Introduction
Welcome
to
Wavtech, exceptional mobile audio integration products
for
audiophiles.
Our
products are
engineered
to
provide a
truly
remarkable listening experience. Built
for
the professional installer,
our
OEM
integration and signal processor models are simply the best solution available

0 Power Indicator: This red
LED
indicates when the
bassFREQ
is powered on. Once illuminated, there
will
be a
short
delay before audio signal
output
is
enabled. During
initial
power
connections,
it
may
illuminate
for
a
brief
period.
@Ground Jumper: For selecting between chassis, isolation
or
2000
for
the
internal audio signal ground.
Chassis
ground
is
the
default
setting and ideal
for
most
applications due
to
the
differential
input
stage. In
the
rare
case
there
is
system noise present
after
all
other
installation countermeasures,
changing this
jumper
to
ISO
or
2000
may reduce
or
eliminate the noise.
0Power Supply Terminal: For +12V battery, chassis ground, remote
input
and remote
output
wire
connections. A minimum
of
18AWG wire
is
recommended
for
power
and ground connections. Always
protect
the
+ 12V
power
wire
with
a 1-amp fuse.
8Speaker Level
Input
Terminal: For
left
and
right
channel speaker level (a.k.
a.
high level) connections
to
the source.
Input
signals ranging
from
2Vrms
to
20Vrms
will
produce up
to
10Vrms
RCA
output
at
maximum
to
minimum gain.For factory amplifiers
with
more than 20Vrms signal
or
if
the
bassFREQ's
output
is
too
high
for
the connected
aftermarket
amplifier(s)
with
all gains
at
minimum, internal
jumpers
are available
to
reduce the
input
sensitivity range by
half
{-6dB)
to
4Vrms up
to
40Vrms.
0RCA
Input
Jacks: For
left
and
right
channel
low
level (a.k.a. line level) signal connections
to
the
source
unit
.
Input
signals ranging
from
O.SVrms
to
SVrms
will
produce up
to
1
OVrms
RCA
output
at
maximum
to
minimum gain. These inputs are differential,
but
may be
set
to
unbalanced via internal jumpers
if
required
for
a particular source
or
to
midigate
potential
for
coupled noise
if
left
floating.
0Remote
Level
Control
Jack: This
RJ45
jack is
for
connecting the remote level
control
to
the main
unit
with
the supplied cable. A standard
ethernet
cable may also be used.
&RCA
Output
Jacks: These mono line level
outputs
are
for
signal connection
to
your
amplifier(s).
Each
output
is
an
independent internal circuit,
both
capable
of
driving
multiple
amplifiers simultaneously.
Use
quality interconnects
to
ensure stable connection and minimize
the
possibility
for
induced noise.
@Mounting
Tabs: These mounting tabs are pre-attached and should be used
to
properly secure the
bassFREQ
during installation
with
screws
or
cable ties. They are removable
if
the
unit
can be safely
secured by
another
method.
0Remote
Housing: This 2-piece housing design provides
both
convenient
mounting and simple dissasembly
for
customization. The integrated screw
mount
tabs are pre-scored
to
aid removal
if
securing
by
another method,
and
the
lower
housing
can
be detatched by removing
the
two
top
screws.
For panel mounting, the housing can be completely disassembled by also
removing the knob,
shaft
nut
, and circuit board screw.
If
the
housing
is
removed,
it
is recommended
to
protect
the
exposed
PCB
with
heat shrink.
