The AD-16 was an integrated telephone autocoupler
and DTMF controller that was designed to
provide telephone control for studio equipment.
The line of AD-16s was produced from 1991
to 1996 when it was replaced by a far more
powerful product, the DR-10.
If you have an AD-16, it's made of an AC-2
autocoupler combined with a DTMF-16 touchtone decoder. The AD-16 may also
have something called a ComboLok. This was
an optional board that provided password
security for the AD-16. There
were several versions of the ComboLok made.
The last version of the ComboLok for AD-16s
was 1.6. You
can download that manual here. If your ComboLok is made on an
unsilkscreened PCB that mounts upside down
to the top cover of the AD-16,
probably a version 1.2. Version 1.2 devices set the combinations
by moving four colored wires to different
pins that correspond to the DTMF tones.
You can also download the retrofit
instructions that show how the ComboLok 1.6
connects to the AD-16 here.
If you're trying to recompile a
lost book, you will need the sections for the AC-2,
and the front
information on current products is available
on this site.
