Output Connections.
The amplifier
output
is brought to both a 1/4-inch
T/S
phone jack and to 5-way binding posts marked "SPEAKER"
(or "SPEAKERS").
With regard to the binding posts, each
amplifier channel has one red (+) and one black (—) terminal
for connection to the speaker load. In normal operation, the
(+) SPEAKER terminal has the same signal polarity as the tip
of the input phone
jack or pin 2 of the XLR
input (see
"MONO MODE CONNECTIONS" for an exception.)
Refer to the discussion of "Speaker Wiring" in the MORE
INFORMATION
ON SOUND
SYSTEM WIRING section of
this manual
for additional
information on calculating load
impedances, power loss in cables, and minimum wire gauge
recommendations.
NORMAL
CONNECTIONS
Connect the speaker load as illustrated below. The minimum
nominal load impedance in this mode is 4 ohms.
