The Furman P-2400 IT: Professional AC Ground Loop Isolation & Balanced Power in One
AC Ground Loop Hum: Why Standard Solutions Fail
That low 60 Hz hum in your vocal recording? It's AC ground loop hum—and it's not your microphone's fault. Cheap surge protectors ignore AC ground loops entirely. Passive AC ground loop isolators address only cable-level hum, not the root problem.
How the P-2400 IT Solves AC Ground Loops
The P-2400 IT is a symmetrically balanced power conditioner that eliminates AC ground loop hum without rewiring. It provides 100% isolation from the building's electrical ground, breaking the AC ground loop at the source. The Ground Lift Switch allows you to float the output ground for additional AC ground loop hum elimination. Install once, adjust the switch, and AC ground loop hum is gone.
Key Features
- Ground Lift Switch — Floats the output ground to break AC ground loops and eliminate residual hum.
- Symmetrically Balanced Power Distribution — Provides 100% isolation from line, neutral, and ground, eliminating AC ground loop pathways.
- 80 dB Common-Mode Noise Reduction (20 Hz–20 kHz) — Designed for noise-critical environments like mastering studios and broadcast facilities where AC ground loop hum must be eliminated.
- 10 Ultra-Low-Resistance Hubbell Outlets — Heavy-duty, GFCI-protected. 20 amp / 2,400 watt capacity.
- SMP Multi-Stage Protection + EVS — Clamps voltage spikes at 188V (vs. 300V+ for standard surge protectors). EVS instantly shuts down the unit if voltage exceeds 140V, protecting against dangerous wiring faults that may worsen AC ground loop hum issues.
- Non-Sacrificial Surge Protection — Doesn't degrade with use. Provides ongoing protection for the life of the unit.
Where AC Ground Loop Hum Becomes Critical
- Recording Studios — Mastering with audio rely on the P-2400 IT to eliminate AC ground loop hum in noise-free recordings. The 80 dB noise reduction preserves low-level detail in 24-bit recordings by eliminating AC ground loop contamination.
- Broadcast & Video — AC ground loop hum manifests as visible shimmer and video artifacts. The P-2400 IT eliminates AC ground loop hum while protecting critical AV equipment from surge damage.
- Live Sound & Touring — Touring engineers use the P-2400 IT to address AC ground loop hum from unfamiliar venue electrical systems. AC ground loop problems are especially common when mixing consoles and processors connect to different building grounds. EVS protection is critical when plugging into variable electrical systems.
- Home Studios — For home recording, the P-2400 IT delivers top performance with the lowest noise floor and eliminates AC ground loop hum. It removes hidden noise, revealing detail, dynamics, and room acoustics previously masked by EMI/RFI, common-mode noise, and AC contamination.
