CMDM
Cross Modulation Distortion Meter Cross Modulation Distortion Meter

The CMDM serves as cross-modulation analyser for the fast and easy determining of the correct exposure of stereo sound tracks on negative or print film

As compared with other systems the CMDM neither requires a reference (i.g.400 Hz) nor the appropriate level adjustment.
The CMDM can be used for almost all existing cross modulation signals.
It enables the simultaneous two channel measurement of a cross-modulation signal (f1/f2) within a frequency range of 4 kHz to 16 kHz at a difference frequency (f2-f1)

The CMDM measures the cross-modulation distortion with reference to the measured level of the cross-mode signal (similar to different tone measurement according to DIN 45 403 or IEC 468-3).

It displays in percent (%) distortion with a +(plus) sign indicating that the level is over exposed and a – (minus) sign indicating that the the negative is under exposed.

The unit is small, portable and can be easily connected via a combined XLR/Jack input connector.
