Recommended Input Wiring Methods
These are the best ways to connect sources to the mixer.The mixer input is always balanced. From the drawings below choose the wiring method for your input device (either balanced or unbalanced).
Balanced Source to Balanced Input - Method 1 (Normal)
Shown below is the normal wiring method for a balanced source device. It has +6 dB gain and excellent ground current and noise rejection.

Balanced Source to Balanced Input - Method 2
If the method above does not work in your application, use the wiring shown below. This method can solve certain ground loop problems. It has +6 dB gain and good noise and ground loop rejection.

Unbalanced Source to Balanced Input - Method 1
For an unbalanced source device, the drawing below shows the best wiring method. Because of the design of the mixer, this wiring provides a slight (+6 dB) boost, and moderate noise and ground loop rejection.

Unbalanced Source to Balanced Input - Method 2
For an unbalanced source device, the drawing below shows an alternative wiring method. Because the grounding of the minus input is not to the mixer ground, this method does not provide the +6 dB boost. Ground current and noise rejection is good.
