Main Features

D-PRE and High-Quality Operational Amplifiers

Mono input channels are equipped with “D-PRE” Class-A discrete microphone preamplifiers. The D-PRE head amplifier features an inverted Darlington circuit used in high-end audio devices. This circuit uses multi-stage amplifying elements to ensure high current and low impedance, for an audio texture with crispness and richness in the low and mid frequencies. Combined with the specially-designed “MG01” operational amp, the overall result is full-bodied reproduction of low frequencies as well as sustained high frequencies. Input channels feature combo jacks, which can accept both XLR and TRS connectors. In addition, PAD circuitry allows line level input, to accommodate a wide variety of instruments.

Improved Convenience with Built-in Universal Switching Power Supply

The MG series features a universal switching power supply. This power supply supports input voltages of 100 V to 240 V, for stable operation even in environments where power voltage fluctuates easily. Lowering the impedance of the power supply has resulted in improved sound quality with a faster attack. An AC inlet allows simple installation in environments where portability is required, as well as when mounting the mixing console in a rack.

24 High-Quality Digital Effects (XU Models)

The XU models (MG20XU/MG16XU/MG12XU) feature 24 built-in effects that are based on SPX algorithms used by professionals. In particular, the high-quality reverb and delay expand the spatial quality of the sound with remarkable realism and naturalness.

24-bit/192 kHz USB Audio Interface (XU Models)

The XU models (MG20XU/MG16XU/MG12XU) feature a USB 2.0 audio interface capable of 24-bit/192 kHz sound quality. With the audio interface you can play back music from your computer, or use DAW software such as Cubase AI to record the mixer output. The XU models support USB Audio Class 2.0 so you can use them with USB Audio Class 2.0 compliant tablets and other devices, without the need to install drivers. The USB protocol uses asynchronous data transfer. Audio data is transferred based on a highly precise audio clock signal from the MG, for high quality recording and playback.

1.Turn the [PROGRAM] knob to select the desired effect, and then press the knob to enable it.

The selected effect program number flashes in the display. For details about available effects, see the Effect Programs on page 33.

2.Turn on () the [ON] switch for [FX RTN].

3.Turn on () the [ST] switch for [FX RTN].

4.Raise the [FX RTN] fader to the “0” position.

5.Use the [AUX (2, 4)/FX] knobs to adjust the effect depth for each channel.

6.Use the [FX RTN] fader to adjust the overall effect depth of the selected effect.

You can use the [PARAMETER] knob (page 23) to adjust effect parameters such as reverb time and delay time. For details about the parameters of each effect that can be adjusted with the [PARAMETER] knob, see page 33.

Using Reverb and Delay

Your mixes can be further enhanced by using the built-in ambience effects such as reverb or delay.

Reverb and Delay Time

The optimum reverb time for a piece of music will depend on the music’s tempo and density, but as a general rule longer reverb times are good for ballads, while shorter reverb times are more suited to up-tempo tunes. Delay times can be adjusted to create a wide variety of repeating rhythmic effects. When adding a delay to a vocal, for example, try setting the delay time to dotted eighth notes ( e. ) corresponding to the tune’s tempo.

Reverb Level

While working for many hours on a mix, your sense of hearing will start to dull slightly. This can lead to the perception that tracks with excess processing sound like the perfect mix. To avoid falling into this trap, start with reverb level all the way down, then gradually bring the reverb into the mix until you can just hear the difference. Any more than this normally becomes a special effect or, worse yet, makes the sound muddy and indistinct. In general, you don’t want reverb to dominate the mix, so you should apply it judiciously.
