Owner's Manual
Installation & System Wiring
It
is
important
to
read this manual thoroughly before starting
your
installation and always plan
accordingly. Before installing any Wavtech product, disconnect the negative (ground)
wire
from
the
vehicle's
battery
to
avoid damage
to
the vehicle
or
yourself. Following all guidelines
will
help provide
years
of
enjoyment
with
your
Wavtech
bassRESTOR
audio interface.
Ground Connection
(GND):
The
GND
terminal
must
be connected
to
a metal
part
of
the
vehicle
that
is
welded
to
the
vehicle body
with
ground plane back
to
the
main
battery
ground
attachment
point
(a
.
k.a
.
chassis ground). This
wire
should be a minimum
of
1
SAWG
and
as
short
as
possible
to
minimize
potent
ial
for
noise
to
enter
the
system. The chassis ground connection
point
should have all
of
the
paint
removed
and be scuffed
to
the
bare metal. The ground
wire
should be terminated by a ground specific interlocking
terminal such
as
the
included
EARL
terminal
or
ring terminal securely bolted
to
the vehicle
with
star
or
lock washer and
nut
to
prevent from coming loose. Avoid using factory ground points
to
reduce
the
chance
of
induced noise from
other
components.
Power Connection (+12V): The constant
power
connection should be made
at
the vehicle
battery
when
possible. For
direct
battery
connection, a 1-amp fuse
must
be installed in-line
with
the
power
wire
within
1
S"of
the
battery
and securely connected
to
the
positive
battery
terminal
bolt
with
a ring terminal.
If
connecting
to
another
available
constant+
12V
power
source, a 1-amp in-line fuse
must
be added
at
the
connection point. The power
wire
should be a minimum
of
1
SAWG.
Do
not
install
the
fuse
until
all
other
system connections have been made.
Speaker Level
Input
(SPK):
Connect
the
speaker wires
from
the
source
unit
to
corresponding terminals on
the interface.
Use
the
SPK
input
if
your
source
unit
is
not
equipped
with
RCA
outputs
. Always ensure
the
correct
polarity
of
each channel when making these connections,
as
failure
to
do
so can severely
effect
sound performance.
Remote
Input
(REM
IN):
If
the
source
unit
has a remote
output
wire
(provides +12V only when turned on),
connect
it
to
the
REM
IN
terminal.
If
a remote lead
is
unavailable, all Wavtech interfaces also provide
automatic
turn
-on via DC-offset and audio signal detection. While auto turn-on
will
work
in
most
applications, there may be some
cases
were a +12V
trigger
is needed
for
satisfactory results. These signal
detect
functions
can
also be individually defeated via internal jumpers (labeled
DC
and AUD)
if
necessary.
Remote
Output
(REM
OUT):
Use
the remote
output
to
provide a + 12V
trigger
to
turn
on amplifiers
or
other
components. This
+12Voutput
is generated internally by the interface when turned on
either
by
REM
IN
or
signal sensing, and
will
provide over S00mA
of
constant current
for
external devices.
Remote Level Control
(RLC)
: Connect
the
remote
to
the
bassRESTOR's
RLC
port
with
the
supplied
16.4ft/5m
cable. Plan cable routing before mounting
the
remote
to
ensure proper
length
.
If
additional
length
is
required, a standard a-conductor
CATS
or
CAT6
ethernet
cable
or
extension may be used. The
cable may also be shortened and re-terminated
with
a RJ45 connector and
ethernet
crimping tool.
