RDL STA-1 Stick-On Electronic Transformer/Line Amplifier

The STA-1 is a dual-channel line-level preamplifier with bridging inputs, adjustable gain or loss, and low-impedance outputs. Each of the two identical circuits is both an electronic line transformer and a line amplifier. Hook up the STA-1 just like a pair of audio transformers with gain. True dc amplifiers produce unsurpassed audio clarity, high common-mode rejection, ultra-low distortion and low noise. The STA-1 is perfect for most line amplification, impedance or balanced/unbalanced conversion.The STA-1 operates from floating or bipolar dc power. For installations where ground-referenced power is preferred, use the STA-2A Dual High Gain Line Amplifiers. Features:Up to 20 dB Gain in an Audio Line Conversion from Balanced to Unbalanced Conversion from Unbalanced to Balanced Conversion from High to Low Impedance Conversion from Low to High Impedance Bridge an Audio Line Feed Precisely Match Audio Levels
