AVT2499 B

Four-channel audio amplifier with a maximum output power of 160 W (4x40 W). The set uses a TDA8571 integrated circuit from Philips. This block has a number of circuits protecting the amplifier from damage. These are circuits protecting against the effects of short circuit, overheating, electric charges and reverse connection of power supply. In addition, diagnostic circuits were made in the structure - the appearance of a low state at the appropriate end indicates the existence of a problem or a temporary overdrive.
The MODE input allows you to enter the system into STANDBY mode. Amplifier current consumption then drops to the level (type) 1 uA.
The amplifier is mounted on a small printed circuit board. A small number of elements makes it a convenient module for complex audio devices.

The device is especially recommended for all building audio equipment, both stationary and for motor vehicles

Selected parameters of the amplifier:
