  1. OT: Best all-round DI box?

    What I want most in a Direct box is to isolate me from whatever signal I want to record. I want a transformer, a 20 db pad and a ground lift History A vintage Wolfbox custom-made by audio engineer Ed Wolfrum in the 1960s. Passive direct boxes first appeared in the United States in the middle 1960s, most notably in Detroit at radio stations and recording studios like "Motown", "United Sound Systems", "Golden World Records", Tera Shirma Studios and the Metro-Audio Capstan Roller remote recording truck. These DIs were custom made by engineers like Ed Wolfrum with his "Wolfbox" and by concert sound companies to solve certain problems associated with amplifying electronic musical instruments, especially electric guitars. These boxes typically contained an audio transformer (like the Triad A11J through 1974) with a turns ratio from approximately 8:1 to 12:1, and thus an impedance ratio of around 144:1. With this kind of transformer, the output voltage of the instrument is stepped down to a range compatible with the typical mixing console's microphone preamp. The typical console preamp input impedance of 1,500 ohms would appear to the electronic instrument as a high input impedance of 216,000 ohms.[1] The passive direct box was suitable for most electronic musical instruments but it negatively colored the sound of ones with weaker output signals, such as Fender Rhodes pianos and Fender Precision Basses with single-coil pickups. To accommodate these instruments, active direct boxes were designed containing powered electronic circuitry which increased the input impedance from about 200,000 to above 1,000,000 ohms. In 1975, a 48-volt phantom powered active direct box was designed for Leon Russell's recording studio, its circuitry published in dB, the sound engineering magazine.[2] The sound company Tycobrahe, known for supporting large rock festivals such as California Jam, offered an active direct box for sale in 1977, a model capable of +9 dBm line level output, with a built-in attenuator to compensate for various input levels.[3][4] https://en.wikipedia.org/wiki/DI_unit Build your own passive direct box. https://www.diyrecordingequipment.com/blogs/news/15851820-how-to-build-a-boutique-passive-di Deane Jensen http://www.jensen-transformers.com/history/

  5. The True History of the Traveling Wilbury's

    "Wilbury" was a slang term first used by Harrison during the recording of Cloud Nine with Jeff Lynne. Referring to recording errors created by some faulty equipment, Harrison jokingly remarked to Lynne, "We'll bury 'em in the mix"
  6. Timecode slate

    Editors tell me they only able to know what scene is playing is because of electronic slates, timecode, and sound reports - they aren't going to get that info from the camera dept. No better reference than a happy editor.
  7. Red Weapon 8K Audio Issue

    My approach to Reds is if it works I am happy, If it doesn't work I don't worry about it. No one ever bought a Red because they liked the way it reliably dealt with sound. Insanity: doing the same thing over and over again and expecting different results.

  11. My backround is in music recording working with MCI and Harrison consoles, very flexible recording and mixing, but filled with IC's, integrated circuits. They sounded great to us but I always ended up looking to equalizers to make sounds more "musical". One day we were unable to book our own studio and had to go a room with an Neve console, a bit of a bother because what would be a button push previously now became a patch cord inserted. Instead of the monitor pot being in line it was now a separate monitor section on the side. We had a good assistant and were able to get our days work started. After we finished tracking and were playing back I realized that things had changed forever for me, I had wanted to hear a quality in the sound and I had finally found it. Rupert Neve is the creator of that sound and he didn't care what other folks did, he was on a mission to please his own ears.
