The Puritan Audio PB104-DC is a high-fidelity mains power purifier designed to help reduce electrical interference in audio and home theatre systems. It combines multi-stage power filtering, DC offset correction, surge protection and star-earthing design in a compact, shielded enclosure.
Designed for music enthusiasts and home theatre installations, it provides four power outlets for compatible audio-video components. The DC-correction circuitry is intended to reduce transformer hum caused by DC offset on the AC mains supply
Key Features
-
20 Independent Filter Elements: Multiple stages designed to reduce common-mode and differential-mode electrical interference.
-
DC Offset Correction: Helps rebalance the AC waveform by reducing DC components that can cause transformer hum.
-
Four 15A Power Outlets: Four outputs with independent re-filtering stages for differential-mode disturbances.
-
9,000-Amp Surge Protection Rating: Three-dimensional, non-sacrificial surge protection as specified by the manufacturer.
-
Star Earthing Design: Helps reduce ground-loop hum and electrical noise.
-
Shielded Enclosure: Electrically and magnetically shielded casing.
-
Premium Internal Wiring: Silver-plated oxygen-free copper (OFC) wiring with PTFE insulation.
-
Compact Construction: Designed to integrate neatly into hi-fi racks and home theatre equipment setups.
Designed for High-Fidelity Systems
The PB104-DC is intended for systems where several audio components share the same mains supply. Its filtering stages are designed to reduce electrical interference, while its individual output filtering helps limit interference travelling between connected components.
Suitable applications include stereo hi-fi systems, integrated amplifiers, preamplifiers, source components, DACs and home theatre electronics, subject to each component's power requirements.
DC Offset Correction
DC offset on the mains supply can contribute to mechanical hum in some transformer-based equipment. The PB104-DC incorporates circuitry intended to remove this DC component, helping transformers operate more quietly.
The audible result depends on the existing electrical supply and connected equipment; improvements in sound quality are system-dependent
Power Filtering and Equipment Protection
The PB104-DC combines interference filtering with a specified 9,000-amp repetitive surge-protection rating. Its four outlets use independent re-filtering stages to help reduce cross-contamination between connected devices.
It also features a resettable overcurrent protector. Surge protection does not guarantee protection against every electrical fault or lightning event, so appropriate installation and grounding remain essential.
