Making Connections
Pick an Input
Choose the type of Input connection you wish to
use either BALANCED (XLR cable see Figure 05)
or UNBALANCED (RCA cable see Figure 04).
Set the
INPUT MODE
Switch to the type of Input
you wish to use. Slide the Switch towards BAL for
the BALANCED IN connection or UNBAL for the
UNBALANCED IN connection.
Using the cable appropriate to the Input you have
chosen, connect the MC830 to your Preamplifier.
Typically, the mono MC830 will be used in pairs
for a stereo setup. If this is the case, pay attention to
which MC830 is connected to the left and which is
connected to the right output of the Preamplifier.
“Figure 06– XLR pin diagram” on page 7 shows
the proper Pin configuration for an XLR Balanced
connection to the MC830.
Connecting a Loudpeaker
The MC830 is designed to power a four or eight
Ohm Loudspeaker. You will need quality speaker
wire.
