LINE OUT
The MA-2.2B has two output connectors. In standard configuration the output is
unbalanced to avoid the extra amplifier stage required and maintain the shortest
possible internal signal path.
The XLR male output connector is wired as follows;
Pin 1 = Chassis Ground
Pin 2 = Signal Hot (+)
Pin 3 = Signal Ground (common)
If you treat the MA-2.2B output as balanced and use normal XLR balanced leads there
should be no problems connecting to other gear.
If the optional output transformer is fitted (see the section on Options) the XLR is wired
as follows;
Pin 1 = Chassis Ground
Pin 2 = Signal Hot (+)
Pin 3 = Signal Cold (-)
LINE OUT DIRECT
This TRS ¼” jack socket carries the unbalanced output signal even if the optional output
transformers are fitted, and it is wired as follows;
Tip = Signal Hot (+)
Ring = Signal Ground (common)
Sleeve = Chassis Ground
As for the XLR output, if you treat the direct output as balanced and use normal TRS
balanced leads there should be no problems connecting to other gear.
Please Note
The Chassis Ground connection is intended for connecting cable SHIELDS. When
connecting the MA-2.2B output to other devices, it is not always necessary to connect
the shield at both ends of the cable. This may help prevent earth loops occurring. The
mic input Signal Ground however is always connected at both ends to ensure correct
shielding of the cable and mic body.
The Signal Ground source can be selected HARD or SOFT, see the Controls and Indicators
section.
