The choice of the hi-end-amplifier TDA7293 Power amplifier TDA7293 from the company ST Microelectronics are the most widespread power amplifiers available in our market. Even if his own conception is integrated, contains a number of protections, which greatly contribute to extending the life of the entire amplifier.
The main reason for the choice of TDA7293 is the possibility of the involvement of the amplifiers in the mode Master / Slave (main / subordinate), when the main amplifier at the moment of inability to deliver power output to load activates the subordinate amplifier and the missing performance of the ship. This way you can achieve this with the help of two TDA 7293 power up to 150 W. Among the other advantages of options TDA7293 is a possibility to use the MUTE function (mute), when the output signal will be suppressed.
Circuit LM1036 contains the proceedings of the frequency characteristics for the two inputs and ranks the stereo monolithic correction amplifiers. While the involvement of recommended components in the vicinity of the integrated circuit, the circuit is fully functional and allows both management the total amplification, and own amplify the bass and treble. From this it follows that it is a dual-band the correction amplifier.
Bridge Amplifier TDA7293 Circuit
The advantage of the correction amplifier LM1036 is that for the management of individual parameters (volume, depth, height, balance) is not needed double potentiometers, but only simple. This feature greatly facilitates the search for errors when, for example, a depth on one channel were in order and on the second channel were muted.

TPA3106D1 Class-D Power Amplifier Projects Ecc83 JCM800 Preamp
The involvement of the preamplifier This is a long-established involvement with tubes type ecc83. This involvement is used by legendary guitar amps Marshall JCM 800
After studying the issue, I decided for the implementation of digital audio amplifier using the circuit TPA3106 D1 of the firm Texas Instruments. The picture sleeve is located on the fig. 7, In came into consideration also the circuits of the company Maxim, however, the parameters of the circuits they were not so interesting. In the selection

Die Wahl der hi-end-Verstärker TDA7293-Endstufe TDA7293 von der Firma ST Microelectronics sind die am meisten verbreiteten Endstufen finden Sie in unserem Markt. Auch wenn er seine eigene Konzeption integriert ist, enthält eine Reihe von Schutzmaßnahmen, die viel dazu beitragen, verlängern die Lebensdauer des gesamten Verstärkers.
