The Bio Tuner

The Bio Tuner is an electronic relaxation system based on the research that introduced the BT5 in 1983.

The BT7 Bio Tuner outputs a modified rectilinear waveform with hundreds of harmonic frequencies in each pulse. Six different user-selectable Modes settings are available.

The BT7 offers the following advanced features:

• Quartz crystal frequency control.
• Advanced microcomputer operation. The proprietary software routine is written by SOTA to ensure consistent and reliable output.
• Built-in 20 minute digital timer.
• Custom Headset
• Very simple intuitive operation.
• A push-button switch to easily change the output to each of the 6 different modes. (Mode 1 is the same as the BT5pro.)
• Two of the modes contain the 7.83 Hz Schumann (Earth) frequency.
• Headset and Output Signal Electrical Circuit Verification Indicator
• Low battery warning light.
• CE Certified

The BT7 is manufactured to the highest standards for the utmost quality and reliable service. Check out SOTA Insturments Canadian website for more information.

What is "The Bio Tuner"?

The Bio Tuner is an electronic relaxation system. Micro-current energy pulses appear to have a profound balancing effect on the individual and tend to produce a state of over-all relaxation and well being. The Bio Tuner outputs a modified rectilinear waveform with hundreds of harmonic frequencies in each pulse. 

Unit is covered by a 3 year warranty on internal mounted components.

The BT7 is very lightweight (a few ounces) and operates from a standard 9-Volt Alkaline battery.

The BT7 is housed in an attractive custom plastic enclosure, with a built-in compartment for the 9 Volt battery. A slide-off lid allows you to change the battery easily. A Thumbwheel Switch Control Knob turns The BT7 on and off and varies the intensity of the output. The Green LED light indicates the output Mode. When the Headset is functioning correctly, the Yellow light will come ON. The Red LED light is a low battery warning light. When this Red light goes on, it's time to get a fresh battery.

The Headset simply plugs into the output jack on the end panel of the BT7.

Unique Features:

• Very simple intuitive operation.
• A push-button switch to easily change the output to each of the 6 different modes. (Mode 1 is the same as the BT5pro.)
• Two of the modes contain the 7.83 Hz Schumann (Earth) frequency.
• Light to indicate each of the different modes.
• Light to indicate Headset is functioning correctly.
• Low battery warning light.
• The output wave forms of the BT7 are identical to the original BT6 settings.
• Newly-designed Headset. (Can also be used with the BT6pro, BT6, BT5pro and BT5)
• The new Headset has been carefully designed for high reliability, user comfort and ease of replacement.
• Compact and lightweight size.

BT7

• Maximum <1.5mA Peak ~40 Volts Peak-Peak into typical 4k ohm load. Minimum <~10 microamperes, 10 Volt Peak-Peak at lowest setting. Output impedance ~20k ohm.
• Modified rectilinear wave with rapid rise time (under 1uS). There are over 500 harmonic frequencies delivered in each pulse as observed on a frequency domain (not time domain) spectrum analyzer.
• Base waveform (Mode 1) 1,000 Hz Square wave (+/- 1%) pulse-modulated by 111.11 Hz (+/- 1%) Square wave. Waveforms are Microchip Quartz Crystal-Controlled for precise frequency output. There are 6 user-selectable output Modes.
• 9-Volt DC Alkaline Battery operation, useful to end voltage ~5.2 Volts. Battery drain: minimum ~9mA @ 9 Volts to maximum of 30mA with output fully loaded.
• Auto-shutoff time of 20 minutes. Controlled digitally.
• Pulses are Bi-Phasic (AC) with no DC or offset bias. Output is transformer coupled so that no direct current can appear at electrodes. The algebraic sum of positive and negative-going pulses is zero. This obviates any possibility of electrolysis, ion migration, or polarization.
• Low battery indicator. Low battery circuitry illuminates Red LED light when battery voltage is low.
