CONNECTIONS TO COMPONENT PARTS

SPEAKER CONNECTIONS

Special circuitry in the KR-5150 receiver makes it possible to hook up three
sets of speakers le.q., in different rooms). Any spedrers with an impedance
between 4 and 16 ohms can be used.

In connecting only one set of speakers, connect the new speaker to ridit
speaker terminals and left speaker to left speaker terminals of "A terminals
Should plus or minus of either rid-it or left channel be reversely connected, sounds
form the center section will be affected by a lack of separation. To connect a
second set of speakers, connect rid-It speaker to right speaker terminals and left
speaker to left speaker terminals of "8" terminals. In the same manner, athind set
of speakers can be connected to C" terminals.

A - B SPEAKERS" position of the SPEAKER selector switch will not work
unless both A speakers system and 8 speakers system are connected. Likewise "A -
C SPEAKERS" position of the SPEAKER selector switch will not work unless both
A speakers system and C speakers system are connected.

PHASING OF THE SPEAKERS

Correct phasing is important in a stereophonic system. lithe speakers are out
of phase, they will work in opposition of each other and there will be a noticeable
loss in low frequencies. Use the following procedure to make adjustments:

1. Set the SELECTOR switch to PHONO 1 (or PHONO 2/MlC), MODE switch to
MIX and set VOLUME for desired listening level.

2. Play a monophonic record containing heavy bass passages

3, After your speakers are connected, listen to the intensity of the bass tone.
Then reverse the lead connections of the speakers and listen to the sound again.
(See Figure 2). The position of the lead connections where the bass intensity
was the greatest is the proper one and the speakers will then be permanently in
phase.
