Consumer Electronics Show
Las Vegas - January 8, 2004
Ray Kimber, of KIMBER KABLE, will be demonstrating the latest IsoMike� recordings in the Alexis Park, room # 1512 (the DiAural Exhibit Room). The playback source will be Direct Stream Digital (DSD) tape at 2.8224MHz, via an EMM DAC (www.emmlabs.com).

The IsoMike� is an acoustic baffle that is placed between two spaced omnidirectional microphones. Unlike previous baffles, the IsoMike� is much larger, magnitudes more absorptive and has a shape that improves the low frequency isolation by "scattered phase." (Arrows point to microphones)

LATE BREAKING NEWS
There will also be limited playback of experimental unprocessed 4 channel DSD audio. This was recorded with a 4 mic/4 baffle IsoMike� array, using our brand new Genex 9000 DSD hard disk recorder (www.genexaudio.com). This is also the first IsoMike� recording using our new EMM ADAC and a new custom Millenia Media pre-amp (www.mil-media.com).

(The LF and LR mics are shown by arrows, the RF and RR mics are blocked from view by the IsoMike�.)

Playback, speakers will be using the very latest version of DiAural� crossovers, finished 3 days ago. Getting ready for CES is like track and field, sprinting "down to the wire!" The recordings and playback have no mixing, limiting, compression or any other type of processing. You can be assured of a demonstration that will stand out of the crowd.

The recordings were made at Weber State University, Ogden, Utah. Featuring WSU Faculty, Students, and Guests in several different musical settings, both live and session. (www.weber.edu) GO WILDCATS!!

Notes about the recordings:

Tracks are recorded using only two microphones, however, up to 4 recorders running in-sync, allowed us to use two, three or four pairs of microphones and later compare the differences between them. The distance from the microphones to the nearest performer was usually more than 25 feet. However, for a few of the tracks with a small number of performers the distance could be as close as 15 feet. Microphones owned by KIMBER KABLE include: Neumann M-150, TLM-50, TLM-170, DPA 3529A, 4003, 4007, 4004, Sennheiser MKH-800, MKH-20, Earthworks QTC1, and B.L.U.E. BOTTLE w/B4-B6-B7. Some view the addiction to buying microphones as a sickness, I think of it as buying precious metal. (www.neumannusa.com, www.sennheiser.com, www.earthwks.com, www.bluemic.com, www.dpamicrophones.com) Recording system used custom KIMBER KABLE silver microphone cables, KK Select interconnects and KK Palladian Power cables.

The recordings were made with Tascam DS-D98 HR recorders (www.tascam.com). The recordings were then transferred to a Pyramix Mastering System (www.merging.com) for edit selection. No gain changes or processing was done, so some tracks will be of a softer or louder level than other tracks. However, the dynamic range within a track is the same range as the original live performance. All recordings were made at a low enough level to assure no clipping, therefore you may need to turn your volume control a bit higher than when playing commercially available CDs which have had their volume "normalized" and/or compressed. Use caution on first playback as some of the tracks do nearly reach 0VU, tracks 19 and 20, for example might scare the cats.

The DSD tapes will only play in a Tascam DS-D98HR tape recorder. If you use the internal DAC converters you may want to experiment with changing the filter setting in Menu #D to "custom" instead of "standard." Super high performance will be obtained by using a high quality external DAC that will convert SDIF-3, such as the Ed Meitner EMM DAC. Hint: use the EMM as the clock source. All DSD recordings have highband noise, this might cause audible "sparklies" at high volume settings on playback. Nothing is broken, this is the normal result of playing raw DSD, mastered DSD material will have filtered the 80KHz noise, call if this happens when playing the DSD tapes.

The CDRs are Redbook 44.1KHz/16bit down-converted from DSD, playable in a normal CD player.
