Features: Adopting precise circuit design to achieve precise separation of high and low frequency signals. 400W power carrying capacity, high temperature resistant magnetic cored inductors and large capacity capacitor, with strong and stable performances. Multi segment parameter adjustable design, which can be flexibly adjusted according to preferences and loudspeaker characteristics. 2.0mm thick aluminum heat dissipation shell with epoxy resin sealing process effectively suppresses mechanical resonance; Gold plated terminals blocks ensuring stability. Built in transiently varistor and temperature fuses effectively resist overload shock. Adapt to 4-8Ω impedance units, reserved intermediate frequency expansion interfaces, support later upgrades to three-way systems, with strong expandability. Specifications: Model: WEAH-247 Frequency division: 1 high and 1 low (two divisions) Size: 132x98x38mm Net weight: about 251g/piece Withstand power: 400W Applicable impedance: 4~8Ω Applicable loudspeakers: stage/KTV loudspeaker modification and upgraded Package Includes: 1Pc WEAH-247 400W Power Adjustable Frequency Divider note: Due to problem of lighting effect there might be tolerances in product, please understand. Please allow 0-2mm error due to manual measurement.
