Mixing Fundamentals
Mastering the Mix: This section details core mixing techniques using the Qu-16, covering channel control, equalization, dynamics, and auxiliary send/return configurations.
Channel Strip Controls
Each Qu-16 channel strip offers extensive control over your audio signal. Begin with the gain control, carefully setting input levels to maximize signal-to-noise ratio without clipping. Next, utilize the high-pass filter to remove unwanted low-frequency rumble. The four-band parametric EQ allows precise tonal shaping, while the compressor provides dynamic control.
Further refine your sound with the gate, controlling noise floor. Aux sends route signals to monitor mixes or external effects. Pan controls position the sound within the stereo field, and the fader adjusts the channel’s overall level. Finally, solo and mute buttons offer quick isolation and silencing of individual channels.
EQ and Dynamics Processing
The Qu-16’s EQ provides four fully parametric bands per channel, offering precise frequency control. Adjust frequency, bandwidth (Q), and gain for tailored tonal shaping. Dynamics processing includes a compressor and gate. The compressor controls dynamic range, smoothing out peaks and increasing perceived loudness. Adjust threshold, ratio, attack, and release for desired effect.
The gate reduces noise by silencing signals below a set threshold. Fine-tune threshold, range, and hold time for clean, controlled audio. These tools are essential for polishing individual channels and achieving a professional mix.
Auxiliary Sends and Returns
The Qu-16 features multiple auxiliary sends, enabling the creation of monitor mixes and effects routing. These sends allow you to route channel signals to external effects processors or independent headphone mixes for performers. Each send is individually configurable, with pre/post-fader options for flexible control.
Auxiliary returns bring the processed signal back into the mixer, integrating external effects seamlessly. Adjust return levels and pan for balanced placement within the stereo field. Utilize these tools to enhance your mix with depth and dimension.
