The RDL STA-1M is a versatile single-channel audio line amplifier engineered for professional applications requiring clean, precise signal amplification and bridging. This module accepts balanced or unbalanced inputs, handles high- or low-impedance sources, and delivers outputs that can drive balanced or unbalanced lines with low distortion and high fidelity.
The STA-1M features an instrumentation-style input stage, isolating ground loops while amplifying differential signals. It also provides flexible impedance conversion, including high-to-low and low-to-high, and allows bridging of audio lines to avoid loading. Its output supports precise level matching for seamless integration into larger audio systems.
Equipped with RDL SupplyFlex™ power input, the STA-1M can operate from floating 24 Vdc, bipolar ±12 Vdc/±15 Vdc, or ground-referenced 24 Vdc power sources, ensuring reliable performance in diverse installations.
