C-500/750

The Ahuja C‑500/750 Networks Board is a high‑quality two‑way passive crossover network engineered for use in professional PA speaker builds and sound reinforcement systems. It effectively directs low frequencies to the woofer and high frequencies to the HF driver, ensuring each driver receives the appropriate range for clear, distortion‑free sound reproduction. This model is rated for 500 W RMS power handling, making it suitable for medium‑power speaker cabinets.

Built with air‑core coils for low resistance and high‑quality metallised polyester capacitors, the crossover offers robust performance and durability. It also includes a PTC (positive temperature coefficient) resistor in the high‑pass section to provide overload protection for the high‑frequency driver, helping it withstand transient peaks without damage.

Key Features:

• Power Handling: 500 W RMS – suitable for mid‑range PA systems.

• Crossover Type: Two‑way passive network for balanced LF/HF distribution.

• Crossover Frequency: ~1.2 kHz – optimized for typical woofer and HF driver pairing.

• Nominal Impedance: 8 Ω – compatible with standard speaker drivers.

• Filter Slopes:

  • Low‑pass: ~12 dB/octave for woofer.

  • High‑pass: ~18 dB/octave with PTC protection for HF driver.

• Driver Protection: Built‑in PTC resistor in the high‑pass section for tweeter safety.

• Build: Heavy‑duty passive components for reliable performance.

• Dimensions & Weight: ~W 225 × H 35 × D 169 mm — ~1.2 kg.
