Are all Nagras Crystal Sync?
24fps-25fps
I was recently doing sound postproduction for the movie done with 16mm
camera. the movie has been transferred on beta tape, than edited in PC
computer PAL (which means 25fps).
When I finished I transferred soundtrack on the TASCAM DA 20 and sent it
to the laboratory.
for editing and 35mm blow up. Because of the frame difference the sound was
slightly (but noticeably) pitched down.
Is there any way to avoid this without using expensive sync equipment?

Are all Nagra 4.2's crystal? My assumption is that they are, but it seems prices vary so much (I know that's related to condition and such). Can you tell me anything about the differences between Nagra 4.2, 4, and 4L?
Almost all 4.2's are crystal, although once in a blue moon or so it is possible to encounter a 4.2 that does not have the crystal sync board.
(rare) The IV-L model came between the Nagra III and the recent 4.2. Outwardly, the IV-L is very similar to the 4.2, and features two mic inputs
plus a third (line) input knob on the face. Record and sync wise, the IV-L is identical to the 4.2 There are a couple of minor cosmetic differences, but nothing difficult to figure out. The main difference with the IV-L is that it was a period of transition and experimentation regarding the mounting of the head stack. Some IV-L's will lose their head alignment easily; others are as rock solid as the 4.2 It is best to have an experienced Nagra tech check out any IV-L, to confirm that the head alignment is not prone to drift. I have written a booklet on the operation of the Nagra 4.2, which discusses the differences with the IV-L, called the "Guide to the Nagra 4.2" which we sell for $6.00.
