Lighting and control
Ayrton Cobra
Identify Cobra and its revision before preparing patch, control source and zoom behavior; preserve operating limits.
Ask GLMedia about renting Ayrton Cobra for your event. Availability and configuration are subject to confirmation.
Model and purpose
- Manufacturer
- Ayrton
- Model
- Ayrton Cobra
- Model
- Cobra 014170; distinct from Cobra²
- Optics
- Laser-phosphor source; motorized 0.6°–23° zoom
- Power
- 100–240 VAC, 50/60 Hz; 480 W maximum
- Control
- DMX/RDM, CRMX, Art-Net and sACN
A moving head for narrow beams, gobos and prism effects, with CMY mixing, CTO and continuous rotation. Its effects require assessment of beam paths and exposure before enabling output. Source classification does not remove precautions for the emitted light.
Prepare your rental inquiry
- Date, city, venue and setup, event and pickup schedule.
- Intended use, area dimensions and equipment already supplied by the venue or production.
- Desired effect, positions, throw, area and stage restrictions.
- Control profile, mounting accessories and camera coordination where needed.
Specify equipment only or whether setup, programming, operation and strike are also needed. Scope is confirmed in the proposal.
You do not need a final equipment list: tell us the result you want and the part you need help with. Availability and scope are confirmed in the proposal.
Features and connections
5-pin XLR carries DMX and RJ45 carries network data; TRUE1 TOP In / Out carries power. Select signal source, universe and personality at the fixture as well as the console.
Beam, Spot and Special are Zoom Mode options. Zoom value and optical mode work together; a palette can project differently after changing these settings.
Filters, gobos, prisms and frost are available; a Profile framing-blade system is not included. Check each effect against Cobra documentation.
Prepare the system
- Confirm Cobra, regional revision, firmware and DMX chart. Clear movement and release transport locks; qualified personnel must handle mounting and retention.
- In Address, select source, universe and address; in Mode, match Basic, Standard or Extend to the console personality. User modes can reorder channels.
- Record Illumination Limit, Beam Mode, Prism Mode, CTO Control and signal-loss behavior. Do not enable emission before paths, distances and exposure are assessed for the application.
Questions and troubleshooting
Does zoom differ from a palette or appear limited?
Separate zoom position from optical operating mode.
- Compare Zoom Mode: Beam, Spot or Special. Then check Beam Mode and Prism Mode; they can change usable range or effect clipping.
- Check that a palette or control channel is not sending another mode. Do not force motors or change safety limits to regain coverage.
- Zoom Behavior may offer an option named Cobra 2 depending on firmware. It is a behavior setting, not proof that the fixture is Cobra² or shares every capability.
Does CTO fail to respond on the expected channel?
CTO Control determines where correction is controlled in applicable modes.
- Match CTO Control to the personality: it can use the color wheel or a separate channel. Do not assume the same route across profiles.
- Return wheel and mixing to a known reference while preserving intended limits. Match coarse and fine channels to the actual revision’s chart.
- When fixtures differ, record firmware and settings before editing palettes. History includes synchronization changes; this does not establish an update as a tested solution.
Does it move on signal loss, or provide no DMX from network input?
Check signal and recovery functions separately.
- No DMX Status can use Close, Hold or Auto. Sun Protection can tilt the head on signal loss; keep the path clear and do not mistake it for a positioning fault.
- To forward WDMX or Art-Net/sACN through XLR, check DMX Output. A connector does not establish that conversion is enabled.
- Hibernation can cause a reset sequence when DMX returns. Test recovery with controlled output and a clear area before use with an audience.
How should we assess a reference with visible aerial beams?
We can study composition and effect travel, but a festival reference does not guarantee the same result elsewhere. Application distances and exposure must be assessed first.
- Send a reference, plan or photos, approximate heights and distances, audience areas and camera positions. If atmosphere is part of the design, confirm venue permission and conditions; it is not assumed included or permitted.
- We can compare Cobra for a technically viable effect with light on scenery or visual content if the geometry does not work. Tell us what your production supplies and whether you need equipment, installation, fixture profile and patch adaptation, programming, rehearsal or operation; GLMedia can assess and quote those scopes separately. Any atmospheric effect also needs separate confirmation. Model, availability, quantity and accessories remain subject to confirmation; audience scanning or changing limits to reproduce a video is not offered.
Is it suitable for a precise rectangle of light on stage?
Cobra has gobos and optical effects, but no Profile framing shutters. A narrow beam is not equivalent to adjustable four-sided framing.
- Share shape, approximate size and surface, possible fixture position and ambient light. Assess the effect with the actual optics while retaining existing restrictions; a gobo name alone does not establish a border or shape.
- We can compare a shuttered Profile to define the area with Cobra for effects, or a solution dedicated to the main goal. Equipment, accessories and quantity require assessment; one source is not assumed to perform both tasks.
Can Cobra display a logo, text or a brand animation?
Cobra uses physical gobos and optical effects. Do not assume DMX control can load any image or video, or that a stock gobo reproduces your brand; customization requires specific validation.
- Send the design or a reference, whether it stays fixed or changes during the show, approximate surface and image size, throw and possible positions, ambient light and camera framing. Clarify whether you want an aerial effect or readable content on a surface; these are different goals and remain subject to this page’s usage restrictions.
- We can assess Cobra for textures and effects, another fixture with a specific gobo whose compatibility is documented, or video projection/a screen for variable content. Selection requires reviewing the design and venue: fabrication, content preparation, installation, programming and operation are quoted according to scope, without confirming readability, compatibility or lead times before assessment.
Quick reference
| V125 mode | Footprint | Last possible start |
|---|---|---|
| Basic | 33 channels | 480 |
| Standard | 35 channels | 478 |
| Extend | 45 channels | 468 |
Precautions
- The manual specifies a minimum 25 m to the illuminated surface at narrowest beam and full power. This is not a safe viewing distance or permission for audience scanning.
- Documentation distinguishes Class 1 laser and photobiological RG3. It warns against prolonged viewing closer than 58.3 m; exposure conditions require specific assessment by qualified personnel.
- IP65 and ambient -20–45 °C, with protected connectors and mounting as instructed. Keep direct sunlight out of the lens even when off. Do not open or bypass protection.
