The Furman TX-324 is a professional, rack-mountable stereo 2-way/3-way tunable crossover designed for bi-amplification or tri-amplification of loudspeaker systems in live sound and installed audio applications. It splits a full-range audio signal into separate frequency bands—typically low, mid, and high—which are then sent to dedicated power amplifiers driving specialized drivers (woofers, midranges, tweeters). This active crossover approach allows for precise control over the frequency response, phase alignment, and protection of each driver, resulting in improved system efficiency, headroom, and sound quality compared to passive crossovers built into speakers.

The TX-324 features continuously variable frequency controls for each crossover point, level adjustments for each output band, and selectable crossover slopes (e.g., 12 dB/octave or 24 dB/octave). It includes both XLR and 1/4" input and output connectors for versatile system integration. Housed in a single rack unit, this crossover is an essential tool for system technicians and audio engineers who need to optimize and tune the performance of multi-way speaker stacks in venues, touring rigs, or fixed installations, ensuring clear, powerful, and well-balanced sound reproduction.
