NEC (National Electrical Code) Standards A Note for the Cable Television (CATV) Installer This reminder is to call the CATV system installer’s attention to Article 820-40 of the NEC that provides guidelines for proper grounding and in particular, specifies that the cable ground shall be connected to the grounding system of the building as close to the point of cable entry as practical. -
Page 7: Thank You For Your Rpa-1 Purchase
The Emotiva RPA-1 is unlike any two channel home audio amplifier on the market. It has been designed with the user in mind. By employing technology that makes sense yet with a clear focus on the priority of superb sound reproduction, the Emotiva RPA-1 allows you to spend more time enjoying your music. -
Page 8: Unpacking The Rpa-1
Gently lift out the unit and remove all the packing material and accessories. It is important to save all the packing materials and the box in case your Emotiva RPA-1 ever needs to be moved or shipped back to the factory for service. -

XLR Audio Inputs These XLR inputs also provide the signal information for the left and right channels of the RPA-1 and are the preferred method of input signal connection whenever possible. Simply connect them to the appropriate output of the preamplifier or other preamp level audio device that has XLR outputs. -
Page 11: Installation And Connections
Upon powering up the RPA-1 with the front panel switch or via trigger input (switch on the rear panel must be set to “ON”), you will notice the front panel center LED status light illuminates blue. This indicates the amplifier is on, functioning normally, and ready for operation. -
Page 12: Input Connection Considerations
• Many RCA type patch cords can be a very tight fit and there is usually a preferred method of getting them off. Some have to be removed with a twisting action. Be gentle or you may damage the jacks of your RPA-1, the cables themselves, or other components. -

Connection Diagrams Connecting a Preamp Connection of a Preamp Level Device using XLR Inputs This diagram shows the RPA-1 amplifier connected to a preamplifier with XLR outputs. This is the preferred method of connection where possible. Connection of a Preamp Level Device using RCA Inputs This diagram shows the RPA-1 amplifier connected to a preamplifier with RCA outputs. -
Page 14: Connecting Speakers
Connecting Speakers Connection of a Stereo Speakers This diagram shows a traditional single connection to two loudspeakers, one left channel and one right channel. Internally the speakers have passive networks so there is just a single speaker connection. In this case, if there were multiple input terminals and you intend to drive each speaker with a single amplifier channel, you must make sure the shorting bars are in place on the speaker joining each positive to positive and negative to negative. -
Page 15: Biamped Connections (Low Pass And High Pass)
Biamped Connections (Low Pass and High Pass) This connection shows two RPA-1 amplifiers used in a bi-amp mode. One of the amplifiers is connected to the low frequency drivers and has a low pass filter employed by the preamplifier. The other amplifier has a high pass filter employed and is connected to the mid and high frequency drivers. -

The bottom post of each pair is the negative, and connects to the negative (black) post of your speaker. Regardless of the speaker configuration used for the RPA-1 amplifier channels, proper connection of each speaker is essential. The 5-way binding posts can accept bare wire, spade terminals, and dual or single banana connectors. -
Page 17: Series And Parallel Speaker Connections
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. -
Page 18: Technical Note About Multiple Speaker Connections
(eight ohms divided by four). Two ohm single channel loads are NOT RECOMMENDED for the RPA-1! Running the RPA-1 below recommended impedance level can cause excessive heat and will eventually drive the amplifier into protection (blinking red LED on the front of the unit). -
Page 19: Speaker Placement Tips
Ultimately, this will give a much better result when you are enjoying your home theater and your new Emotiva RSP-1. Overall, the best placement for front speakers is where the sound is directed at ear level. This means that the speakers themselves can be in positions lower (like small floor standing speakers) or higher (like in-wall or in-ceiling speakers) as long as the sound is “pointed”... -
Page 20: The Front Speakers
The Front Speakers You should closely follow the placement recommendations of your speaker manufacturer, with the addition of the following points: • The left and right front speakers should be positioned so that your TV is exactly centered between them. This will help create a stable phantom center image •... - Page 21 Place the subwoofer in Play a test tone or low the listening position bass music Walk around the room and see where the bass has the best performance. That’s where your subwoofer belongs! Notice where in the room the bass output from the subwoofer sounds the loudest. Shut things down and install the subwoofer there.

• If the preamplifier has a HPF, make sure that it has been correctly set. If you are not using a subwoofer, set the high pass filter to “BYPASS” (if available) or just use full range outputs into RPA-1 so that there is no path through a crossover and the speakers will play full range. -
Page 23: Turn-On And Turn-Off Thumps
• If your powered subwoofer is the cause of the “thump” sound (not the other speakers connected to RPA-1), plug it into a different 110VAC outlet than the RPA-1 amplifier so there is no power surge conflict. -
Page 24: Other Probable Causes Of Noise
• Try connecting your system to another AC socket on a separate line. • If the hum is heard from within the RPA-1 and not through the speakers, this may also be caused by interference on the AC or DC lines. The power transformers may turn this interference into an audible noise. Internal hum can be made worse by a shelf or cabinet resonating, so try moving the RPA-1 to another shelf. -
