5.5 | Correlator
The Correlator instrument displays the phase relationship between the
two channels of a stereo signal and thus its mono compatibility.
Identical signals in both channels have a correlation of +1; completely
unrelated signals have a correlation of 0. Normal stereo mixes mostly
show correlation values between 0.3 and 0.7. When both channels carry
identical signals but one channel‘s polarity is switched (180° phase), the
correlation will be –1.
When using the Correlator, please ensure that the display does not read
negative values (shown in red) across extended periods.
Factory presets using the Correlator instrument:
• 2CH SDI ATSC LRA+CORR
• 2CH SDI EBU LRA+CORR
• 3 X 2CH SDI ATSC
• 3 X 2CH SDI EBU
Example: Correlation is b0,3 to +0,7
