Installation and Connections 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 curren

Input Connection Considerations 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 current than other source and preamplifier components, which means there is a larger degree of noise or “hum” potential with the amplifier power cord in close proximity. Output Connection Considerations The output connectors provided on each channel of the LPA-1 are standard

Connection Diagrams Connecting a 7.1 Preamp/Processor Connection using a 7 channel preout to LPA-1 For details on connecting the speakers to the 5 way binding posts, please see Page 18 When connecting the LPA-1 to drive a 7.1 system, you can use channels 1-5 for the “Main” speakers as you wish, but Emotiva recommends using channels 6 and 7 as the “Rear Back” surround channels so that the power is distributed correctly in the room. This will yield the best results from the front L/C/R speake

12V Trigger Connections The 12 VDC trigger connection shown can be used to turn the amplifier on when the preamplifier turns on. This trigger will actually trigger with any switched DC Voltage from 5-12 VDC, however the majority of home theater components use a standard 12 VDC trigger connection for this function. This is the preferred connection as it has the greatest degree of reliability. Never switch anything that plugs directly into the wall with this trigger connection. This actio

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. The connection of more than one

• The negative output terminal of the right channel connects to the negative input post of the fi rst speaker and and and to the negative post of the second speaker to the negative post of the second speaker.. The total impedance of equal speakers in parallel is found by dividing the impedance of one speaker by the number of speakers. For example, two eight ohm speakers in parallel is a four ohm load (eight ohms divided by two), four eight ohm speakers in parallel is a two ohm load (eight ohm
