DETAILED DESCRIPTION

[0013] As shown in the FIGURE, the “ELECTRONIC CIRCUIT FOR AMPLIFIERS AND SOUND DEVICES FOR THE TRANSFER OF ELECTRIC POWER BETWEEN CHANNELS” under this patent application consists of an electronic circuit (1) dedicated to transferring the output power to one of the channels/speakers in a free and individual way, from one side to the other, being able to equalize and amplify each channel (speaker), permitting a power division not necessarily equal for to said channels. The electronic circuit (1) comprises a microprocessor (2) connected to a DSP (3) (Digital Signal Processor) to control the sending of maximum and minimum electrical power to each channel/speaker.

[0014] More specifically, the electronic circuit (1) acts in the audio input (4) interconnected to a preamplifier (5), which communicates with the DSP (3), whose function is to process and optimize the signal and perform the equalization and amplification of each channel (speaker), while the DSP (3) is interconnected to an AF power amplifier (6), which is connected to a switched power supply (7) an SMPS DC-DC, which regulates and adjusts the desired voltage in the electronic circuit (1). It is worth pointing out that the switched power supply (7) or SMPS DC-DC communicates all the time with the preamp (5) and therefore with the DSP (3).

[0015] In time, the AF power amplifier (6) is interconnected to an audio frequency amplifier (8) AF, whose function is to increase the amplitude of the audio frequency signal. In this way, the microprocessor (2)connected to the DSP (3) processes and stores the information of the electronic circuit (1), while the DSP (3)is connected to an auxiliary audio output (10). Nevertheless, the electronic circuit (1) can be controlled by a digital panel/display (11) and/or dedicated application (12), so that the user can control the power sent to each channel individually, being able to transfer the excess power on one channel to another channel of their choice.

[0016] Therefore, the digital panel/display (11) can be installed on the amplifier/sound system itself, as well as the dedicated application (12), can provide individual control parameters to allow the user to control the sending of electrical power to one channel/speaker of the amplifier/sound system by the DSP (3).

[0017] That is, the electronic circuit (1) works as a kind of electrical power equalizer, distributing it between the channels/speakers of the sound system freely and as defined by the user, allowing from the normal balance of the power of each channel, up to the use of the power initially intended to a certain channel to feed another channel, which, therefore, has its power increased (power transfer). The electronic circuit (1) allows for increasing and decreasing the power of each channel individually, as well as taking power from one or more channels to use in another.

[0018] In this way, an amplifier with four channels, for example, could have one of its channels fed with part of the electrical power that would be sent to the other three channels, as well as it could have its electrical power reduced or cut off, without changing the other channels, as well as performing the division and power, not necessarily equal to said channels.

[0019] Therefore, unlike circuits already available on the market, the electronic circuit (1) has full control over the independent maximum power in each of the outputs, and can also be adjusted by the user in addition to the ability of transferring power from a channel to the other.
