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.
