WARNING
CAUTION
This symbol means important instructions.
Failure to heed them can result in serious injury or death.
This symbol means important instructions.
Failure to heed them can result in injury or property damages.
• DO NOT DRIVE WHILE DISTRACTED. Any function that requires your prolonged attention should not be performed
while driving. Always stop the vehicle in a safe location before performing any such function. Failure to do so may
result in an accident.
• KEEP THE VOLUME AT MODERATE LEVELS WHILE DRIVING. Excess volume levels can obscure sounds such as
emergency vehicle sirens or road warning signals and may result in an accident. Continuous exposure to high sound
pressure levels may cause permanent hearing loss. Use common sense and practice safe sound.
• FOR USE WITH 12V NEGATIVE GROUND VEHICLE APPLICATIONS ONLY. Using this product other than in its
designed application may result in fire, injury or product damage.
• MAKE THE CORRECT WIRING CONNECTIONS AND USE PROPER FUSE PROTECTION. Failure to connect wiring
correctly or use appropriate fuse protection may result in fire, injury or product damage . Ensure proper fusing of all
system power wiring and install a 1-ampere in-line fuse (not included) with the +12V lead to the unit’s power supply
connector.
• DISCONNECT THE NEGATIVE BATTERY TERMINAL BEFORE INSTALLATION. Failure to do so may result in fire,
injury or damage to the unit.
• D O NOT ALLOW CABLES TO BECOME ENTANGLED IN SURROUNDING OBJECTS. Arrange wiring and cables to
prevent obstructions when driving. Cables or wiring that obstruct or hang up on places such as steering wheel, brake
pedals, etc. can be extremely hazardous.
• DO NOT DAMAGE VEHICLE SYSTEMS OR WIRING WHEN DRILLING HOLES. When drilling holes in the chassis for
installation, take precautions so as not to contact, puncture or obstruct brake lines, fuel lines, fuel tanks, electrical
wiring, etc. Failure to take such precautions may result in fire or an accident.
• DO NOT UTILIZE OR CONNECT TO ANY PART OF VEHICLE SAFETY SYSTEMS. Bolts, nuts or wires used in the
brake, airbag, steering or any other safety-related systems or fuel tanks should NEVER be used for mounting, power or
ground connections. Using such parts may disable control of the vehicle or result in fire.
CAUTION
• STOP USE IMMEDIATELY IF A PROBLEM OCCURS. Failure to do so may result in personal injury or damage to the
product. Return it to your authorized Wāvtech dealer.
• HAVE AN EXPERT DO THE WIRING AND INSTALLATION. This unit requires special technical skill and experience for
wiring and installation. To insure safety and proper function, always contact the authorized dealer where you
purchased the product to have it done professionally.
• INSTALL THE UNIT SECURELY WITH SPECIFIED PARTS. Be sure to use only the included parts and specified
installation accessories (not included). Use of other than designated parts may damage this unit. Install the unit
securely so that it will not come loose during a collision or sudden jolt.
• ROUTE WIRING AWAY FROM SHARP EDGES AND MOVING PARTS. Arrange cables and wiring away from sharp or
pointed edges and avoid moving parts such as seat hinges or rails to prevent pinching or wear. Use loom protection
where appropriate and always use a grommet for any wiring routed through metal.
• NEVER RUN SYSTEM WIRING OUTSIDE OR UNDERNEATH THE VEHICLE. All wiring must be routed, secured and
protected inside the vehicle. Failure to do so may result in fire, injury or property damage.
• INSTALL THE UNIT IN A DRY AND VENTILATED LOCATION. Avoid mounting locations where the unit will likely be
exposed to high moisture or heat without adequate ventilation. Moisture penetration or heat buildup may result in
product failure.
• REDUCE GAIN AND SOURCE VOLUME TO MINIMUM LEVELS FOR INITIAL SYSTEM TUNING AND BEFORE
CONNECTION TO AN AMPLIFIER. Ensure amplifier power is off before connecting RCA cables and follow proper
system gain setting procedure. Failure to do so may result in damage to the amplifier and/or connected components.

ΠPower Indicator: This red LED indicates when the linkQ 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 200Ω 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 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 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 linkQ’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.
Clipping Indicator: This yellow LED indicates when the output signal is at maximum level before
distortion (clipping) occurs. It will be dimly lit just before the onset of clipping, and full bright at
clipping. Since the linkQ can produce up to 10Vrms output before clipping, it is likely that gain will
need to be reduced below the illumination point to match your amplifier(s) maximum input capability,
optimize source volume range or compensate for any equalization applied after initial gain setting.
‘ Gain Adjustment: This adjustment is for matching the output signal level of the linkQ with the
maximum unclipped signal range provided by your source and the maximum input capability of your
amplifier(s). Follow proper gain setting procedures to ensure optimum source volume range with
minimum chance for clipping at any point in the signal chain. Aside from music, a -10dBfs sine wave
tone at a frequency not affected by any crossovers may also be used for the tuning process to ensure
proper headroom and gain overlap for typical music recording levels.
’ Bass EQ: This section provides adjustments for a single paragraphic EQ band, which allows tuning
flexibility for differences between vehicles and sound systems to optimize bass performance.
“ Boost: Sets the amount of boost applied at the center frequency (Fc), adjustable up to +12dB.
” Frequency: Sets the center frequency (Fc) of the EQ band, adjustable from 30Hz to 80Hz.
• EQ On/Off: This switch activates or bypasses the internal equalization circuit (default setting is off).
