Frequently Asked Questions

Q: What type of crossover filter does this 3-way frequency board use?

A: This crossover board uses a Linkwitz-Riley filter design with a -24 dB/Oct slope attenuation, which ensures smooth, accurate frequency separation between the bass, midrange, and treble bands with no unwanted peaks or phase issues.

Q: What are the default crossover frequency points on this board?

A: The default crossover points are 310 Hz and 3.1 kHz. This divides the audio spectrum into: Bass (20–310 Hz), Midrange (310 Hz–3.1 kHz), and Treble (3.1–20 kHz). The crossover points are replaceable/adjustable to suit your specific speaker system.

Q: What power supply does this crossover board require?

A: The board requires a dual (bipolar) AC transformer power supply in the range of ±14V to ±19V. It is not powered via USB or a standard DC adapter — a proper bipolar transformer supply is needed for correct operation.

Q: Is this board suitable for beginners in DIY audio?

A: This board is best suited for intermediate to advanced DIY audio enthusiasts who are familiar with multi-amplifier speaker setups and basic electronics wiring. Its independent channel adjustments and gold-plated RCA connectors make integration straightforward for those experienced with audio builds.
