RPM1870: How To Set Up Mic, Line Or Instrument

Introduction

The Rockville RPM 1870 is a versatile powered mixer that supports microphones, instruments, and line-level signals for live performances, band practice, and studio setups. This guide will walk you through connecting microphones, instruments, and line-level sources, along with setting gain, faders, and phantom power for condenser mics.

Step-by-Step Instructions

1. Connecting a Microphone

To connect a dynamic or condenser microphone:

1. Take an XLR cable and microphone.
2. Plug the female end of the XLR cable into the microphone.
3. Plug the other end into an available XLR mic input (e.g., Channel 1).
4. Set the Gain Knob for Channel 1 to about halfway to start.
5. Raise the Channel 1 Fader to adjust microphone volume.
6. Increase the Main Left & Right Faders to hear sound through the speakers.
7. Test the mic by speaking: "Check one, two"—your voice should come through the speakers.

💡 Using a Condenser Microphone?

• Press the Phantom Power Button (located on the side of the mixer) to provide 48V power.

2. Connecting an Instrument (Bass, Guitar, Keyboard, etc.)

To connect an electric bass, guitar, or keyboard:

1. Grab a ¼-inch instrument cable.
2. Plug one end into the instrument.
3. Plug the other end into the ¼-inch Line Input (e.g., Channel 2).
4. Raise the Gain Knob for Channel 2.
5. Adjust the Channel 2 Fader to set the instrument volume.
6. Ensure the Main Left & Right Faders are raised to hear the instrument.
7. Test your instrument by playing a few notes through the speakers.

💡 Tip: You can play an instrument and sing at the same time using separate channels for more control over each input.

3. Connecting a Line-Level Signal (Keyboard, Audio Player, etc.)

To connect a keyboard, drum machine, or external audio source:

1. Use a ¼-inch line-level cable.
2. Plug one end into the line output of the external device.
3. Plug the other end into an available line input on the mixer.
4. Raise the Gain Knob and Channel Fader for the input channel.
5. Ensure the Main Left & Right Faders are up for proper audio output.

💡 Tip: Use Channels 17 & 18 for stereo sources like keyboards or audio players.
