This dual 1/4 inch jack plate provides essential connectivity for guitar cabinets and PA speaker builds. Musicians building custom cabinets and technicians repairing existing gear rely on these steel plates to handle input connections reliably.

The SAJP511B features two 1/4 inch TS connectors mounted in a durable steel plate, giving you parallel or series wiring options for your cabinet configuration. The metal construction withstands the rigors of live performance environments while maintaining solid electrical connections.

The plate measures 5 3/8" x 3 1/2" overall and requires a 4 1/4" x 2 1/4" cabinet cutout for installation. The black finish matches most professional audio equipment aesthetics. Two TS jacks accommodate standard 1/4 inch instrument cables or speaker cables depending on your application.

Guitar players building extension cabinets use these plates to create parallel connections for multiple speakers. PA technicians install them as input plates on passive speakers or as connection points for bi-amped systems. They work equally well for repair jobs when original plates fail or corrode.

Standard 1/4 inch cables connect directly to both jacks. The plate includes mounting hardware and installs with basic tools. No additional wiring components are needed for most applications.

Seismic Audio backs this jack plate with a one-year warranty. The steel construction delivers the durability professionals expect at a price that makes sense for both custom builds and emergency repairs.

Frequently Asked Questions

What type of cables connect to this jack plate?

Standard 1/4 inch instrument cables or speaker cables connect directly to both TS jacks. The plate accommodates mono 1/4 inch plugs commonly used for guitar speakers and some PA applications. Make sure to use appropriate gauge speaker wire for power handling requirements of your specific application.

Can this jack plate handle high-power PA speakers?

The steel construction and TS connectors are suitable for most guitar cabinet and moderate-power PA applications. For high-power PA systems over 500 watts, verify that 1/4 inch connections meet your power handling needs. Some high-power applications may require Speakon or other heavy-duty connectors instead.

How do I wire the two jacks - parallel or series?

You can wire the jacks either in parallel (for lower total impedance) or series (for higher total impedance) depending on your cabinet design needs. Parallel wiring is more common for guitar extension cabinets. Check your amplifier's impedance requirements before choosing your wiring configuration.

Will this fit my existing cabinet cutout?

This plate requires a 4 1/4" x 2 1/4" rectangular cutout in your cabinet. If you're replacing an existing plate, measure your current cutout first. The overall plate dimensions are 5 3/8" x 3 1/2", providing adequate material around the cutout for secure mounting.

What comes included with the jack plate?

You receive the steel dual jack plate with both 1/4 inch TS connectors installed and basic mounting hardware. You'll need to provide your own speaker wire for internal cabinet connections. Installation requires basic tools and soldering equipment for wire terminations.
