Transrotor Konstant Eins
Overview
The Transrotor Konstant Eins is much more than a simple external power supply: it is a precision generator designed to unlock the full sonic potential of high-end turntables. This regulated power supply addresses a frequently underestimated issue: frequency fluctuations in the mains current, which subtly but continuously degrade the quality of musical reproduction. Designed for the Transrotor Max, Jupiter, Darkstar, and Darkstar Silver Shadow turntables, the Konstant Eins transforms rotational stability into a real, audible, and tangible sonic improvement.
Technology in the Service of Precision
At the heart of the Konstant Eins is its internal generator, which produces a remarkably precise frequency, completely independent of fluctuations in the electrical grid. While standard power supplies are subject to frequency variations of about 5% from the power network, the Konstant Eins generates a stable signal that preserves exact rotational speed.
The technology goes even further with separate amplification for each phase of the dual-phase synchronous motor. This approach ensures the motor receives a perfectly clean signal, optimizing the exploitation of the hysteresis effect in the permanent magnet rotor. The result is smoother, more consistent rotation, improving the wow and flutter characteristics of the turntable.
Speed adjustment of ±5% is achieved via a precision potentiometer, allowing fine, independent tuning for both 33 and 45 RPM speeds. This flexibility meets the needs of demanding audiophiles who wish to compensate for pressing speed variations or finely adjust pitch.
A Design Tailored for the Discerning Audiophile
The aesthetics of the Konstant Eins reflect Transrotor’s philosophy: combining technical performance with visual refinement. The solid aluminum cylindrical housing, hand-polished to a mirror finish, showcases artisanal craftsmanship. This approach goes beyond mere aesthetic appeal: the solid aluminum contributes to electromagnetic isolation and heat dissipation.
The compact dimensions of 85 x 110 mm (height x diameter) allow for discreet integration next to the turntable. The weight of 1.5 kg, substantial for its size, attests to the solid construction and quality of the internal components. The speed selection ring, a central design element, offers intuitive handling and crisp switching between the two speeds.
Compatibility and Simplified Installation
The Konstant Eins is specifically intended for owners of Transrotor turntables equipped with dual-phase synchronous motors. Confirmed compatibility includes the Max, Jupiter, Darkstar, Darkstar Silver Shadow models, as well as the ZET 1 in its single-motor configuration.
Installation requires no modification to the turntable: simply disconnect the standard power supply and connect the Konstant Eins via the rear connector. The external power supply via adapter prevents any electromagnetic pollution of the internal electronics. This modular approach also allows for easy replacement of the adapter in case of failure, without affecting the whole system.
The output voltage of 2 x 18 V AC in two phases matches the specifications of Transrotor motors exactly, ensuring perfect compatibility. The maximum power of 0.2 A and consumption of 15 VA are more than sufficient to power these low-consumption motors.
Technical Features That Make the Difference
The internal architecture of the Konstant Eins reveals several well-considered technical choices. Using an internal generator rather than a simple mains filter ensures complete isolation from power grid disturbances. This approach, more costly in terms of components, guarantees constant stability regardless of local power quality.
Separate amplification of each motor phase prevents interactions between windings and improves the linearity of the motor torque. This technical sophistication, inherited from professional applications, is justified by the pursuit of auditory perfection.
The choice of an external power supply via adapter keeps transformers and their magnetic fields away from the audio chain. This precaution, which may seem excessive, demonstrates the attention to detail in the product’s design.
Frequently Asked Questions
What is the concrete difference compared to the standard power supply provided with my Transrotor turntable? The standard power supply uses the mains frequency directly, with its natural fluctuations of about 5%. The Konstant Eins generates its own stable frequency, eliminating these variations that result in audible speed instabilities, mainly in the bass.
Is the Konstant Eins compatible with my Transrotor ZET 1 turntable? Yes, but only if your ZET 1 is equipped with a single motor. Versions with two motors require a specific power supply capable of driving two units simultaneously.
Can I use the Konstant Eins with a turntable from another brand? No, the Konstant Eins is specifically designed for Transrotor dual-phase synchronous motors. The connectors and electrical characteristics are proprietary to this brand.
How do I precisely adjust the speed with the Konstant Eins? A precision potentiometer allows for ±5% adjustment for each speed. Use a stroboscope or tachometer to measure the exact speed and adjust according to your preferences or the record’s specifications.
What is the difference compared to the more expensive M1 Reference model? The M1 Reference offers an even purer sine wave and superior performance, particularly in terms of motor stability and bass definition. The Konstant Eins is an excellent performance/price compromise for getting started.
