Description

Philips 4 2 - 2 . . TDA7379 , . Thanks to the wide voltage range and to the high out current capability it is able to supply the high- est power into both 4 and 8 loads even in pres- ence of poor supply regulation, with high Supply. Voltage Rejection. The built in muting function with turn on delay sim- plifies the remote operation avoiding switching on -. TDA7379 amplifier chips provide a good solid foundation for quality sound and all the power needed to drive the subwoofer and satellites. SPD technology. Philips Sound Purification Duct (SPD) bass port technology delivers the deep, pure tones of the original bass sound. Using an SPD foam material to process the inner channels to give you the better sound quality you need. Philips uses 4 integrated amplifier chips to drive the 2 channels of two satellite speakers and 2 channels of the subwoofer. These TDA7379 amplifier chips provide a good solid foundation for quality sound and all the power needed to drive the subwoofer and satellites. Feb 27, 2008 The TDA8948J contains a unique protection circuit that is solely based on multiple temperature measurements inside the chip. This gives maximum output power for all supply voltages and load conditions with no unnecessary audio holes. Almost any supply voltage and load impedance combination can
