Connecting Instructions - Kenwood KR-4070 Instruction Manual

CONNECTING
SPEAKER CONNECTION
In connecting only one pair of speakers, con-
nect the right speaker to [R] and the left speaker
to [L| of the SPEAKERS A terminals. Should (+)
or (—) of either right or left channel be reversely
connected, sounds at the center section will be
adversely affected by the lack of separation. To
connect an additional pair of speakers, connect
the right speaker to [R] and the left speaker to
of the SPEAKERS B terminals.
Sound cannot be heard when the SPEAK-
ERS switch on the front panel is set to the A+B
position and only one pair of speakers (connected
to either SPEAKERS A terminals or B ones) are
used. This is because A and B speaker circuits are
in series and is not an indication of any trouble.
When connecting the speaker leads to the
speaker terminals, make sure that the bare wires
at the tips of the speaker leads do not touch the
adjacent terminal.
{t is recommended that the wires of
individual speaker lead tips are soldered or they
are stranded together to eliminate any possibility
of short-circuits forming in the speaker connecting
network.

NOTE:
The impedance of each speaker should be 4 ohms or more
when only one pair of speakers are used or when two pairs
of speakers are simultaneously used (A+B).
RIGHT
PHASING OF THE SPEAKERS
Speaker phasing can be determined in the following manner:
1. Set the SELECTOR switch to FM (MONO).
2. Adjust the VOLUME control to the desired listening level.
3. if the sound comes 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.
