Default pass labs x-5 XLR jumpers

Hello ,

I connect the PASS X-5 ( five channels ) power with MERIDIAN 561 pre/ processor .

It is reccomended in the PASS user manial - to put XLR connectors - jumpered pin 3 to pin 1 in each terminal when using the unbalanced inputs ( as i use now ) .
Can anyone explain what will be the benefit using these jumpers ? is it necessary ?


Kind regards

Those jumpers are more than necessary, they are mandatory!
They short the neg. input (not used) to gnd.

The amp won't break, but it will sound terrible.
