Easy to install, easy to adjust - the MATCH DSP is the perfect solution for smaller sound systems, which are driven by the original car radio. Its layout not only allows classical configurations (front L/R, rear L/R + subwoofer) but also fully active front systems including subwoofer and center speaker. The versatile Aux input manages additional sources.

Nevertheless, the reduction to the basics is solely limited to the number of channels – the well-known PC software and the technology inside this stunning device is as perfect as every other product from Audiotec Fischer. 56 Bit signal processing, top-notch converters from Asahi Kasei and an uncompromising internal power supply care for outstanding measuring results and exceptional sound quality, both redefining the standards not only in this segment.

Power Save Mode

The Power Save Mode is incorporated in the basic setup. It allows to significantly reduce the power consumption of the amplifiers that are connected to the MATCH DSP once there's no input signal present for more than 60 seconds. Please note that in many up-to-date cars with "CAN" or any other internal bus structures it may happen that the radio remains "invisibly" turned on for up to 45 min. even after leaving the car! Once the "Power Save Mode" is active the remote output and therefore the connected amplifiers will be turned off. The MATCH DSP will reactivate the remote output within a second if a music signal is applied. It is possible to either modify the turn-off time of 60 sec. or completely deactivate the "Power Save Mode" via the DSP PC-Tool software. In basic configuration the "Power Save Mode" is always activated.

Start-Stop capability

The switched power supply of the MATCH DSP ensures a constant internal supply voltage even if the battery's voltage drops to 6 Volts during engine cranking.

The intelligent high level input

The 4-channel fully-differential high-level input is equipped with Audiotec Fischer's unique DEP circuit (Diagnosis Error Protection), which means that OE car radios with speaker diagnosis function will not generate any unwanted error logs if this DSP is connected.
