and right channels of a stereo signal. Also, only one record device
is shown. The small circles with a letter inside correspond be-
tween the Mixer Diagram and the Block Diagram. For example,
referring to the SX-36 diagrams, the Line In On/Off control, la-
beled “G” in the Mixer Diagram, is showing that when this control
is “On”, the selector switch in the Block Diagram is in the “G” po-
sition. In case you are not familiar with some of the symbols
used, the triangles with the + and – inside are amplifiers. It is only
important to understand that the Trim controls change the gain of
the amplifier circuits. The circles with the Greek “E” inside are
summing nodes. This means that all signals pointing with arrows
to the circle are combined at this point into one signal.

Input Trim Control A determines the level of input signal at which
clipping occurs. If set to +8, the maximum signal which can be
input is +8 dBu, without being clipped by the A/D converter. This
applies to having the record source set to G or I. If the record
source is set to J, Line Out, a hotter signal may be input into the
card and then attenuated with sliders C or E. This will be dis-
cussed in more detail below.
Output Trim Control B determines the level of the output signal on
Line Out which corresponds to digital clipping. If the control is set
to +8, the maximum output signal level is +8 dBu. If the control is
set to +20, the maximum output signal level is +20dBu. Note that
these signal levels correspond to balanced outputs. If the outputs
are wired as unbalanced, see the table in the section on “Bal-
anced and Unbalanced Signals” to determine the actual output
signal level.
Attenuators C, D, and E control analog feed-through levels. Slider
C controls the level of the signal on Line In which is fed-through to
the Line Out. Slider D controls the level of the Mic Input which is
fed-through to Line Out. Slider E controls the level of the Aux In-
put which is fed-through to the Line Out.
