The SA-PLATE35 stainless steel wall plate streamlines permanent audio installations for studios, venues, churches, and commercial spaces. This 3-gang wall plate consolidates six XLR/quarter-inch combo connections into a single professional mounting point.

Each combo connector accepts both XLR and 1/4" TRS/TS plugs, giving you maximum flexibility for microphones, instruments, and line-level signals. The dual-input design eliminates the need for separate wall plates or adapters when connecting different signal types.

Built with stainless steel construction and measuring 4.5" x 6.375", this wall plate fits standard 3-gang electrical boxes and mounts securely with included screws. The connectors attach with screws rather than rivets, making field service and repairs straightforward. Six combo jacks provide enough I/O for multi-zone sound systems, recording booths, or stage boxes.

Perfect for recording studios that need mic and instrument inputs at talent positions, houses of worship routing choir mics and instrument feeds, or conference rooms connecting multiple audio sources. Commercial venues use these plates for permanent stage snake connections and distributed audio systems.

Installation requires standard 3-gang electrical boxes and appropriate audio cables. The plate includes mounting hardware, and all six combo connectors are ready to accept standard XLR and quarter-inch connections immediately.

Seismic Audio backs the SA-PLATE35 with a one-year warranty and ships directly to your installation site. Professional-grade permanent installation hardware that simplifies complex audio routing.

Frequently Asked Questions

What's the difference between XLR and 1/4" combo connectors?

Combo connectors accept both XLR (3-pin) and 1/4" TRS or TS plugs in the same jack. This means you can plug in microphones using XLR cables or instruments and line sources using quarter-inch cables without needing separate connectors. Each of the six jacks on this wall plate handles both connection types.

Does this wall plate fit standard electrical boxes?

Yes, the SA-PLATE35 is designed for standard 3-gang electrical boxes commonly used in construction. The plate measures 4.5" x 6.375" and includes mounting screws. You'll need a 3-gang electrical box installed in your wall, which electricians typically install during construction or renovation.

How many audio sources can I connect to this wall plate?

This wall plate provides six independent combo connectors, so you can connect up to six different audio sources simultaneously. Each connector is isolated, meaning you could run six microphones, six instruments, or any combination of XLR and 1/4" sources through a single wall location.

Can I repair or replace individual connectors if one fails?

Yes, the connectors are attached with screws rather than rivets, making them field-serviceable. If a connector develops issues, you can remove the mounting screws and replace just that connector without replacing the entire wall plate. This design reduces long-term maintenance costs for permanent installations.

What gauge wire should I use behind this wall plate?

The wall plate itself doesn't specify wire gauge requirements since it's a passive connection point. Your wire gauge depends on the cable runs and signal levels you're carrying. For most professional audio applications, 22-24 AWG shielded cable works well for line-level signals, while microphone runs may use heavier gauge depending on length and phantom power requirements.
