JH 16 machines:

Until I finish this page, if you go to the AMPEX AUDIO ALIGNMENT page the alignment procedures there are almost EXACTLY like the MCI JH-16's Audio Alignment.

Note that MCI in the JH-16 series machines used 'copies' of the Ampex Audio Cards, so the alignment for Reproduce, Record and Bias are exactly the same.

Only the Level pots are different: in the MCI JH-16 they're in the Input/Output Switching module. Note that in the MCI Record Card the 'Input Level" pot is in the Audio I/O Switcher card and NOT in the Record Card as with the Ampex Record Cards.

I'm working on a detailed Audio Alignment Procedure for the MCI JH-16. Once that's finished I'll put up right here...

These machines are different from the JH-16 series in that the Record Card now has the Sync functions on it as well as the Record functions. They've got more ICs in the Audio Circuit than the JH-16 series machines. Personally I think the fewer ICs in the Audio Path the better the overall sound...

the 'theory' of alignment is still similar to the Ampex Audio Alignment procedures, so go take a look there first...

The JH24 AUDIO alignment from the Manual  (as well as the Transport Alignment and Trouble-Shooting tips)  is now up in the Manuals Link on the Main Page
