Figure 4 shows how the SM 26B can be used

as a “straight through” line buffer amplifier. In‑

exit from the MONO OUT jacks. Each channel

has a se12dB gain stage with LEVEL

control.

NOTE: One additional channel can be

gained by rotating all the PAN pots fully CW

and using the LEFT INPUT and LEFT MIX

OUTPUT (or rotate tully CCW and use the

RIGHT IN and OUT combination).
