RPM1470 | RPM109: How To Replace The Fuse

Introduction:

This guide will walk you through the simple steps for connecting a microphone or instrument—like a guitar or keyboard—to your Rockville RPM1470 mixer. Whether you're setting up for a rehearsal or live performance, this article breaks down the process clearly and is beginner-friendly.

Requirements:

• Rockville RPM1470 mixer
• Dynamic or condenser microphone (with XLR cable)
• Instrument (guitar, keyboard, etc.)
• 1/4" instrument cable
• Speakers connected to the mixer

Step-by-Step Instructions

1. Understanding Your Mixer Inputs

• The RPM1470 has 14 total channels
  • Channels 1–12: Combo inputs (XLR + 1/4” line level)
  • Channels 13–14: Used for built-in MP3 playback

2. Connecting a Microphone (Dynamic or Condenser)

For Dynamic Microphones:

1. Plug the female end of your XLR cable into the microphone.
2. Plug the male end into one of the XLR inputs on the mixer (e.g., Channel 1).
3. Turn up the Gain knob at the top of the channel strip to set the input level.
4. Raise the Channel Fader for that channel to set the output.
5. Raise the Main Left and Right Faders so the signal comes through your speakers.
6. Speak into the mic to confirm it's working.

For Condenser Microphones:

• Follow the same steps as above.
• Important: Press the Phantom Power button to supply power to the mic.

3. Connecting an Instrument (Guitar, Keyboard, etc.)

1. Use a 1/4" instrument cable.
2. Plug one end into your instrument (guitar, keyboard, etc.).
3. Plug the other end into the Line Input of any available channel (e.g., Channel 2).
4. Turn up the Gain knob to adjust the input level.
5. Raise the Channel Fader for that input.
6. Ensure the Main Left and Right Faders are raised so the signal plays through the speakers.
7. Start playing your instrument to verify sound output.

Note: You can use the same channel for both mic and instrument, but using separate channels allows better control.

4. Using Both Mic and Instrument Together

• Connect your microphone to Channel 1.
• Connect your instrument to Channel 2.
• Adjust each Gain and Fader accordingly.
• Raise the main faders to hear both sources through your speakers simultaneously.

Troubleshooting & FAQs

Q: My microphone isn't producing sound. What should I check?

• Ensure the Gain and Channel Fader are turned up.
• Confirm the Main L/R Faders are also raised.
• If using a condenser mic, make sure Phantom Power is turned on.

Q: I can’t hear my guitar through the mixer.

• Make sure the instrument cable is firmly connected.
• Try a different channel to rule out input issues.
• Check that the instrument’s volume knob is turned up.

Q: Can I use both XLR and line inputs on the same channel?

• Yes, but only one input type at a time per channel will be active.
