What Is A Mixer?
A mixer, also known as a mixing console or audio mixer, is an electronic device that serves as the central hub for combining, balancing, and mixing different sounds and audio signals. These signals can come from various sources like microphones, instruments, synthesizers, or previously recorded audio.
As a multifunctional device, a mixer lets you connect multiple inputs, such as microphones and instruments, and then sends the combined output elsewhere, like through your PA speakers.
The mixer’s ability to blend sound signals is determined by the number of input and output channels it has. For instance, an 8×2 mixer means you’re mixing 8 input channels into 2 output channels for a recording.
Analog Mixers
Analog mixers are a type of mixer that processes analog signals. They’re made up of several parts, including auxiliary, channel faders, equalization knobs, bus sends, and pan pots. The output section of an analog mixer sends the balanced mix to the track recorder.
This type of mixer takes signals from the input, blends them together, and then sends them on to the recorder. It also gets return signals from effects like reverb and delay. The output section also connects to the monitor amplifier, and the meters adjust to the recording volume to help avoid sound distortion.
Analog mixers are generally thought to have a warmer, more natural sound. They’re often simpler to use and cheaper than digital mixers. However, they don’t have the advanced features and flexibility of digital mixers.
Digital Mixers
Digital mixers can accept both digital and (more common) analog signals. They work using electronic sound transmission and are more expandable, meaning you can connect a greater number of external devices.
A digital mixer changes analog signals into digital format for processing. Then, it changes them back to analog signals when it outputs the sound. Digital mixers offer more flexibility and features, such as the ability to save and recall settings, built-in effects, and remote control capabilities.
They can handle more inputs and outputs and offer more control over the sound. This includes the ability to shape and manipulate the sound in ways that aren’t possible with an analog mixer. However, digital mixers can be more complex to operate and may require a learning curve if you’re used to working with analog mixers.
In professional audio, a digital mixing console (DMC) is a type of digital mixer. It’s used to combine, route, and change the dynamics, equalization, and other properties of multiple audio input signals using digital signal processing. DMCs are typically used in recording studios, public address systems, sound reinforcement systems, broadcasting, television, and film post-production.
DMCs offer a wealth of control features for each input channel and robust built-in effects. Many digital mixers have controls that mimic the classic look and feel of analog mixers. Third-party plugins can add further functionality.
When you’re deciding between a digital or analog mixer, remember that one isn’t necessarily superior to the other. Both have their own sets of advantages. Your choice will come down to your personal preference and how you plan on using the mixer.
Contrasting Analog and Digital Mixers
When designing a sound system, the mixer is a pivotal component. One of the initial decisions you’ll face is whether to opt for an analog or digital mixer. This decision can significantly influence the ease of operation and cost-effectiveness of your system.
Workflow of Analog And Digital Mixers
The workflow of a mixer is influenced by its layout and the arrangement of your inputs. For example, if you’re utilizing a digital console with a limited number of faders, you’ll need to strategize how your inputs will occupy them. It’s often simpler to mix from the 8 or so VCA faders than from all of your individual channels, especially on smaller consoles that only offer 8 input faders on the surface.
Each input you connect to the console corresponds to a different channel on a mixer. These channels are organized vertically into “channel strips.” Each strip usually has EQ knobs for low, mid, and high frequencies and compression. There’s also a stereo pan adjustment to assign left or right speakers, channel faders, and gain adjustments for volume.
There are main output level faders that control the volume of the entire track. Some mixers include special effects adjustments located near the main output faders, to the console’s left. And of course, there’s always a line output (usually an XLR jack) so you can record or amplify the sound straight from the mixer.
Analog Vs Digital Mixers
Analog mixers, being more traditional, are generally less expensive. They have a reasonably straightforward signal routing, with inputs hard-wired to appropriate channel strips. Their control layout logically follows the mixer’s signal flow, making it relatively easy to understand. However, they can only connect to a limited number of external devices. High-end analog mixers are also significantly larger in size.
Digital mixers, conversely, are gaining popularity due to their convenience, expandability, and resistance to noise. They process audio signals in digital form, enabling a number of mixing functions that aren’t possible in analog systems. Digital mixers feature memory to store settings and built-in signal processing functions. They can connect to a wide variety of external devices.
Digital mixers allow numerous functions to be assigned to a single control. Function switching can be done either via physical controls or virtual controls on a display. They also have more complex routing options and grouping assignments. They can provide sophisticated channel equalizers and in-line dynamics, as well as effects and output processing such as graphic EQs.
Many digital mixers support network audio protocols like AVB and Dante. This allows expansion with digital stage boxes and personal monitor systems. However, they’re more expensive and can be complex for beginners.
The choice between analog and digital mixers also impacts the sound quality. Analog mixers provide a clean, unaltered sound. However, they’re more susceptible to conditions such as dust, dirt, and power surges. These conditions may add extra distortion and white noise to the output.
Digital mixers process digital data, eliminating the white noise, buzzing, and ticking noises that come with recording. Analog mixers are simple, reliable, and more affordable, but they aren’t as versatile or compact as digital mixers. Digital mixers have built-in effects, remote control features and usually have more channels in less space. However, they can also be more expensive and challenging to master.
Your personal preferences and workflow can also influence your choice and use of mixers. Some people prefer to replicate the best of an analog workflow within modern DAWs. This adds the warmth and tightness of analog mixing without draining creativity by having too many options.
As you gain more experience, you may develop preferences in how your console is laid out. Keeping important inputs on the channels closest to the master section or all drums on the same layer or page for easy adjustments can be beneficial. Effects returns, VCAs/DCAs, Groups, and AUX buses are other elements to consider for optimal mixing.
