General Description
The Rane SM 82 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 82 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 82 is fully expandable using the ¼" TRS Main Expand Input and Output jacks. Expansion is as simple as connecting a stereo ¼" jumper cable from the first unit’s Expand Output
jack to the second unit’s Expand Input jack. Now, two SM 82
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!

Application Information
The SM 82 allows you to mix eight Stereo line level Inputs
down to a main Stereo Output. Additionally you can create a
separate Stereo Loop Send mix for driving any stereo, or mono,
external processor, and then return from this processor into the
Stereo Loop Return Inputs. The stereo Return Level control is
used to set the desired mix of wet and dry signals.
For applications not requiring the looping facilities, the Loop
Return Inputs double as a fully functional 9th Stereo Input,
creating a 9-Input Stereo Mixer! When used this way, the Loop
Send Outputs become a separate Stereo Output pair, useful for
monitor sends, tape outputs, or any other application.
When not used for expansion, the Main Expand Output pair
double as a pre-fader stereo mix, again useful as tape outputs, or
any other fixed-level application.
Mono sources and external processors are handled easily by
the SM 82. Connecting only to any Left Input Jack automatically routes this signal to the Right channel so an equal Left/Right
signal is summed into the mains. Similarly, connecting only to
the Left Loop Send output gives you an equal mono L+R output
send for mono input processors.
The question arises regarding mic levels. Since the SM 82
operates only at line levels, microphone applications require separate boosting before connection. Rane offers a mic stage model
MS 1b ideally suited to this application.
