Swiss Army Mixer-7
6-to-1-to-6 Mixer Splitter
Figure 9 shows how to use two SM26S’s to
create a 6‑to‑1 mix then a 1‑to‑6 splitter,
to drive the six channels of two MA 3 am‑
plifiers. In just six rack spaces, this con‑
figuration creates a complete six‑channel
mixer zone amplifier system.
The controls of the first SM26S are used to condition
and mix the six Mono Input signals while the controls
of the second SM26S are used to set the individual
Levels of the six amplifiers.
4-Channel Stereo Splitter
Don’t get into the mind trap of thinking of the SM26S
as only a mono splitter mixer. It can function equally
well as a stereo splitter mixer. Figure 10 shows how
to configure the SM26S as a 4‑channel stereo splitter.
The stereo Input pair is brought into the Left and Right
INPUT jacks and then routed via the MIX pots to all of
the Outputs. By setting Channels 1, 3 and 5 for full Left
mix and channels 2, 4 and 6 for full Right mix, you split
the incoming signal into 3 stereo output pairs available
from OUTS 1 & 2, 3 & 4, and 5 & 6 respectively. The
4th stereo Output pair is taken from the Left and Right
MIX OUTPUT jacks as shown. (Note: use of the 4th
independent stereo output requires an internal jumper
modification.)
Stereo mixing is done in the exact opposite man‑
ner. Up to 4 stereo pairs are brought into all Inputs
by connecting one pair to the Left and Right INPUT
jacks and the three remaining “lefts” to Channels 1,
3 and 5, and the “rights” to Channels 2, 4 and 6. Now
by rotating all odd PAN pots fully CCW(Left) and all
even PANs fully CW(Right), you have mixed all 4 pairs
down to 1 master pair available at the Left and Right
MIX OUTPUTs.
Guitar Racks
Figures 11‑13 show three possible ways to connect a
guitar amp to multiple effects. Figure 11 involves buy‑
ing or building a cable that parallels all of the inputs
of the effects so one loop output drives them all. This
works and should cause no great difficulty if the output
impedance of the amplifier loop is low. Outputs of 1k
ohms or less should be able to drive as many effects de‑
vices as you would ever want. A second amplifier could
be used from the other Mix Output of the SM26S for
stereo.
