When feeding the amplifier from an unbalanced source, use either an XLk
connector or a standard stereo 1/4” phone plug and connect the signal "hot"
connection to XLR pin 3 or to the phone plug tip. Connect signal ground to
the XLR's pins 1 and 2 or to the phone plug's ring and sleeve. The latter may
also be accomplished by simply inserting a standard 1/4” mono phone piug,
which automatically connects ring and sleeve together.
In the special case where the amplifier is physically mounted in tiie same rack
with the signal source that is feeding it, you may wish to use an alternate
connection system to avoid ground loops: connect the signal hot to XLR pin 3
or to the phone plug tip. Connect signal ground to XLR pin 2 or to the phone
plug ring. Leave the XLR's pin 1 and the jack sleeve unconnected.
SPEAKER OUTPUTS
The speaker output connections are combination banana jacks/binding posts
spaced on standard 3/4" centers. Speaker connections may be accomplishec
either by inserting banana plugs or by feeding bare stranded wire into tue
binding posts.
