4pcs YLY-2088 2 Way Crossover  Module 400W Audio Speaker Frequency Divider Adjustable Full Range Treble Bass Welding Free       	Feature:       	1. Multi-Purpose Flexibility: This crossover filter is highly versatile and fully adjustable, requiring no soldering for use. It's suitable for a range of applications, including high-frequency and low-frequency two-way speakers, 2.1-channel high-frequency satellite boxes, car full-range speakers, and even individual high or low-frequency setups. It accommodates speakers with 4-16 ohm impedance and supports up to 400W of power.  2.  Components: Equipped with pure copper jumpers featuring four selectable positions (A, B, C, D) and four plug caps, this speaker frequency divider uses top-quality copper wire inductors, capacitors, and sockets, along with a fiberglass circuit board. It offers adjustable high-frequency settings (weak, medium, strong) and low-frequency settings (full sound, low sound, strong bass, medium sound).  3. Expert Soldering Craftsmanship: Constructed with professional point-soldering technology, this audio speaker frequency divider features uniformly sized and fully filled solder joints that are polished to a bright shine, ensuring reliability and performance.  4. Superior Copper Inductors: Utilizing 0.8mm oxygen-free copper wire for winding pure copper inductors, this 2 way crossover  module includes a 100uF large-capacity capacitor. It features a connection socket for easy wiring with a small screwdriver and supports multiple 6dB circuit combinations to achieve a variety of crossover frequencies.  5. Thoughtful Design: The HiFi speaker modification upgrade board boasts a well-thought-out design, an elegant appearance, and excellent sound quality. Users can easily adjust the sound to suit their personal preferences, enhancing the overall audio experience.       Specification:  Origin: Mainland China  Model: YLY-2088  Frequency point: not located, determined by debugging  Power: 400W  Impedance: 4-16 ohms  Material: The inductor is wound with oxygen free copper, with a pure copper wire diameter of 08. Super large capacity capacitor, reasonable design, exquisite appearance, and comprehensive control of sound quality.  Size: 7x5x2.5cm/2.75x1.96x0.98inch  Weight: 75g  Instructions for use:  High and low split frequency wiring:  Input: Connect to the power amplifier or rear junction box;  TREBLE: Connected to a tweeter;  BASS: Connected to the bass speaker.  Wiring base twisting operation:  Use a small slotted screwdriver to loosen in a counterclockwise direction, slide the compression plate down, peel and insert the wire, and tighten clockwise.  Full frequency coaxial connection method:  Connect the speaker to the BASS/bass position, and then find a small wire to connect from the positive pole of the bass to the positive pole of the tweeter.  Warm Tips:  The manual tightening force will be stronger than the fixed feet of the wiring base to avoid deformation. When tightening, use your fingers to pinch the wiring base to tighten it. In case the compression plate cannot be tightened due to being too loose, turn the frequency divider upside down, screw in the compression plate, and then return to the wiring.
