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.

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.
