21line in - The Line Input is a 1/4” balanced (TRS) 10k ohm input. The tip is the positive input, which should be used for unbalanced inputs. It has less gain than the XLR input and does not have Phantom Power available. The Mic and Line inputs should not be used simultaneously.

NOTE: Directly adjacent to the stereo inputs (rear panel) there are four channels of mono inputs. On these four channels, there is a combo line/mic input jack. The line input accepts a 1/4” balanced (TRS) input or 6.3 mm plug.

can be used as the channel’s input, such as when using an expensive, outboard tube mic preamp, for example.
In these cases, the Tip contact of the plug should not be connected. The signal from the external pre- amp should feed the Ring contact (the Sleeve contact is the ground return).
