AN OVERVIEW.The Avalon 747 is a high-quality audio processing device primarily used in the music and audio production industry. It’s a channel strip, which means it combines several essential audio processing functions into a single unit to streamline the recording and mixing process. Here’s a detailed description of the Avalon 747:

  1. Preamp Section:
    • The Avalon 747 features a Class A microphone preamplifier, known for its pristine and transparent sound quality. This preamp is used to amplify the low-level signal from microphones or instruments, ensuring it’s at an optimal level for recording.
  2. Compressor Section:
    • The compressor in the Avalon 747 is a tube-based opto-cell design. It provides dynamic control over the audio signal, allowing you to shape the sound by adjusting parameters like threshold, ratio, attack, and release. The optical cell design gives it a smooth and warm compression characteristic.
  3. Equalization Section:
    • The unit includes a parametric equalizer with four bands. Each band can be set to boost or cut a specific range of frequencies, allowing for precise tonal shaping. The bands are typically set for low-frequency (LF), low-mid frequency (LMF), high-mid frequency (HMF), and high-frequency (HF) control.
  4. Side-Chain Processing:
    • The Avalon 747 provides side-chain processing capabilities. This means you can use an external signal, such as a kick drum or a specific instrument, to trigger the compressor. This is useful for achieving creative dynamic effects or de-essing.
  5. Metering:
    • The unit is equipped with comprehensive VU meters that allow you to monitor input and output levels, gain reduction from the compressor, and the level of the EQ bands.
  6. Tube Circuitry:
    • One of the standout features of the Avalon 747 is its use of tube circuitry. Tubes impart a warm and harmonically rich character to the audio signal, which is often desirable in music production.
  7. I/O and Connectivity:
    • The Avalon 747 typically includes XLR connectors for input and output, making it suitable for use with microphones and line-level signals. It also features a high-impedance instrument input.
  8. Rack-Mountable:
    • The Avalon 747 is designed to be rack-mounted, which is common in professional recording and mixing studios. It is typically housed in a 2U (two rack unit) chassis.
  9. Build Quality:
    • Avalon is known for its high-quality build and construction. The 747 is no exception and is built to be durable and reliable in professional studio environments.
  10. Versatility:
    • The Avalon 747 is a versatile tool used in recording, mixing, and mastering applications. It can be used on vocals, instruments, and other audio sources, providing a rich and polished sound.

It’s often used to add warmth, character, and polish to audio recordings. Please note that specific features and specifications may vary depending on the model and version of the Avalon 747.
