D. INPUT AND OUTPUT
CONNECTIONS
CAUTION: When making connections to this component
or any other, make sure ttie power amplifiers are OFF and
the preamplifier is in the MUTE or STANDBY mode.
1. Connect the speaker cables to the output terminals of
each amplifier. The MDA-300/500s utilize two sets of
parallel 5 way binding posts for the left and fight amplifi-
ers. This con_figuration makes cable connections and-bi-
wiring simple.
NOTE: The binding, posts are of the highest quality but
w. ill break if over.tigla.tened. In..se.rt wire or spade lug into
the connector anc~ tigt~ten until there is no movement
from the cable.
CAUTION: Make sure all cable terminations are of the
highest quality, free from frayed ends, shorts or cold
solder joints.
2. Connect the interconnect cables from your preampli-
fier to the input of each MDA-300/500.
The wiring to and from the amplifiers, and all compo-
nents in general, should be arranged in a neat, organized
manner. Specifically, AC wires should be separated from
audio wires. This practice avoids hum or ottier unwanted
noise from being induced into the system.
The MDA-300/500s have balanced and single-ended
inputs. The balanced inputs use 3-pin XLR connectors
and the single-ended inputs use standard RCA connec-
tors.
CAUTION: Use only one input to the amplifier at a time.
The MDA-300/500s are shipped with. shorting pins in the
~LR inputs. These pins shoi~ld remain in the XLR inputs
it you are operating the MDA-300/500s in the single-
elided mode. When the shorting pin is inserted, pin 1 and
pin 3 are. shorted together. The sfiorting pins must be
removecl to connect the MDA-300/500s for balanced
operation.
