The CP523V is a Tube based fully featured optocompressor with a Class A gain make-up stage. The CP523V has separate controls for Threshold, compression Ratio, Recovery time and Output Gain.
The Attack time can be set with the switch to Fast or Slow. The Slow Attack is perfect for adding the edge to the drums or bass recording.
The Sidechain High Pass Filter removes the low-frequency content from the processing greatly enhancing the capabilities of the CP523V for tracking and mastering.
The CP523V is very musical and easy to use. It can process any music material, instruments, vocal or recordings, delivering amazing results. The Valve – Discrete Transistors Hybrid circuit is the result of a long development process. It produces rich Tube harmonics and tone while maintaining the noise on the extremely low level.
Microprocessor TLGR Meter
The CP523V is equipped with Microprocessor True Level Gain Reduction Meter.
This is a unique approach to provide the user with the ultra-accurate gain reduction reading. In most of the Compressors, the gain reduction is measured using the indirect method with additional LDR circuit or by measuring the Side-chain voltage.
The RVGR is based on a microcontroller which measures the actual level of the signal on the input of the CP523V and the signal level on the output of the compressor stage, in real-time.
Two signal values are compared and the value of the signal reduction is calculated over 400 times every second. The results are averaged and displayed using the Gain Reduction LED Meter.
The typical error of the meter is less than -0.5dB in -1dB to -8dB gain reduction range.

NOS Military Grade Tube
The CP523V Gain Makeup Stage is made with NOS USA Made Military Grade 6U8A tube, which delivers superb specification matching and much longer operating time compared to a standard nowadays made valves.
Create Amazing Results!
The CP523V is easy to use even for engineers with less experience with dynamic processors.
Optocompressors are very versatile and produce smooth compression results. Any music material will benefit from the magic touch added by the CP523V.
The sidechain controls are simple and powerful providing the necessary tools for many demanding studio applications.
Add Harmonics to your Recordings or Tracks
The CP523V is suitable for recording as a part of the signal path.
It will control the dynamics of the signal from the microphone while enhancing the details and structure of the vocal or the instruments. The CP523V can be used for tracking or mastering. Two units can be paired in stereo mode. The Slow Attack mode and the side-chain High Pass Filter can be used very creative way in mastering applications.
Stereo Mode
A pair of CP523V will work in a stereo mode. Two units can be coupled with a special link cable added for free if two CP523V units are purchased.
If you purchasing second CP523V unit simply add the request for the link cable in the information section during the checkout.
The cable will be added to your order for free. The matched CP523V pair is also available as the separate item on this website. More information about how to use CP523V in stereo mode can be found in the User Manual.
Coupled with Custom HRK Transformers
The Output of the CP523V is coupled with specially designed custom HRK Transformers.
Because of limited space in the 500 modules, HRK Custom Transformers became smaller, maintaining no-compromise performance.
All HRK transformers provide the sweet-spot sonic characteristic with pristine detail reproduction.
The goal of the design process was to create the transformer which will deliver a balance between the transparency and colouration typical for transformers.
Discrete Transistor Class A Output Transformer Driver
The output transformer is powered by Class A, No-Feedback, DC-Coupled Discrete Driver.
