Mixing It Up: The Ultimate Guide to Running a Mixer into Another Mixer

When it comes to setting up a live sound system or a recording studio, mixers are an essential component. But have you ever wondered if you can run a mixer into another mixer? This question may seem simple, but the answer is not as straightforward as you might think. In this comprehensive guide, we’ll delve into the world of audio mixing and explore the possibilities, limitations, and best practices of running a mixer into another mixer.

Understanding the Basics of Audio Mixing

Before we dive into the specifics of running a mixer into another mixer, it’s essential to understand the fundamentals of audio mixing. An audio mixer, also known as a mixing console or soundboard, is an electronic device that combines multiple audio signals into a single output signal. This process involves adjusting the levels, tone, and other parameters of each signal to create a balanced and harmonious sound.

In a typical live sound setup, a mixer is used to combine the audio signals from various sources such as microphones, instruments, and playback devices. The mixed signal is then sent to a power amplifier and finally to the speakers. In a recording studio, the mixer is used to combine the audio signals from various sources and send them to a recording device or a digital audio workstation (DAW).

The Importance of Signal Flow

One critical aspect of audio mixing is signal flow. Signal flow refers to the path that an audio signal takes from the source to the final output. Understanding signal flow is crucial when setting up a mixer, as it determines the quality and integrity of the audio signal.

In a typical mixer setup, the signal flows from the input channels to the master section, where it is processed and mixed. The mixed signal is then sent to the output section, where it is prepared for distribution to the speakers or recording device. Signal flow is critical because it can affect the gain structure, noise floor, and overall quality of the audio signal.

The Possibilities of Running a Mixer into Another Mixer

Now that we’ve covered the basics of audio mixing and signal flow, let’s explore the possibilities of running a mixer into another mixer. There are several scenarios where this setup might be necessary or desirable:

Submixing

One common scenario is submixing, where you need to combine multiple audio signals from a specific group of sources, such as drums or vocals, before sending them to the main mixer. In this case, you can use a smaller mixer to submix the signals and then send the mixed signal to the main mixer.

For example, in a live sound setup, you might use a small mixer to submix the drum microphones and then send the mixed signal to the main mixer. This setup allows you to create a more balanced and manageable signal before sending it to the main mixer.

Expanding Channel Count

Another scenario is when you need to expand the channel count of your main mixer. If you have a large number of audio sources and your main mixer doesn’t have enough channels, you can use a second mixer to expand the channel count. This setup is common in large live sound systems or recording studios where you need to handle a large number of audio sources.

For example, you might use a 16-channel mixer as your main mixer and connect a second 16-channel mixer to expand the channel count to 32 channels. This setup allows you to handle a larger number of audio sources without sacrificing signal quality or integrity.

The Advantages of Running a Mixer into Another Mixer

Running a mixer into another mixer offers several advantages, including:

  • Increased flexibility: By using multiple mixers, you can create a more flexible and adaptable sound system that can handle a variety of scenarios and configurations.
