INSTALLATION
Due
to
the
high
power
of
this
unit,
DENON
Power
Amplifier
needs
adequate
ventilation,
so
please
find
a
safe
position,
on
the
floor
or
trunk,
and
install
securely
with
self-tapping
screws.
(Fig.
1)
Avoid
any
locations
in
where
the
adequate
ventilation
and
the
highest
performances
could
not
be
obtained
as
follows.
1)
Near
the
vent
of
heater.
2)
The
location
which
allows
the
unit
to
be
exposed
to
the
sun.
3)
Closed
location
such
as
inside
the
glove
box
or
under
the
carpet.
4)
The
floor
near
doors
or
windows
which
would
expose
the
unit
to
rain
or
moisture.
5)
Near
the
pedals
of
driver
which
would
interfere
with
operation
of
vehicle.
6)
Weak
and
instable
position
which
cannot
support
the
heavy
weight
of
the
unit.
**
Remove
the
ground
cable
(-)
from
the
battery
before
installation
to
prevent
damage
to
unit
or
the
automobile’s
electrical
system
by
miss-connection.
If
the
unit
cannot
be
installed
securely
by
self-tapping
screws,
use
bolts,
washers
and
nuts.

Ground
Isolation
Amplifier
Due
to
isolation
of
the
ground
in
the
amplifier,
you
can
now
enjoy
hi-fi

in
your
car
with
a
minimum

Now
you
can

by
just
turning
on
the

Since
there
is
no
longer
any
need
to
switch
the
amp
individually,
you
may
place
it
anywhere
in
the

whether
within
or
beyond

CONNECTIONS
&
OPERATION
After
the

is
securely
instal-
led,
make
the
connections
as
follows.
1)
Connect
the
pre-out

your
component
to
the
input
of
DCA-800
Connect
the
speaker
wires
to
the
speaker
terminals
of
DCA-800.
*
Make
sure
the
polarity
of
left
and
right
speaker
line
is
observed.
*
Never
connect
the
speaker
wirers
of
each
speaker
together.
*
Never
make
the
plus
and
minus
wire
short-circuit.
*
Never
connect
the
speaker
wirers
to
the
car
chassis.
Secure
the
ground
wire
to
a
clean
bare
metal
spot
on
the
car
chassis.
Make
sure
paint
or
coating
is
scraped
away
for
best
connection.
(The
wire
gauge
should
be
10~12
AWG.)
Connect
the
remote
cord
to
the
remote
control
terminal
of
your
indash
player.
‘
(The
wire
gauge
should
be
18
AWG.)
Connect
the
battery
cord
directly
to
the
positive
(+)
terminal
of
battery.
(The
wire
gauge
should
be
10~12AWG.)

type
accommodating

digital
source
in
the
input
first
stage
of
IC601,

Also,
in
the

employs
a
durable,

which
permits
high-output
sound
reproduction
having
a
high-steepened,
high-graded
quality.
@
Sub-woofer
A
sub-woofer
signal
is
feasible
by
using
VR603
to
boost
within
the
range
of
0
~
+16
dB
to
make
balancing
with
the
other
channels
when
sub-woofer
input
selector
SW601
is
set
at

Also,
this
signal
is
processed
with
a
-18
dB/Oct
low-pass
filter
composed
of
IC606.
The
filter's
cut-off

Controlling
Circuit
IC801
(4PC494C)

When
REMOTE

ON,
causing
TR818,
819
turn
ON
and
the
Pin

is
supplied
to
the
power.
Upon
the
power
supplied,
the
standard
voltage
(5V)
which
is
built
in
IC801
emits
from
Pin
@
and
impressed
to
Pin
@
through
C808.
After
that,
the
voltage
at
Pin
@
gradually
reduces
voltage
to
ground
level
with
the
time
constant
of
C808,
R817,
however,
with
this

the
pulse

expands.
Accordingly,

Toroidal
Transformer
T801
of
this

is
adopting
a
small,
highly
efficient
toroidal

and
therefore
the
stable

be
supplied

COOLING
FAN
Acooling
fan
is
newly
employed
to
this
unit.
This
fan
starts
running
when
the
heat
sink
temperature
becomes
approx.
70°C
to
lower
the
temperature

PROTECTOR
CIRCUIT
@®
Protection
of
Speaker
C614
(uPC1237)
searches
various
abnormalities
and
executes
protective
operations.
@
Overload
Censoring
When
shortcircuit
or
overload
of
speaker
terminals
occurs,
current
at
(R630A
(B,
C,
D,
E,
F)
increases
causing
voltage
rise
of
this
resistance,
and
TR6O6A
(B,
C,
D,
E,
F)
turns
ON.
After
this,
due
to
turning
ON
of
TR608,
voltage
at
No.
6
terminal
of
IC614
increases
by
approximately
24V,
and
relay
(RL601)
turns
OFF
and
separates
the
speaker
from
the
amplifier.
@
DC
Voltage
Sensoring
Speaker
terminal
voltage
is
normally
approximately
OV
(DC).
However,
when
DC
voltage
comes
out
due
to
some
accident,
the
speaker
is
separated
to
prevent
from
breakage
or
burning
damage.
if
DC
voltage
appears
on
the
speaker
terminal,
it
will
be
added
to
No.
2
terminal
of
IC614,
and
the
voltage
at
No.
6
terminal
is
raised
up
to
approximately
24V,
thus
the
relay
(RL601,
602,
603)
turns
OFF.
e@
Acc
OFF
Sensoring
Acc
voltage
is
sensorate
via

which.are
connected
to

4
terminal
of
IC606,
and
the
relay
(RL601,
602,
603)
rapidly
turns
OFF
as
soon
as
Acc
becomes
OFF.
@
Thermal
Protection
When
temperature
inside
the
unit
rises,
resistance
of
thermistor
(TH802)
is
weakened
and
TR802
becomes
ON,
then
1C801
stops.
In
case
of
abnormal
high
temperature,
resonance
of
IC801
stops
and
then
DC-DC
converter
circuit
will
be
closed.
@®
Protection
Against

Excess
of
Primary
Voltage
If
a
16V
or
higher
voltage
applies
to
the
battery
terminal

happen,
the
voitage
is
impressed
to
TR817
via
ZD801,
R841
and
TR817,
816
make
conduct.
Then,
IC801
stops
the
output
to
protect
against
abnormal
rise
of
the
secondary
side
voltage
and
breakdown.
