1. Master Input Level: Sets the gain of the Left & Right Master Input stages, with a range of Off to
+12 dB . In the splitting mode, this controls the Level of all Mono Channel Outputs at once (i.e.,
those which do not have a separate input).
2. Mono Input Level: Controls the Level of signal through each particular channel. When fed from
the Mono Input jack, each stage has a gain range from Off to +12 dB minimum, allowing level
matching of -10 dBV equipment to +4 dBu gear. When fed via the Left & Right Master In , these
Level controls automatically limit to a maximum of unity gain to accommodate the +12 dB
available from the Left & Right Input gain stages.
3. Mix / Pan: Serves two different functions:
Mix : When used as a splitter, this controls the mix of Left and Right Master Input program to each
channel’s Mono Output .
Pan : When used as a mixer, this control pans the Mono Channel Input between the Left and Right
Mix Outputs .
4. Master Output Level: Controls the gain of the output stages and the amount of signal at the Mix
Output jacks. It does not affect the level of any of the six Mono Outputs . This allows an increase
in headroom to eliminate overloading due to excessive combined signal from one or more Inputs.
Range of gain is from
Off to 0 dB (unity) (refer to the Block Diagram in the Appendix ).
5. Power Indicator: When this yellow LED is lit , the SM26S is ready to go (when it’s off, it’s not).

All Inputs and Outputs are Balanced: Tip = positive (+), Ring = Negative (–), Sleeve = Chassis Ground.
All audio jacks are Class 2 wiring.

1. Master In: These balanced Tip-Ring-Sleeve (TRS) 1/4" Master Inputs feed all six Mono Outputs
when all Mono Inputs are not used. Connecting to an individual Mono Input disconnects that
channel from these Inputs (refer to the Block Diagram in the Appendix ).
For unbalanced operation use a standard mono 1/4" plug; for balanced operation use a TRS
(stereo) 1/4" plug wired as follows:
• Tip is (connect to pin 2 on a 3-pin connector).
• Ring is signal – (pin 3 in a 3-pin connector).
• Sleeve is chassis ground.
2. Mono Inputs: 1/4" TRS jacks which accept either balanced or unbalanced mono signals. These
are switching jacks which automatically bypass the Master In jacks whenever a plug is inserted
(refer to the Block Diagram in the Appendix ). Follow wiring conventions as in 1 above.
