Description
RDL STA-2A - Dual High-Gain Line-Level Audio Amplifier
RDL STA-2A is a professional dual-channel line-level audio preamplifier designed for AV installations requiring high gain and conversion between unbalanced and balanced formats. Each of the two identical channels accepts either unbalanced or balanced signals via 20kΩ bridging inputs. Gain is adjustable from unity to +24dB using a 25-turn precision audio taper trim potentiometer.
The output circuits are optimized to drive long balanced audio lines terminated with 600Ω loads. STA-2A features wideband circuitry for excellent phase response, low noise, minimal distortion, and outstanding audio clarity. The module includes RDL’s SupplyFlex™ power input configuration, allowing connection to floating 24Vdc sources, bipolar supplies (+/-12Vdc or +/-15Vdc), or ground-referenced 24Vdc power.
STA-2A is ideal for installations where standard audio devices cannot directly drive low-impedance lines, and where high gain is required in line-level audio transmission.
