11401 GAC 4/1 UltraPro Magnetic shielded

New in November 2025 available:
Magnetic shielded version of our top of the line Audio Signal Cable:

Gotham "Star-Quad" cables are the most advanced microphone cables presently available. We have combined an ultraflexible PVC-jacket, low capacitive PE insulation, " Reussen shielding" and quad (4-conductor) construction for a truly professional cable at an affordable price. The "Star-Quad" concept is known and recommended where the RF-rejection is the most important factor and where very long cable runs are needed. As we use each 2 conductors for low and high signal, we reduce the signal loss by 50% and due to the offset of the incoming RF-signal by the way the 4 conductors are twisted, the RF-rejection is over 130dB (25 kHz). The exclusive Reussen shielding does its part of these features as well.
LFOC higher grade copper at best standards for best performance

4  different shielding technologies are matched and combined with this product to get the most comprehensive construction for Balanced Audio signals.

-Starquad Construction for balanced audio application
-Conductor Shielding (each core conductor is 2 times shielded)
-K6160 Polyester nonwoven thermally bonded, both sides copper coated conductive viscose shield on the conductors and overall.
-Reussen Shield with 2 times 100% coverage with copper strands opposite wound over all construction.
-Mu-Metal Tape to serve an additional magnetical overall shield

11401 is a starquad balanced single channel  5 times shielded audio cable! Ultraflexible professional audio cable for microphones. 'Double Reussen shield', velvet matte non-light reflecting PVC-jacket material.  A unique construction new invented by Gotham design.
Each of the 4 conductor is shielded with a lap shield 100% covering copper wires (7) (Reussen shield) plus a conductive separation layer (6) (Aluminium coated Poyester ). This conductor is twised in starshape around conductor nr 2/3/4 and turn ist holded in place with another aluminium coated layer (4), followed by Gotham's unique double Reussen shield. This cable is absolutely uncompromised to acheive maximum shielding possible while the flexibility and durability is still very good and the cable can be used in mobile applications as well.
One can also use the cable as a 2 channel balanced cable giving still perfect crosstalk and shielding of each channel!
