UAD Powered Plug-Ins Manual - 55 - Using UAD Powered Plug-Ins

Compensating for Pultec and Pultec-Pro

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 50.

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.
