To Next PageTo Next PageWhat to do if no effect is applied on Yamaha MG166CX Music Mixer?
If no effect is being applied, first check that the EFFECT control on each channel is correctly adjusted. Then, ensure that the internal effect unit’s ON switch is turned ON. Finally, verify that the EFFECT PARAMETER control and EFFECT RTN fader are correctly adjusted.
What to do if there is no sound from Yamaha Music Mixer?
First, ensure that all microphones, external devices, and speakers are correctly connected. Next, verify that the ON and ST switches of the channels in use are activated. Check if the channel GAIN controls, Channel fader, STEREO OUT Master fader, and GROUP 1-2/3-4 fader are set to appropriate levels. Also, confirm that the MONITOR and 2TR IN switches are correctly set. Finally, inspect your speaker cables for proper connection and ensure they are not shorted. If the problem persists after these checks, further assistance may be needed.
Why is the sound faint, distorted, or noisy on my Yamaha Music Mixer?
The sound may be faint, distorted, or noisy if the channel GAIN controls, Channel fader, STEREO OUT Master fader, and GROUP 1-2/3-4 fader are not set to appropriate levels. Also, ensure that you are not connecting two different instruments to both the XLR-type and phone jacks, or to the phone and RCA pin jacks on a single channel; use only one jack per channel. Check that the input signal from the connected device is at an appropriate level and that you are applying effects at an appropriate level. If using condenser microphones, verify that the PHANTOM +48 V switch is turned ON.

The Yamaha MG206C, MG166CX, and MG166C are mixing consoles designed for a wide range of usage environments. These mixers combine ease of operation with support for various applications, with the MG166CX model featuring high-quality built-in digital effects for enhanced sound variations.
The MG mixers offer a comprehensive set of features for audio mixing and processing.
Input Channels: The MG206C provides up to 16 mic/line inputs and four stereo inputs, allowing for simultaneous connection of various devices such as microphones, line-level devices, and stereo synthesizers. The MG166CX and MG166C models offer 10 mic/line inputs and four stereo inputs. Each monaural input channel includes balanced XLR-type microphone input jacks (Pin 1: Ground; Pin 2: Hot; Pin 3: Cold) and balanced TRS phone-jack line inputs (Tip: Hot; Ring: Cold; Sleeve: Ground), which can also accommodate unbalanced phone plugs. Stereo channels feature unbalanced phone-jack stereo line inputs and unbalanced stereo RCA pin jacks. It's important to note that on channels with multiple input jack options, only one type of jack can be used at a time.
Insert Jacks: These TRS phone jacks (Tip = send/out; Ring = return/in; Sleeve = ground) allow for the insertion of external signal-processing devices between the equalizer and fader of the corresponding monaural input channel. This is ideal for connecting graphic equalizers, compressors, or noise filters. A special insert cable is required for this connection. The signal output from the INSERT jacks is reverse-phased, which is generally not an issue with effect units but should be considered for other devices to avoid phase conflict and potential sound degradation or cancellation.
Gain Control: The GAIN control adjusts the input signal level. For optimal signal-to-noise ratio and dynamic range, the gain should be set so that the PEAK indicator flashes only occasionally on the highest input transients. The adjustment range for MIC input is -60 to -16, and for LINE input, it's -34 to +10.
High-Pass Filter (HPF): The /80 switch toggles the HPF on or off. When activated, the HPF cuts frequencies below 80 Hz, helping to eliminate unwanted low-frequency noise. This filter does not apply to the line inputs of stereo input channels.
Compression (MG166CX/MG166C): The COMP control adjusts the amount of compression applied to the channel. Turning the knob to the right increases the compression ratio, while the output gain is automatically adjusted. This results in smoother, more even dynamics by attenuating louder signals and boosting the overall level. However, excessive compression should be avoided to prevent feedback.
Peak Indicator: The PEAK indicator lights red when the post-EQ signal level reaches 3 dB below clipping. For XLR-equipped stereo input channels, it detects both post-EQ and post-mic-amp peak levels.
Equalizer (HIGH, MID, LOW): This three-band equalizer adjusts the high, mid, and low frequency bands of the channel. Setting the knob to the center position provides a flat response. Turning the knob right boosts the band, while turning it left attenuates the band. Monaural channels have MID frequency controls to adjust the midrange frequency band, with a default of 2.5 kHz at the center position, adjustable from 250 Hz to 5 kHz.
AUX/EFFECT Control: These controls adjust the signal level sent to the AUX and EFFECT SEND jacks. The pre-fader send option is suitable for monitor systems, while the post-fader option is best for external signal processors. On the MG166CX, the Master SEND control (EFFECT) does not affect the level sent to the internal digital effect processor.
ON Switch: This switch turns the channel signal on or off, sending it to the faders and buses.
PFL (Pre-Fader Listen) Switch: This switch sends the channel's pre-fader signal to the PFL bus, allowing monitoring through headphones and the MONITOR OUT jacks.
Group Switches (1-2, 3-4): These switches assign the channel's signal to the GROUP 1/2 or GROUP 3/4 buses.
ST Switch: This switch assigns the channel's signal to the STEREO L/R bus.
Channel Fader: Adjusts the level of the channel signal. These faders should be set to minimum when not in use to reduce noise.
Digital Effects (MG166CX only): The MG166CX features 16 high-quality digital effects, including various reverbs, echoes, chorus, flanger, phaser, auto wah, and distortion.

Troubleshooting:
Component Deterioration: The performance of components with moving contacts (switches, volume controls, connectors) can deteriorate over time. Consult qualified Yamaha service personnel for replacing defective components.
Heat Generation: The MG mixer may heat up by as much as 15 to 20°C while powered on, which is normal. Panel temperature may exceed 50°C in ambient temperatures higher than 30°C, so use caution to prevent burns.
