    Fostex_M88_M77These mics, like the Fostex RP headphones, use a unique method of transduction that combines elements of dynamic, ribbon, and condenser-mic design.  I’m not 100% sure why they are termed ‘regular phase,’ but I suspect that it might be because the design works without any driver suspension.  You may not have realized before, but consider a generic woofer, and the acordian folds in the suspension:  at any moment of driver excursion, portions of the suspension will necessarily be moving out-of-phase with the cone.  This is a significant cause of transducer distortion.  By eliminating the suspension, that particular distortion factor is eliminated.  Here’s a cutaway of the Fostex design:

    I’ve seen a few of these things on eBay from time to time, generally from ex-US sellers, and I’ve never seen one in the flesh, so I imagine that they are pretty rare in the US.  The catalog that I’ve scanned above was actually printed in Canada, so I can’t even say for sure if these were sold in the US.  I am super-curious, though, as I have always really loved the Fostex RP headphone line (I own a pair of T50, a pair of T40, and several pairs of T20s), and I’ve also had good luck with the classic Fostex full-range Banana Cone hi-fi drivers, so these mics seem like something I might dig.  Anyone?

    ***************************************************************

    I was recently at the excellent DOX center in Prague to see a mid-career retrospective of the Czech composer/artist Milan Gustar. Gustar could be described as a minimalist electronic composer.  His pieces seem concerned with the perception of sound and with systems of describing, organizing, and controlling sound.  One of the two pieces on display for actual playback (as opposed to simply a graphic score) was his TWIST; it was quite beautiful, and you can hear it here.  Anyhow, Gustar’s work has unsurprisingly also taken him into the realm of research, and at the DOX I was able to purchase the two above-depicted hardbound Czech-language volumes, approx. 400pp and 500pp respectively.  Although I can decipher very little of the text, these books are incredibly fascinating, with hundreds of photos and diagrams, and offer an extremely detailed account of the history of electro-mechanical instruments (vol. 1) and electronic instruments (vol. 2).  You can read detailed descriptions of both books at these English-language links  – VOLUME 1; VOLUME 2.  As far as I know, no texts with this degree of detail exist in the English language.  And remember, we always have Google Translate if you need to know roughly what’s being communicated – just type the Czech into the translation widget and cross yr fingers.

    Anyhow, just a ton of stuff to dig into and use as a springboard for your own research and/or gear-hoarding activities.  The books are quite affordable, approx.  $30 US each, and you can purchase them by writing directly to the publisher at the email address here….

    As the image above suggests, these operate exactly as you’d expect: there are separate ‘woofer’ and ‘tweeter’ elements, with a crossover at 500hz.  Although the specs are quite good, i’ve never picked these up when I had the chance…  just seems like they’ve gotta sound a little weird?  Anyone?  Anyone still using these?  How do they compare to (x)?

  • New Video: “The 4-Track In 2013” : featuring John Panos, aka KINGS

    PSV004_ImageI am v v pleased to announce that PSV #004 is now online.  “The 4-track in 2013” looks at the possibilities that an old-school cassette 4-track machine offers when used in conjunction with a digital audio workstation.  We do this through the work of John Panos, aka KINGS.  Panos’ music is some of the best new stuff I’ve heard in a while, and he has some really insightful things to say about tape noise and distortion and how these things work as both an arrangement element and a sonic frame, situating parts of the track within an historical context informed by the legacy of cassette-distributed popular music.    Check it.
