Rear Panel Description

1

 MASTER IN

 are balanced Tip-Ring-Sleeve (TRS) ¼" Master Inputs. These Inputs feed all six MONO OUTs when all MONO 

INs are not used. Connecting to individual MONO INs disconnects that channel from these Inputs (refer to the Block Diagram). 

For unbalanced operation use a standard mono ¼" plug; for balanced operation use a TRS (stereo) ¼" 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

 are TRS ¼" 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 (see the Block Diagram). Same wiring conventions as in 

above.

3

 MONO OUTPUTS

 are ¼" TRS jacks that deliver either an unbalanced output (use TS plugs), or a balanced output (use TRS 

plugs). Follow wiring conventions as in 

above.

4

 EXPAND OUTS

 are ¼" TRS jacks connected in parallel with the MASTER IN jacks, allowing two or more SM26Ss to be 

daisychained 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

 are balanced TRS ¼" 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 (see 

The Swiss Army Mixer 

RaneNote). Follow 

wiring conventions as in 

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!

SM26S

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

All audio jacks are Class 2 wiring.
