Introduction to the three-way frequency divider circuit: This frequency divider is set to a stereo 6-channel output structure, inputs stereo left and right channel signals, and outputs 6-channel signals, which are divided into left treble, left bass and right treble, right bass, left mid-range, and right mid-range, which can directly drive the 6-channel power amplifier circuit. of this frequency divider: Excellent frequency divider circuitNo peaks or valleys in the frequency dividerEasy to set the frequency divider point adjustment of 6-channel outputFever-grade design and productionPerfect reproduction of the original sound tone 1. Wave generator type: Limkcwitz-Rilev filter 2. Crossover point: 310HZ3.1KHZ (. 20HZ-310HZ for bass output, 310-3.1KHZ for midrange output, 3100-20KHZ for treble output) Crossover point can be customized to other frequencies (free customization. The crossover points for different speakers are different. You can give me the crossover point and I help you calculate the circuit parameters before selling it 3. Attenuation rate: -24dB/Oct 4. Board structure: 6-channel output, treble, bass, midrange 5. Op amp chip: double-precision NE5532 (of course, other op amps can be replaced according to customer needs, such as: OPA2604AUOP275GTL072, etc.) 6. Board dimensions: 173 x 79mm 7. AC former power supply range dual 14 to dual 19V 8. Connectors: audio input/frequency division output... 2-link gold-plated lotus socket x 4 Color: Green Material: ABS Package Contents: 1 * Divider Board Only the above package content, other products are not included.
