Auto Turn-On Detect Jumpers:
By default, the ampliﬁer is set to detect both DC-oﬀset and audio signals for turning itself on/oﬀ automatically. These jumpers allow either turn-on mode to be defeated independently for cases where only one turn-on mode is preferred or to bypass both modes when a switched +12V trigger is available and connected to the remote turn-on (REM) terminal.
Load Jumpers: Each speaker level input channel has built-in loading to satisfy most OEM load detect systems. These internal loading circuits can be bypassed (OFF) for channels where no loading is required, such as when a speaker is still directly connected to the source.
Speaker Level Input Terminal: For left/right channels of speaker level input connections to the source. When set to the 20V input range (default), audio signal from 1-20Vrms will produce up to full power output from maximum to minimum gain. For factory amplifiers with more than 20Vrms output signal or if volume range is not sufficient with gains set at minimum, select the 40V input range, which will reduce the input sensitivity by half for signals up to 40Vrms.
RCA Input Bal/Unbal Jumpers: These jumpers select the RCA input configuration between balanced (default) and unbalanced. Unbalanced connects the RCA shield to ground reference,which may be useful in eliminating noise under certain source or system conditions. Both jumpers (left/right) should be moved together if changed.
RCA Inputs: For left/right channels of RCA line level input connections to the source. When set to the 5V input range, audio signal from 0.2-5Vrms will produce up to full power output from maximum to minimum gain. For sources with more than 5Vrms output signal or if volume range is not sufficient with gains at minimum, select the 10V input range, which will reduce the input sensitivity by half for signals up to 10Vrms. Use quality interconnects to ensure stable connection and minimize the possibility for induced noise.
Remote Level Control Jack: This RJ45 jack is for connecting the optional linkRC remote level controller to the main unit with its supplied cable. A standard ethernet cable may also be used.
Power/Protect Indicator: This LED will illuminate green when the amplifier is powered on and operating normally. If a shutdown occurs due to a detected fault, the LED will turn red. Note that over-current and short circuit protections require manual reset (power off/on) to recover after the fault has been cleared, while other protection modes will automatically recover.

Input Sensitivity Range: Two input sensitivity ranges are provided for each channel pair to optimize source volume range while minimizing the gain required to achieve full power output for best signal-to-noise. Choose the input range that will accommodate the source’s maximum output signal voltage without excessive clipping, 5V or 10V for low level (RCA) inputs, and 20V or 40V for speaker level inputs.
Gain Adjustment with Clip LED: This adjustment is for matching the amplifier’s input to the source’s maximum undistorted output signal. The clip LED will dimly illuminate just before the onset of clipping and become fully bright when the amplifier has reached full power output at clipping. Follow proper gain setting procedure to ensure optimum source volume range with minimum chance for clipping or distortion. Gain readjustment may be necessary after any changes made to the parametric EQ, subsonic or low-pass filters.
Parametric EQ: This section provides full adjustment over all parameters of a single EQ band,including boost, width and frequency. Unlike traditional bass boost, a parametric EQ provides the tuning flexibility required for differences between vehicles, subwoofers and enclosures.
Boost: This adjustment sets the amount of boost at the center frequency (Fc) of the parametric EQ band from 0dB up to +12dB. Note that adding boost may cause the output to clip or subwoofer to be over-driven. Readjust the gain, subsonic and low-pass filters as necessary to optimize bass response vs. maximum output and volume range.
Width: Also known as Q, width sets the bandwidth (BW) of boost for the parametric EQ band. A wide setting will include more adjacent frequencies for a broad boost, while a narrow setting will only boost frequencies close to the chosen center frequency (Fc). The range of Q adjustment is 1.5 (wide) to 5 (narrow). To calculate the bandwidth between the -3dB points that are boosted by the EQ band, use the formula BW = Fc/Q.
Example: If FREQ is set to 50Hz, and WIDTH is set to narrow (Q=5), then the boosted bandwidth is 50Hz/5=10Hz, which puts the upper and lower -3dB points at 45Hz and 55Hz.
Frequency: This adjustment sets the center frequency (Fc) of the parametric EQ band between 30Hz and 80Hz. Note that boosted frequencies that overlap with the subsonic and low-pass filters will attenuated.
Subsonic Filter: This adjustment sets the -3dB cut-off point (F3) below which all frequencies are filtered out at -24dB/oct. Very low frequencies can waste amplifier power and damage subwoofers. This adjustment is especially important for ported enclosures to prevent over-excursion below the tuning frequency.
Low-Pass Filter: This adjustment sets the -3dB cut-off point (F3) above which all frequencies are filtered out at -24dB/oct. Unwanted high frequencies allowed to play through subwoofers can cause boomy, buzzy bass that is easy to localize. With a steep -24dB per octave slope, the cut-off frequency can be set higher, allowing more punch with less distortion and optimized integration with full-range speakers to achieve up-front bass.

