HOCK, E. AUTION: TO PREVENT ELECTRIC SHO CK, MATCH WIDE BLADE TTENTION: POUR EVITER LES CHOCS ELECTRIQUES, To prevent electric shock, do not use th is polarized plug with an extension cord, receptacle or other outlet unless the blades can be fully inserted to prevent blade exposure.
NEC (National Electrical Code) Standards his reminder is to call the CATV system installer’s attention to Article 82 0-40 of the NEC that provides ntenna Grounding Outside the House - If an outside antenna is connected to the receiver, be sure lways observe proper antenna or satellite dish grounding techniques.
Thank You for your UPA-7 Purchase Dear Home Entertainment Enthusiast, Thank you for purchasing the Emotiva UPA-7 Amplifier. We sincerely believe that it offers you outstanding performance and value. Emotiva products are engineered and produced with the hig hest quality materials and incorporate the latest technology .
Unpacking the UPA-7 The Emotiva UPA-7 Amplifier should reach you in flawless condition. If you notice any shipping damage or other issues upon unpacking the unit, please c ontact your Emotiva Retailer immediately. Inventory Included with your UPA-7 amplifier should be an IEC Class 1, 2 prong power cord, and this User’s Guide.
UPA-7 Front Panel Layout 1. Front Panel LED Display The front panel display contains Status LED lighting to indicate the condit ion of the UPA-7. • NO LED = Amplifier is OFF • BLUE LED = Normal Operation • FLASHING RED LED = Fault Condition - see “Troubleshooting” section for details.
UPA-7 Rear Panel Layout 1. RCA Audio Inputs - These inputs are for signal input on the UPA-7. Simply connect the appropriate input to your preamplifier/processor or other preamp level audio device. 2. Master Power Switch - This rocker switch provides the master power for the UPA-7.
Installation and Connections AC Power Considerations Ensure that the unit is plugged into an outlet capable of supp lying 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 .
Input Connection Considerations Whenever possible, keep preamplifier level audio cables away from electrical power cords by at least a few inches. It’s more important with amplifiers as the AC power.
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 th is function.
Connection Diagrams Connection using a 7 Channel Preamp/Processor 15.
Connection using a 7 Channel Preamp/Processor with Audio Devices and Speakers This configuration shows the UPA-7 driving full range chann els. This type of configuration is ideal for enthusiasts who have (or will) make their own self -powered subwoofer and want to utilize an amplifier that will drive the entire system in one chassis.
Series and Parallel Speaker Connections Series 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 w ill be impacted by adding the additional speaker(s).
Parallel Connections A parallel circuit is established when voice coils are connecte d in a way that there are multiple paths for audio signals to flow “in” and multiple paths for audio signals to flow “out”.
of different nominal impedances and/or different bandwidths are used, there are many other acoustic problems that come into play in addition to co mplex impedance at the amplifier’s speaker output terminals. If you must use multiple speakers on any individual amplifier channel, ple ase use speakers as close to identical as possible.
Troubleshooting Guide The Emotiva UPA-7 is expertly designed and built to provide years of trouble-free performance. Most problems that occur can usually be solved by che cking your setup or making sure that the audio and video components connected to the amplifier are on and fully operational.
• Make sure the amplifier has good ventilation and is not overheating. Allow good airflow underneath wherever possible. If the amplifier is in a closed rack, open up the rear panel or use a quiet fan for improved ventilation.
you will need a “ground loop isolator.” This is an inexpensive device fi tted in line with the coaxial cable feed. Contact your Cable Company or Emotiva for assistance. • Disconnect all connections from the preampli fi er to your TV, VCR or DVD.
Each RED light indicates a fault condition for the corresponding power module. A fault condition is one or more of the following: • Excessive Operating Temperature • Excessive Current (Short Circu.
