Physical location and cable "dress" can be an important factor

in minimizing

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 ART 108A Amplifier at

the RCA type connector 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 banana" plug. They will also accept spade lugs, bare wire,

or pin connectors.

In a stereo system, 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 available). 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.
