Figure 13. Mono Guitar Effects Splitter/Mixer

Many effects have mono inputs and stereo outputs. 

In this case, connect the left and right outputs of Effect 

1 to MONO IN CHANNELS 1 and 2 of the SM 26B 

respectively. Rotate the MIX/PAN control of Channel 

1 all the way to the Left and the MIX/PAN of Chan‑

nel 2 all the way to the Right. This preserves the mix of 

the effects’ stereo output and passes it to the LEFT & 

RIGHT MIX OUTPUTs of the SM 26B. Continue with 

Channels 3 & 4 for the second effect and Channels 5 & 

6 for the last effect. Set the Channel LEVEL pairs to the 

same levels to preserve the intended mix of the stereo 

effect.

The best way, shown in figure 12, uses one SM 26B 

as a splitter to actively split the signal into as many 

as six separate feeds (or three stereo) for the effects 

inputs. To mix all of the effects outputs back together, a 

second SM 26B connected as a mixer could be enough 

Inputs for a mono system, or an SM 82 with 

eight

 

stereo

 

Inputs works great for a stereo system. 

Now here's a way to 

split and mix with one SM 26B

shown in Figure 13. From the loop output going to 

the LEFT INPUT, Channels 1,2 and 3 will act as the 

splitter

, with their pan controls all the way to the left 

bus. Since the MONO IN jacks 

know

 that an individual 

Input overrides the master Input…Channels 4,5 and 

6 will act as the 

mixer, 

with their pan controls all the 

way to the right. The RIGHT MIX OUTPUT returns 

signal to the amplifier. Cool!

DJ Effects Mixer

DJ mixers have stereo sends and returns, but it’s just 

as easy to use the SM 26B to combine 3 stereo effects 

(or an SM 82 for 8 stereo effects). The concept is the 

same as the Guitar Rack in Figure 11, but in stereo. See 

Figure 14.

And More

The range of applications of the Model SM 26B Split‑

ter Mixer is staggering and have been barely touched 

in this RaneNote. From simple sub‑mixing to complex 

split‑mix combinations, to individual equipment signal 

conditioning, to line splitting, to your unique applica‑

tion, the list of uses for the SM 26B goes on and on. 

Experiment and have fun!
