Automatic Operation Of The Cooling Fan(S); Connection Tips For Superior Sound - Emotiva MPS-1 User Manual

It is important to observe polarity so that the speaker wire connects to the red and black terminals
on the amplifer and the corresponding terminals at the speaker. Also make sure that the positive
speaker wires do not touch the negative speaker wires, or any chassis metal. This will cause a short
circuit and activate the protection circuitry.

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).
The speed of the fan will increase as the temperature increases. The fan will turn off when the power
module cools to 30 degrees Celsius (86 degrees Fahrenheit).

Connection Tips for Superior Sound

Before setting up your new system, please consider the following:
• Always make sure the MPS-1 is turned off before making or changing ANY connections.
• Whenever possible, route the power cords away from the signal cables or speaker wires to prevent
any hum or interference heard in the speakers.
• Many RCA type patch cords can be a very tight fit and there is usually a preferred method of get-
ting them off. Some have to be removed with a twisting action. Be gentle or you may damage the
jacks of your MPS-1, the cables themselves, or other components.
• Many audiophile signal cables are intended to be hooked up in one direction. If this is the case the
cables will be marked with arrows the direction of signal flow.
• It is usual for the right channel RCA patch cord plugs to be red and the left channel connections
to be white, grey, or black (depending on the cable brand). RCA connectors that are gold will be
designated with a colored band to designate the channel.
• If the preamplifier to which you will connect the MPS-1 features balanced XLR outputs, use the
MPS-1's balanced XLR inputs instead of RCA type patch cords. Balanced signal transmission be-
tween audio components provides superior rejection of hum and noise, especially if long cables
are required.
