10421 GAC-2 V1 Similar to GAC-2, improved noise performance
GAC-2 V1 (10421) also sold under P/N 10420 Balanced double shielded audio cable! Variation to our most popular GAC-2 microphone cable with the same construction as GAC-2 but the PVC-separation (4) has been made out of conductive material to improve the mechanical/noise performance. To improve the capacitance of the cable we have chosen to use PE as isolation material. This is the perfect 2-wire microphone cable without compromise with conductive seperation tube for minimal handling noise for film microphone booms.Similar cables are available as ultrastrong PUR (10502) version and as industrial standard cable for a lower price (10405).
LFOC higher grade copper at best standards for best performance.

Balanced XLR wiring instruction:
Pin1= shields, Pin2= brown (Signal+), Pin3= white (Signal -).
Should space not allow to solder all strands of the many shields, you can put only each a few strands of each layer of the shields to ground Pin 1. Cut away any spare strands from the shields and secure that no loose strands are hanging around. Use a shrinking tube to avoid short ciricuits. We do not recommend to put any ground to the body shell on either side of your XLR line. The connector shell will get to ground once plugged into a receptacle.
Having your shields put on the connectors shell is dangerous! Imagine, a loose cable can make contact with another loose cable connector having a different ground potential. So the metal connector is conductive and shall not carry your audio ground used on the shieldings of your audio signal. It can interfere with other "grounds" such as video, data of power grounds, which are potentially different! So keep "grounds" separate!
RCA/Phono/Jack unbalanced wiring using balanced wire:
Many clients use our balanced 2 conductor cable also for unbalanced interconnects. In this case we recommend to only use 1 conductor (brown) for your signal and put all other wires or parts thereof to ground with the shields. This will increase your noise protection! However for unbalanced application we do have our perfect unbalanced wires 1001x, and 1000x.
Unbalanced Stereo & 2 Channels (loop) application:
We actually do not support the idea to use a 2 conductor cable for stereo unbalanced wiring, however it will be done and can be made with acceptable compromise regarding crosstalk and similar. Again all the shields to ground but not to the body shell of your XLR connector. Check our perfect stereo cables 12001/13001 or our conductor shielded Starquad 11301 for real quality stereo wiring!
