The STA-2A Dual High-Gain Line Amplifier from RDL is a dual-channel, line-level audio preamplifier with up to 24 dB gain. The gain is adjustable from unity to +24 dB using a 25-turn precision audio taper trimming potentiometer.

Each channel is identical and audio inputs are bridged at 20 kOhms to accept either balanced or unbalanced audio signals. The STA-2A's output and line-driver circuits are designed to drive long balanced audio lines into 600-Ohm loads. This unit features wideband circuitry for excellent phase response and improved clarity.

It offers RDL's SupplyFlex power input configuration that can be fed from a ground-referenced 24 VDC power supply, a floating (non-ground-referenced) 24 VDC power source, or a bipolar power supply.

Note:
Power supply available separately
