TELEFUNKEN STMC-15TRS 15 ft TRS Cable

Product overview

The TELEFUNKEN STMC-15TRS 15 ft TRS Cable is a 15 ft (4.6 m) TELEFUNKEN Studio Series TRS to TRS cable, American-made with four high-strand count copper conductors, a braided copper shield and 24k gold-plated connectors.

TELEFUNKEN builds the STMC TRS to TRS cable for line-level connections in the studio: audio interface outputs to studio monitors, outboard processors to converters, and patch bay connections. Its TRS (tip, ring, sleeve) plugs carry balanced line signals, and the premium 24k gold-plated connectors, silver solder joints and ultra flexible jacket keep those connections clean and dependable. A TELEFUNKEN cable tie wrap is included.

• Designed, manufactured and hand assembled in the USA

Studio Series construction

Inside the jacket, four high-strand count, high-purity copper conductors are each sealed in audiophile-grade, low loss polyethylene insulation, and the bundle is wrapped in a high density braided copper shield for maximum rejection of radio-frequency (RMI) and electromagnetic (EMI) interference. Low capacitance keeps transients and high frequencies detailed and transparent, and the audiophile-grade insulators ensure accurate signal transfer over the full length of the run.

TRS to TRS connectors

Both ends carry a 1/4-inch TRS (tip, ring, sleeve) plug, premium 24k gold-plated for reliable, low-resistance contact. TRS connections are used for balanced line inputs and outputs on audio interfaces, studio monitors, outboard processors, mixers and patch bays.

Made in the USA, backed for five years

TELEFUNKEN designs, manufactures and hand assembles the STMC Studio Series in the United States of America. Every joint is silver soldered for maximum conductivity and strength, and the ultra flexible construction lies flat and resists knots and tangling. Each cable is covered by TELEFUNKEN's 5 year "no fault" warranty.

One construction across the STMC range

The TELEFUNKEN STMC Studio Series is made as XLR, TRS to TRS, TRS to XLR male (TXM) and TRS to XLR female (TXF) cables, all with the same four-conductor copper construction, polyethylene insulation, braided copper shield and 24k gold-plated connectors. That makes it simple to wire a whole studio, from microphones and preamps to converters, outboard and monitors, to one consistent standard.

Choosing the length

TELEFUNKEN makes the STMC TRS in 6 ft (1.8 m), 10 ft (3 m), 15 ft (4.6 m) and 30 ft (9.1 m) lengths. At 15 ft (4.6 m), the STMC-15TRS is a practical studio length, reaching across a control room or from a live-room position to a wall panel or preamp.

Routing and care

Run signal cables away from mains leads and lighting power where possible, and cross them at right angles where they must meet. Leave a little slack at each connector so the plug is never under strain, label both ends with the length and destination, and store coiled cables in a dry place with the connectors protected from dust.
