Parametric MID Frequence EQ

The circuit under discussion serves as a natural progression of the Mic-Line balance unit, but it can also be tailored to fit any other audio circuit. The circuit is essentially two units connected in series: A) A classic bass/Treble unit, and B) a parametric unit designed for mid frequencies. These units are designed with flexibility in mind, and can be operated either jointly or independently, with the necessary buffer unit, from preceding and following circuits.

The circuit's functionality is further enhanced by the inclusion of various resistors that regulate different frequencies. For instance, the R2 resistor is used to regulate the high frequencies at +/- 18 dB/octave at 20 KHZ. Similarly, the R5 resistor is in place to control the low frequencies at +/- 18 dB/octave at 20 KHZ.

For mid frequencies, the circuit relies on the R11 resistor, which regulates the mid frequencies at +/- 15 dB/octave. Furthermore, the R10 resistor is responsible for the center of mid frequencies, operating within the 200 HZ - 6 KHZ band.

It's important to note that the circuit's design allows for a wide range of frequency regulation, making it adaptable to various audio applications. This adaptability, combined with the ability to operate the units both jointly and independently, makes this circuit a versatile tool in the field of audio electronics.The circuit constitutes a natural extension of Mic-Line balance unit, but can be adapted to any other audio circuit. It is made up of two units in the series : A) A classic unit bass/ Treble and B) a parametric unit of mid frequencies.

Both units can also be used autonomously or each one separately, with the required buffer unit, from previous and subsequent circuits. With the R2 we requlate the High frequencies +/- 18 db/oct at 20 KHZ, with R5 the Low frequencies +/- 18bd/oct at 20 KHZ, with R11 the Mid freq.

+/- 15 db/oct and with R10 the center of mid freq. at 200 HZ - 6 KHZ band.
