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 from maximum to minimum gain. For factory amplifiers
with more than 20Vrms signal or if the linkDQ’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.
Remote Level Control Jack: This RJ45 jack is for connecting the
linkRC remote level controller (sold separately) to the main unit via
its supplied cable or any standard ethernet cable.
‘
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. These inputs are differential, but may
be set to unbalanced via internal jumpers if necessary.
’
RCA Output Jacks: For left and right channel line level signal
connections to your amplifier(s). 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 linkDQ during installation with
screws or cable ties. They are removable if the unit can be safely
secured by another method.

Installation & System Wiring
It is important to read this manual thoroughly before starting your
installation and always plan accordingly. Before installing any Wāvtech
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 Wāvtech
linkDQ 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 18AWG and
as short as possible to minimize potential 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 a 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.
