ALM Busy Circuits Stereo Sum

An ever-valuable utility in an increasingly stereo-centric Eurorack space, ALM's Stereo Sum is a unity gain mixer adept at combining multiple stereo signal paths into a centralized mix. Divided into two mixing sections, Stereo Sum features two Left and Right inputs per mixer, along with a Left and Right output. Should you need to mix more than two stereo sources, leave the top output pair unpatched to cascade down into the lower section for a four-channel stereo mixer. Blend your stereo samplers and oscillators or sum multiple spatialized effects chains with Stereo Sum.

Introducing STEREO SUM - ALM038
The ‘STEREO SUM’ is a unity gain summing mixer that features four stereo input pairs summed as pairs to two independent mix outs or all as a single combined mix. It is a useful utility for efficiently combining outputs of multiple stereo sources, such as the MEGA-TANG and Jumble Henge mixers or multiple MFX returns.

The inputs accept stereo or mono signals (via normalisation) which can be audio or CV (module is DC coupled) and the top mixer’s outputs are normalised to the bottom mixer section meaning if the upper output is left unpatched the two upper inputs will be added to the lower output.
