Indian Xtreme Audio Low Pass Filter LPF4

The Indian Xtreme Audio LPF4 is a high-performance low-pass filter designed to offer precise audio control and superior sound quality. Featuring Vishay components and Texas Instruments op-amps, this filter ensures minimal distortion and exceptional signal clarity. With 1% metal film resistors (MFR), the LPF4 is ideal for professional audio systems, home theaters, and audiophile setups.

Special Features:

• Phase, Frequency, and Volume Control: Full customization of low-end frequencies to meet your specific needs.
• Expandable Potentiometers: Smooth, durable potentiometers for easy, fine-tuned adjustments.
• Line Out Functionality: Provides a clean, noise-free output for easy integration with external audio systems.

Operating Details:

• Working Voltage: Comes with an inbuilt rectified power supply, allowing operation directly from a 15-0-15 AC transformer with 500 mA current capacity—no need for external adapters.
• Frequency Response: Covers a broad range from 20Hz to 150Hz, perfect for eliminating high-frequency noise while preserving deep, rich bass.
• 4th Order 24dB Low Pass Filter: With a 24dB per octave roll-off, this filter offers a steep and precise cutoff, ensuring clean, accurate low-end performance.

What Are Filter Orders?

In audio filters, orders indicate the rate at which the filter attenuates signals beyond the cutoff frequency. A 4th-order filter reduces the signal by 24dB per octave, offering a sharper, more effective cutoff compared to lower-order filters. Higher-order filters provide greater isolation of the desired frequency range, ideal for high-fidelity audio control.

Control Descriptions:

• Frequency Control: Adjusts the cutoff frequency of the low-pass filter, allowing you to fine-tune the range of low-end frequencies that pass through. The LPF4 gives you precise control over which frequencies are filtered, ranging from 20Hz to 150Hz.
• Phase Control: Allows you to invert or adjust the phase of the audio signal, helping to align the phase of your subwoofer or speakers with the rest of your system. This can be crucial for maintaining proper sound alignment and preventing phase cancellation, ensuring better bass response.
• Volume Control: Adjusts the output volume level of the filtered signal, allowing you to set the desired loudness for your subwoofer or low-frequency device. This control ensures smooth integration with the rest of your audio setup, maintaining consistent sound levels.

Compatibility:

• Best for Subwoofers: The LPF4 is specifically designed to enhance the performance of subwoofers, ensuring deep, controlled bass while removing high-frequency noise that can interfere with subwoofer output.
• Pro Audio Systems: Perfect for use in studio setups, live sound systems, and mixing applications, where precision low-frequency control is critical for achieving professional-grade audio.

The Indian Xtreme Audio LPF4 is an essential tool for anyone seeking to fine-tune their audio system’s bass response. Whether you’re working with subwoofers, pro audio gear, or home theater systems, this low-pass filter delivers superior sound control with precise frequency, phase, and volume adjustments.
