Rane SM82S Stereo Line Mixer

Rane SM 82S Stereo Line Mixer

The Rane SM 82S is a product offering incredible power and versatility. It is the equivalent of a sixteen channel mixer in one rack space. Measuring only 5.25 inches deep, it can do the job of mixers costing several times as much while only occupying a fraction of the rack space. It is ideally suited for keyboards, synthesizer expander modules and drum machines, as well as such things as effects mixing in guitar racks. It also functions as an excellent submixer for stereo line inputs and effects to a larger console. Because of shorter internal signal paths, it is much cleaner than many mixers ten times the cost and size.

Each of the eight Stereo (two channel) input channels feature a stereo rotary input Level control, a stereo aux Send level control slider and a left to right Balance control slider. When a single mono input is used, the Balance control acts as a pan pot. The aux return section provides a rotary Return Level control and a slide control for left to right Balance. The output stage includes a rotary Output Level control and a slide control for left to right Balance.

The human engineering applied to the SM 82S makes it extremely easy to operate. The segregation of function between rotary and slide controls (rotary for all input and output Levels and slide for Balance and Send) makes it simple to use, even in the dark.

The SM 82S is expandable using the 1/4″ TRS Main Expand Input and Output jacks. Expansion is as simple as connecting a stereo 1/4″ jumper cable from the first unit’s Expand Output jack to the second unit’s Expand Input jack. Now, two SM 82S units create a 16 channel stereo (32 input) line level Mixer in just two rack spaces. Or, 24 channel stereo (48 input) Mixer in just three rack spaces. You get the idea!

One of the most unusual features of the SM 82S is its inherent immunity from noise. All eight of the stereo inputs may be turned all the way up without increasing the internal noise of the mixer. This is critical due to the wide variation in output levels found in musical instruments and tape devices. A fairly low-level guitar may be combined in the same system with a high level synthesizer without any undesirable side-effects. The SM 82S eliminates the concerns normally associated with mixing so-called -l0 dBV units with +4 dBu types.    Features:    Specifications:
