AC Power Considerations

Ensure that the unit is plugged into an outlet capable of supplying the correct voltage and current specified for your model. Remember to account for the electrical power that other components will require if they share a common wall socket or electrical circuit. The majority of household electrical sockets in places other than the kitchen and garage are 15 amperes maximum. Most DVD players and other source components are fairly low current items. When all seven of the power modules are installed, the Emotiva MPS-1 requires a minimum of 15 amperes @ 120 volts or 8 amperes @ 230 volts. 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. DO NOT plug the MPS-1 into a power strip or extension cord unless the device is specifically designed and rated for high current use.

Refer to your preamplifier, A/V source component(s), and video display owner’s manuals to learn the power requirements so you can safely plan your electrical power requirements for your home entertainment system.

Input Connection Considerations

The MPS-1 contains both unbalanced RCA inputs and balanced XLR inputs. You must choose one or the other for each channel connected. You cannot use XLR cables in, with RCA out, or RCA in with XLR out. There is no direct internal connection between the RCA and XLR inputs.

Whenever possible, keep preamp level audio cables away from electrical power cords by at least a few inches. It’s more important with amplifiers as the AC power cords are carrying much more cur- rent than other source and preamplifier components, which means there is a larger degree of noise or “hum” potential with the amplifier power cord proximity.

Output Connection Considerations

The output connectors provided on each channel of the MPS-1 are standard“binding post”speaker connectors with industry standard spacing. These are sometimes called 5-way binding posts because of the many ways in which the speaker wire can connect into the posts. The posts can accept bare wire, spade terminals, and dual or single banana connectors. Spade connections or banana plugs ensure a simple, solid fit in the terminal whereas bare wire may be awkward when the terminal is screwed down to compress the wire into place. Keep in mind that if you use “dual banana” plugs and “stack” them, you will be creating a parallel connection. For more details on series and parallel connections, see pages 24-25.

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.
