Microprocessor TLGR Meter
The CP523V is equipped with Microprocessor True Level Gain Reduction Meter.
This is a unique approach to provide the user with an ultra-accurate gain reduction reading. In most of the Compressors, the gain reduction is measured using the indirect method with an additional LDR circuit or by measuring the Side-chain voltage.
The RVGR is based on a microcontroller that 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.

HRK Active Transformer
Bart Hrk has developed a proprietary design for an Active Transformer, aimed at addressing the limitations of traditional passive transformers.
Traditional passive transformers are known to be vulnerable to electromagnetic interference, such as 50/60Hz hum and HF RF smog. Additionally, their frequency response is contingent upon load and source impedance, which adversely affects the overall performance of analog studio equipment.
The HRK Active Transformer is a game changer that not only resolves the issues associated with passive transformers but also retains and amplifies the desired characteristics of the transformer output stage. This includes the enrichment of harmonic content and the enhancement of tonal response.
What sets the HRK Active Transformer apart is its ability to deliver the rich, beloved sound that audio enthusiasts seek, including the harmonic content and tonal response, while simultaneously eliminating the drawbacks of passive transformers.
Furthermore, the Active Transformer introduces a delicate “Air” effect and boasts an extended low-frequency (LF) performance, adding depth and clarity to the sound.
Another remarkable feature of the Active Transformer is its dynamic saturation, which is dependent on the output level. As the output signal level increases, the Active Transformer exhibits greater saturation, reminiscent of the warm and rich sound produced by classic studio equipment.
In summary, the HRK Active Transformer is an innovative solution that offers superior sound quality, eliminates electromagnetic interference, and enhances harmonic content and tonal response. It is an invaluable asset for professionals and audiophiles seeking to elevate their audio experience.
The CP523V Gain Makeup Stage is made with a Pro-Audio Grade tube, which delivers superb specification matching and a much longer operating time compared to standard thermionic valves.
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 side-chain controls are simple and powerful providing the necessary tools for many demanding studio applications.
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.
Note:
Clips below show the old silver plate version of the CP523V. The balck front panel version has the same sonic performance.
Stereo Buss Operation
- Our improved production process ensures stereo matching between units
- If you purchase two units in one order, both units are matched for stereo operation, bus processing and mastering.
