The STA-2A Dual High-Gain Line Amplifier from RDL is a dual-channel line-level audio preamplifer. This unit offers up to 24dB gain in audio lines. Conversion between balanced and unbalanced audio is possible, as is conversion between high and low impedance.

Each channel is identical and audio inputs are bridged at 20Ω to accept either balanced or unbalanced audio signals. Its output line driver circuits are designed to drive long balanced audio lines into 600Ω loads. This unit features wideband circuitry for excellent phase response and improved clarity.

Also included with this model is RDL's SupplyFlex power input configuration. It may be fed from a ground-referenced 24VDC power supply, a floating (non ground-referenced) 24VDC power source, or a bipolar power supply.
