SM26S

SPLITTER MIXER

Data Sheet-1

General Description

The Rane Model SM26S Splitter Mixer is one of the most useful, 

yet unusual audio products available. In its most basic configura-

tion, it is a six-to-two line level mixer. It will accept six balanced 

or unbalanced line level inputs which are applied to six Level and 

Pan controls. An additional stereo Master Input allows a total of 

eight inputs. The result of the mix is sent to an overall Master 

Output Level control and appears at the Left and Right Outputs 

on the rear. In its splitter mode, the SM26S can take one or two 

line level inputs and split these to any of the six Mono Outputs 

on the rear. The Mix/Pan controls in this mode control the level 

from each of the two input buses to be applied to each Output. 

Internal header blocks allow the Mix Outputs to become an 

independent stereo out, allowing a total of eight outputs. The 

SM26S may also be used as a six input, six output buffer ampli-

fier in which case signal applied to Input 1 is delivered to Output 

1, and so on.

The SM26S may also be used in a combination of modes at once. 

For instance, Inputs 1 through 3 may be mixed to the left and/

or right output buses while at the same time Outputs 4 and 5 are 

delivering signal originally applied to the Left and Right Master 

Inputs while at the same time Output 6 is being driven from 

Input 6 in the straight through mode.

The front of the SM26S comprises a Master Input Level 

control, six Channel Level controls, six Mix/Pan controls and a 

Master Output Level control. The rear of the SM26S provides 

two Master Left and Right Inputs, six Mono Inputs, six Mono 

Outputs and two Master Left and Right Mix Outputs. All Inputs 

and Outputs on the SM26S are ¼" TRS active balanced.

See the RaneNote, 

“The SM26S Swiss Army Mixer”

tional application information, available from our website.
