Which items should be checked before starting a recording session?

Before starting a recording session, checking the digital mixer, input and output connections, and power settings is essential for ensuring that the equipment operates correctly and efficiently. The digital mixer is a key component for managing audio levels and routing, so ensuring it is functioning properly is critical. Input and output connections need to be checked to confirm that all microphones and other audio sources are correctly plugged in and configured to transmit sound without issues. Power settings must be verified to make sure that all devices are powered on and set to the correct voltage or settings to avoid interruptions during recording.

While other options contain relevant items related to sound quality and comfort during recording, they do not focus on the essential technical aspects necessary for a successful recording session. For instance, checking audio levels and speaker placement is important but comes after ensuring all connections and equipment are functioning. Similarly, environmental noise and chair arrangements, while relevant to the overall setup, are secondary to the foundational technical checks needed for recording.
