RPM45: How To Set Up & Use

Introduction: In this guide, we'll walk you through how to set up and connect various audio sources to your RPM45 mixer. Whether you’re connecting microphones, instruments, speakers, or even a subwoofer, the RPM45 provides the flexibility you need for live performances or practices. Let's get started with a complete overview of the inputs, outputs, and controls on the mixer.

Requirements:

• RPM45 Mixer
• Powered speakers or subwoofer
• XLR cables (for microphones)
• 1/4" cable (for instruments)
• RCA to AUX cable (for music devices like tablets)

Step-by-Step Instructions:

1. Connecting Speakers to the Mixer

• Prepare the Speakers: For this example, we’re using SPGN 108 8-ohm speakers with Speakon inputs and outputs.
• Connect to the Mixer:
  • Plug the Speakon end of the cable into the Speakon input on the back of the speakers.
  • Plug the 1/4" end into the speaker output on the back of the RPM45 mixer.
• Speaker Considerations: Ensure your speakers are 8-ohm for optimal compatibility with the mixer.

2. Powering on the Mixer

• Plug in the power cable to the mixer and turn it on.

3. Connecting a Microphone

• Plug in the Microphone: Use an XLR cable and plug the female end into your microphone, then plug the other end into the XLR input of channel 1 (or any other channel).
• Adjust the Volume:
  • Raise the volume knob for channel 1.
  • Increase the master volume to hear the microphone through the speakers.
• Test the Microphone: Speak into the mic and check if you can hear your voice through the speakers.

4. Connecting an Instrument (e.g., Guitar)

• Plug in the Instrument: Use a 1/4" cable to connect the instrument (e.g., guitar) to the line input of any channel (channel 2 in this case).
• Adjust the Volume:
  • Raise the volume knob for channel 2.
  • Increase the instrument volume.
• Test the Instrument: Play your instrument to check the sound through the speakers.

5. Using Multiple Microphones and Instruments

• You can use up to four microphones or instruments. For multiple mics, repeat the steps for channels 2, 3, and 4.

6. Fine-Tuning with EQ

• Adjusting Treble:
  • The treble knob affects the high-end frequencies. Raise or lower it to change the clarity of your voice or instrument.
• Adjusting Bass:
  • The bass knob controls the low-end frequencies. Raise or lower it to add more body or reduce muddiness.
• EQ Testing: Test both knobs while speaking or playing to find the balance you want.

7. Using Reverb and Effects

• Reverb Control:
  • Use the Reverb knob on each channel to add reverb to the sound.
• Echo and Delay Effects:
  • Use the Echo and Delay knobs on the effects controller to adjust the presence and spacing of the reverb effect.
• External Effects:
  • You can connect external effects through the Effects Return on the back of the mixer. Use a Y-cable to plug in external effect devices.

8. Playing Music Through the Mixer

• USB Input: Plug a USB stick with music into the front USB input and use the MP3 Volume knob to adjust the music volume.
• RCA Input: Use an RCA to AUX cable to connect your tablet or another device to the mixer. Raise the CD/Tape Volume to hear the music.
• Test Music Playback: Play music from your tablet or USB stick and adjust the volume to your preference.

9. Connecting a Subwoofer

• Using Line Output: On the back of the mixer, use the Line Output to connect a powered subwoofer.
• Set Crossover and Volume:
  • Adjust the crossover and volume on the subwoofer to match the audio from the mixer.
• Test the Subwoofer: Play music from your tablet through the RCA input, and check if the subwoofer is outputting the low frequencies.

10. Recording Output

• The RCA Record Output on the back of the mixer allows you to send the signal to recording devices or other external systems.

Conclusion:

Setting up your RPM45 mixer is simple and versatile, whether you are using it for microphones, instruments, music playback, or subwoofer integration. The various controls, like EQ, reverb, and volume adjustments, allow you to fine-tune your setup for any performance or event.
