Wavtech Ultra-Compact 500W Monoblock Amplifier with OEM Integration

The link500.1mini amplifier was engineered from the ground up to be the best possible option for adding bass to any system. The speaker level input can handle up to 40V and features built-in loading, while the RCA input accepts up to 10V, making it the perfect solution for both factory and aftermarket head units. The link500.1mini produces 500 watts RMS @ 2ohms, and its incredibly small size means it will fit almost anywhere.

The link500.1mini utilizes Wāvtech’s proprietary bassFREQ preamp. It features a 24dB per octave crossover, adjustable parametric EQ and a subsonic filter, providing the fine tuning required to get the best out of any subwoofer. Like all Wāvtech amplifiers, the link500.1mini is compatible with start/stop systems. The optional linkRC remote provides for even more system control.

Amplifier switches/dials located on the top panel:

INPUT RANGE - 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 - 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

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.

FREQ - 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 - This adjustment sets the -3dB cut-off point 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 overexcursion below the tuning frequency.

LPF - 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
