We have optimized and improved the tube simulation part of DSP and  reduced CPU consumption in the latest update. This allows for more precise tube sound and better workflow. We've also added an UI zoom option and extended support for the latest operating systems and DAWs,  including full Apple Silicon compatibility .

The middle knob of RZ062A rotates the frequency curve around the central point of 650 Hz. When the bass frequencies are raised, the trebles are simultaneously lowered and vice versa. 

The RZ062 works bit differently. Its presence knob lets you choose one of four frequencies (1.4, 2, 2.8, and 4 kHz) and adjust their gain independently. This parameter helps your sonic material to cut through very gently.

To create RZ062 , we had to emulate more than 200 circuit components. These highly precise analog circuits made the original units so special . For RZ062, we used so-called “white box modeling.“

The RZ062 Equalizers were designed in Germany almost 60 years ago for installation in mixing consoles, together with the U73b compressors and other ingenious valve-based modules of that time.

They were used in European studios to perform modification of frequency characteristics of the recorded sound to eliminate undesired studio acoustics. But their complex valve circuits bring something much more interesting than just basic equalization: The incredibly subtle sound color, which is highly valued in modern recording projects.
