Manual Calibration Procedure
Manual calibration tools are provided so expert users can calibrate the sys-
tem to their preferred methods for obtaining desired results. For example,
some technicians may prefer adjustments for lowest distortion at a certain fre-
quency; setting bias for maximum sensitivity (instead of overbiasing); or other
non-standard techniques.
The calibration procedure described here is the most commonly used tech-
nique, and is the (albeit simplified) method recommended by the Ampex Op-
eration and Service Manual.
Important:
Manual calibration is not required to use UAD Ampex ATR-102.
Following this procedure will result in the same (or nearly the same) values ob-
tained by simply using the
feature.
Tip:
When making manual calibration settings, consider disabling Auto Cal
so the manually calibrated values are not accidentally lost if any of the con-
trols that force automatic calibration (Tape Type, Tape Speed, Emphasis EQ,
and Head Width) are inadvertently modified.

unless audio is present on the track containing the plug-in and the transport is
running. Placing the plug-in on an aux, bus, or master output may eliminate
this host limitation.
