Stagg SIA-ST Wired In-Ear Monitor Amplifier – 9V Battery
Take control of your personal monitor mix with the Stagg SIA-ST Wired In-Ear Monitor Amplifier. Designed for musicians who need a simple, reliable and portable way to monitor their performance, the SIA-ST provides a compact solution for live gigs, rehearsals, worship, theatre, studio work and other performance applications.
The SIA-ST features two balanced XLR inputs, allowing you to connect either a stereo monitor feed or two separate mono sources. Its selectable Stereo/Mono operation gives you the flexibility to configure your monitoring setup to suit the performance.
A dedicated 3.5mm TRS headphone output connects directly to your in-ear monitors or headphones, while the volume and balance controls make it easy to adjust your listening level and stereo image. In Mono mode, the balance control can also be used to adjust the level between two connected mono sources.
The SIA-ST is powered by a standard 9V alkaline battery or 8.4V NiMH rechargeable battery, making it a practical choice when you need freedom from mains power. It can also be powered from the included 9V DC power supply when you're working in a fixed location.
Its compact metal housing and lightweight 270g design make it easy to incorporate into a mobile monitoring setup, while the integrated battery-status LEDs help you keep an eye on battery condition. With a frequency response of 20Hz–80kHz, signal-to-noise ratio greater than 90dB (A-weighted) and low 0.01% THD+N, the SIA-ST is designed to provide clean, detailed monitoring.