Note: If the subsonic and low-pass filter cut-off points are set too close together, only a narrow frequency range will pass through and may result in significantly reduced output.

Power Supply & Output Panel Connections

W vtech-lin k500.1mini-500W-RMS-Mono-Amplifier-5

Power Supply Terminal:
- Ground (GND): The ground terminal must be connected to a metal part of the vehicle with ground plane back to the main battery ground attachment point (a.k.a. chassis ground). This wire should be as short as possible,but no longer than 2ft (60cm),with minimum gauge of 8AWG.
  The ground wire should be terminated with a ground specific or ring terminal and securely bolted to the vehicle with a star or lock washer and nut to prevent from coming loose. The chassis ground connection point should be scuffed to the bare metal.
- Remote Turn-on (REM): If the source unit has a remote output wire (+12V switched output),connect it to the REM terminal. If a remote lead is unavailable, the amplifier will automatically turn-on by detecting DC-offset or audio signal from the source. While auto turn-on works well in most applications, there may be some cases were a +12V trigger is preferable or necessary.
  Both detect functions are enabled by default, but can be individually defeated via the two jumpers located on the input panel.
- Power (+12V): The constant +12V power connection must be made at the vehicle’s main battery, securely connected with a ring terminal and protected with an in-line fuse within 18in (45cm) from the positive battery terminal. The link500.1mini requires a 50A external in-line fuse (not included) and a minimum power wire gauge of 8AWG. Do not install the fuse until all other system connections have been made.
Speaker Output Terminal: This terminal is for connecting the amplifier’s output to one or more subwoofers as a single mono channel. The dual positive (+) and negative (-) outputs are provided for wiring convenience of parallel connections. Ensure correct polarity and that the connected subwoofer(s) are configured as a total nominal impedance no less than 2Ω.
Mounting Tabs: These mounting tabs are pre-attached and should be used to properly secure the amplifier with the included mounting screws to a solid mounting surface that is directly attached to the metal structure of the vehicle cabin. These tabs are removable if the unit can be safely secured by another method.

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 ensure years of enjoyment with your Wāvtech amplifier.

Note: Always connect stereo sources to both CH1(L) and CH2(R) inputs to retain full music content. If only one source channel is available, use an RCA y-adapter or jumper wires to connect it to both CH1 and CH2 inputs,otherwise signal level will be reduced by half and require increasing the gain to achieve full power output.

Notes:

Ensure at least a 2Ω minimum total load impedance for any single or multiple subwoofer system configuration.
After checking all wiring and connections, make all initial settings and adjustments before turning on the amplifier to avoid damaging the connected speakers. Gains should always start at minimum with the appropriate input range selected for your aftermarket or OEM source’s maximum output voltage. For smaller subwoofers, free-air or ported alignments, always set the subsonic filter cut-off frequency to protect them from being over-driven.
If bass output seems diminished vs. cone excursion, check the polarity of all input and output connections.
Depending upon the particular vehicle and subwoofer placement, reversing subwoofer polarity may be necessary to minimize cancellation of bass frequencies at the listening position.
