impedance taps. We suggest listening to each of the three taps to select
the best match for your speakers.
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 should move synchronously-in
and out together. Terminals on the speakers are usually coded-one
designated "C", "earth", "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 4,8, or 16 ohm amplifier terminal
marked on each channel to the red or "+" coded terminal on each
speaker, and connecting the "C" tap to the black or "-" coded terminal
on each speaker.
In phase connection of the speakers can be readily ascertained by ear.
With the preamplifier mode switched into the MONO position, play a
record of a solo vocalist. With the speakers in phase the voice should
be clearly focused between the two speakers. With the speakers con-
nected 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.
