If no effect is being applied on your Yamaha MG124CX Music Mixer, first check that the EFFECT control on each channel is correctly adjusted. Next, make sure that the internal effect unit’s ON switch is turned ON. Finally, be sure that the EFFECT PARAMETER control and EFFECT RTN fader are correctly adjusted.
What to do if there is no sound from my Yamaha MG124C?
If you're not getting any sound from your Yamaha Music Mixer, make sure your microphones, external devices, and speakers are correctly connected. Also, verify that the ON and ST switches on the channels you're using are turned ON. Check if the channel GAIN controls, Channel fader, STEREO OUT master fader, and GROUP 1-2 fader are set to appropriate levels. Ensure the MONITOR and 2TR IN switches are properly set, and that your speaker cables are correctly connected and not shorted.
Why is the sound faint, distorted, or noisy on my Yamaha MG124C?
If the sound from your Yamaha Music Mixer is faint, distorted, or noisy, check that the channel GAIN controls, Channel fader, STEREO OUT master fader, and GROUP 1-2 fader are set to appropriate levels. Ensure that you haven't connected two different instruments to both the XLR-type and phone jacks, or to the phone and RCA pin jacks on one channel—use only one jack per channel. Verify the input signal from the connected device is at an appropriate level and that you're applying effects at an appropriate level. Also, make sure microphones are connected to the MIC input jacks on channels 1 to 7/8, and if you're using condenser microphones, confirm that the PHANTOM +48 V switch is turned ON.

The Yamaha MG124CX/MG124C mixing console is a versatile audio mixer designed for a wide range of usage environments, offering ease of operation and support for multiple input devices. The MG124CX model further enhances audio production with high-quality built-in digital effects.
The MG mixer is equipped with multiple input channels, supporting up to six mic/line inputs or four stereo inputs. This allows for simultaneous connection of various devices such as microphones, line-level devices, and stereo synthesizers.
Compression: A key feature of the mixer is its compression capability, which increases the overall audio level without introducing distortion. This is achieved by compressing excessive peaks in signals, particularly useful for microphones and guitars, resulting in a smoother, more unified sound. The MG compressor simplifies this process by allowing adjustment with a single control, automatically setting pertinent parameters.
AUX Sends and Stereo AUX Return: The mixer includes AUX SEND jacks, enabling users to route signals to external signal processors. The processed stereo signal can then be returned to the mixer via the RETURN jacks. This feature is useful for adding external effects or creating monitor mixes.
Digital Effects (MG124CX): The MG124CX model boasts high-quality built-in digital effects, offering a wide range of sound variations. These effects include various reverbs, delays, chorus, flanger, phaser, auto wah, and distortion. The effects can be applied to individual channels, similar to external effects processors.
Equalizer (EQ): Each channel features a three-band equalizer (HIGH, MID, and LOW) for adjusting frequency bands. Channels 1-8 have a three-band EQ, while stereo channels 9/10 and 11/12 have a two-band EQ (HIGH and LOW). The EQ controls allow for boosting or attenuating specific frequency ranges, enabling users to refine the sound of each instrument or vocal. The "7/80 Switch" (High Pass Filter) cuts frequencies below 80 Hz, which is useful for removing unwanted low-end rumble from microphones.
PAN/BAL Control: The PAN control (channels 1-4) determines the stereo positioning of a channel signal on the Group 1 and 2 buses or the Stereo L and R buses. The PAN/BAL control (channels 5/6 and 7/8) acts as a PAN control for mono inputs and a BAL control for stereo inputs. The BAL control (channels 9/10 and 11/12) sets the balance between left and right channels for stereo inputs.
ON and ST Switches: The ON switch sends the channel signal to the buses, indicated by an orange light. The ST switch assigns the channel's signal to the Stereo L and R buses.
PFL (Pre-Fader Listen) Switch: This switch allows monitoring of a channel's pre-fader signal through the PHONES and MONITOR OUT jacks, enabling accurate level adjustment before the signal reaches the main mix.
Channel Faders: These faders adjust the level of individual channel signals, used to create the desired balance among various channels in the mix.
Master Control Section:
Getting Sound to the Speakers: The Quick Guide outlines a step-by-step process for connecting speakers and generating stereo output. This includes ensuring all level controls are down, connecting input devices and speakers, powering up devices in the correct order (peripherals → mixer → power amps), adjusting GAIN controls for optimal input levels, turning on channel ON and ST switches, setting the STEREO OUT Master fader to "0," and finally adjusting channel faders for balance and overall volume.
Balanced vs. Unbalanced Lines: The manual emphasizes the importance of balanced lines for noise rejection, especially for long cable runs and microphone cables, due to their low output signal. Unbalanced lines are suitable for short connections in noise-free environments.
Signal Levels and the Decibel: The manual explains the concept of the decibel (dB) as a non-linear scale for audio measurements, highlighting the importance of matching input and output levels to optimize dynamic range and minimize noise.
To EQ or Not to EQ: The guide advises using EQ sparingly, particularly with boosting, to avoid muddying the mix. Cutting frequencies can help eliminate interference between instruments and improve overall sound definition. Examples include rolling off low EQ on cymbals and high EQ on kick drums to create space in the mix.
Ambience Effects (Reverb, Delay): The MG124CX's internal effects can add depth and space to mixes. The manual provides guidance on adjusting reverb and delay times based on music tempo and density, selecting appropriate reverb tones, and setting reverb levels to avoid over-processing.
Modulation Effects (Phasing, Chorus, Flanging): These effects work by time-shifting a portion of the audio signal and mixing it back with the direct signal, controlled by an LFO. Phasing creates shimmering sounds, while chorus and flanging thicken and create swirling or swishing sounds, respectively.
Connecting External Devices: The mixer supports connecting external devices via INSERT jacks (channels 1-4) for graphic equalizers, compressors, or noise filters. Special insert cables are required for this.
Monitoring: The PFL switches and MONITOR/PHONES section allow for precise monitoring of individual channel signals or the main mix, crucial for accurate level and balance adjustments.
Power Management: The manual stresses the importance of using only the supplied PA-20 adaptor to prevent equipment damage, overheating, or fire. It also advises unplugging the adaptor from the wall outlet when the mixer is not in use for extended periods or during lightning storms, as a trace current flows even in STANDBY mode.
Connection Best Practices: Users are instructed to turn off all devices before connecting cables and to set all volume levels to minimum before powering on or off to prevent speaker damage. When connecting electric guitars and basses, using an intermediary device like a direct box or preamp is recommended to avoid degraded sound and noise.
Phantom Power Safety: When using phantom power for condenser microphones, it is crucial to ensure only condenser mics are connected to XLR input jacks (CHs 1-7/8) and to turn off amplifiers or powered speakers before toggling the phantom power switch to prevent damage and loud noises. All output controls should be at minimum settings during this operation.
Environmental Considerations: The mixer should be protected from excessive dust, vibrations, extreme cold, or heat (direct sunlight, heaters, car interiors) to prevent panel disfiguration or damage to internal components. It should also be placed on a stable surface.
Troubleshooting Guide: The manual includes a comprehensive troubleshooting section to address common issues such as no power, no sound, faint/distorted/noisy sound, no effects (MG124CX), unclear spoken words, and issues with monitor output. This guide helps users identify and resolve problems by checking connections, control settings, and phantom power status.
Component Longevity: The manual notes that the performance of components with moving contacts (switches, volume controls, connectors) deteriorates over time and advises consulting qualified Yamaha service personnel for replacement of defective components.
