AVT1249 B Car superwave

The device is a complete four-channel power amplifier adapted to work in a car. The putty construction was based on the TDA8571 integrated circuit. It contains all the elements necessary to work the tip, so you can simplify the scheme of the device as much as possible. Additional elements are attached to the MODE cube input. Thanks to them, it is possible to smoothly switch the output signal. This eliminates unpleasant noises and knocks when the amplifier is powered up. Shorting the MODE terminal to ground allows the system to be in standby mode and reduced power consumption. All speakers work in a bridge connection. The "cube" manufacturer implemented a number of protections in it: before shorting the outputs, before exceeding the maximum temperature, etc. The system was adapted for additional control, improving cooling by a fan. The device is especially recommended for car sound systems. Selected parameters of the amplifier:

• four-channel system
• output power - approx. 25 W / channel (14.4 V, 4 ohms)
• built-in protection circuits
• mute / standby system
• output for controlling the fan
• three additional plates to make the kit
• power supply - 14.4 V
• in the set a printed circuit board, a set of elements and documentation

Semiconductors: TDA8571J, BD136, 1N4148, 1N4001 Power supply: 12 ... 14,5V Tile dimensions: 48 x 96 mm
