Professional microphone cable by the spool for installers, sound engineers, and anyone building custom cable runs for permanent installations. The SA-MIC500 delivers 500 feet of quality 3-conductor cable ready for termination with your choice of connectors.

This balanced and shielded cable handles professional microphone signals without noise or interference, letting you create exact-length runs for clean installations. The 22-gauge dual copper conductors provide reliable signal transmission over long distances.

Built with 3-conductor construction for balanced XLR connections, complete shielding to reject electromagnetic interference, and a flexible PVC jacket that routes easily through conduits and cable trays. The 22-gauge wire size handles microphone-level signals with proper impedance characteristics for professional audio applications.

Install permanent microphone runs in churches, theaters, conference rooms, and recording studios. Create custom-length microphone cables for touring rigs where standard lengths don't fit your setup. Route microphone feeds from stage boxes to mixing positions in venues where pre-made cables fall short or create clutter.

This is raw cable only — you'll need XLR connectors and basic soldering skills to terminate your custom lengths. The spool format makes it easy to measure and cut exact lengths without waste.

Seismic Audio backs this microphone cable with a one-year warranty. Ships ready to terminate for your specific installation needs.

Frequently Asked Questions

What connectors do I need to terminate this microphone cable?

You'll need male and female XLR connectors to create standard microphone cables. The 3-conductor design works with any quality XLR connector — connect pin 1 to shield, pin 2 to positive conductor, and pin 3 to negative conductor. Basic soldering skills are required for proper termination.

How long can I run microphone cable without signal loss?

Professional microphone cable can typically run 100-300 feet without noticeable signal degradation, depending on the microphone output level and preamp sensitivity. This 500-foot spool gives you flexibility for even the longest permanent installations in large venues or multi-room facilities.

Is this cable suitable for outdoor installations?

The flexible PVC jacket provides good protection for indoor installations, but for permanent outdoor runs, consider additional conduit protection. The cable itself handles temperature variations well, but UV exposure and moisture require proper installation practices for long-term reliability.

Can I use this cable for other audio signals besides microphones?

While designed for microphone-level signals, this balanced cable works for any low-level audio application including line-level connections between mixing consoles, effects units, and other professional audio gear. The balanced design and shielding make it suitable for any application requiring noise-free signal transmission.

How much cable do I need for a typical installation?

Plan for 20-30% extra beyond your measured distances to account for routing around obstacles, service loops, and termination length. A 500-foot spool typically handles 8-12 microphone positions in a medium-sized venue, depending on the distance from stage to mixing position.
