Chapter 4 Operation Section
The dual Synth Trim Control simultaneously adjusts the gain (level) of 
the left and right channel inputs. Its normal operating or starting 
position is when set fully counterclockwise. In order to help maintain 
the extremely high frequency response and low noise characteristics of 
the Model SSM, utilize this control only as needed. 
 
If an individual synth or sampler proves too weak, it is good practice to 
add level by first pushing up the channel's slide fader if possible, or by 
making sure that the synth or sampler plugged into that channel is set to 
its maximum output. Should these adjustments fall short, then turn the 
Synth Trim Control clockwise until the required mixing level is 
obtained. Repeat this procedure each time a new patch, or sample is 
chosen. 
 
 
The equalization section has two independent signal paths and utilize 
dual pots that simultaneously adjust the left and right parameters of the 
equalizer. 
 
The equalizer for the SSM is a semi-parametric type, whereas the 
Frequency Sweep Control adjusts one of the parameters, and the Boost/
Cut Control adjusts the second of the parameters. The third possible 
parameter available on a parametric equalizer would be the frequency 
bandwidth adjustment. The bandwidth (Q) for the low, mid, and high 
bands on the SSM equalizer are fixed at approximately 12db/octave. 
 
This control provides 15db of bell shaped Boost or Cut for the high 
frequency range (5K to 15Khz), and is used in conjunction with the 
High Frequency Sweep Control (see below). 0db boost/cut (flat) is 
obtained when this control is set to its center position. 
 
The High Frequency Sweep Control is used in conjunction with the 
High Boost/Cut Control and provides continuous adjustment from 5Khz 
(fully counterclockwise) to 15Khz (fully clockwise). 
 
This control provides 15db of bell shaped Boost or Cut in either the low 
band (50 to 500hz) or mid band (500hz to 5khz) frequency ranges 
dependent on the position of the Low/Mid Band Select Switch (see 
below). This control is used in conjunction with the Low/Mid Sweep 
Control. 0db boost/cut (flat) is obtained when this control is set to its 
center position.
