Dual High Gain Line Amplifiers 7 Year Warranty
The STA-2A is a dual-channel line-level audio preamplifier. Each channel is identical. The audio inputs are bridged at 20 kΩ and accept either an unbalanced or a balanced audio signal. Gain is adjustable from unity to +24 dB using a 25-turn precision audio taper trimming potentiometer. The output line driver circuits are designed to drive long balanced audio lines into 600 Ω loads.
The STA-2A features wideband circuitry for excellent phase response low noise low distortion and exceptional audio clarity. RDL's SupplyFlex power input configuration is included in the STA-2A. The power supply input may be fed from a floating (not ground-referenced) 24 Vdc power source from a bipolar power supply (+/- 12 Vdc or +/-15 Vdc) or from a ground-referenced 24 Vdc power supply.
Many audio products provide optimum performance when feeding into a bridging input but may not provide the output needed to directly drive low-impedance lines terminated with 600 ⦠transformers. The STA-2A is specifically designed for such installations and is also ideal in installations requiring high gain in line-level audio transmission.
Features:
• Up to 24 dB Gain in Audio Lines
• Conversion between Unbalanced and Balanced
• Conversion between High and Low Impedance
• Low-Impedance High-Current Line Drivers
• Dual-Channel Line-Level Preamplifiers
• High Gain High Output High Performance
• RDL® SupplyFlex™ Power Input Configuration
