Compensating for Pultec EQ
The UAD Pultec and UAD Pultec-Pro equalizers use an internal sample rate of
192kHz to achieve their magic quality. This upsampling results in a slightly
larger latency than other UAD plugins. Therefore, they require slightly more
compensation to remain perfectly synchronized with other tracks. Specifi-
cally, they require an extra 13 samples of compensation when the session
sample rate is below 100kHz.
Therefore, when using the DelayComp or TrackAdv plugin to manually com-
pensate for a Pultec EQ, enter a Samples value of 13 (in addition to the ap-
propriate “Plugs” value) for each instance of Pultec and Pultec-Pro. The key-
board shortcuts PageUp/PageDown and Shift+Arrow automatically add the
13-sample Pultec value for your convenience.
Important: Compensating for Pultec and Pultec-Pro is not required if the
host application supports full plugin delay compensation throughout the sig-
nal path, or when it is used only on the outputs. See “Host PDC Implementa-
tion” on page 46.
Note: When running audio at or above 100kHz resolution, no Pultec upsam-
pling is performed. In this case, leave the Samples value at zero.
Pultec
Group/Bus
Example
Situation: You have a song with bass, drums, guitar, and 2 vocal tracks. You
want a fat, warm vocal blend so you put both vocal tracks on a group/bus
and apply one instance of Pultec EQ to the vocal bus. Result: The vocal tracks
play late in relation to the instrument tracks.
Solution: Send the output of the unprocessed instrument tracks (but not the vo-
cal tracks or the Pultec return) to a different group/bus, and put one Delay-
Comp with a Plugs value of 1 and a Samples value of 13 on this group/bus
that contains the dry non-vocal tracks. If you put 2 Pultec EQ’s stacked in se-
ries on the vocal bus, the unprocessed bus DelayComp Plugin value would be
2, and the Samples value would be 26.
Note: UAD Pultec-Pro only requires one compensation per instance. For ex-
ample, if using both MEQ-5 and EQP-1A within a single Pultec-Pro, only one
instance compensation is required.
