OVERVIEW 1
Equalizer
The ACOUSTI-Q Equalizer section has a pair of dual concentric potentiometers. 
The left inner control is a sweepable Mid-Range control and allows the user to 
select a frequency from 250Hz to 5kHz while the left outer control cuts/boosts 
the selected frequency +/- 12dB. The right side inner control, which is labeled 
Brilliance, boosts or cuts (+/- 12dB) 8kHz and above while the outer left side 
control in the Equalizer section, which is labeled Bass, boosts or cuts (+/- 12dB) 
100Hz and below.
Master Section
The Master section of the ACOUSTI-Q contains a Mute switch and a dual 
concentric control for use in setting the level of the Main output and the level of 
the Cut/Boost feature*. The Mute feature is provided for use in conjunction with 
an external tuner. Engaging this switch mutes the Main output while allowing 
the signal to remain present at the -20dB AMP/TUNER output.
*Activation of the Volume Cut/Boost feature requires use of an optional external 
footswitch which also provides footswitch operation of the Mute function. The 
footswitch may be purchased at your authorized PreSonus Dealer.
