Сетевые фильтры и HiFi-мебель — Line Magnetic PR-22

The PR-22 is a power conditioner and filter from Line Magnetic, a Chinese manufacturer better known for its vintage-inspired tube amplifiers and CD players, extending its catalogue into power-management accessories designed to complement a broader hi-fi system. The PR-22 targets buyers wanting genuine mains-noise filtering ahead of their audio equipment.

Key specs that matter

The unit functions as both a power conditioner and filter, providing three outlets for connected equipment. At 485 x 320 x 450mm and 39kg, the PR-22's considerable weight suggests substantial internal componentry, likely including isolation transformers or filtering elements consistent with serious power-conditioning design rather than a simple surge-protector strip.

Sound and use context

Expect the PR-22 to reduce mains-borne electrical noise reaching connected audio equipment, a genuine consideration for systems in electrically noisy environments or ones built around sensitive components particularly susceptible to power-line interference.

Pairing

With three available outlets, the PR-22 can serve a modest system comprising a source, preamplifier and power amplifier simultaneously, letting a buyer centralise power conditioning for their entire signal chain through one unit.

Alternatives

Line Magnetic's broader amplifier and disc-player catalogue, along with dedicated power-conditioning specialists offering similar filtering technology, provides alternatives for buyers wanting either more or fewer outlets, or a different approach to mains-noise reduction within their specific system. Line Magnetic's decision to extend its catalogue beyond amplifiers and disc players into power-conditioning accessories reflects a broader recognition that clean mains power meaningfully contributes to overall system performance, a consideration increasingly acknowledged even among manufacturers historically focused purely on amplification and source components.

Buyers already invested in Line Magnetic's broader tube-amplifier and disc-player catalogue may find particular appeal in extending that same brand relationship to power conditioning as well.
