There are 2 major technical limits which have to be adhered to when cutting vinyl records, and, dubplates. BASS. The more loud bass there is, the further apart the grooves have to be. This means fewer grooves and less recorded time. The figure shows a section of grooves of a typical dance track, recorded at “club” volumes. The grooves are as close as you safely want them !, and gives you up to 9 minutes on a 12 inch at +6, but more like 7.5 minutes at +9. TREBLE. The speed the stylus travels across the record is faster at the outside edge, and slower towards the inside (label). The high frequency oscillations of treble can be louder at higher speeds. This is a physical fact and limitation of vinyl cutting that's been around since time began. So, you get the best and loudest possible treble towards the outside edge of the record. This is one reason we only cut 12” blanks, and, believe me the cost saving, over using a 7” or 10” blank is next to nothing, but, the quality improvement on a 12" is very, very obvious ! OTHER THINGS. THE VINYL BLANK: The blanks we use are so similar to a "factory" produced record you really can't tell the difference. They play over and over, scratch, back cue Etc. with absolutely no problems. PREPARING YOUR MASTER: We simply must have your master burnt to a CD. This is just part of the way we work, but it's no problem, and really doesn't delay things any great amount to pop it in the post. When you place your order, we will confirm the address to send your master CD to. As we use our own highly developed cutter head management electronics, we don't need you to "mono the bass" or take any other special precautions. Actually, our system mono's the bass for you (and us), automatically selecting the cut off frequency as low as possible, to maintain reasonable groove distance and protect the cutterhead. This means, that upper bass is still stereo, so, spatial stereo effects are still pretty well maintained for all but the lowest bass. It's a good idea though, to master your CD at no more than 0dB. Louder levels on CD don't mean louder volumes on vinyl!. And, too much level on a CD can cause distortion problems with the digital to audio converters in our CD playback machines. PLAYING VINYL RECORDS, AND DUB PLATES: Most DJ Cartridges have a spherical stylus tip. It’s size and shape is such that it just can not accurately “track” high volume treble. An elliptical stylus tip tracks high volume treble much much better, being closer in size and shape to the groove itself, giving a much brighter cleaner sound. While elliptical stylus cartridges are quite a lot more expensive than spherical, we think they are well and truly worth it. |  |  | |||||||||||||||||||

PLAYBACK AUDIO SPECIFICATION: Despite vinyl records technical inability to record high levels at high frequency, the two graphs show that there is actually very little difference in frequency response between a digital master, and the vinyl cut. The graphs show 30 seconds of a 2 minute "grab" from a dance tune by Faithless: The playback cartridge is the Stanton 500, which is itself "a bit shy" above 18kHz ! | |||||||||||||||||||||
