TRUE BLUE 520 Precision Mic Preamp

The CL-520 is a next-generation microphone preamp created through a collaboration between Cloud Microphones and True Systems, combining Cloud's relentless focus on high-quality, low-noise gain staging with True Systems' 20+ years in high-end studios, live sound, and post-production environments.

Designed for stunning musical accuracy, the TRUE BLUE 520 captures sound with exceptional depth, clarity, and dimensionality without relying on coloration or exaggerated character. Its fully balanced topology provides outstanding low THD+N, wide bandwidth, and fast transient response, ensuring reliable signal integrity in any recording environment.

What you hear is what you capture. Focus on the performance, the mic placement, the source. The TRUE BLUE 520 delivers exactly what's in front of the microphone.


Performance Features:

- Extended 76 dB gain range
- Musically tuned variable high-pass filter
- Dedicated Dynamic and Ribbon Mode with optimized impedance and signal path for passive microphones
- Cloud Touch Interface (patent pending) activate high-grade telecom relays for precise, reliable signal switching
- The TRUE BLUE 520 is engineered to sound finished from the source: record-ready.


Capacitive Touch Controls:

+16: Adds +16dB of gain, extending the preamp's maximum gain from 60 dB to 76 dB for low-output microphones.

Phase: Inverts signal polarity by 180° to correct phase relationships when using multiple microphones.

HPF: Enables a variable 6 dB/octave high-pass filter adjustable from 25 Hz to 420 Hz.

48V / Dyn RIB: Engages 48V phantom power for condenser microphones. When disabled, Dynamic Ribbon Mode is automatically enabled, removing input capacitors and increasing input impedance from 5 kΩ to 10 kΩ for optimal dynamic and ribbon mic performance.
