Product description

Blue Jeans Cable LC-2 Stereo Audio Cables

BJC's Proprietary Design

Our stereo audio cables are manufactured in our own shop in Seattle, Washington, using our own proprietary cable stock, the BJC LC-2 . The LC-2 design has the geometry of a coax, but with extreme low capacitance and heavy, high-conductivity shielding: two bare copper, 95% coverage braids layered one over the other. This both presents the best shielding available at analog audio frequencies and gives a low-resistance path between devices to prevent ground loop hum. The two cables in the pair are separate -- not joined together -- for maximum flexibility.

An update to a classic

Our LC-2 cable is a slightly updated version of our classic LC-1: a bit rounder in profile, and slightly lower in capacitance. It's the same design concept, just with a couple of updates in implementation.

LC-1 Design Characteristics:

• Solid 25 AWG copper center conductor
• Thick foamed PE dielectric for low capacitance
• Double-braid shielding: two 95% coverage bare copper braids
• Taversoe 7 RCA plugs designed specifically to fit this cable
• High-flex PVC outer jacket

LC-2 Design Notes: What Makes a Good Audio Cable?

When we entered the wire and cable business, we were not satisfied with the cable designs in use for analog unbalanced ("RCA") audio. Indeed, it seemed to us that, design-wise, this was a neglected product: solutions were either inappropriate (e.g., using balanced-type cables in unbalanced configurations), or relatively ineffective (e.g., traditional poorly-shielded small conductors), or, at best, were simply not quite optimized for analog audio (e.g., 75 ohm coaxial-type designs, which had the right geometry but were designed for RF).

Two considerations dominate unbalanced audio quality, and these were the focus of our design: first, low capacitance to prevent high-frequency rolloff; and second, high shield effectiveness at analog audio frequencies. For the first, a small center conductor in a very foamy dielectric was the solution; for the second, our tests showed that nothing beat two heavy, high-coverage copper braids, one on top of the other.

From Spool to Finish: Attention to Every Detail

The Connector

No stock connector fits this cable, so we designed our own. The Taversoe 7 RCA connector is a perfect fit to LC-2. It's a three-piece crimp design for high mechanical and electrical stability, and it incorporates a leaf-spring outer contact which provides excellent grip, but no over-grip, of the RCA jack.

Precision Manufacturing

No offshore assembly here: every LC-2 cable assembly is produced by skilled American workers in our own shop in Seattle, using the finest Swiss-made Schleuniger cable stripping machines and 3-ton pneumatic presses: the same quality machines and processes used for broadcast-industry cabling. Skilled workers, the best materials and the best processes add up to a fine, precision-made product with high quality and consistency.

The Final Product: Quality and No Nonsense.

The result is an RCA analog interconnect of unique design and engineering, optimized for line-level analog audio. We make no extraordinary claims for it; what we say is that it is designed to do a simple job well, and we think it succeeds. Try it, and we think you will agree.

Blue Jeans Cable: Quality Cable Manufacturing in Seattle, Washington

Blue Jeans Cable has been manufacturing quality cable assemblies for the broadcast industry and for home audio and theater applications for twenty years. The great majority of our products are manufactured in our own shop, right here in Seattle's Interbay neighborhood, and our product line includes a variety of unique offerings like LC-2 Audio Cable and our Ultrasonically-Welded speaker cables: our object is to bring the best in engineering and manufacturing quality to consumer products -- no extravagant claims, nothing but well-made, reliable, engineering-based performance.

• UNIQUE DESIGN: LC-2 isn’t a standard stock cable; we designed it specifically to optimize performance in unbalanced (“RCA”) analog audio, with coaxial geometry but with lower capacitance and better shielding than any ordinary coax.
• HEAVY SHIELDING: LC-2 is shielded with two high-coverage bare copper braids, one laid directly over the other. This provides the best possible shield performance at audio frequencies and lowest resistance to help prevent ground loop hum.
• LOW NOISE: Not only does our shield configuration provide effective EMI reduction, but it also avoids the problems with triboelectric noise which “combination” shields can cause – particularly important with low signal levels such as phonograph connections.
• LOW CAPACITANCE: Capacitance in interconnects can cause high-frequency rolloff. The large spacing between shield and center conductor, and the use of a highly foamed dielectric, keep LC-2’s capacitance around 12 pF/foot.
• HIGH FLEX: LC-2 is a thick cable – but is surprisingly flexible, with a soft PVC jacket and foam dielectric.
