RDL STA-2A Dual High Gain Line Amplifiers

Optimize audio clarity and level control across security, surveillance and pro-audio systems with the Radio Design Labs STA-2A dual high-gain line amplifier. Designed as a pro amplifier for installers and integrators, the STA-2A delivers low-noise, wideband amplification with precision trimming — allowing you to match source levels with unity to +24 dB of gain for consistent monitoring and recording. Each of the two identical channels accepts balanced or unbalanced inputs and drives long balanced audio runs into 600 Ω loads, minimizing degradation across distance. The STA-2A’s wide frequency response (10 Hz–100 kHz) and low distortion maintain intelligibility for security and surveillance recordings as well as clarity for broadcast and AV distribution. RDL’s SupplyFlex power input supports 24 VDC or bipolar supplies (±12/±15 VDC), making the amplifier simple to deploy in low-voltage and redundant-power environments. Ideal for CCTV audio, monitoring rooms, public address and distributed audio installations — add the STA-2A to your system to improve signal integrity and reliability.

• Dual independent channels for flexible signal distribution and easy integration into multi-zone security or monitoring systems
• Precision gain control (unity to +24 dB) for consistent level matching and low-noise amplification
• Wideband, low-distortion design (10 Hz–100 kHz) that preserves audio clarity for surveillance, broadcast and AV monitoring
• Robust line drivers that drive long balanced lines into 600 Ω loads, reducing signal loss across large installations
• SupplyFlex power compatibility (24 VDC or bipolar ±12/±15 VDC) simplifies low-voltage deployments and redundancy planning
