Finns en hel del skrivet om den på olika forum. För mer information se länken. Ett batteri följer också med som är extra. Observera att impedansen ut från källan skall vara låg och ingångs impedansen på slutsteget typ 50k ohm eller mer. Jag har använt den mellan CD-spelare och slutsteg.
Passive preamps can be superbly transparent when the matching gear is right.
At kr3,000, this sits above the kr1,050 median and just over the kr2,668 75th percentile, so it reads as ambitious rather than outrageous. It is not a bargain on the face of it, but it may still be acceptable if the unit is in excellent condition and complete.
What makes a Lightspeed-style passive stage worth considering is the low-coloration, direct presentation and the way it can sound especially clean with a strong source and a power amp that has enough input sensitivity. The upside here is simplicity: no gain-stage haze, minimal parts in the signal path, and usually very little to go wrong. For a fairer buy at this level, I’d want clear condition details and assurance that all controls and connections are quiet and original.
Independent perspective — not a price guarantee. Always verify condition, accessories and provenance before purchase.
Lightspeed Technologies, founded in 1990 in Tualatin, Oregon, has built its heritage on enhancing educational environments through innovative audio solutions. Over three decades, the company has focused exclusively on classroom audio systems, prioritizing clear communication between teachers and students in K-12 settings worldwide. This American-rooted brand emerged to address the challenges of noisy learning spaces, evolving from early infrared and FM systems to integrated tools that support inclusive instruction.
The product lineup centers on instructional audio hardware tailored for schools, including speakers, microphones like REDCAT and REDMIKE, infrared receivers, public address systems, media connectors, chargers, infrared sensors, and connecting cables. These components deliver crystal-clear, low-volume sound for whole-group and small-group teaching, while integrating with life-safety and building communication systems. Unlike consumer hi-fi gear such as amplifiers, turntables, DACs, headphones, or high-end cables, Lightspeed's offerings emphasize practical, durable solutions for everyday classroom use.
In the market, Lightspeed holds a strong reputation as a leader in edtech audio, not in the high-end hi-fi or audiophile niche but as a reliable provider of award-winning systems that boost engagement, teacher vocal health, and accessibility for all students. Positioned for educational institutions rather than home enthusiasts or vintage collectors, it occupies a specialized, mid-tier segment focused on functionality and safety over luxury sound reproduction. If seeking consumer hi-fi, this brand does not align.
