Rear Panel Layout
Figure 1: 330A Backpanel
When you’re using the balanced XLR inputs, you
must first remove the factory installed “dummy”
XLR jumpers (see figure 2 below) from the back
panel XLR connectors and store them in a safe
place. This jumper is required ONLY when using
the single-ended RCA inputs. When you decide
to switch to single-ended input mode, you must
reinstall the XLR jumpers (between pins 1 and 3)
exactly as shown below: The left side of the rear panel has a pair of 12
Volt triggers, each on a 1/8” mini-jack; one input
and one output, the latter for use if you need to
“daisy chain” a second power amplifier on the
same trigger circuit. Immediately to the right of
these 12V triggers is an RS-232 input on a DB9
connector.
In the middle of the rear panel you will find a
two (2) pairs of heavy duty gold-plated speaker
binding posts – one pair each for the left and
right channels.
On the far right side, you will find (from top
to bottom); The power “main switch”; The
“AC Fuse” socket cover and the “AC in” IEC
receptacle for the power cord.
The rear panel will look similar to Figure 1 (above). Each channel has one balanced (differential) input on an
XLR connector and one unbalanced (single-ended) input on a RCA connector. There is no switch to toggle
from balanced mode to single-ended mode. You may operate the amplifier in either mode, but only one mode
at one time.
