Equalizer Menu
The 8-band parametric equalizer inside SIRIUS G2.1 was designed as an effective tool to
correct room acoustics issues, especially at lower bass frequencies. We do not suggest
you use this function for changing the sonic character. Turn the rotary knob clockwise
or counter-clockwise to highlight an option, and push the rotary knob to select it.

“Y-axis Range”
: Adjust the graphic equalizer’s Y-axis range. You can choose
between 24dB and 48dB. The 24dB option gives you a display range between -
12dB and +12dB. The 48dB option shows wider range but you won’t be able to
see the fine details on frequency response curve.
•
“Enable Equalizer”
: Enable/disable the parametric equalizer.
•
“Auto Gain Adjustment”
: Allows the Lightning Streaming device to calculate and
adjust the overall equalizer gain to ensure the digital signal level does not exceed
0dBFS at any time.
We recommend you keep this option on.
•
“Overall Gain (dB)”
: When the Auto Gain Adjustment setting is disabled you may
adjust the overall gain of the parametric equalizer manually.
Please exercise
caution when utilizing this feature, and make sure that the digital level does
not exceed 0dBFS at any time by checking the frequency response curve
displayed. Failure to do so may result in significant signal distortion and damage
to your loudspeakers.
