In this guide, we'll walk you through the steps to set up your RPA 5 amplifier, so you can get your sound system up and running smoothly.

What You’ll Need

• RPA 5 Power Amplifier
• Passive speakers
• Passive mixer
• XLR cables (2)
• SpeakON cables (2)
• Microphone
• Power cables

Step-by-Step Instructions

1. Connect Your Mixer to the Power Amp

• Using XLR Cables: To connect your mixer to the power amplifier, you'll need two XLR cables. Start by plugging the female ends of the XLR cables into the main left and right outputs of your mixer.
  • Take the other ends of the cables and plug them into the Channel A and Channel B XLR inputs on the back of the RPA 5 amplifier.
• Using Quarter-Inch Cables (Optional):The RPA 5 features combo jacks for XLR and quarter-inch inputs. You can also use quarter-inch cables to connect your mixer to the amplifier.

2. Connect the Power Amp to the Speakers

• Using SpeakON Cables: Next, you'll need two SpeakON cables. Plug one end of each cable into the Channel A and Channel B SpeakON outputs on the back of the RPA 5 amplifier.
  • Plug the other ends into the SpeakON inputs on the back of your passive speakers.

3. Adjust Volume Settings

• Ensure Proper Levels: Before powering anything on, make sure the master volumes on both the mixer and the amplifier are turned all the way down to prevent any unwanted noise or feedback.
• Turn On the Mixer and Amplifier: Power on your mixer first, then turn on the RPA 5 power amplifier.

4. Test the System

• Set the Mic Levels: Connect your microphone to any available channel on your mixer (e.g., Channel 1). Raise the gain for your microphone channel.
• Raise the Master Faders: To hear the sound through your speakers, raise the main left and right faders on your mixer.
• Adjust the Amplifier’s Volume: Now, adjust the volume knobs on both Channel A and Channel B on the amplifier to your desired levels.
• Microphone Test: Turn on your microphone, and you should hear your voice coming through the speakers.

5. Understand the LED Indicators

• Power Indicator: This light indicates that the amplifier is powered on.
• Signal Light: The signal light confirms that the amplifier is receiving input from the mixer.
• Clip Light: This light will turn on when the amplifier has reached its peak volume and begins to distort. If this happens, adjust the levels to prevent distortion.
• Fault Light: If there is an issue with the amplifier, the fault light will illuminate. Troubleshoot the problem as needed.

6. Additional Output Options

• Link Out XLR Outputs: The amplifier has Link Out XLR outputs for connecting to additional powered speakers or another power amplifier.
• RCA Input: You can connect your mixer to the amplifier via RCA cables if desired.

7. Adjust Frequency Response

• Switch Between Stereo and Bridge Mode: The RPA 5 has a “Bridge” mode option if you need to drive higher-powered speakers. Flip the switch on the back to "Bridge" for this setup. If you're using two speakers in a traditional stereo configuration, leave it in “Stereo” mode.
• Low-Pass Filter: If you want to focus on the low end frequencies, activate the low-pass filter by flipping the corresponding button on the amplifier’s back panel.

8. Connect Passive Speakers via Terminals

• Wire the Speakers Directly: If you prefer, you can use the positive and negative wire connections on the back of the amplifier to connect your passive speakers directly.
  • Unscrew the positive and negative terminals on the back of the amplifier, feed the speaker wires through, and tighten the terminals to secure the connection.

Conclusion

Setting up your RPA 5 2-Channel Power Amplifier is straightforward and offers a variety of connection options to suit your needs, whether you're running a live performance, DJ event, or studio setup. With proper wiring and volume adjustments, you'll be able to achieve clear and powerful sound through your passive speakers.
