The ALTO X-23SW crossover is designed to deliver precise system control. Linkwitz / Riley 24dB/Octave filters between frequency bands and a high slew / rate design ensure precise crossover division. Shielded internal power supply and servo balanced inputs and outputs deliver truly transparent crossover operation, offering over 115dB dynamic range. User switchable constant directivity horn equalization circuit boosts high frequency output by 3dB at 3.5kHz, then +6dB per octave to 22.5kHz to aid horn drivers in large PA setups. Individual mute and phase inversion switches on each band allow Alto analog crossovers maximum flexibility and system control in any live PA or DJ setup.
