Notes:
Our electronic three-divider parts need to be welded by yourself, enthusiasts should do what they can, do not buy kits without foundation, kit parts are tested and shipped, and free maintenance is not provided. Please understand that electronic component identification tutorials are not provided. After welding, it is exactly the same as the picture below.

Performance parameters:
1 Filter type: subtractive divider
2. Crossover point: Crossover point 500HZ, 5kHZ (i.e. 20HZ-500HZ for bass output 500HZ-5KHZ for midrange output 5KHZ-20KHZ for treble output)
3, attenuation slope: -24dB/0ct
4, plate structure: 3 channel output, treble, bass, mid
5. Operational amplifier chip: NE5532P (other operational amplifiers can also be replaced according to customer needs, such as: OPA2604AP OP275G TL072, etc.)
6, PCB size: 98 * 84 mm
7, DC positive and negative double 9-15V
Electronic frequency division advantages:
1.Electronic frequency division eliminates the insertion loss of power division.
2.Electronic crossover improves the damping coefficient of the speaker system.
3, the phase characteristics of the electronic frequency division are better.
4. The frequency division point and frequency division characteristics of electronic frequency division are easier to control.

Frequency division formula

The 10k resistor in the picture above cannot be changed

The R calculated by the calculation software is too large, such as C=1nF, f=5kHz; according to the formula f=0.707/(2X314Rc) the data is very accurate) R=22k. So the following number

According to (Increase C by 10 times, R remains unchanged, f becomes 1/10 of the original) For reference only

When C=1nF, f=5kHz, R=225k (the accurate data should be 22k)

C=1nF, f=4.7kHz f, R=24K.

C=1nF, f=4.4kHz #f, R=256k.

C=1. nF, f=4.1kHz f, R=183k

C=1.nF, f=3.8kHz Hf, R=19.7k.

When C=1.5nF, f=3.5kH, R=214kC=1.5nF

When f=35kHz, R=21.4k

When C=15nF,=32kHz, R=235k (I used C=15nF, R=22k, use the formula f=3333Hz, use soft

Piece f=3410Hz)

C=2.2nF, f=3kHz Hf, R=17k

C=2.2nF, f=2.8kHz Hf, R=183k

C=2.2nF, f=2.5kHz f, R=20.5k.

C=2.2nF, f=2.2KHz Hf, R=233k

C=2.7nF, f=2.2kHz Bf, R=19k.

C=2.7nF, f=2KHz Hf, R=20.8k.

C=3.3nF, f=1.8kHz Hf, R=19k.

C=3.3nF, f=1.5kHz f, R=22.7k

When C=47nF=1.3kH, R=184k

C=4.7

At 1kHz, R=24k

C=6.8nF, f=1kHz f, R=16.6k.

When C=68nF, f=900Hz, R=18.4k

C=6.8nF, f=800Hz f, R=20.7k

C=6.8nF, f=700kHz Hf, R=23.6K.

When C=10nF, f=700Hz, R=16.1k

C=10nF, f=600Hz Hf, R=18.8k.

When C=10nF, f=500Hz, R=225k (the accurate data should be 22k)

The good effect is related to the relative accuracy of the resistance and capacitance data, especially the resistance needs to be relatively consistent in size. Choose the largest and smallest capacitance in the parallel connection place, so that the error will be smaller.
