3 Way Active Crossover Filter Board – PCB only

3-Way Active Crossover Filter PCB Board (Linkwitz-Riley, Bare PCB)

This PCB is designed for building a 3-way active crossover using Linkwitz-Riley filter topology for audio signal separation into low, mid, and high frequency bands.

Working Voltage:

• Dual supply: ±12 V DC (regulated supply required)

Signal Processing:

• Three separate outputs: Low, Mid, and High frequency bands
• Signal gain: up to 20 dB (depends on component values)
• RF input filter for reduction of unwanted noise

Op-Amp Compatibility:

• Supports NE5532, TL072, JRC4558, TL084, TL074, LM324

Protection Features:

• Reverse polarity protection using diodes

Connectors:

• 2.54 mm JST / Relimate connectors for input, output, and power connections

Board Specifications:

• PCB dimensions: 103 mm × 53 mm
• Compact layout for integration

Construction:

• Bare PCB (components not included)
• Designed for through-hole components

Configuration:

• Requires regulated ±12 V DC power supply
• Crossover frequencies depend on component selection and assembly

Intended Use:

• Active speaker systems with separate low, mid, and high frequency drivers
• Multi-way audio amplifier setups
• DIY audio crossover and signal processing projects
