AC INPUT connector - Accepts nominal AC power sources of 117 volts or 230 volts.
REMOTE BYPASS connector - Provides for the control of the BYPASS/IN function via a remote
contact closure.
LEFT INPUT connectors - Electronically balanced, bridging, line level inputs. XLR pin 1 is ground,
pin 2 is high, and pin 3 is low. The 1/4" connector’s sleeve is ground, ring is low, and tip is high.
LEFT OUTPUT connectors - Electronically balanced, low impedance, line level outputs. XLR pin 1
is ground, pin 2 is high, and pin 3 is low. The 1/4" connector’s sleeve is ground, ring is low, and tip
is high.
RIGHT INPUT connectors - Electronically balanced, bridging, line level inputs. XLR pin 1 is
ground, pin 2 is high, and pin 3 is low. The 1/4" connectors sleeve is ground, ring is low, and tip is
high.
RIGHT OUTPUT connectors - Electronically balanced, low impedance, line level outputs. XLR pin
1 is ground, pin 2 is high, and pin 3 is low. The 1/4" connectors sleeve is ground, ring is low, and
tip is high.
Note For optimum immunity to noise and radio frequency interference we highly recommend
connecting the 422 to balanced equipment, where possible. If this is not possible,
unbalanced connections are OK. Unbalanced connections via tip-sleeve (mono) 1/4" plugs
are easy to make via the 422's 1/4" input and output connectors.
