NOTES ON THE SPEAKER SYSTEM
Special regard has been paid Io lone quality in Ihe circuit de¬
sign of this unit To make the most of this circuil design, we
recommend that you use the DIRECT SPEAKERS terminals
for Ihe speaker connection With I his connection Ihe output
signals bypass the headphone ctrcuil. speaker remote switch,
etc , thereby minimizing ihe deterioration ol the tone quality.
If you often enpy listening through headphones, however, use
the REMOTE SPEAKERS terminals for the speaker connec¬
tion instead, In this case, you can cut off the sound of the
REMOTE speakers with the SPEAKER REMOTE switch on
the front panel when you wish to listen through the head¬
phones only.
When 2 pairs of speakers are connected, one lo the DIRECT
and the other to the REMOTE SPEAKERS terminals, sound
can be heard from all the speakers. However, only the sound
from the REMOTE speakers can be cut off with the SPEAKER
REMOTE switch,
Connect speakers with an impedance of 4-16 ohms. If you
connect 2 pairs of speakers, use speakers of 0-16
ohms, (The speaker impedance is indicated on the speaker's
inscription plate or in the instruction manual of the speaker
system.)
NOTES ON SPEAKER CONNECTIONS
Connect the speaker cord of the right speaker to the RIGHT
terminals and the cord of the left speaker to the LEFT termi¬
nals of DIRECT/REMOTE SPEAKERS terminals on the rear
