Product Description
RDL STA-1 Electronic Transformer/Line Amplifier
Overview
The STA-1 is a high quality, miniature wall and surface mount, dual-channel audio electronic line transformer and amplifier from RDL, designed for use in situations where balanced/unbalanced configuration conversion and level boost are required.
The input accepts either high or low impedance, balanced or unbalanced signals. The output will drive into either high or low impedance loads, connected either balanced or unbalanced.
