xEM - the perfect SPEM companion

>>> Propellerhead Shop

xEM is a Peak, RMS or Dynamic Range stereo metering for 4 channels, one main input and one main output.

It adds two labels for each channel.

It can be used alone for metering up to 6 tracks.

It is the perfect companion of SPEM (Serial Parallel Effects Mixer rack extension) : it adds stereo metering and labels to SPEM.

With adding xEM to SPEM you can have two different metering modes at the same time and get detailed labels. Or, in folded mode, you add just half 1U rack height and get labels.
