Bettermaker Valve Stereo Passive Equalizer (VSPE) is a breakthrough in audio engineering, combining the timeless warmth of vacuum tube technology with the precision of digital recall. Years of meticulous development and testing have culminated in a product that promises to revolutionize your sound.
STEREO/ DUAL MONO Passive Equalizer with Tubes and Transformers
New Heat audio circuitry provides warmth and rich harmonics
Handcrafted HQ Audio Transformers made by Bettermaker
New intuitive DAW plugin including mastering HPF, LPF and band Audition engine
Drawing on their expertise in Grammy award-winning studio processors, Bettermaker has crafted a fully analog passive equalizer featuring original vacuum tube and transformer circuitry. But they didn’t stop there. Bettermaker has integrated their own handcrafted audio transformers from Bettermaker, ensuring unparalleled quality and performance.
Passive equalizers are renowned for their ability to impart a round, warm bottom end and an airy high-frequency range. Now, imagine enhancing that richness with the unmistakable character of vacuum tubes and transformers. That’s the essence of HEAT, Bettermaker’s signature sound.
With it’s innovative design, you can effortlessly balance between pristine vacuum tube transparency and the lush saturation of tubes and transformers with the press of a button. And thanks to seamless integration with Bettermaker’s plugin and DAW, you can recall and automate settings with ease.
Speaking of plugins, Bettermaker’s new VSPE plugin takes versatility to new heights. Not only can you recall and automate all parameters within your DAW, but you can also audition high and low frequencies independently. Plus, with stereo and dual-mono modes at your fingertips, the possibilities are endless.
Bettermaker’s plugin features a mastering-grade digital high-pass and low pass filters, perfect for sculpting your low and high end with precision.
Whether you’re recording, tracking, producing, mixing, or mastering, the VSPE offers unparalleled flexibility and sonic character in a single, elegant package. Experience the best of both worlds with the VSPE: where vintage warmth meets cutting-edge technology.
The tubes used in Bettermaker devices were produced in the USSR in the 70s and 80s exclusively for the needs of the military and were intended for use in the electronics of ballistic missiles and military jet fighters. Meeting very strict requirements in terms of durability and electrical parameters, they have been designed in such a way as to minimize the phenomenon of microphonics and ensure very high parameters even after a long period of use. This is one of the few Tubes in which attention was paid to the extremely low level of noise and distortion. Each tube that left the factory then, was selected during strict tests of all parameters and has an individual military acceptance stamp.
The tube type is a double triode with a screen between the two triodes. Maximum convergence of the parameters of two triodes plus extremely low capacitance between them – below 0.1pf. Precious metal alloys and special gases used to eliminate lamp vibration noise.
The decision to create their own transformers wasn’t born out of a lack of options in the market. There’s no shortage of professional-grade products available, with many claiming to offer top-tier performance. However, upon comparing them to classic, renowned transformers, the disparity becomes evident.
Having worked extensively with over a hundred different vintage transformers from esteemed manufacturers like Siemens (for WSW, Telefunken, military), Collins, Marinair, UTC, Malotki, Soviet military, and others, the differences are not just audible but measurable. One of the most glaring issues arises in the lower frequency range, where distortion levels can be significatly higher than at 1kHz.
While frequency response might appear adequate, the coherence of the sound in the lower range often falls short of musical expectations. To cut a long story short, after years of rigorous research and collaboration with core manufacturers, Bettermaker has finally developed a transformer that satisfies us on multiple fronts—as musicians, a sound engineers, and an electronics developers.
Bettermaker Valve Stereo Passive Equalizer is delivered with hybrid DAW plugin that allows you to control and recall all settings of the hardware. Additionally provides high quality digital HPF and LPF, spectrum analyzer, session snapshots and other useful functions such as dual mono operation, audio level metering and quantize (step) mode for all hardware knobs. You can also adjust VSPE filters by draging handles on the EQ curve graph. Currently selected band will be solo’ed to let you hear the changes.
Please note that some hardware features are available only when DAW plugin is connected and active. In standalone mode VSPE will link both channels and disable quantize mode. HEAT function is always linked, regardless the link mode or channel selected
