Global Parameters: Configuring Internal Default Values - SABINE Power-Q Operating Information Manual

Choose option 9 ("Global Parameters") from the Main Menu to adjust the following:
"SCREEN CONTRAST" changes the "tilt" of the front panel LCD, allowing the display to be
adjusted to optimal legibility.
"MANUAL OUTPUT LEVEL ADJUST" adjusts the signal level at the output stage of the POWER-
Q. It is adjustable in half dB increments from -32 dB to +32 dB, relative to unity gain.
"DIGITAL CLIP LEVEL" allows you to adjust the analog input level to optimize the available
dynamic range of the A/D conversion. The output level of the D/A conversion is compensated
reciprocally to preserve unity gain from the input to the output. Too high an input level will cause
clipping, and too low a level will result in noise. This parameter is adjustable from -0.05 dBu to
+31 dBu, in half dB steps. When "CLIP ADJUST" is set to "AUTO," this control is defeated.
"CLIP ADJUST" allows either manual control over the clip level (see above) or automatic control
(with Sabine's patent pending ClipGuard™). ClipGuard™ works transparently to optimize the
dynamic range of the A/D converter, preserves unity gain and increases the effective dynamic
range of the POWER-Q to over 110 dB. We highly recommend leaving the CLIP ADJUST control
set to CLIPGUARD.
"EQ FILTER WIDTH" sets the width of the graphic EQ filters as defined by the width of a filter
notch at the -3dB (half power) level. Note that the graphic EQ filters are constant-Q filters, mean-
ing their width will not change as the filter depth increases. "EQ FILTER WIDTH" is adjustable
from .5 to 1.0 octave, in .01 octave increments.
"FBX FILTER WIDTH" globally adjusts the width of fixed and dynamic automatic FBX filters. It
does not affect parametric filters. Width is adjustable from .01 to 1.00 octave, in .01 octave
increments. Narrow filters are more transparent and affect audio content less; wide filters provide
more robust feedback control and allow greater microphone mobility before feedback occurs. A
0.10 octave setting is recommended for musical performances, and a setting of 0.20 octave is
recommended for voice applications.
"FBX MAX DEPTH" globally adjusts the maximum cut an FBX filter can make. The range varies
from -80dB to -6dB, adjustable in 1dB increments.
