What is the first question to ask when troubleshooting head issues?

When troubleshooting head issues in recording equipment, the first question to ask is whether the recorder is plugged in. This is a fundamental step in the troubleshooting process because, without power, none of the device’s functions will operate, including the recording heads. Ensuring that the recorder is plugged in eliminates any basic power-related issues before delving into more complex troubleshooting steps. This approach aligns with a logical hierarchy in troubleshooting, where the most fundamental and easily verifiable issues are addressed first to streamline the process.

Moving on to the other options, they pertain to subsequent steps in troubleshooting. Checking indicators of recording channel activity comes after confirming that the device is powered since if it's not plugged in, there won't be any activity to observe. Likewise, verifying that all cables are connected correctly and ensuring that software is properly installed are necessary checks but are contingent on the assumption that the recorder is already powered. Thus, confirming power is the essential first step before addressing any other potential complications.
