The MP500 is a 2-channel, Multi-Purpose, DSP amplifier with up to 500 watts of power on tap. In 2-channel mode it outputs 125w x 2 @ 8 ohms or 225w x 2 @ 4 ohms and when in bridged mode it can output up to 500w x 1 @ 8 ohms. While MP500 can be used to power nearly any speaker, the selectable onboard DSP presets focus on optimizing all MartinLogan Outdoor products, such as the MartinLogan Outdoor Foundation System, and Custom Installation subwoofers. MartinLogan engineers also went the extra step to make sure that the MP500 could even drive dual subwoofers! The following MartinLogan subwoofers are supported by the MP500’s “Dual Subwoofer” DSP presets to ensure powerful and reliable operation: Dynamo IW-S, Dynamo IW-O (with or without Back Box), Outdoor Living Subwoofer 8. With this and many other features, the MP500 is one of the most versatile custom installation amplifiers on the market!

When ordering the ML Outdoor Living speaker system I strongly recommend considering the Crown CDi amp. If you do order this amp from BB it will come preloaded with EQ configs specific to the ML Outdoor Living series so you can run your ML Outdoor Living Sats in either 8ohm, 70w or 100w depending on the size of your outdoor space. The first channel is dedicated to the 8ohm subwoofer which I believe you can hook up to 4 subs to this single channel (please verify in crown instructions before taking my word on this) The second channel is configurable for the satellite speakers. If you are new to this level of amplifier, do not be intimidated. a little bit of research and following the well written instructions can get you up and running without any issues. This does come with a Ysum RCA cable to combine L/R Stereo into a single output for each speaker. I did end up getting a second Ysum cable with a longer reach coming from my preamp but it is not necessary. If you have any questions about how the Amp works the ML customer service is extremely helpful so make sure to reach out if you have any concerns.
