Benchmark Studio&Stage™ Analog XLR Cables

Hand assembled in the USA with true silver solder

Benchmark Studio&Stage™ Analog XLR Cables combine the best cable, connectors, and construction techniques in order to offer performance that meets the demands of world-class studios, while providing the strength and reliability required for stage applications. Our professional cables are also well suited for hi-fi applications because they meet or exceed the electrical performance of the best high-end hi-fi cables.


This special adapter cable connects transformerless balanced analog outputs to unbalanced analog inputs.

Use this cable to connect the transformerless (electronically balanced) analog output from any Benchmark product (such as a DAC1 or DAC2) to an unbalanced analog input on a power amplifier or Hi-Fi "preamplifier".  This cable will work will all Benchmark balanced analog outputs. Please note that this cable will not work with the transformer-coupled analog outputs found on some non-Benchmark products because pin 3 of this cable is floating.  Do not use this cable with digital signals.

Special Wiring (pin 3 floating):

  • XLR pin 1 to RCA ring
  • XLR pin 2 to RCA center pin
  • XLR pin 3 - open 

Benchmark Adapter Cables

Benchmark Adapter Cables combine the best cable, connectors, and construction techniques in order to offer high performance and excellent durability. Canare StarQuad L-4E6S Microphone and Audio Line Cable is flexible, satin smooth to the touch, and extra strong. The cable offers excellent immunity to hum-inducing magnetic fields (due to 4-conductor StarQuad construction), excellent shielding from RF interference (due to high-density braided shield), very low handling noise (due to internal construction), excellent flexibility (due to 40-strand conductors and special super-flexible insulation), and extended frequency response (due to low capacitance). Benchmark Adapter Cables are handcrafted with true silver solder, using gold-contact Neutrik XX series connectors. The XX series are the most reliable XLR connectors available - providing excellent contact quality, strain relief, pullout resistance, and durability. Neutrik XXR color coding rings can easily be added to assembled cables if desired - order rings separately.  A Benchmark-branded sleeve is your assurance that you have purchased a genuine Benchmark Adapter Cable.
