Rear Panel Description SM26S 100-240 V 50/60 Hz 7 WATTS COMMERCIAL AUDIO EQUIPMENT 24TJ R LEFT 6 RIGHT RANE CORP. MADE IN U.S.A. ACN 001 345 482 MIX OUTPUT 6 5 5 4 3 2 MONO OUTPUTS 3 LEFT ALL INPUTS AND OUTPUTS ARE BALANCED: TIP = POS(+), RING = NEG(-), SLEEVE = CHASSIS GROUND 1 6 5 4 3 2 1 RIGHT EXPAND OUT MASTER IN MONO INPUTS 41 2 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 signal + (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 1 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 1 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 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! Manual-3
