*Lexicon 224 & EMT 250 Note
The EMT 250 and Lexicon 224 anti-aliasing filters for their A/D and D/A conversion are not linear-phase
filters; therefore the emulations do not have a latency that is the same at all frequencies. Thus, we cannot
report to the delay compensation engines a delay that is correct for all frequencies. The reported values are
good at low frequencies, but become off at high frequencies.
For example, when the EMT 250 plug-in is in Delay program mode and set with zero delay time and pre-
delay values, the plug-in output will not be completely cancelled 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 plug-in is bypassed via the EMT 250 Power switch, do not have this
issue and will be fully compensated by the Reatime Rack software.
