  1. Input Channel Equalizers (Ch1-10): 3-band EQs on each channel that adjust high, mid and low frequencies. 
    • High: 12KHz ±15dB
    • Mid: 2.5KHz ±15dB
    • Bass: 80Hz ±15dB
  2. Channel Monitor Out Level (Ch1-10): Controls the amount of signal for that channel sent to the MONITOR bus. 
    Please note: This is a pre-fader, post-EQ output. The only things that affect the signal output to the MONITOR bus are High/Mid/Low Channel EQ controls and the Pad button. Anything else in the channel path does not affect this signal, including the 7-band EQ.
  3. Channel FX Level (Ch1-12): Controls the amount of signal for that channel sent to the built-in DSP effects (or to the FX send output if in use). 
    Please note: This is a pre-fader, post-EQ output. The only things that affect this FX signal output are High/Mid/Low Channel EQ controls and the Pad button. Anything else in the channel path does not affect this signal, including the 7-band EQ.
  4. L/R Pan (Ch1-12): Determines the position of the channel signal within the stereo image. It features a constant-power characteristic, which means the signal is always maintained at a constant level, irrespective of position in the stereo panorama.
  5. Level (Ch1-12): Controls the volume output (or "fader" level) per individual channel.
  6. Clip LED (Ch1-6): Indicates that the input signal is too high and distorting.
  7. PAD Buttons (Ch1-6): Attenuates the input signal by -20dB. Use this feature when connecting a line level device or if the Mic input is hot/distorted even with mini.
  8. 1/4" Balanced TRS Line Inputs (Ch1-6): This input may be used as either a high-impedance microphone input or for line-level devices such as a keyboard, cassette player, CD player, video projector or laptop. 
    • It may also allow connection from an electric guitar or bass. 
    • It is a three-conductor input with an impedance of 10K ohms.
  9. XLR Mic Input (Ch1-10): Connect microphones using balanced XLR audio cable (mic cable).
    • Input Impedance of 1K ohms
    • PIN 1 = Shield / Ground
    • PIN 2 = Positive (+hot)
    • PIN 3 = Negative (-cold)
      WARNING: When using condenser microphones, make sure that Phantom Power (item 12) is on.
  10. Stereo Channel Inputs (Ch7/8 & 9/10): These are stereo L/R 1/4" unbalanced (TS) inputs featuring a balanced XLR input. 
    • Please note: When the Left 1/4" jack is used alone, or the XLR input is used, the signal input is mono, meaning the signal plays in both the left and right channels.
  11. AUX/BT/USB/SD Button: Allows you to select between the AUX input and the MP3 module (BT, USB, and SD).
  12. Phantom Power Button (red LED indicates power on): When activated, this allows condenser microphones to function, while not affecting dynamic microphones. Please advise certain (ribbon) microphones can be damaged if used with phantom power.
    ⚠️Never unplug or plug in microphones while phantom power is on. It can cause severe damage to the mic. When phantom power is turned off, it is recommended you wait approximately 7 seconds so as to allow time for the voltage to completely dissipate.
  13. L/R RCA AUX In & Out (Ch11/12): These are stereo RCA inputs and outputs.
    • Aux Inputs: For connecting an MP3 player, laptop or any other device with a line level output. 
    • Aux Outputs: The outputs allow you to send the signal to a recorder (-10dB output level), or any other line level L/R device.

  18. MONITOR LEVEL: Controls the level/amount of the overall signal being sent from ch 1-10 from the monitor knob to each channel together. This can be used to send signal to stage monitors.
  19. MAIN OUT: These L/R 1/4" TS jacks provide unbalanced output. Its the line level of the main mix which can be sent to other devices.
  20. FX SEND: Sends a stereo line level signal to an external effects processor. This signal can be returned on any of the mixer's other line inputs on an unused channel.
  21. SD/USB Inputs: Accepts standard windows (FAT or FAT32) formatted* 32GB or less SD Cards / USB Thumb Drives.
    *The RPM109 V2 will not recognize drives formatted in the NTFS format; only the FAT or FAT32 formats.
  22. MAIN RIGHT Graphic EQ: 7 band equalizer allows you to adjust the frequency response (±12dB) of the right mains' signal.
  23. MAIN CHANNEL OUTPUT: Controls the overall output to the Main Output (front jacks) and Power Output (rear speaker outputs).
  24. Output Level Indicator: This peak level meter is made up of 20 LEDs (10 for the each cannel) with 3 colors to indicate the different ranges of signal level. You want your average level to be at 0dB for optimal output and sound clarity.

Troubleshooting

Problem

Solution

No power

  • Make sure the unit is plugged in and the power switch is in the ON position.
  • Check that the power cable is plugged in tightly to the unit.
  • Check and replace the fuse if necessary. See fuse replacement diagram on the next page.

No sound

  • Check that all appropriate cables are plugged in correctly.
  • Check the Main Channel Output settings.
  • Check the individual level control of each channel. Make sure the Ch1-10 mute switch is not pressed.
  • Make sure you've selected the right input input source (AUX/BT/USB/SD) for the appropriate channel.
  • Make sure your microphone is on. If using a condenser mic, make sure phantom power is on.

Noise

  • Turn down the channel levels one by one. If you don't hear the sound, then the problem is either with the channel or whatever device is plugged into it.
  • Unplug the device(s) to see if the sound disappears.
  • Make sure you are using the proper cables. For 1/4" cables, there are 3 types: speaker, TS line/instrument (unbalanced), and TRS line (balanced). Check the requirements of the connected gear and make sure you are using the appropriate cable.
  • Check EQ settings. Boosting EQ can potentially lead to distortion at a much earlier point or may sound too loud or harsh. To alleviate that, lower your EQ settings.

Buzzing sound

  • Make sure you are using a proper cable and that it is plugged in completely. 
  • For 1/4" cables, there are 3 types: instrument, TS (unbalanced), and TRS (balanced). Check the requirements of the connected gear and make sure you are using the appropriate cable.

Bad Channel

  • Check that the EQ is set up properly.
  • Check channel level.
  • Check that the channel pan is set to the 12 o'clock position.
  • Try setting up the same source signal on a different channel. Make sure to use the same settings as the suspect channel.
  • If using a microphone, make sure that it does not require phantom power.

Bad Output

  • Make sure the main level is turned up.
  • Check that the EQ is set up properly.
  • Unplug devices from other line level outputs just in case one of the devices has a problem.

Bluetooth Pairing Fails

  • Check to see that both devices are turned on and that your Bluetooth device is discoverable.
  • Turn both devices off and then on again.
  • Make sure you've selected the proper source. Check that the AUX-USB/SD/BT selector button is pressed.
  • Make sure that the Bluetooth device is within 5 feet of the unit.
  • Move both devices away from other Bluetooth devices, microwaves, wireless routers, and other electronics.
  • Make sure that all volume controls are set properly (Main Channel volume control as well as Ch11/12 volume control).
  • Make sure that the unit is not paired to a previously paired device.

No USB playback

  • Make sure your SD card or USB flash drive is not damaged.
  • Make sure the SD card or USB drive is formatted as FAT or FAT32. Cards and drives formatted as NTFS are not recognized.
  • Check that the files on the media device are not corrupt.
  • Make sure the files are properly formatted (WAV, MP3, WMA).
