pass labs x-5 XLR jumpers

[ROLIKOV]

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 ?

Thanks

Kind regards

ROLI

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.
