PreSonus Acousti-Q - Manual (Page 7)

2.1.1 GAIN CONTROLS/BLENDER
The ACOUSTI-Q Gain potentiometers give the user
independent control over the amount of input signal
from the Tip (Ch.1) and Ring (Ch.2). The Blender
feature lets you change the characteristics of the ampli-
ed sound of your instrument if it is equipped with both
a mini-condenser mic and a pick-up. A variety of tonal
shadings are available by simply adjusting the relationship between the signals
from the mini-condenser mic and the pick-up.
For example, the low end of the instrument’s sound can be accentuated
by blending the mini-condenser mic level louder than the output from the
transducer (pick-up). This setting will typically result in a darker, rounder sound.
The mini-condenser microphone will reproduce the sound emanating from inside
the instrument, which will have greater bass content than the pick-up, which is
designed to reproduce the vibrations from the instrument’s body. On the other
hand, favoring the pick-up over the mini-condenser mic will result in a sound
that is brighter and punchier and will bring out the percussive qualities of the
performance. The Blender feature provides a palette of subtle tonal colors for
instruments equipped with both a mini-condenser mic and a pick-up. Feel free
to paint your sound.

the TRS connector is designed to fulll the power requirements of the internal
mini-condenser microphone and is not intended to supply the necessary current
to replace the 9V battery needed by many types of on-board preamps installed
in acoustic instruments.

Remember to turn the Master level OFF (outer Gain control fully counter-
clockwise) BEFORE the phantom power is turned ON – for instruments equipped
with mini-condenser microphones. Powering up the phantom power for the
mini-condenser mic with the Master turned up may result in VERY LOUD
feedback, which could damage your loudspeakers!
