Cloud TRUE BLUE CL-520 500 Series Precision Microphone Preamp

The Cloud True Blue CL-520 is a 500 Series microphone preamp born from collaboration between Cloud Microphones and True Systems. It delivers 76dB of straight–wire gain with a patent–pending Cloud Touch Interface for signal switching. What sets it apart is the ability to capture your microphone's true character—exceptional depth and clarity without the sterile quality that plagues many clean preamps.

Built on a fully balanced topology, the CL-520 exhibits extremely low THD+N, wide bandwidth, and snappy transient response across the frequency spectrum. A +16 button activates the final 60dB–76dB range for low–output mics, while a variable highpass filter adjusts from 25Hz to 420Hz at 6dB/octave. Dedicated Dynamic/Ribbon mode optimises impedance for passive mics, and a polarity–reversal button corrects phase relationships in multi–mic recording scenarios. The unit includes +48–volt phantom power for condenser microphones.

Session engineers and home recordists benefit from the thoughtful design: high–grade telecom relays ensure precise switching reliability, and the gain staging accommodates everything from ribbon mics to condensers without compromise. Whether tracking vocals in a bedroom setup or layering instruments in a professional studio, the True Blue CL-520 maintains signal integrity and delivers what your mic actually captures.
