Match UP Mono Amplifier

*Special Order* Owner's Manual

Power. Precision. Control: MATCH UP 1FX

Exceptionally compact and powerful, this highly efficient high-fidelity Class D amplifier delivers exceptional sound quality in combination with an impressive output power of up to 1000 Watts. The immense power drives even high-performance subwoofers to peak performance and makes the UP 1FX the perfect companion for all HELIX and MATCH subwoofer chassis and enclosure subs.

Perfect integration without compromises

Simple and uncompromising – the MATCH UP 1FX offers the ideal solution for upgrading factory subwoofer amplifiers, thanks to the integrated active crossover and high power stereo highlevel input with ADEP.3, max. 32 V input voltage, and signal summing. The mono RCA / Cinch input as well as the DirectDSP function make it the perfect complement to our MATCH UPGRADE DSP amplifiers. Furthermore, the power supply with Start-Stop capability and extended input voltage range of up to 18 V enables the amplifier to be used in modern electric vehicles.

Pure sound enjoyment

Despite its enormous output power, the MATCH UP 1FX is more than just a subwoofer amplifier. Its special construction, excellent signal-to-noise ratio, and low distortion guarantee pure audio enjoyment. Therefore, the UP 1FX is the perfect partner for heavy-duty mid-woofers in audiophile system concepts. In addition, the  innovative DirectDSP function allows bypassing the internal crossover and routes the input signal unfiltered to the output stages of the amplifier, delivering a sound that even exceeds the expectations of discerning music enthusiasts.

Compact dimensions for flexible installation possibilities

Contrary to its impressive power output, the 1-channel subwoofer upgrade amplifier comes in the same extremely compact dimensions as our UP 8DSP amplifier. This allows space-saving installations, even in vehicles with limited space.

  • The perfect companion for MATCH UPGRADE amplifiers thanks to mono RCA input

Special Features: 

Smart highlevel input ADEP.3

Modern, factory-installed car radios incorporate sophisticated possibilities of diagnosing the connected speakers. In particular the latest generation of car radios are equipped with additional monitoring functions so that failure messages and loss of specific features (e.g. fader function) quite often appear if a common amplifier will be hooked up – but not with the UP 1FX.
The new ADEP.3 circuit (Advanced Diagnostics Error Protection, 3rd Generation) avoids all these problems without loading the speaker outputs of the OE radio during high volumes unnecessarily.

Start-Stop capability

The switched power supply of the MATCH UP 1FX assures a constant internal supply voltage even if the battery’s voltage drops to 6 Volts during engine crank. If the supply voltage drops below 10.5 Volts for more than five seconds the amplifier goes to “Protect mode” (Status LED lights up red) in order to avoid any further discharge of the car’s battery.
