VOLUME CONTROL
Controlling volume in the Boulder 2010 Preamplifier can be easily
set to your preference for scale and resolution over its 1,000 step, 100 dB
range.
From “PROGRAM MODE” press the DISPLAY pushbutton. “VOL
SCALE?” will show in the left display, and “-100 TO 0” will show in the
right display.
Rotating the center control will change the lowest setting now shown
to a maximum of “0 TO 100” or anywhere in between. This feature
allows you to have the scale of your choice. One possibility would be to
set the scale to “-80 TO 20” thus indicating the true gain and attenuation
of the Boulder 2010 Preamplifier.
Once you have chosen your scale, press the DISPLAY pushbutton
again. “RESOLUTION?” will show in the left display, and “0.1dB/
STEP” will show in the right display. Rotate the center control to select
0.1, 0.5, or 1.0 dB per step as displayed in the right display. Then press
the DISPLAY pushbutton again.
