    MPS-1 Finished Rear Panel Layout Note: Before connecting any components to the MPS-1, the individual power modules must first be installed into the chassis. Please see pages 15-17 for details on the power module installation. Unbalanced RCA Inputs The MPS-1 has one unbalanced RCA input available for each amplifier channel mod- ule.

    Fuse #2 This fuse is also for the power supply of the MPS-1 chassis. It is a TL15AL type rated a 15A, 250 V. If the fuse ever fails, be sure to replace it with the same type and rated fuse.

  • Page 15: Installation And Connections

    Unpacking the EPM-300 Module You should have received your MPS-1 in a total of three boxes. The main MPS-1 chassis is in one of the boxes. The other boxes contain the EPM-300 power modules, one box with five modules and the other box with two modules.

  • Page 16: Orienting The Module To The Mps-1 Chassis

    Before inserting the power module, confirm that the 115/230 VAC voltage setting is correct for the country in which you are installing the MPS-1. These should be set correctly (by default) at the fac- tory at the time of testing and packaging.

  • Page 17: Inserting The Epm-300 Module

    (Top) Back power module into the MPS-1 chassis. Insertion of the power module is smooth and easy and it will not require any excessive force. If you must force the power module in, stop and re-evaluate your alignment of the nylon guide rails. Excessively forcing the power module can damage it. Use care not to damage the fan or electronic components during this installation.

  • Page 19: Ac Power Considerations

    It should be sufficient to allow the other devices such as preamplifiers and A/V source units to share a wall socket, but power amplifiers such as the MPS-1 and a video display (big screen TV or video projector) should be provided a SEPARATE electrical connection on a SEPARATE circuit. As the MPS-1 has a minimum requirement that consumes one entire circuit, please use a second (separate) electrical connection for other devices.

  • Page 20: Automatic Operation Of The Cooling Fan(S)

    Automatic Operation of the Cooling Fan(s) Each power module in the MPS-1 is equipped with a cooling fan to maintain a safe operating tem- perature. During normal operation the fan is off. The fan only becomes operational when it is required to cool the power module at temperatures in excess of 50 degrees Celsius (122 degrees Fahrenheit).

    This is the preferred method of activating the MPS-1. Alternatively, you could use the amplifier’s SIGNAL switch position. The amplifier will then automatically turn on when a preamp audio signal is received.

    This is the preferred method of activating the MPS-1. Alternatively, you could use the amplifier’s SIGNAL switch position. The amplifier will then automatically turn on when a preamp audio signal is received.

    VOID THE WARRANTY. If unable to use the trigger connection to activate the MPS-1, you could alternatively use the amplifier’s SIGNAL switch position. The amplifier will then au- tomatically turn on when a preamp audio signal is received.

  • Page 24: Series And Parallel Speaker Connections

    Series and Parallel Speaker Connections Whenever connecting more than one speaker per channel to an amplifier (regardless of the brand), you must consider the way in which the amplifier will be impacted by adding the additional speaker(s). Additionally, speakers with dual voice coils also apply to this consideration. Two voice coils in a single speaker also cause different reactions from an amplifier depending on the way in which they connect to the amplifier.

  • Page 25: Parallel

    Parallel A parallel circuit is established when voice coils are connected in a way that there are multiple paths for audio signals to flow “in” and multiple paths for audio signals to flow “out”. When speakers are connected in parallel, the total resistance at the amplifier is proportionally divided based on the value of each individual voice coil resistance.

  • Page 26: Speaker Placement Tips

    Ultimately, this will give a much better result when you are enjoying your home theater and your new Emotiva MPS-1. Overall, the best placement for front speakers is where the sound is directed at ear level. This means that the speakers themselves can be in positions lower (like small floor standing speakers) or higher (like in-wall or in-ceiling speakers) as long as the sound is “pointed”...

  • Page 27: The Front Speakers

    Place LEFT, CENTER, and RIGHT main speakers at equal distances from the listening position. If you have a smaller TV, the speakers should be no more than two feet away from the sides of the TV. If possible, have the center, left and right speakers at the same height (within two feet). This will help give a smooth transition when sound effects move from speaker to speaker.

  • Page 28: Side-Axis Speakers

    Potential Side Axis Speaker Locations them, place these speakers along the side walls, close to the fronts. You can also angle them in towards your listening position for better results. You should not use a surround or effect speaker (such as a dipole) for side axis speakers.

  • Page 29: Surround Back Speakers

    As such, it’s important to understand correct subwoofer placement so that you get the most out of the other speakers connected to the MPS-1 Modular Power Amplifier. A subwoofer typically sounds best in a corner with at least 5 feet of wall to either side.
  • Page 30 Play a test tone or low bass music Walk around the room and see Place the subwoofer where the bass has the best in the listening performance. That’s where your position subwoofer belongs! Notice where in the room the bass output from the subwoofer sounds the loudest. Shut things down and install the subwoofer there.

  • Page 31: Troubleshooting Guide

    Troubleshooting Guide The Emotiva MPS-1 is expertly designed and built to provide years of trouble-free performance. Most problems that occur can usually be solved by checking your setup or making sure that the audio and video components connected to the amplifier are on and fully operational.

  • Page 32: Turn-On And Turn-Off Thumps

    This problem is more than likely caused by a “ground loop” in your system, rather than a fault in the MPS-1. Follow these steps to isolate the main cause of the hum, there may even be more than one. Remember to turn off all components in your system, including the MPS-1, before disconnecting or connecting any cables.

  • Page 33: Other Probable Causes Of Noise

    Try connecting your system to another AC socket on a separate line. If the hum is heard from within the MPS-1 and not through the speakers, this may also be caused by interference on the AC or DC lines. The power transformers may turn this interference into an audible noise.
