line outputs. Pin 2 and 3 of the XLR jack carry the signal, pin 1 = N.C. or ground

dependingonthe position ofthe Groundswitch (46).

Youcaninsert thesignalsroutedthroughthese

outputs directly into a mixing console or recording gear equipped with balanced

inputs. The advantage of a balanced circuit is that this type of connection will not

createa groundloop,provided ofcourseit iswiredcorrectly. Dial inthe desired signal

You encounter something called a ground loop if your preamp is

connected to a mixing console or recording gear and pin 1 of both devices' XLR

connectorsserve asground terminals(the XLR Groundbuttonon the preampis set to

Ground to Pin 1). A ground loop is readily identified by the infernal humming

emanating from your speakers. Set this button to the position "Ground Floated" to

press if you need a lower level (up to -5 dB) to feed the signal to additional signal

This unbalanced ¼" line out jack carries the preamp's right channel signal. You can
