A simple system that allows you to convert a stereo amplifier into a device with four times higher peak power (doubled continuous power). This is the so-called inverter - its both outputs provide signals of equal amplitudes, but opposite in phase. After connecting the finished power amplifiers, also on their outputs there will be an opposite signal in phase, with a large amplitude. In this way, the bridge amplifier type BTL (Bridge Tied Load) will be created. This allows a significant increase in the output power.
ATTENTION!!! The doubler should not be used for car amplifiers that are originally designed like bridge systems.
The device is especially recommended for converting several years old stereo amplifiers or radios equipped with them
Selected parameters:
- two outputs delivering a signal with the same amplitude but the opposite phase
- 1V / V gain (in both tracks)
- maximum output output value 2Vpp (0.7Vsk) for 6V power supply
- one power supply
- possibility of mounting potentiometers for precise reinforcement of both channels
- power supply - 6-15 Vdc
- a printed circuit board (integrated circuit version), a set of elements and documentation
- Detailed description in EdW 3/07
