The SA-PLATE28 stainless steel wall plate brings professional XLR connectivity to permanent installations in recording studios, live venues, churches, and broadcast facilities. Audio technicians and installers rely on this dual-connector solution to create clean, accessible connection points for microphones, line signals, and balanced audio runs.

This wall plate provides two female XLR connectors in a standard electrical box format, eliminating cable clutter and protecting connections from damage in high-traffic areas. The serviceable XLR connectors ensure long-term reliability — if a connector fails, you can replace it without rewiring the entire installation.

Built from stainless steel construction measuring 4.5" x 2.75", the SA-PLATE28 delivers durability that withstands daily use in professional environments. The silver finish maintains a clean appearance that complements any studio or venue aesthetic. Each connector meets professional audio standards for signal integrity and mechanical reliability.

Recording studios use these plates for patch bay extensions and artist headphone feeds. Live venues install them at stage edges for quick microphone connections. Churches position them at podiums and instrument areas for seamless audio integration. The standard electrical box mounting simplifies installation in existing wall cavities.

Installation requires standard electrical box preparation — the plate mounts directly over single-gang boxes using included screws. Connect your audio cables to the rear terminals for permanent runs to mixing consoles, interfaces, or distribution systems.

Seismic Audio backs the SA-PLATE28 with a one-year warranty and fast shipping. Professional installation hardware that works the first time and keeps working.

Technical Specifications

Frequently Asked Questions

What electrical box size does this wall plate fit?

The SA-PLATE28 mounts over standard single-gang electrical boxes, the same size used for light switches and outlets. The 4.5" x 2.75" dimensions provide proper coverage and secure mounting. Installation follows standard electrical box procedures, making it familiar territory for any installer or electrician.

Can I replace the XLR connectors if one fails?

Yes, the XLR connectors are fully serviceable, meaning you can remove and replace individual connectors without replacing the entire wall plate. This design reduces long-term maintenance costs and minimizes downtime in professional installations. Simply disconnect the rear terminals, remove the failed connector, and install a replacement.

What's the difference between this and using XLR barrel connectors?

Wall plates provide permanent, protected installation compared to barrel connectors that can work loose or get damaged. The stainless steel construction and recessed mounting protect connectors from impact damage and cable stress. Wall plates also deliver cleaner aesthetics in professional environments where appearance matters.

How do I connect cables to the back of this wall plate?

The rear of each XLR connector features standard solder terminals or screw terminals for permanent wire connection. You'll connect your audio cables (typically 22-16 AWG) to pins 1, 2, and 3 on each connector following standard XLR wiring conventions. Ensure proper strain relief for cables entering the electrical box.

Is this suitable for phantom power applications?

Yes, the SA-PLATE28 handles standard phantom power (48V) applications commonly used with condenser microphones. The professional-grade XLR connectors maintain proper signal integrity and safety standards for phantom power distribution. Always verify your specific phantom power requirements and follow proper grounding procedures during installation.
