Premier Manufacturer
For every live performance, reliable connections are as essential as the musicians.
Custom stage audio cable assemblies ensure that cables meet your exact needs on stage, featuring the right connectors, lengths, and a rugged design.
At Romtronic, our custom audio cable assemblies enable professional sound engineers and AV integrators to focus on the show, not on cable failures.
In technical terms, a custom cable assembly is a grouping of wires configured to carry signals or power from one point to another. In plain terms, we manufacture cables that connect point A to point B, carrying signals exactly as you specify. This means the length, wire gauge, shielding, and connectors match your gear. The result? Fewer connection headaches, cleaner sound, and a stage that runs smoothly.
Key Benefits of Custom Cable Assemblies
- Precise Fit and Flexibility – Tailored lengths and connector types (XLR, TRS, SpeakON, etc.) mean no dangling slack or forced angles on stage.
- Optimal Signal Quality – Properly balanced circuits and high-quality shielding prevent noise and interference, keeping your mix crystal clear.
- Enhanced Durability – We select robust materials (PVC, TPE, metal connectors) and incorporate strain relief to ensure cables withstand the rigors of live touring.
Types of Stage Audio Cable Assemblies
Professional stage setups use a variety of cable types. Our factory builds cables for microphones, instruments, speakers, and lighting controllers. Here are some common examples:
| Cable Type | Typical Use | Connector |
|---|---|---|
| XLR Audio | Balanced mic and line audio | 3-pin XLR (male/female) |
| 1/4″ TRS | Balanced line/instrument audio | 1/4″ TRS (stereo/mono) |
| SpeakON | Amplifier-to-speaker connections | Neutrik NL2/NL4 twist-lock |
| DMX Lighting | Stage lighting control (512 channels) | 5-pin XLR (digital) |
| Headphone | In-ear monitors and personal mixes | 1/4″ or 3.5mm TRS |
We build a vast range of cables, including XLR, TRS, RCA, DMX, instrument, speaker, headphone extensions, patch cables, & more. Our XLR assemblies utilize precision soldering on high-quality connectors, making them ideal for balanced microphone signals. Our custom TRS cables are designed for use with guitars, keyboards, or stereo line devices. For speakers, we offer SpeakON speaker cables with Neutrik connectors – the industry standard in professional audio. These twist-lock SpeakON cables are known to be safe and much more reliable than basic 1/4″ speaker plugs.
Lighting control uses DMX cabling. We build these with 5-pin XLR connectors and 110Ω-rated cable (versus ~45Ω on mics), ensuring reliable digital signaling. Every DMX cable carries up to 512 channels per run, so we pay special attention to shielding and termination. By offering all these cable types (and even multichannel snakes or custom adapters), we cover every connection need on stage.
Quality and Certifications
A cable is only as good as its components and the testing that goes with them. Romtronic’s assemblies carry the quality marks you expect. We use UL-certified cable and components (safety-tested). We also use CE-marked jackets for the European market. All our wiring is RoHS-compliant (no hazardous substances), and we operate under ISO 9001 quality standards. Here’s a quick overview:
| Certification | Purpose |
|---|---|
| UL | US safety (rigorous electrical/fire testing) |
| CE (CPR) | EU safety/health/environment requirements |
| RoHS | Restricts hazardous substances in electronics |
| ISO 9001 | International quality management standards |
Meeting these certifications means our cable assemblies are safe, reliable, and consistent. It’s peace of mind for AV professionals: a certified cable won’t unexpectedly fail or introduce noise on stage. We also perform 100% continuity and impedance testing on every assembly before shipping.
Custom Solutions for AV Integrators and OEMs
Romtronic specializes in working with AV integrators and OEM equipment manufacturers. If you’re building a custom audio system or integrating gear into a venue, we understand your needs. You can request unique requirements, such as special cable colors, printed labels, custom lengths, or multiplexed harnesses. Our team can even suggest special materials (flame-retardant jackets, low-smoke cables) for large installations.
For OEM projects, our factory handles both volume production and one-off builds. We maintain a broad inventory of connectors and conductors, ranging from basic XLR to fiber-optic and industrial interfaces, which enables us to offer fast lead times. Imagine specifying 50 custom XLR-TRS combo cables for a console integration – we’ll handle the design, assembly, and testing. We speak your language (and our cables speak your signals).
