Front Panel Description
1
MASTER INPUT LEVEL
sets the gain of the Left & Right Master Input stages, with a range of Off to +12 dB. In the splitting
mode, this controls the Level of all Mono channel Outputs at once (i.e., those which do not have a separate input).
2
Mono Input LEVEL
controls the Level of signal through each particular channel. When fed from the MONO INPUT jack,
each stage has a gain range from Off to +12 dB minimum, allowing level matching of -10 dBV equipment to +4 dBu gear. When
fed via the LEFT & RIGHT MASTER IN, these LEVEL controls automatically limit to a maximum of unity gain to accommo-
date the +12 dB available from the Left & Right Input gain stages.
3
MIX / PAN
serves two different functions:
MIX
: When used as a SPLITTER, this controls the mix of Left and Right Master Input program to each channel’s MONO
OUT.
PAN
: When used as a MIXER, this control pans the Mono channel Input between the LEFT and RIGHT MIX OUTPUTS.
4
MASTER OUTPUT LEVEL
controls the gain of the output stages and the amount of signal at the MIX OUTPUT jacks. It
does not affect the level of any of the six MONO OUTPUTs. This allows an increase in headroom to eliminate overloading due to
excessive combined signal from one or more Inputs. Range of gain is from Off to 0 dB (unity). Refer to the block diagram below.

POWER indicator:
When this yellow LED is
lit
, the SM26S is ready to go (when it’s off, it’s not).
