UAD System Manual - 88 - Chapter 9: UAD Delay Compensation

Upsampling Values Table

Table 7 lists the additional latency produced by upsampled UAD plug-ins.

*EMT 250 Note The EMT 250's anti-aliasing filters for its A/D and D/A conversion are not lin-

ear-phase filters; therefore our emulation does not have a latency that is the

same at all frequencies. Thus, we cannot report to the delay compensation en-

gines a delay that is correct for all frequencies. The value we report is good

at low frequencies, but becomes off at high frequencies.

For example, when the plug-in is in Delay program mode and set with zero

delay time and predelay values, the plug-in output will not be completely can-

celled when mixing with flipped phase against an unprocessed track; high

frequencies will leak through. However, the latency through the dry side of the

wet/dry mix, and the latency when the plugin is bypassed via the EMT 250

Power switch, do not have this issue and will be fully compensated by the

DAW.
