AVT2671 B

The module uses the TDA7294 integrated circuit. He works in a typical factory configuration. The MUTE and STANDBY inputs allow you to easily eliminate all the noises and cracks that may appear when you turn the power on and off. The additional CTRL input allows the system to be connected to an external delayed start and quick shut down controller. An interesting solution is the use of forced cooling. A small computer heatsink was used, supplemented by a fan driven by a DC motor. The module enables the connection of two motors, their speed depends on the level of the output signal.

The device is especially recommended to constructors of audio equipment, electroacoustics and musicians

Selected power supply parameters:

• peak power output - <100 W
• useful power output - 80 W (for 4 ohms load, +/- 30 V supply)
• useful output power - 50 W (for 8 ohm load, +/- 30 V supply)
• harmonic distortion - <0.01%
• rate of signal rise on the output - type 10 V / us
• Supply voltage ± 10V ... ± 40V
• in the set a printed circuit board, a set of elements * and documentation

* The set contains one channel (one amplifier), without a power supply.
