Explanation of Graphical Symbols Explication des symboles 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. l’éclair avec une flèche à l’intérieur d’un triangle équilatéral est destiné à attirer l’attention de l’utilisateur sur la présence d’une « tension dangereuse » non isolée à l’intérieur de l’appareil , pouvant être suffisamment élevée pour constituer un risque d’électrocution. [. . . ] the adjustable gain range is as follows. [PAD] switch ON OFF Range -6 dB to +38 dB +20 dB to +64 dB o [LINE /USB ] switch (XU models) Switches the audio source input on CH19/20 USB IN {CH15/ 16 USB IN} {CH11/12USB IN} between the [LINE] stereo input jack and the [USB 2. NOTE The volume input from computers through [USB 2. 1 [AUX 1 – 4] knobs [PRE] switches [AUX (2, 4)/FX] knobs MG20XU/MG16XU: [AUX1], [AUX2 – 3], [AUX4/FX] MG20/MG16: [AUX1], [AUX2 – 4] MG12XU: [AUX1], [AUX2/FX] MG12: [AUX1 – 2] 3 Band [MID] Sweep 3 Band 2 Band The levels of each signal sent to the AUX 1 – 4 buses from each channel can be adjusted independently. On stereo input channels, the Line L (odd) and Line R (even) input signals are mixed before being sent to each AUX bus. Adjust the knobs so that they are near or at the “t” (nominal) position. NOTE • The [AUX1] knob indicated “PRE” adjusts the level of the prefader signal (before fader adjustment). Equalization Types and Characteristics 3 Band [MID] Sweep MG20XU/ MG20 MG16XU/ MG16 MG12XU/ MG12 CH 1 – 12 CH 1 – 8 — 3 Band CH 13/14 – 19/20 CH 9/10 – 15/16 CH 1 – 7/8 2 Band — — CH 9/10 – 11/12 • The [PRE] switch on [AUX1] and [AUX2] can be used to select whether the pre-fader ( ) (the signal before fader adjustment) or post fader ( ) (the signal after fader adjustment) signal is sent to the AUX bus by the [PRE] switch. € The [AUX4/FX] and [AUX2/FX] knobs are used to adjust the level of the signal sent to the FX bus (built-in effects) in addition to the AUX bus. The same signal level is sent to the AUX buses and FX buses connected to these knobs. The equalizer shapes the high, mid, and low audio frequencies. Turning the knob to the right amplifies (boosts) the corresponding frequency band, while turning it to the left attenuates (cuts) the band. Setting the knob to the middle “t” position produces a flat response in the corresponding band. The upper knob sets the variable mid frequency, while the lower knob sets the amount of attenuation or boost (counterclockwise/clockwise) for the range. The following table shows the EQ type, frequency, and cut/ boost range for each of the three bands. 2 [PAN] knobs [PAN/BAL] knobs [BAL] knobs * The signals from mono input jacks of the MG20XU/MG20 and MG16XU/MG16 can be adjusted from 250 Hz to 5 kHz. € PAN: Sets the position of the sound image within the stereo field. This knob adjusts the volume balance of each channel sent to the STEREO L/R bus. When the knob is set to the 12 o’clock position, the channel’s sound will be sent to the L and R of the STEREO L/R bus at the same volume. In this case, the sound image is positioned at the center. If the bus assign switch [1-2] or [3-4] is pressed, this knob adjusts the volume balance sent to the GROUP bus. When the knob is set to the 12 o’clock position, the same volume is sent to each GROUP bus. [. . . ] RCA type pin jacks are often color coded: white for left audio channel and red for right audio channel, for example. red White 34 MG20XU/MG20/MG16XU/MG16/MG12XU/MG12 Owner’s Manual Appendix Rack Mounting The MG12XU/MG12 require at least 10 U* of rack space. To take into account the cable connections, we recommend to ensure 11 U* of rack space. The MG20XU/MG20/MG16XU/MG16 require at least 12 U* of rack space. [. . . ]
