3DAudioInc 3DPreCD Vol.1

Этот диск будет полезен для тех, кто собирается купить преамп. Здесь представлен женский вокал с использованием различных преампов - от нескольких сотен долларов до самых дорогих!

      "Can YOU Hear the Difference?"


 The 3D PRE CD is the easiest way to hear $75,000 worth of preamps in
 your own studio. Volume 1 includes 34 preamp paths with female vocal
 and over 30 stereo samples recorded with a McPherson acoustic guitar.
 Volume 2 includes Male vocal and snare drum samples.

 On April 1 & 2, 2000, 3D Audio Inc. hosted the 3D Pre-LP (Preamp
 Listening Party) at Classic Recording in Franklin TN. We gathered as
 many mic preamps as we could fit into one room and listened to them all
 with a range of musical sources. We enlisted mic pres ranging in price
 from $130 to $8000 per stereo pair. Our goal was to determine how great
 a difference a mic preamp makes in the quality of a recording. Not only
 did we listen to 33 preamps side by side, but all the results were
 recorded and compiled onto a CD that allows engineers around the globe
 to decide for themselves whether they can hear any differences among
 these pres.


 This was a very thorough evaluation with each mic preamp level-matched
 to within .02 dB and polarity-matched to insure that the preamps were
 accurately and equally represented. (For a complete description of the
 testing setup, click here.) The listening evaluation was completely
 blind. All preamps were identified by number only until the listening
 was complete. None of the listeners had any idea which preamp they were
 hearing. Each preamp's identity was revealed only AFTER the listeners
 stated their opinion of what they heard. The sources were male and
 female voice, snare drum and stereo acoustic guitar. The microphones
 ranged from an SM-57 on snare to a Manley Reference microphone on
 female vocal. A modified C-414B-ULS (from Jim Williams, of Audio
 Upgrades) was used on male vocal and a Neumann KM-84 and Audio-Technica
 4033 were used on acoustic guitar. The 3D Pre CD, Vol. 1, features
 individually ID'd cuts of the female vocal and acoustic guitar. Volume
 2 will feature snare and male vocal.


 Technical evaluation procedures for the Pre-LP were established after
 consulting with designers Dan Kennedy of Great River, George Massenburg
 of GML, John LaGrou of Millennia Media, Greg Mackie of Mackie Systems,
 and Tim Farrant of Buzz Audio, NZ. Dan Kennedy of Great River assisted
 in supervising the testing and level matching the units. We kept the
 signal path as short as possible to minimize external circuit
 colorations. George Massenburg contributed his GML 3500 to the tests.
 John LaGrou of Millennia Media sent two preamps, solid-state and tube.
 Eve Anna Manley agreed to loan us her Manley and Langevin designs. Other
 manufacturers who sent units were Grace, dbx, Great River, Earthworks,
 Aphex, Buzz Audio-NZ, Amek, Presonus, Audio Upgrades, DW Fearn and
 Crane Song. The balance of the preamps were on loan from engineers all
 over the US.


 This was an historic event. Never has any preamp evaluation of this
 scope and depth been undertaken in the history of recording. Writers
 and editors from Audio Media, EQ, ProSound News and Tape Op are all
 covering this unique event. (Read some of what's been written so far.
 There are more stories in the works.) Representatives from AudioMedia
 magazine and ProSound News were on hand at the Pre-LP. The whole event
 was videotaped, but may never be seen due to the embarassingly stark
 honesty of the participants as they critiqued the preamps without
 knowing which was which.


 The explosive sales of inexpensive digital recorders and home recording
 has created an enormous market of people that want high quality
 recordings, but are sometimes confused about how to accomplish that,
 due to lack of experience and equipment. According to 3D Audio's owner
 Lynn Fuston, "I am frequently asked, both in person and on my web
 bulletin board Ask 3D Audio, 'what stage of recording makes the greatest
 difference in the sound?' All engineers want to know which preamp sounds
 'better, richer, fuller, brighter.' There is no way to adequately
 describe with words what a preamp can contribute to the recorded sound.
 So after 20 years of evaluating preamps on different instruments and
 vocalists myself, I decided it would be very valuable to come up with a
 way for other people, who don't have the luxury of having 5 or 10 preamps
 in the same room, to be able to hear the differences for themselves.
 That is what this listening exercise will hopefully accomplish. Can YOU
 hear the difference between a $65 preamp and $4000 preamp? Now you can
 get the 3D Pre CD and decide for yourself, in your own studio on your
 own monitors."
