The SA-PLATE20 stainless steel wall plate delivers permanent audio connectivity for studios, venues, and installations requiring dual 1/4" TS mono connections. Professional installers and facility managers choose this plate for clean, permanent audio routing without exposed cables.

This wall plate provides two independent 1/4" TS mono jacks for connecting instruments, microphones, or line-level sources directly through the wall. The stainless steel construction resists corrosion and maintains professional appearance in high-traffic environments.

The plate measures 4.5" x 2.75" and fits standard electrical boxes, making installation straightforward for any electrician or AV technician. High-quality connectors ensure reliable signal transfer without noise or intermittent connections. The silver finish matches professional rack gear and studio aesthetics.

Studios use these plates for permanent instrument connections, allowing musicians to plug directly into wall-mounted jacks that route to the control room. Churches and venues install them for microphone drops, instrument inputs, and monitor feeds. The dual configuration handles stereo instruments or two separate mono sources.

Installation requires only a standard electrical box and the included mounting screws. Standard 1/4" TS cables connect directly to the front-facing jacks. The plate accepts any standard 1/4" TS connector from guitars, keyboards, microphones, or line-level devices.

Seismic Audio backs the SA-PLATE20 with a one-year warranty and ships ready for immediate installation with mounting hardware included.

Technical Specifications

Frequently Asked Questions

What types of audio equipment can I connect to this wall plate?

The SA-PLATE20 accepts any device with a standard 1/4" TS mono output, including electric guitars, bass guitars, keyboards, synthesizers, microphones with 1/4" outputs, and line-level audio equipment. Each jack is independent, so you can connect two separate mono sources or use both jacks for a single stereo instrument. The TS configuration is specifically designed for mono signals and instrument-level connections.

How do I install this wall plate in my studio or venue?

Installation requires a standard electrical box (single gang) and basic electrical skills. Mount the electrical box at your desired location, run your audio cables to the box, connect the cables to the back of the wall plate jacks, and secure the plate with the included mounting screws. The 4.5" x 2.75" dimensions fit standard electrical boxes used in residential and commercial construction.

Can I use this wall plate for microphone connections?

Yes, this wall plate works well for microphone connections, particularly for permanent installations where you need wall-mounted mic inputs. However, note that these are TS (tip-sleeve) mono jacks, not XLR, so you'll need microphones with 1/4" outputs or appropriate adapters. This setup is common in churches, conference rooms, and performance venues for fixed microphone positions.

What's the difference between TS and TRS connectors for this application?

TS (tip-sleeve) connectors carry mono unbalanced signals, making them ideal for instruments like guitars and keyboards, as well as mono microphones. TRS (tip-ring-sleeve) connectors handle balanced mono signals or stereo signals. This SA-PLATE20 uses TS jacks specifically for mono instrument and line-level connections. If you need balanced connections, consider our TRS wall plate options.

How many venues or rooms can benefit from permanent wall plate installations?

Wall plates work well in any space where you regularly connect audio equipment in the same locations. Recording studios use them for instrument tracking rooms, churches install them for altar microphones and instrument connections, and venues use them for stage monitor feeds and FOH connections. Even home studios benefit from wall plates to eliminate cable clutter and create permanent connection points for frequently used equipment.
