Connect adjacent instrument-audio equipment with a short, high-impedance cable path using the AT-GCH. Its 36 in length suits close-range connections between equipment that is installed in the same rack area, work surface, enclosure, or audio assembly. The 1/4-CH connection designation should match the interface requirement at the intended connection point before installation. Western Digital 158000-52 is specified as a high-impedance instrument cable rather than a general-purpose long-run audio lead. That distinction matters where the signal path calls for an instrument-cable connection and a controlled, short physical run. The cable length can reduce excess slack around closely grouped equipment while maintaining a direct connection path. Select this cable when the required installation calls for the AT-GCH designation, a 36 in reach, and the stated 1/4-CH interface designation. It is a focused interconnect for short instrument-audio links, not a substitute for a longer cable where equipment spacing exceeds its available reach. Verify the required endpoint interfaces and routing distance before placing the cable in service.
