3. Mono Outputs: 1/4" TRS jacks that deliver either an unbalanced output (use TS plugs), or a
balanced output (use TRS plugs). Follow wiring conventions as in 1 above.
4. Expand Outs: 1/4" TRS jacks connected in parallel with the Master In jacks, allowing two or
more SM26Ss to be daisy-chained for multiple splitting. Simply connect the Expand Out to the
Master In of another SM26S; there is no limit to the number of expansions possible with the
SM26S.
Note: These Expand Outputs are not buffered from the Master Inputs. Therefore, it is not possible
to mix both balanced and unbalanced lines in the same channel between several units: once the
ring and sleeve are shorted anywhere in the chain (by using a mono plug) the entire line becomes
unbalanced.
5. Mix Outputs: Balanced TRS 1/4" outputs controlled by the Master Output Level control. They
are fed either by the Master In or by any of the six Mono Inputs, or a combination of both.
Follow wiring conventions as in 1 above.
6. Universal Voltage Input: via a miniature IEC 60320 C6 appliance inlet. This mates with an IEC
60320 C5 line cord (USA domestic). Do not lift the ground connection!
Operation
Since numerous applications exist for the SM26S, no single set of operational procedures control its
use. Visit rane.com/note108.html
the many configurations of the SM26S in depth.
Internal Jumper Options
There exist within the SM26S some signal routing options, requiring removal of the top cover to move
some jumpers. This must only be done with the power off by qualified service personnel.
If an SM26S needs to have an additional set of independent outputs, as in a 2x4 stereo distribution
amplifier, the Left and Right Mix Outputs can be used in addition to the 6 Mono Outputs. Normally,
the Left and Right Mix Outputs produce the sum mix of all 6 Level and Pan controls. To break any
channel away from the Mix Output bus, internal jumpers have been provided. These are located
behind the Mix/Pan controls for each channel. J3 connects Mono Out 1 to the mix bus. J6 connects
Mono Out 2, J9 connects Mono Out 3, and so on—see the board layout diagram by visiting
rane.com.
