CONNECTING INSTRUCTIONS
SPEAKER CONNECTING AND SPEAKER
SWITCH
In connecting only one set of speakers, con¬
nect the right speaker to right speaker terminals
and left speaker to left speaker terminals of "A"
speaker terminals. Should plus or minus of either
right or left channel be reversely connected, sounds
at the center section will be adversely affected by
lack of separation.
To connect additional set of
speakers, connect right speaker to right speaker
terminals and left speaker to left speaker terminals
of "B" speaker terminals.
When connecting the speaker leads to the speak¬
er terminals, make sure that the bare wire strands
at the ends of the speaker leads do not touch each
other or adjacent terminal.
It is recommended that the tips of the speaker
cord leads are soldered, or the strands of each
individual lead twisted together to eliminate any
possibility of short-circuits forming in the speaker
connecting network.
Note:
When only one pair of loudspeakers are used, please ensure
that the impedance of each speaker system is 4 ohm or more.
When two sets of speaker systems are being used at the same
time (A+B), please ensure that the impedance of each
speaker system is 8 ohm or more.
Remove insulation
from wire end.
Twist stranded wire.
SPEAKER LEAD WIRES
PHASING OF THE SPEAKERS
Speaker phasing can be determined in the following manner:
1. Set the MODE switch to MONO.
2. Set the INPUT SELECTOR switch to PHONO, and adjust the VOL¬
UME control to the desired listening level.
3. Play a familiar record.
4.
If the sound is coming directly from the front, the speakers are in
phase. If the sound comes from both sides and there is a noticeable loss
in low frequencies, the speakers are out of phase.
In this case reverse
the leads on one speaker.
