Understanding Your Needs
Before getting into the techniques, what is your purpose? The mixer suitable for a live band will not be the same as the one you might want for a home studio or podcasting setup. These are the important questions you need to ask yourself:
- What do you plan to use the mixer for?
Live sound, recording, streaming, or broadcasting? - How many inputs and how many outputs?
Microphones, instruments, and external devices. - Would you rather analog or digital?
Each has its pros and cons. - What’s your budget?
Mixers can be basic, cheap models or high-end pro gear.
Types of Audio Mixers
Audio mixers are indispensable devices in sound production, whether for live events, in the studio, or broadcasting. They vary by type according to their function and use.
- Analog Mixers: These oldest types of mixers often use knobs and sliders to control audio feed. They are also easy to use and favored for live sound mixing for this reason, as well as for reliability and ease of use.
- Digital Mixers: These mixers use Digital Signal Processing (DSP) to provide features such as preset recall effects and can be controlled remotely using software or mobile apps. These are commonly used in pro studios and big events.
- Powered Mixers: These come with internal amplifiers, so there is no need for external amps. They are perfect for little spaces and portable PA systems.
- Software Mixers: Virtual mixers in digital audio workstations (DAWs) allow for editing and mixing of sound on a computer.
Different varieties are available, catering to various requirements such as live acts and studio recordings.
Key Features to Consider
There are some key features you should look for when buying an audio mixer:
- Number of Channels: The number of microphones, instruments, or other audio sources that can be plugged in. Choose based on your setup.
- EQ (Equalization) Controls: Shapes sound quality by adjusting the bass, mid, and treble frequencies.
- Built-in Effects: Mixers can offer reverb, delay, and compression to improve audio without external processors.
- Analog vs Digital: Analog’s tactile control versus digital’s presets, automation, and remote access.
- Phantom Power: Required for condenser microphones.
- Connectivity: Seek USB, Bluetooth, or Wi-Fi capabilities to ensure smooth integration with computers and recording apps.
- Aux Sends & Returns: These are for effects outside VST plugs or custom monitoring mixes.
