Physical location and cable "dress" can be an important factor in mini-
mizing hum pickup. The installation should situate the preamplifier well
away from the power amplifier, and power (ac mains) cords should be
dressed to remain at least 4" (100mm) away from input/output cables.
Connection
INPUT: Connect the preamplifier to your amplifier at the RCA type
connectors located on the back of the amplifier.
OUTPUT: Five way binding posts are provided for connection of your
loudspeakers, with correct spacing to accept a standard "double ba-
nana" plug. They will also accept spade lugs, bare wire, or pin connec-
tors. The two channels should be connected in correct "relative phase".
This means that when the same signal is applied to both channels, the
right and left channels speaker diaphragms will move synchronously -
in and out together.
Terminals on speakers are usually coded - one designated "C",
"ground", "-" or black, the other designated "+" or red. "In phase"
connection of the speakers can normally be achieved by taking care to
connect the wire from the "+" amplifier terminal to the red or "+" coded
terminal on each speaker, and connecting the "-" terminal to the black
or "-" coded terminal on each speaker.
In phase connection of the speakers can be readily ascertained by ear.
Listen to a recording of a solo vocalist (use a mono recording if avail-
able). With the speakers in phase the voice should be clearly focused
between the two speakers. With the speakers connected out of phase,
the voice will be diffused, with no identifiable source. Relative phase may
be reversed by switching the "+" and "-" leads at one speaker only.
