Connections & Functions
Œ
Power Indicator: This red LED indicates when the linkT 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.

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 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
setting. Dynamic music signal peaks are allowable up to 40Vrms, but will be
clipped. Use this input if your source unit does not have RCA outputs.
RCA Input Jacks: For left and right channel low level (a.k.a. line level) signal
connections to the source unit. Input signals ranging from 0.5Vrms to 5Vrms
will produce up to 10Vrms RCA output at maximum to minimum gain setting,
individually adjustable per channel.
‘
RCA Output Jacks: For left and right channel line level signal connections to
your amplifier(s). Use quality interconnects to ensure stable connections and
minimize the possibility for induced noise.
’
Mounting Tabs: These mounting tabs are pre-attached and should be used
to properly secure the linkT during installation with screws or cable ties.
They are removable if the unit can be safely secured by another method.
