Analog mixers are the traditional, non-digital variety that rely on physical knobs, faders, and buttons to control audio levels and parameters. These mixers are often preferred by engineers who value the tactile experience and warm, analog sound.
Digital Mixers
Digital mixers, on the other hand, use digital signal processing (DSP) to manipulate audio signals. These mixers often feature touchscreen interfaces, motorized faders, and advanced processing capabilities.
Hybrid Mixers
Hybrid mixers combine the best of both worlds, offering analog-style controls and digital processing capabilities. These mixers provide a flexible and versatile solution for engineers who need to adapt to different recording environments.
Connection Methods and Configurations
Now that we’ve covered the basics of mixer types and configurations, let’s explore the different connection methods and configurations you can use to link two mixers together.
Parallel Configuration
In a parallel configuration, both mixers are connected to the same audio source, and the outputs are combined to create a single, blended mix. This setup is ideal for:
- Creating a redundant system: By connecting two mixers in parallel, you can ensure that your audio signal remains intact even if one mixer fails.
- Increasing the overall gain: Combining the outputs of two mixers can provide a boost in overall gain, making it easier to drive long cable runs or power hungry devices.
Series Configuration
In a series configuration, the output of the first mixer is connected to the input of the second mixer, creating a cascading effect. This setup is ideal for:
- Creating a complex audio routing system: By connecting mixers in series, you can create complex audio routings and configurations that would be impossible with a single device.
- Processing audio signals in stages: Series configurations allow you to process audio signals in stages, applying different effects and processing techniques to each stage of the signal chain.
Submix Configuration
In a submix configuration, the output of the first mixer is connected to a subgroup or aux bus on the second mixer. This setup is ideal for:
- Creating a submix: By connecting the output of the first mixer to a subgroup or aux bus on the second mixer, you can create a submix that can be processed independently of the main mix.
- Providing a separate mix for in-ear monitors or stage wedges: Submix configurations are often used to provide a separate mix for in-ear monitors or stage wedges, allowing performers to hear a customized mix that’s tailored to their needs.
Connection Options and Cables
When connecting a mixer to a mixer, you’ll need to choose the right cables and connection options to ensure a reliable and high-quality audio signal.
XLR Cables
