Octave Filter 3-P: Advanced EMI Filter for Superior Audio Clarity

The Octave Filter 3-P is a passive electromagnetic interference (EMI) filter engineered to enhance audio system performance by eliminating conducted EMI in analog signal paths. Addressing interference directly within the signal cabling ensures cleaner, more precise audio reproduction.

Key Features

• Effective EMI Suppression: Filter 3-P significantly reduces common-mode noise, attenuating approximately -80 dB at 1 kHz, corresponding to a reduction factor of 10,000.
• Broad Frequency Range: Operates effectively across a frequency range of 10 Hz to 150 kHz, ensuring comprehensive filtering without compromising audio signal integrity.
• Versatile Connectivity: Available in two versions, featuring single-ended RCA or balanced XLR connections, allowing seamless integration with various audio components.
• Innovative Filter Technology: Utilizes a specialized broadband interference suppression transformer to block interference from bass to the highest audio frequencies without impacting the original signal.
• Ground Lift Switch: Equipped with a ground lift switch to prevent ground loops, enhancing system compatibility and reducing potential hum.
• Design and Build: The Filter 3-P is housed in a robust metal case made from solid, magnetically optimized steel and cast in resin for durability and adequate shielding. Its compact dimensions (70 x 75 x 186 mm) and weight (3.6 kg) make it a practical addition to any audio setup.

Integrating the Octave Filter 3-P into your audio system can significantly reduce EMI, enhancing clarity and detail in your audio playback.
