Owner's Manual

Introduction
Welcome to Wāvtech, 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 for unlimited sound
system upgrades while retaining the factory receiver.
ΠPower Indicator: This red LED
indicates when the link8 is
powered on. Once illuminated,
there will be a short delay
before audio signal output is
enabled. During initial power
connection, the LED may
illuminate for a brief period.
 Ground Jumper: For selecting
between chassis, isolation or
200Ω for the internal audio
signal ground. Chassis ground is
the default setting and is 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 200Ω may reduce or eliminate the noise.
Ž Power 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.
 Speaker Level Input Terminals: For up to eight channels of speaker level input connections to the
source. Input signals ranging from 2Vrms to 20Vrms will produce up to 10Vrms RCA output from
maximum to minimum gain. For factory amplifiers with more than 20Vrms signal or if the link8’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) for 4Vrms up to 40Vrms.
 Auxiliary Input Jack: This 3.5mm stereo AUX input is for the connection of a portable device such as a
smartphone or MP3 player, but may also be used for other low level (a.k.a line level) sources using a
3.5mm adapter. AUX may be selected as a separate source via the multi-function remote, or
programmed as the primary source for stand-alone systems where the speaker level inputs are not
used (see pg4). Input signals ranging from 0.5Vrms to 5Vrms will produce up to 10Vrms RCA output at
maximum to minimum gain setting. This input is differential but may be set to unbalanced via internal
jumpers (labeled BAL/UNBAL) if required for a particular source.
‘ CH1/2 Output Select: This switch allows CH1/2’s output to be selected between 1/2 for direct input
pass-through (default) or 7/8 to copy signal from CH7/8 internally after its summing stage. The latter
is particularly useful when summing 4-way systems for retaining remote level control over CH7/8
while also providing a separate summed full-range output from CH1/2.
’ RCA Output Jacks: These eight channels of RCA outputs are for signal connection to your s
amplifier(s). For a speaker level source, output from CH3/4, CH5/6 and CH7/8 will depend upon their
respective INPUT CH settings (see pg3), while CH1/2 is set by its output select switch (see ‘ above).
For an AUX source, left/right stereo signals will be routed to all four output pairs. Use quality
interconnects to ensure stable connections and minimize the possibility for induced noise.
“ Remote Level Control Jack: This RJ45 jack is for connecting the multi-function remote to the main
unit with the supplied cable. A standard ethernet cable may also be used.
” Mounting Tabs: These mounting tabs are for securing the link8 during installation with screws or
cable ties. They are removable if the unit can be safely secured by another method.
