CAD Audio PA28 Inline Preamplifier
The CAD Audio PA28 is a compact, high-performance inline preamplifier designed to add clean gain to low-output dynamic or ribbon microphones. It helps improve gain staging for broadcast, podcasting, live performance, and studio use.
This inline preamp provides +28 dB of buffered gain, ensuring that the microphone signal remains strong and consistent even over long cable runs. The PA28 presents a low output impedance and stable level without introducing noise or distortion. Its metal housing ensures durability in active setups.
