At USD 68, this is a genuine bargain: it sits below the USD 75 25th-percentile mark and well under the USD 140 median from 208 comparable listings. For a working unit, the price leaves plenty of room for sensible testing or setup costs.
The QM-RMCRX-BA is a capable 2-Series control processor with Ethernet and QuickMedia integration, useful in older Crestron-based distributed-audio or presentation systems. Its built-in amplifier adds practical value where a compact all-in-one endpoint is needed, and these units can be worthwhile for completing an existing installation or sourcing a spare. Because the condition is unknown, confirm that it powers up, initializes correctly, communicates over Ethernet, and includes the required power connection and any system-specific programming before buying. At this price, though, it remains an attractive project or parts opportunity even if not fully tested.
Independent perspective — not a price guarantee. Always verify condition, accessories and provenance before purchase.
Crestron was founded in 1972 in the United States by George Feldstein and built its reputation in professional AV, automation, and control systems rather than in traditional consumer hi-fi. It is a privately held company headquartered in Rockleigh, New Jersey, and its core business has long centered on integrated technology for commercial spaces and high-end residential systems.
In audio, Crestron is best known for installation-oriented products: control processors, AV distribution, streaming audio-over-IP systems, amplifiers, and architectural speakers. Its residential audio line is built around the Crestron Home platform and DM NAX distribution hardware, while its speakers are typically developed with partners such as Origin Acoustics rather than sold as standalone audiophile separates.
In the market, Crestron sits in the premium custom-install and high-end integration segment, not the conventional hi-fi retail space. Its appeal is strongest among system designers, integrators, and affluent homeowners who want whole-house audio, automation, and discreet in-wall or in-ceiling sound, rather than collectors looking for turntables, headphones, or vintage separates. It is a niche but major brand in residential and commercial integration, with audio positioned as part of a broader control ecosystem.
