When displaying your reference picture from Pro Tools on an external screen, you need to be mindful of the video sync offset. This refers to the delay between the audio and video playback, which can cause synchronization issues. It is important to ensure that the audio and video are perfectly aligned to avoid any discrepancies or timing errors.

The cable that runs from a 192 I/O to the HD Accel card is called DigiLink. This cable is specifically designed for connecting Avid audio interfaces to Pro Tools HD systems, allowing for high-quality audio transfer and synchronization between the devices. USB and Serial are not the correct answers as they are not specific to this particular connection. Avid Pro Connect is also not the correct answer as it is a software application for remote control and collaboration, not a physical cable.

The proximity effect refers to the increase in low frequencies when speaking or singing closer to a microphone. This phenomenon occurs because of the way sound waves interact with the microphone's diaphragm. When the sound source is close to the microphone, the bass frequencies are emphasized, resulting in a warmer and richer sound. This effect is commonly used in audio recording and broadcasting to achieve a desired tonal quality.

In Pro Tools 9 or 10, non HD, you cannot import multiple videos into the same session. This means that you are limited to working with only one video file at a time in these versions of Pro Tools. Importing multiple videos into the same session allows for more flexibility in working with multiple video sources simultaneously, which is not possible in Pro Tools 9 or 10, non HD.

The standard reference tone used to calibrate audio equipment is typically set at a frequency of 1kHz. This frequency is commonly used because it falls within the range of human hearing and is easily distinguishable. It serves as a benchmark for audio equipment calibration, ensuring that the equipment reproduces sound accurately and consistently.

MIDI velocity is a parameter that determines the intensity or volume of a note played on a MIDI instrument. It ranges from 0 to 127, which gives a total of 128 control values. Therefore, the correct answer is 128.

The track meters in Pro Tools show levels in dbFS. dbFS stands for decibels Full Scale, which is a measurement of the audio signal's level in relation to the maximum digital level allowed. This measurement is commonly used in digital audio systems to ensure that the audio signal does not exceed the maximum level and cause distortion or clipping.

With a Time Machine backup on a Mac, you cannot boot directly from the drive. Time Machine backups are designed to restore files, applications, and system settings, but they do not allow you to boot the Mac directly from the backup drive. Booting directly from the drive would require creating a bootable clone or using a different backup solution.

An XLR cable carries audio signals, not voltage. The pins on a 3-pin XLR cable are designated for different purposes. Pin 1 is used for the ground connection, pin 2 carries the positive audio signal, and pin 3 carries the negative audio signal.

AVI is not a Quicktime (.MOV) movie codec. AVI (Audio Video Interleave) is a multimedia container format developed by Microsoft. It is commonly used on Windows operating systems but is not compatible with Quicktime. Quicktime (.MOV) movie codecs include Apple ProRes, H.264, and Photo-Jpeg, which are all widely used for video compression and playback on various platforms.
