Radio Design Labs STA-1

<h4>Dual Bal/Unbal Line Amp: -12 to 20 dB Gain</h4><p>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.<br /><br />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.<br /><br /><b>Features:</b><br />&bull; Up to 20 dB Gain in an Audio Line<br />&bull; Conversion from Balanced to Unbalanced<br />&bull; Conversion from Unbalanced to Balanced<br />&bull; Conversion from High to Low Impedance<br />&bull; Conversion from Low to High Impedance
