  1. "Remember those ground posts on turntables with the screw terminals where you could attach a ground wire to keep hum at bay? Have you ever seen ground posts on anything else? Of course not!" Craig's memory is a little faulty here. Turntables had a ground _wire_ that was permanently attached. The ground post, where you connected the spade lug on the other end of the turntable's ground wire was on the receiver or preamp. So convenient - you didn't have have to buy a piece of wire to ground your turntable's innards, nor did you have to solder anything or drill any holes.
  2. Don't artists use more than one or two microphones? So many companies have interfaces along the same model as these new Mackies and they continue to get better as far as raw audio quality. But high quality 4-mic interfaces that connect via USB seem to be as scarce as ever. I suppose if you're creative (or maybe indecisive) enough to want to record more than two channels, you're "pro" enough to have a Mac or one of the rare PCs with Thunderbolt.
  3. Always good to see Sister Rosetta Tharpe included in such a list. She should be #1, though. The clip here is pretty tame, but she's where Chuck Berry got his licks, and without Chuck Berry, where would real rock and roll be?
  4. "Don't ever go over 0 VU when recording digitally." Digital gear doesn't have VUs or VU meters. The level you don't want to exceed, and actually, that you can never exceed, is 0 dBFS. If you're using a VU meter for reference, for example on an analog mixer or mic preamp, you need to establish a relationship between 0 VU on the analog meter and 0 dBFS on the digital meter. Usually the system is calibrated so that at 0 VU, you'll have a recording level somewhere between -14 and -20 dBFS, depending, if you have a choice, of how much headroom you want to allow. See my article entitled Mete
  5. Here are some important details for those who have never done anything like this before. First, readers may not know what a "signal generator" is. You don't need a piece of calibrated lab equipment for this. Most DAWs and audio editing programs have a function to generate a sine wave. For something more portable (I hate to be tied to my computer workstation when doing shop tests or troubleshooting) there are web resources for downloading WAV or MP3 files of sine waves. You can transfer those to a handheld recorder and that becomes your test generator. Alternatively, there are a few apps f
  6. "While I don't see guitar companies doing away with the 3/4†jack anytime soon," I think you mean 1/4" jack. There was a Gibson system (the Les Paul Recording) that used a balanced connection between guitar and amplifier on an XLR connector, but they left the 1/4" jack so the guitar could be played with a conventional amplifier.
  7. It's about time somebody wrote an article like this. Guitar switches and knobs are notorious for being unmarked and in the "well, everybody knows what that switch does" category. The real meat here is in your last paragraph, except that I've never seen a manual for a guitar (maybe because I've never bought a new electric guitar) or much of an explanation on the manager's web site. Ask a clerk? Ummmm . . . maybe they know more about guitars than microphones or mixers. But thanks for the starter info.
  8. My tool of choice for holding nearly anything small enough to solder with a soldering iron is a small Jorgensen parallel jaw wooden handscrew. With two of them, it's like having four hands. https://ponyjorgensen.com/products/specialty-clamps/
  9. The problem with fretting one string to get it to the pitch of the next higher string is that frets aren't always that accurate, and even if they're spaced mathematically accurate, the bridge is in the correct place, and the instrument is set up well, you're still at the mercy of the tempered scale - unless of course you have one of those kinky oddly fretted fingerboards that attempt to compensate for what was designed for Mr. Bach's Well Tempered Clavier. One system that works better most of the time is to compare octaves. It's easy enough to hear if two notes an octave apart are identi
  10. Hey, Phil - Thanks for the review. I've been trying to get one of these for a review for over a year now. Glad they're finally getting out and I'll get mine. In the spirt of the Pro Review, I have a question for you: "You'll also find two large rotary controls on the front panel. The one near the display is used to select various menu items, and has a built in push-to-select switch. The other large knob is a main output level control, and adjusts the level of the rear panel 1/4" TRS balanced +4dBm output jacks. These jacks provide a summed output of all the recorded tracks courtes
  11. Audio Engineering Society 2014 Convention Los Angeles, California October 9-12, 2014 ©2014 – Mike Rivers The Audio Engineering Society returned to Los Angeles for the 137th annual convention for the first time since 2002 after several years of West Coast shows in San Francisco. When first moving from LA to San Francisco the exhibitors and attendees were enthusiastic about the change, but things change and it was time for a fresh venue. Attendees and exhibitors were enthusiastic about the move, and the uptick in the audio industry made this the biggest and best attended US show in several yea
