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!
- Class-D Power: Class D refers to the amplifier design, not quality. Class D provides incredibly efficient and clean power, perfect for a high power, small size amplifier like MP500. With up to 500 watts of power inside a chassis smaller than most disc players, MP500 brings the power without the bulk.
- DSP Presets: MartinLogan engineers created performance optimized DSP presets (for select MartinLogan CI/Outdoor speakers) ensuring you get incredible sound and reliability. MartinLogan custom subwoofer DSP presets also include an optional low pass filter option to help support your custom install.
- Keeping Cool: Featuring a robust, yet quiet, active cooling system to keep things under control even under extreme playback. With no user intervention required, the cooling system engages as needed to keep the air flowing and the components cool. Maximum reliability, minimal noise.
- Flexible Inputs: MP500 has Stereo RCA, Digital Coax, Digital Optical, and a dedicated Subwoofer (LFE) input offering plenty of flexibility to directly connect your favorite source or by connecting directly to the “Subwoofer Output” of your AVR or other electronic device.
- Power Density: When multiple amps are needed, an optional connector bracket is available to mount 2 units side by side in the same rack space. With a 1U height and half-rack width, MP500 makes efficient use of your valuable rack space allowing you to run up to 4 subwoofers in a single rack space!
- The Perfect Pairing: With outdoor audio becoming more popular, MP500 is the perfect match for the versatile MartinLogan Outdoor Living Foundation 8.1 system. With both a Stereo and Mono (All Channel Stereo) DSP preset, this perfect pairing makes it simple to bring HiFi sound to your outdoor paradise.

A: Hello. Thank you for your question and we hope all is well. Sound can be subjective, so it would be hard to say if you personally like it better than your Onkyo, but it does have more power than the Onkyo and should drive your speakers more efficiently. The MP500 is a power amp and you technically don't need a pre-amp, however, it would typically be paired with one because it doesn't have all the inputs a pre-amp would have and doesn't have a remote. If someone had preouts on their a/v receiver or pre-amp, they could use the MP500 with it. Your Onkyo unfortunately doesn't have preouts so you would need another preamp or a/v receiver to work with it. Note, it can still be used without one, but we just wanted to make sure you were aware of the limitations before considering it. We hope this helps and please let us know if there is anything else we can assist you with. Thanks again for your question and we appreciate your support.
A: Hello and thank you for your question. The amp will be sufficient for the speakers, but it does have some restrictions in other areas depending on your use case. Its purpose is to be a power amp. Note, there is no remote control and the volume knob acts as a limiter. We only want to mention this depending on your use case as it may not be the solution you are looking for. It will have sufficient power for the speakers though. We hope this helps and thank you for your interest and support.
