AVT2458 A

It is an amplifier with very good parameters for the subwoofer. The system is powered by battery voltage (14.4V). In addition to the power amplifier, it also contains an active filter with a switchable characteristic and differential input stages, allowing the use of a signal from any source. Thanks to the use of the TDA1562Q integrated amplifier, working in the H-class, it achieves an unbelievably high power output of 70W at a load of 4W at a 14.4V power supply.

Basic parameters:

• Working voltage of 8 ... 18V
• Permissible supply voltage 0 ... 30V (temporarily up to 45V)
• Quiescent current typ. 110mA, max 150mA
• Strengthening 26dB (20x)
• Maximum power (14.4V, 4Ω, THD? 10%) typ.70W
• Maximum power (14.4V, 4Ω, THD ± 0.5%) typ. 55W
• Maximum continuous output current 8A, peak 10A
• Nonlinear distortion (14.4V, 4Ω, 20W) typ. 0.06%
• Upper limit frequency> 20kHz
• a printed circuit board and documentation in the set
  A version with a set of components for self-assembly is available
