Carvin Stagemate S400 Battery Powered Monitor Amplifier Speaker

Carvin StageMate S400 Portable PA System – Made in USA – Fully Functional

Originally purchased 06/26/2009. I removed the 12 volt battery (not included). This also includes the wiring for a 2nd battery, that goes inside the cabinet (that is what is in the baggie in the picture). It also worked well with a 12 volt cable from the cigarette lighter (not included).

This is a rugged, all‑in‑one portable PA system with a built‑in 4‑channel mixer, EQ, effects, and multiple input options. Perfect for small gigs, rehearsals, acoustic sets, public speaking, or as a reliable backup PA. Made in the USA and known for clean headroom and solid build quality.

This unit is fully functional: all channels pass signal, EQ works, effects work, and the power amp is strong. Shows normal wear from light use but nothing that affects performance.
