The SA-APLW80 plate amplifier turns any passive speaker cabinet into a powered PA system. Whether you're building custom DJ monitors, retrofitting existing cabinets, or creating a dedicated sound reinforcement setup, this 60-watt Class AB amplifier delivers the clean power you need.

This plate amp pushes 60 watts RMS (120 watts peak) through Class AB circuitry, providing the headroom and clarity that passive speakers require to perform in live sound applications. The onboard EQ section gives you treble and bass controls plus master volume, letting you dial in your sound without external processing.

Multiple input options handle any source you throw at it — 1/4-inch, RCA, and 1/8-inch connections accommodate everything from mixing boards to smartphones. The RCA line output lets you daisy-chain additional powered speakers or send signal to a subwoofer. Built-in overload and overcurrent protection prevents damage during demanding gigs, while the 115V/230V voltage switch adapts to international power standards.

This amp works well for small to medium venues up to 150 people, making it ideal for coffee shops, small clubs, house parties, or as a stage monitor in larger setups. DJs use these for building compact booth monitors, while bands often retrofit existing cabinets for practice spaces or small gigs.

The compact 9.64" x 4.15" design mounts easily into most speaker cabinets with standard cutout patterns. All input and output connections are included on the rear panel — just add speaker wire to your drivers.

Seismic Audio backs the SA-APLW80 with a one-year warranty and fast shipping direct to your door.

Frequently Asked Questions

What size venue can this amplifier handle?

The SA-APLW80's 60-watt RMS output works well for small to medium venues up to 150 people. This makes it perfect for coffee shops, small clubs, house parties, or as stage monitors in larger setups. For bigger crowds, consider multiple units or step up to higher wattage plate amps.

What cables do I need to connect this amplifier?

The amp accepts standard audio cables — use 1/4-inch instrument cables, RCA cables, or 1/8-inch aux cables depending on your source. You'll need speaker wire to connect the amp's output terminals to your drivers inside the cabinet. The amp doesn't include cables, but all connections use standard audio connectors.

Can I use this to retrofit an existing passive speaker cabinet?

Yes, that's exactly what this plate amp is designed for. The 9.64" x 4.15" footprint fits most standard speaker cabinet cutouts. You'll mount it in the rear panel, connect it to your existing drivers with speaker wire, and transform your passive cabinet into a powered speaker.

How does this compare to buying a powered speaker instead of building one?

Building with a plate amp gives you control over driver selection and cabinet design, often at lower cost than comparable powered speakers. However, it requires woodworking skills and time. If you need plug-and-play convenience, a complete powered speaker is easier, but custom builds let you optimize for your specific needs and budget.

What kind of protection does this amplifier have?

The SA-APLW80 includes both overload protection and overcurrent protection to prevent damage during demanding use. These circuits automatically engage if the amp is pushed beyond safe operating limits, protecting both the amplifier and your connected drivers from damage during loud passages or feedback situations.
