The MP4000 uses class H topology to work hard, supplying high power output, and awesome fast reaction low-end response. For over a decade the Wharfedale Pro MP series amplifiers have long been revered for their workhorse like capabilities and extreme headroom levels. The MP4000 is no exception and as the big brother in the MP line-up this is the amplifier for those who require relentless and reliable power.

With a high slew rate across the MP Series, each amp reacts quickly to drive your loudspeakers as clearly and accurately as possible. Newly developed FRT or ‘fast reaction technology’ in the ‘s’ models create an even faster low frequency response assuring the MP2800s does not miss a beat during performance.

The MP2800s will work efficiently in stereo and bridge modes. The amplifiers also run down to 2 Ohms safely in stereo mode (1400W per channel) which means that the amplifiers can be used for a multitude of setups. Use in bridge mode with an individual high-powered subwoofer or use a single MP2800s to power multiple speakers equally.

The MP Series offers complete protection for your valuable PA equipment. Sophisticated protection circuitry includes soft start protection relay, thermal overload protection, short circuit protection and open circuit protection. The displays also keep the sound engineer well informed before with peak and protect LEDs. The high performance beasts that make up the MP Series are ready to exceed expectations in the most demanding live sound and installation environments. Whilst the amplifiers meet our stringent quality control factors we are also pleased to offer these high power amplifiers at a competitive industry-leading price point.
