Why Choose the Stagg SIA-ST?
If you want the benefits of in-ear monitoring without investing in a full wireless system, a wired belt-pack style amp like the SIA-ST is a very practical option. You can take a monitor send from the desk, run it into the dual XLR inputs, set mono or stereo as needed, and control your own listening level directly from the unit.
It’s small enough to clip or sit close by on stage, and being battery powered means you’re not hunting for an extra mains outlet at every gig. For drummers, keyboard players, guitarists using modelers, or anyone on a mostly static position, it’s a simple way to move from wedges to in-ears while keeping the setup easy to understand.
