Why does the Disco-Antistat Ultrasonic work at 46 kHz – and not at 80 or 120 kHz?

Why does the Disco-Antistat Ultrasonic work with 46 kHz – and not with 80 or 120 kHz?

A question we hear again and again.

---

If you have ever looked into ultrasonic record cleaning machines, you may have noticed:

Many manufacturers advertise with the highest possible ultrasonic frequencies.

60 kHz.

80 kHz.

120 kHz.

This suggests a hypothesis:

The higher the number, the better the cleaning result.

However, it's not that simple.

---

The most important number is not the frequency.

But the cleaning result.

When developing the Disco-Antistat Ultrasonic, we therefore asked ourselves a different question:

How do we clean records as thoroughly as possible – without unnecessarily stressing the vinyl?

The answer is not "higher frequency."

But:

The perfect interaction of all components.

---

Why exactly 46 kHz?

46 kHz has proven to be the optimal compromise in our development and long-term tests.

The ultrasonic waves reliably loosen dirt from the fine grooves.

At the same time, the system is gentle on materials and safe for vinyl.

But ultrasound is only one part of the whole for us.

---

Why does the ultrasound keep switching off?

We also get this question frequently.

The answer is simple:

Ultrasound generates heat.

If it were to run continuously, the cleaning fluid could continue to heat up.

However, vinyl reacts sensitively even at temperatures around 35 °C.

That's why the Disco-Antistat Ultrasonic deliberately operates in intermittent mode.

This keeps the temperature in the optimal range – and your records are cleaned particularly gently. This mode of operation is a conscious design decision and serves to protect the vinyl.

---

Why don't we only clean with ultrasound?

Because we are convinced that no single method alone delivers the best possible result.

That's why the Disco-Antistat Ultrasonic combines three cleaning technologies:

• 46-kHz ultrasound, which loosens even fine dirt from the grooves.

• Specially developed goat hair brushes, which gently support the cleaning process.

• An anti-static cleaning fluid, which removes dirt and simultaneously reduces static charge.

Our Conclusion

When it comes to ultrasonic record cleaning machines, it's not about the largest possible number.

What matters is how all components work together.

That's precisely why the Disco-Antistat Ultrasonic was developed as a coordinated overall system.

Because in the end, only one thing counts for us:

Clean records. Protected vinyl. More musical enjoyment.
