[. . . ] Owner's Manual Precautions Quick Start Guide Troubleshooting pages 4, 5 pages 12 to 14 page 27 EN 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. Explanation of Graphical Symbols CAUT I ON RISK OF ELECTRIC SHOCK DO NOT OPEN The lightning flash with arrowhead symbol within an equilateral triangle is intended to alert the user to the presence of uninsulated "dangerous voltage" within the product's enclosure that may be of sufficient magnitude to constitute a risk of electric shock to persons. The exclamation point within an equilateral triangle is intended to alert the user to the presence of important operating and maintenance (servicing) instructions in the literature accompanying the product. CAUTION: TO REDUCE THE RISK OF ELECTRIC SHOCK, DO NOT REMOVE COVER (OR BACK). [. . . ] The indicator lights when it is turned on. NOTE If an audio player other than iPod/iPhone is connected to the input jacks (LINE) on the rear panel, initially adjust the input level according to the softest part (lowest level) of the song, and then turn on the LEVELER switch. Adjust the input level so that the level meter indication occasionally rises above the "<" (0) level while the PFL switch is on. o Equalizer (HIGH, MID, and LOW) This three-band equalizer adjusts the channel's high, mid, and low frequency bands. Setting the knob to the "t" position produces a flat response in the corresponding band. Turning the knob to the right boosts the corresponding frequency band, while turning to the left attenuates the band. The upper knob sets the center frequency for the mid range, while the lower knob sets the amount of attenuation or boost (counterclockwise/clockwise) for the range. For the CH9/10 and CH11/12 (on the MGP16X), and CH5/6 and CH7/8 (on the MGP12X), the attenuation/boost can only be set at a fixed 2. 5kHz center frequency. The following table shows the EQ type, frequency, and cut/ boost range for each of the three bands. Band HIGH MID LOW Type Shelving Peaking Shelving Frequency 8kHz 2. 5kHz* 125Hz ±15dB Cut/Boost range y GAIN control Adjusts the sensitivity of the input signal. Monaural channels have a 26dB switch (w) that lets you change the range of this control. The adjustable sensitivity range is as follows. Mono channel 26dB switch ON OFF Range -34dB to +10dB -60dB to -16dB * The MID frequency can be adjusted from 250Hz to 5kHz. The MID frequency is 2. 5kHz when the MID frequency control is set at the center position. Stereo channel -34dB to +10dB !0 AUX1 PRE, AUX2 controls These knobs adjust the channel's signal levels sent to AUX buses 1 and 2. Each knob controls the signal sent to the corresponding AUX bus. These knobs should generally be set close to the "t" (nominal) position. The AUX1 control adjusts the signal before the channel fader (pre-fader). The signal adjusted by the AUX2 control is determined by the PRE switch (!1). u COMP control and indicator Adjusts the amount of compression applied to the channel. As the knob is turned to the right the compression ratio increases while the output gain is automatically adjusted accordingly. The result is smoother, more even dynamics because louder signals are attenuated while the overall level is boosted. The COMP indicator will light when the compressor operates. NOTE Avoid setting the compression too high, as the higher average output level that results may lead to feedback. !1 PRE switch This switch selects whether the signal sent to the AUX 2 bus is taken after the equalizer but before the channel fader (prefader), or after the channel fader (post-fader). When the switch is on ( ), the mixer sends the pre-fader signal to the AUX2 bus, so that the AUX2 output is not affected by the fader. i STEREO IMAGE switch This switch selects the output signal by switching the input stereo signal to one of the following three signal types. · MONO : Mono signal · BLEND : Stereo signal in which left and right inputs are mixed in a certain percentage for a more natural stereo image.
