Audyn Q4/40/400 | 40 µF | 5% | 400 V

The Audyn Q4/40/400 is a premium 40 µF foil capacitor engineered for audiophiles and professionals who demand uncompromising signal integrity. As part of the renowned Q4 series, this component delivers exceptional performance in high-fidelity loudspeaker crossovers, tube amplifier circuits, and precision audio restoration projects. Its robust construction ensures reliable operation in both passive and active filtering applications, making it an ideal choice for upgrading vintage equipment or building bespoke sound systems.

Technically, this capacitor offers a tight ±5% tolerance, critical for maintaining accurate crossover frequencies and phase coherence in multi-driver speaker designs. With a 400 V DC rating, it comfortably handles high-voltage peaks in valve amplifiers and power supply decoupling stages. The axial lead style simplifies installation on point-to-point wiring or printed circuit boards, while the compact 44 x 45 mm dimensions allow integration into space-constrained chassis. The foil dielectric construction minimises dielectric absorption and distortion, preserving the natural timbre of music across the entire frequency range.

Whether you are refining a studio monitor crossover or restoring a classic amplifier, the Audyn Q4/40/400 provides the precision and reliability required for critical audio paths. Its meticulous manufacturing ensures consistent performance, delivering transparent sound reproduction that reveals every nuance of your recordings.
