Take control of your in-ear monitoring with the Stagg SIA-ST Personal In-Ear Monitor Amplifier—a compact yet powerful solution for both studio sessions and live performances. Designed for clarity and flexibility, the SIA-ST features dual XLR inputs with switchable mono/stereo operation, allowing you to tailor your mix exactly how you like it.

A 3.5 mm TRS headphone output with balance control lets you fine-tune left/right levels—perfect for compensating for hearing differences between ears. Whether you're tracking in the studio or monitoring on stage, you’ll enjoy reliable performance and great sound.

Power it your way with the included 9V DC adapter, a 9V alkaline battery, or an 8.4V NiMH rechargeable battery—whatever suits your setup.
