The PR-5 is a genuinely accomplished tube excitation unit from Line Magnetic, designed as a dedicated power supply for low-voltage field-coil speakers. The PR-5 brings Line Magnetic's considered engineering to dedicated field-coil excitation duty at the more accessible end of the brand's PR-series catalogue.
Key specs that matter
Power input accepts 220-240V AC or 100-120V AC, each at 50-60Hz. Applicable voltage spans a high terminal range of 6-23V at 0.5-2A DC, alongside a low terminal range of 2.6-8V at 0.25-2.5A DC. At 290 x 210 x 360mm and 10kg, the PR-5 maintains a genuinely manageable exciter-power-supply chassis reflecting Line Magnetic's considered hand-built engineering standards.
Sound and use context
Given Line Magnetic's positioning of the PR-5 within its broader field-coil-excitation product ecosystem, expect a genuinely stable, dual-terminal excitation supply consistent with the considered engineering standards the brand applies across its power-supply catalogue.
Pairing
The PR-5's dual high- and low-terminal voltage ranges suit low-voltage field-coil speakers requiring flexible excitation-voltage matching from a dedicated tube-based supply.
