What Is Inside the VeraTone Desk-Box

Frequency Generation

A crystal oscillator and precision DAC produce a sine wave across a range of 0.01 Hz to 200 kHz. You can select the Schumann value of 7.83 Hz or another frequency in that range.

Fanless Housing

The acrylic desk-box has no fan inside. It measures 4 by 4 inches, so it fits on a nightstand, a desk, or a shelf near where you plan to use it.

VeraTone

Audio Output

A 3.5 mm audio output cable comes in the package for connecting to audio gear. The Speaker bundle variant also includes an external speaker that you can use with that output.

Knob and OLED Controls

You turn the knob and watch the OLED display show the frequency value. There is no app, no Bluetooth pairing, and no software to install. The knob and display are the whole interface.

Frequently Asked Questions

Plug the USB-C cable into a phone charger or a power bank, then roll the knob until the OLED shows the frequency you want. No app, laptop, or software is involved in setup.

No. The acrylic desk-box is fanless, so there is no fan inside the housing. You can leave it powered on a nightstand or desk for as long as you want to use it.

A crystal oscillator and a precision DAC generate a sine wave. The output covers the 0.01 Hz to 200 kHz range, and you select the value with the knob while reading it on the OLED.

No. VeraTone is a standalone desk-box with no app and no wireless pairing. The knob and the OLED display are the entire interface, so you set everything on the unit itself.

It uses a USB-C port. You can connect it to a standard 5V phone charger or a 5V power bank with the 3 ft USB-C cable that comes in the package.

Use the 3.5 mm audio output cable from the package. An external speaker is included only in the Speaker bundle variant, so check which version you selected.

The desk-box measures 4 by 4 inches, so it fits on a nightstand or a desk, or it can sit beside a yoga mat. Any spot within reach of a USB-C power source works.

Wipe the shell with a dry microfiber cloth about every couple of weeks. Unplug the USB-C cable first, and avoid pressing on the knob or the OLED display while you clean.

VeraTone works as an adjustable frequency generator across 0.01 Hz to 200 kHz, so a 528 hz frequency generator setting is available along with 7.83 Hz. A crystal oscillator produces the sine wave output.

The 528 hz frequency generator ships as a 4-by-4-inch fanless acrylic desk box with a 3 ft USB-C cable, a 3.5 mm audio output cable, and a quick-start card listing 12 frequencies.

VeraTone: A 528 Hz Frequency Generator for Desk Use

VeraTone is a compact 528 hz frequency generator in a 4-by-4-inch acrylic desk box. A knob and OLED display set the output across a range of 0.01 Hz to 200 kHz.

Because the number is user-set, it also works as an adjustable frequency generator and a 7.83 hz frequency generator for the Schumann value. Those looking for a solfeggio frequencies generator can set the tone they want directly, with no app or pairing.

Inside, a crystal oscillator produces the sine wave, and the fanless shell is acrylic. Power comes from the USB-C port using any standard 5V phone charger or power bank. It sits on a nightstand, a desk, or beside a yoga mat. The package for this 528 hz frequency generator includes:

  • 3 ft USB-C cable
  • 3.5 mm audio output cable
  • Quick-start card listing 12 common frequencies
