Also be sure 1o
speaker to
the LE
FT
the right-hand
to the
the VOLU|\ilË well
below this setting when lower-
ing
the cartridge: at normal
or
high volùmes
the
shock may damage
your
speakers despite the
protectrve
relay.
Use the BASS
and
TREBLE controls
to
give
the
most
pleasant
tonal balance. At low listening
volumes, the LOUDNESS
switch
will
qive
a
more
natural
tonal balance in the
ON
position.
On the
other hand,
at
higher
volumes, the
ON
position
gives
unnaturally exaqgerated bass
and treble
response.
The CA-410 is designed for
speakers
with
impedances between 4 and l6 ohms.
Use only
speakers
which
are rated to tâke the full 25 Watts
o{ CA 410 output
power,
or
set the
VOLU[/]E
so
that the
rated maximum
speaker input
power
is
not exceeded,
as
indicated
on the
meter
readings.
Speakers can be seriously damaged by even brief
overloads. Remember
that
with
4 ohm speakers
the reading must be doubled
(i.e.
if the meters
read
20 Watts,
the
real
power
is 40 Wattsi,
and
halved
for
16 ohm speakers.
Making the Speaker Connections
1. Strip
the insulated
covering
Trom
the speaker
connecting
cable for
approximately half
an
inch,
and twist
any stray ends
together. lf
possible,
apply solder to
the
exposed
half
inch:
stray ends
can cause
short-circuiting of
the
output
terminals, with
possible
damage
to the
CA-410
{although
it is well
protecïed
by
safety
relay). Push
the lever
beneath the
terminal as
shown in the diaqram,
and align the
inner and
outer terminal holes.
Then insert
the wire fully
home.
Release the lever,
and the wire end will
be
fully
and
firmly
gripped,
making
a
perfect
connectron.
2. Be careful
that the
terminals identified
by the
+
and
-signs
above them are connected with the
+
and
-
terminals
on the speakers.
A mistake in
this
polarity
can result
in
poor
bass response
The
output cable from the
turntable unit
should
be
connected to
the
PHONO
terminals.
Plug
the
pin
jacks
attached to the cables firmly
into the terminal
sockets, making
sure that the
left-hand
cartridqe output
is connected to
the
LEFT
(upper)
socket,
and the
right-hand
to
the
RIGÈT
(lower)
socket. Turntables are
usually
provided
with
a
third,
GROUND, line. Be sure
to
connect this to the GND terminal,
screwing down
the retaining nut firmly.
To enjoy record
audition, turn
the
INPUT
SELECTOR
switch to
PHONO,
turn
the
VOLUI\4E
welt
down, and
gently
lower
the cartridqe stylus
to
the record surface. Raise
the
volume
to the normal
listeninq level,
and note the selling. Always lowel
