plifier by pure electronic circuitry
is available in the LRS family. This
connector is used for connection to
the 5E24 PEAK INDICATOR when
it is available.
11. SPEAKER TERMINALS
Connect the speaker system to
these terminais. Speaker cables
must have sufficient capacity for
carrying audio output loads.
Correct connection is very im
portant. Checks must be made
whether the right channel output
terminais are connected to the
right speaker, and the left channel
to the left speaker. Also correct
phase matching
is a
must. Caution is
neœssarv that the core lead is not
short circuited to any other termi
nais or cables. To connect the
speaker cable, strip off the shield at
the end of the cable for approxi
mately 10mm (3") and twist the
core leads. Turn the knobs on the
speaker terminais to the complete
counter-dockwise end ( 0 ) , and
insert the core leads into the termi-

The insertion of the(+) and the(-)
leads must be made simultaneously.
Then fasten the leads in the termi
nais by turning the knobs clock
wise.
The laï_out of the speaker
terminais is L (±), L

R (±), R0
from top to bottom.

"CONNECTION OF SPEAKER
SYSTEMS" section of this manual.
12. OVERCURRENT PRO
TECTION FUSE
This device is provided to protect
the amplifier from breakdown
caused by unexpected abnormal
current flow within the circuit.
Especially, it functions to protect
the amplifier when short circuiting
takes place at the speaker terminais
or cables of speakers. ln the event
sound playback is suddenly inter
rupted, immediately disconnect the
power plug from an AC power point
and check this fuse - - - turn the
fuse holder cap counter-clockwise
( 0 ) to remove the fuse. If it
was blown off, replace with a spare
provided. Connection to the power
point must be practised only after
check and correction of the cause
of overcurrent flow. The fuse used
is a quick-blow 5A capacity fuse.
The upside fuse is for the left chan
nel and the downside fuse, the right
channel.
13. AC MAINS POWER
CORD
Connect. the AC plug at the end
of this cord to an appropriate single
phase AC mains outlet in your
listening room.
For use
with
the modal 5C50 control (pre)
amplifier of the same LAS family.
which is of a DC amplifier, the
power plug of this cord can be con
nected to the AC OUTLET
(SWITCHED) of the 5C50 and
leave the power switch ON. By
this the ON/OFF switching of this
amplifier is coupled with that of
the preamplifier .
14. EXTRA AC OUTLET
You can supply AC power to
other audio equipment through
this outlet. The terminal (UN
SWITCHED) is independent of
the AC power switch of this ampli
fier. The maximum capacity is
500W.
Note that in some countries this
outlet is not provided, because it is
not allowed by law.
