AVT2783 A

The presented control indicator is distinguished not so much by the electronic system as by the type of enclosure and LEDs used. The whole should be placed in an impressively shiny metal furniture tube. In combination with super-bright blue LEDs, this guarantees an amazing effect, the larger the darker the room where the device is located. In terms of electronics, the system is uncomplicated because it is based on the popular LM3916 chip. The indicator can work in point mode (one diode always lights up) and the ruler mode (one to ten LEDs are lit at the same time).

The device is especially recommended as an element of power amplifier, in audio and video devices

Selected parameters of the indicator:

• signal level imaging - blue LEDs
• number of diodes - 10
• two work modes - point and ruler
• possibility of connection to the stereo track (both channels simultaneously)
• input voltage (for elements from the diagram) - 0-1.2 V (direct voltage)
• power supply - 6-15 V (max 25 V)
• printed circuit board and documentation included
  A version with a set of components for self-assembly is available
