Out to groups (for control over multiple channels from one group channel).High-pass filter (used to cut out frequencies below a fixed point).Gain control (controls how much of the signal you are letting into the system).From the signal input, it usually follows as such: Once the signal is going to a channel, it tends to follow a general path that can vary slightly from one mixer to the next. Naturally, you have sources from the stage, but there are also have sources such as a computer, tablet, CD player, and audio feeds from video devices. The primary component that takes care of all these transfers is the mixer.Ĭoming into the mixer are a variety of sound sources that will all be assigned to the channels on the mixer. Destinations can be house loudspeakers, floor monitors, recording software, and even church nursery loudspeakers. The sound booth is like a giant airport where signals are coming in and going out, from multiple sources to multiple destinations. Consider this as the general directionality of the audio signal – from a source to a destination. For example, a singer’s voice is picked up by the microphone which, through a series of components, makes its way out to the house speakers. Asking For DirectionsĪn audio signal travels from the source towards some sort of output. Then we see what happens to that signal once it gets to the sound booth.
THE SIGNAL PATH HOW TO
Learning how to set up the stage, we see how the signal flows from an electric guitar to a pedal board to a direct (DI) box and then into a stage jack. In every sound system, signal flow is the flow of the audio signal from the sources of input to the places of output, from source to loudspeaker. You might say it was my first exposure to signal flow. One lesson was tracing all the pipes in the basement so I could tell which pipes had fresh water and which ones carried the other stuff. Growing up in a 100-year-old home, I learned how to fix plumbing problems.
