4Turn On Selector Switch

This switch allows you to select how the amplifier will turn on and off.

In the ON (Up) position, the switch on the front of the amplifier is the method you will use to power up and power down the amplifier. Please note that in this configu- ration, you must manually power up and power down the amplifier each time you use it or it will have unnecessary standby current draw.

In the SIGNAL (Middle) position, the am- plifier automatically turns on whenever it senses an audio signal on any one of the seven amplifier channels. The circuit stays active for a full minute after the absence of any audio signal to account for quiet pas- sages of music or dialogue.

In the TRIGGER (Down) position, the ampli- fier’s ON and OFF functions are controlled by a trigger from a source or preamplifier device. The trigger accepts 12 VDC and will turn the amplifier on whenever a trigger is present (See #5). When there is no trigger, the amplifier goes into standby mode. This is the preferred method for activating the MPS-1.

5External Trigger Connection

This external trigger connection allows the amplifier to be turned ON and OFF by a control device such as a source unit or preamplifier. It can also be used with most home automation controllers. The trigger requires a 12 VDC trigger. This is the pre- ferred method of activating the MPS-1. See page 23 for connection details.

Fuse #1

This fuse is 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.

7Fuse #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.

8IEC Line Cord Socket

The MPS-1 comes with a detachable line cord which connects here. Plug the line cord into an AC wall socket which is cor- rectly configured with the voltage and current supply specified for the MPS-1. Do not plug this line cord into a power strip, it must plug directly into a wall socket. For more details on AC power considerations, see page 19.

MPS-1 specifications

The Emotiva MPS-1 is a powerful and versatile multi-channel amplifier designed to enhance audio performance in both home theaters and high-fidelity music systems. Known for its robust construction and high-quality sound output, the MPS-1 stands out as an ideal choice for audiophiles and home theater enthusiasts alike.

One of the defining features of the MPS-1 is its impressive power output. The amplifier delivers 200 watts per channel into 8 ohms and 300 watts into 4 ohms, providing ample headroom to drive even the most demanding speakers. This high power output ensures that users can enjoy dynamic sound without compromising on clarity or detail, making it suitable for both movies and music.

The MPS-1 utilizes advanced Class AB amplification technology, combining the efficiency of Class A with the thermal performance of Class B. This design minimizes distortion and maximizes linearity, ensuring that the sound remains clean and accurate across a wide frequency range. The amplifier also features a high-current output stage, allowing it to handle sudden peaks in audio without clipping, an essential quality for impactful sound reproduction.

Another significant aspect of the MPS-1 is its comprehensive connectivity options. It is equipped with both balanced XLR and unbalanced RCA inputs, providing flexibility for integration into various audio setups. The amplifier can also be configured to operate in a bridged mode, effectively doubling the output power to drive larger speaker setups or subwoofers, which enhances its versatility in custom installations.

In terms of build quality, the MPS-1 showcases Emotiva's commitment to durability. The amplifier features a heavy-duty steel chassis designed to minimize interference from external sources, while the high-quality components used in its construction—such as powerful power supplies and premium capacitors—ensure longevity and reliability.

The MPS-1 also incorporates intelligent thermal management features, including heat sinks and a built-in fan that operates only when necessary, keeping the unit cool during extended use without introducing unwanted noise.

Overall, the Emotiva MPS-1 represents a compelling choice for those seeking a high-performance multi-channel amplifier that combines power, flexibility, and exceptional audio fidelity, making it a worthy addition to any serious sound system.
