anti-humidity cassette containing silica gel. For more information about this topic, go to the User Manual (chapter Maintenance).
Insufficient drying of the projector and its flight case can cause permanent damage to the projector (mould, corrosion) and void the warranty. Powering up a wet or damp projector can cause electrical shock, injury, or fire risk. It can also permanently damage the projector, which voids the warranty.

No. The Rain cover was designed as emergency protection against rain or snow for short-term outdoor use. During heavy rain and wind, it can get soaked. Therefore, remove the rain cover from the projector after every use and let it dry with the projector.
Insufficient drying of the projector and its flight case can cause permanent damage to the projector (mould, corrosion) and void the warranty. Powering up a wet or damp projector can cause electrical shock, injury, or fire risk. It can also cause permanent damage to the projector, which voids the warranty.

No. Our Rain cover works efficiently ONLY for projectors set in a horizontal position- that is, with rubber feet facing the ground.
If you use the rain cover any other way, it won't protect your equipment.

Laser beams hitting cracked or broken glass will be scattered uncontrollably into unwanted directions, creating a risk of damage to eyesight, health or property.
Broken or missing aperture glass lets humidity, water, and dust into the laser projector's optical compartment, which can permanently damage the system.
It is essential to replace the damaged or missing aperture glass before using the laser projector.

The projector must not be operated if the housing is damaged to the level that it causes visible gaps between the projector's adjacent faces. These gaps allow humidity, water, and dust into the laser projector's optical compartment, which can permanently damage the system.
There is also a risk of laser emission leaks from other parts of the system, which contradicts the IEC 60825-1 safety standard.
Repair or replace damaged housing parts before operating the projector again.

No! The projector must not be used, lifted or hung. Never attempt to repair a bent or fractured eyebolt. Replace it with a new one with the same or higher load capacity.

Yes, it's OK. Kvant projectors have built-in automatic regulation of the fan speed. After powering up the projector, all cooling fans will run at 100% speed for about 2 seconds. Then their speed is adjusted according to the heatsink’s temperature.

Clubmax (without FB4): if the heatsink’s temperature is below 25°C (77°F), the fans are turned off. Between 25°C (77°K) and 55°C (131°F), fan speed increases with rising heatsink temperature; above 55°C (131°F), they run at full speed.
Clubmax FB4, Atom and Spectrum series: if the heatsink’s temperature is below 15°C (59°F), the fans are turned off or run at low speed. Within the range of 15°C (59°F) to 33°C (91°F), fan speed increases with rising heatsink temperature, and above 33°C (91°F), they run at full speed.

Yes, it is OK. Kvant Atom and Spectrum projectors use multi-zone fan speed regulation. Fans that cool down warmer sections of the heatsink work at higher speeds. The correct functionality of all fans can be checked at any time by power cycling the projector. After you power up the projector, all cooling fans run at 100% speed for about 2 seconds. Then their speed is adjusted according to the heatsink’s temperature.

A strange noise is usually caused by an object stuck in the fan’s propeller area. It can be a piece of confetti or plastic, or even a hardened mixture of smoke residue and dust. Check the fans, and if you find an obstruction, turn the projector off and remove it.
Another reason for the noisy fans could be a damaged propeller or bearings. If so, replace the fan with a new one of the same type.

In the ILDA operation mode, the shutter is also controlled by the “shutter” signal from an external controller. Check the ILDA cable, especially whether pin #13 is connected properly. We recommend using only original ILDA cables.

If the shutter doesn’t open in any operating mode, please contact your distributor or Kvant Lasers, s.r.o. technical support.

Perform a power cycle procedure by using the mains power switch or unplugging the mains power cable for 5 seconds. After the power cycle, the display should start working correctly.

Check the colour settings in the FB4 menu and make sure all R, G, and B colours are set to 100%.
If the projector doesn’t have a built-in FB4 controller, check the brightness potentiometers at the rear panel - all three should be set to the maximum level.

If all the above is as described and the problem persists, turn off the mains power switch (or disconnect the mains power cord) for 10 minutes. This allows all PSUs to fully discharge and cool down.
After 10 minutes, power up the projector. If overloaded PSUs caused the malfunction, it should now work correctly again.

Check the connection on both ends of the ILDA cable and inspect the ILDA male connector's pins.

Scanned effects can distort when the projector and the PC (controller) are not connected to the same mains power phase because their PE wire potentials (Earth) differ.
Always connect the PC/controller and the laser projector to the same mains power socket when operating in ILDA mode.

Check Master Settings in the FB4 menu and ensure both axis sizes are set to 100%. If the projector doesn't have a built-in FB4 controller, set both X and Y potentiometers on the rear panel to the maximum level.
If all the above is as described and the problem persists, check the ILDA cable connectors on both sides and the ILDA input connector on the projector. One or more of #1, #2, #14, #15 pins may be bent or damaged.
