ST-GLA1

RDL ST-GLA1 - Gated Line Amplifier - Noise Gate

The RDL ST-GLA1 is a professional gated line-level amplifier designed for automatic audio switching with built-in noise reduction. The module activates when audio is present and mutes when silent, effectively suppressing unwanted background noise. This makes the ST-GLA1 ideal for mixing systems, intercoms, paging setups, and any application requiring clean and intelligible audio.

It can be used standalone as a noise gate or integrated into automatic mixing systems. The open-collector logic output allows triggering of external devices or other RDL modules, enhancing system flexibility.

Inputs and outputs can be wired as balanced or unbalanced. Two LED indicators assist in precise adjustment of gain and threshold settings.
