Thank you for your purchase of the Yamaha MGP16X or MGP12X mixing console. Please read this manual thoroughly to make the best use of the mixing console for the longest possible period of time. After reading this manual, please keep it available for future reference.
Main Features Contents Sophisticated analog circuits D-PRE (Discrete Class-A MIC preamp) Main Features ................................ 3 Mono input channels are equipped with Class-A discrete microphone preamplifiers. The head amplifier features an inverted Darlington circuit* used in high-end audio devices, and reproduces low frequencies with exceptionally musical characteristics as well as sustained high frequencies. Independent toggle switching of +48V phantom power and 26dB (pad) on each channel.
PRECAUTIONS PLEASE READ CAREFULLY BEFORE PROCEEDING * Please keep this manual in a safe place for future reference. WARNING Always follow the basic precautions listed below to avoid the possibility of serious injury or even death from electrical shock, short-circuiting, damages, fire or other hazards.
Maintenance Yamaha cannot be held responsible for damage caused by improper use or modifications to the device, or data that is lost or destroyed. • Remove the power plug from the AC outlet when cleaning the device. Handling caution Always turn the power off when the device is not in use. • Do not insert your fingers or hands in any gaps or openings on the device (vents, ports, etc.). • Avoid inserting or dropping foreign objects (paper, plastic, metal, etc.
Making the Most of Your Mixer Balanced Cables and Unbalanced Cables Two types of cables can be used to connect microphones, electronic instruments, and other audio sources to the mixer’s inputs, as well as to connect the mixer’s outputs to a power amplifier or related gear: balanced or unbalanced. Balanced cables are highly resistant to noise, and are the best choice for low-level signals such as the output from microphones, as well as for long cable runs.
Making the Most of Your Mixer Level Adjustment for Optimum Mix Equalizer Tips The best advice that can be given regarding equalization while recording is simply to use as little equalization as possible. If you want a little more presence you can turn the HIGH end up a bit. Or you can boost the bass a little if you feel the low end is lacking. During recording it’s better to use EQ sparingly for compensation only.
Setup Setup Examples 1.
Setup 2.
Setup Rack Mounting The unit requires at least 11U* of rack space. To take into account the cable connections, we recommend to ensure at least 13U* of rack space. Mounting the MGP16X/MGP12X 1. Two metal rack-mount brackets are screwed onto the unit. Use a screwdriver to remove these brackets. * 11U corresponds to about 489mm and 13U is about 578mm. Precautions for Rack Mounting This unit is rated for operation at ambient temperatures ranging from 0 to 40 degrees Celsius.
Setup MGP12X Security Cover Mounting 3. Prepare the included rack-mount kit (2 supports and 6 screws). In order to prevent the control knobs of the front panel from being operated inadvertently, you can attach a protective cover using four screw holes on the unit. (Size: M3; horizontal spacing: 410mm for MGP16X and 311mm for MGP12X; vertical spacing: 208.5mm.) Yamaha does not sell such a cover; however, you can easily make one yourself and attach it to the front cover.
Quick Start Guide We’ll begin this guide by connecting a pair of speakers and generating some stereo output. Note that the operations and procedures will vary somewhat according to the input devices you are using. Step 1 Preparing the Power Supply 1. Make sure that the power switch of the unit is set to the “ ” position (off). 2. Connect the microphones and/or instruments you intend to use. For details on making connections, refer to the “Setup Examples” on pages 8, 9.
Quick Start Guide Step 4 Getting Sound to the Speakers Step 5 Using the Built-in Digital Effects 1. 1. Adjust the channel GAIN controls so that the corresponding peak indicators flash briefly on the highest peak levels. NOTE To use the level meter to get an accurate reading of the incoming signal level, turn the channel PFL switch on. Adjust the GAIN controls so that level meter indication occasionally rises above the “<” (0) level.
Quick Start Guide Built-in digital effects Your mixes can be further refined by adding ambience effects such as reverb or delay. The MGP’s internal effects can be used to add reverb or delay to individual channels in the same way as external effects processors. Reverb and Delay Time Small adjustments to the reverb/delay time can actually have a significant effect on the sound.

Controls and Connectors Where Your Signal Goes Once It’s Inside the Box The purpose of configuring an audio system around a mixer is to collect signals from all channels and mix their levels and other settings to achieve a good balance. The following simplified mixer block diagram shows how the input signal flows once it’s inside the mixer. For an overall block diagram of the MGP, see page 33.
Controls and Connectors q +48V switch and indicator Channel Control Block This switch toggles phantom power on and off. When this switch is turned on ( ), the mixer supplies DC +48V power to pins 2 and 3 of all XLR input jacks. Turn this switch on when using one or more phantom-powered condenser microphones. The indicator lights when it is turned on. Mono input section Mono and stereo input section Stereo input section CAUTION • Be sure to leave this switch off ( ) if you do not need phantom power.
Controls and Connectors t LEVELER switch and indicator When playing music from an iPod/iPhone or other audio players, the actual sound output level may differ for each song depending on the assigned category. Turning this switch on ( ) lets you have the volume adjusted automatically to a certain level, preventing sudden jumps or dips in the level. The indicator lights when it is turned on.
Controls and Connectors !3 PAN control PAN/BAL control BAL control The PAN control knob determines the stereo positioning of each mono channel signal in the GROUP 1-2, 3-4 buses or in the stereo L and R buses. For example, rotating the knob toward L moves the sound to the left (depending on the location of the knob). The BAL control knob sets the balance between left and right stereo channels.
Controls and Connectors Built-in digital effects section About the Detailed Setting Mode The detailed setting mode lets you adjust the attenuation of the CH15/16 (CH11/12) for adjusting the play level from the iPod/iPhone, and also adjust the range of the Ducker function. q Procedure 1. Press both FX1 and FX2 PROGRAM knobs simultaneously for at least two (2) seconds. 2. “P” flashes on the FX1 LED display and “A” or “d” lights on the FX2 LED display. w The mixer enters the detailed setting mode.
