Radio Design Labs STA-1

Dual Bal/Unbal Line Amp: -12 to 20 dB Gain

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
