LIFT/GROUND
This switch allows you to lift the CABCLONE BALANCED D.I. Output’s XLR jack (PIN 1) GROUND, from Circuit
and Chassis GROUND and in many cases (but not all) remove hum caused by a ground loop. In silent recording environments every
little noise stands out and ground loops can produce one of the more common (and annoying) sources of hum and/or
buzz. It is not a cure-all to this common problem by any means, but it can often make a positive impact on the noise
floor and at least help you rule out one common source of “hum”.
That pretty much wraps up our tutorial of the MARK FIVE: 25’s features. Now it’s your turn to take this powerful tool
into your musical world and put it to use exploring uncharted frontiers. We sincerely hope it takes you places you’ve
never been and allows you to express in new and exciting ways. Learning it’s Controls and Features will make you
fluent in the language of TONE and enable you to roam wherever you feel inclined stylistically with confidence.
From all of us here at MESA/Boogie, welcome to the Family and we wish you many years of inspiration and enjoyment from your
new instrument.
