Output Cable Considerations
The model A 5360's outputs are wired in parallel: either the XLR-type OUTPUT jack or the 1/4" stereo phone jack are
capable of driving a 600Ω load. The phone jack TIP (+) connection is internally wired to the XLR pin 2, the RING (-) is wired
to pin 3, and the SLEEVE (shield) is wired to pin 1.
Grounding
For maximum hum rejection with a balanced source, avoid common grounding at the A 5360's input and output. Most
balanced (3-conductor) cables have the shield connected at both ends. This can result in ground loops which cause hum.
If hum is a problem, try disconnecting the shield on one or more of your cables, preferably at the input of a device, not at
the output: Ground the shield of the input cable at the source device (leaving it unconnected at the A 5360's INPUT) and
ground the shield of the output cable to the ground terminal of the A 5360 (leaving it unconnected at the receiving device).
The shield is pin 1 on the XLR, SLEEVE on a 1/4" TRS.
