Power 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 (a.k.a. high level) input
connections to the source. Input signals ranging from 2Vrms to 20Vrms will produce up to 10Vrms
RCA output at maximum to minimum gain setting. Dynamic music signal peaks are allowable up to
40Vrms, but will be clipped.

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.
'
RCA Output Jacks: These eight channels of RCA line level outputs are for signal connection to your
amplifier(s). CH3/4, CH5/6 and CH7/8's output will depend upon which INPUT CH setting is selected
for each pair (see pg3), while CH1/2 will always pass through its input signal directly. When selected,
the AUX input will supply left/right stereo signals to all four pairs of outputs. 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 supplied cable to the external multi-
function remote controller. 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.
