PFMOD HP-1 (High Pass)
Product Details
The Harrison Laboratories HP-1 (High Pass) is part of the PFMOD series, is a professional-grade, passive, adjustable high-pass crossover. It functions as a "line-level bass blocker," designed to filter out low frequencies before they reach your amplifier and speakers . This prevents distortion and protects smaller drivers—like satellite speakers, mid-range drivers, or tweeters—from bass overload .
Core Functionality & Technical Design
The HP-1 is a passive device, meaning it requires no external power and introduces no electronic noise or distortion . It is designed for high-end signal transparency using 24kt gold-plated machined brass construction .
- Adjustable Frequency Selection: Unlike the standard fixed FMODs, the HP-1 features internal factory-set jumpers that allow the user to select between multiple discrete high-pass frequencies, typically including 50, 70, 100, and 150 Hz .
- 12 dB/Octave Slope: It utilizes a standard 12 dB per octave slope . This provides a musical transition that rolls off low frequencies while maintaining clarity in the mid-range .
- Active Crossover Simulator: It is marketed as an active crossover simulator because it offers precise frequency control comparable to powered units without the complexity or cost.
