1.2 FEATURES
The following is a summary of your ACOUSTI-Q’s features:
Dual Input Stage
Your ACOUSTI-Q contains two separate dual servo preamps with separate
volume controls. This award-winning design provides ultra low noise perfor-
mance and wide dynamic control for both preamps giving the ACOUSTI-Q the
ability to boost the desirable signals without increasing unwanted background
noise
Blender Control
Separate volume controls are provided for mixing the input signals. This is
accomplished by way of a dual concentric volume control for blending incoming
signals to the 1⁄4” TRS input jack.
12AX7 Tube
The input signal is routed through a 12AX7 vacuum tube after the Master
output. This design applies the aural enhancement capabilities of the tube on
the input while minimizing unwanted audio artifacts.
12V Phantom Power
The ACOUSTI-Q has +12VDC Phantom power available to the Ring of the 1⁄4”
TRS input. When the Phantom power switch is engaged, +12VDC power is
supplied for use by mini-condenser microphones installed in some acoustic
instruments.
Use caution when engaging the Phantom power switch as a loud transient
may occur.
Phase
A phase reverse switch is provided to enable the user to invert the phase of the
input signal. Engaging the phase switch can compensate for different connector
hook-ups. Varying the signal’s phase may also be used to achieve an intentional
‘out-of-phase’ sound. Experiment!
Notch Filter
The ACOUSTI-Q has a Notch lter on the front panel for isolating and controlling
low frequencies that may be prone to feedback.
