c a n p roduce while the patented STRING DYNAM-
ICS filter minimizes tonal contrast appare n t
between high/low volume levels. The micro p h o n e
channel supplied with phantom power, accepts two
types of input, balanced XLR for low-impedance
m i c rophones and 1/4 inch TRS (Ti p - R i n g - S l e e v e ) ,
for balanced or unbalanced, high-impedance
m i c rophones or line-level equipment. Front panel
A U X I L I A RY jacks can be used to plug in re c o rd e d
MIC - LINE/INST CHANNEL - (Items 14-22)
14.MIC - Plug your microphone in here. This three pin XLR
balanced female input connector is intended for low-
impedance microphones.
15.LINE/INST - This 1/4 inch, TRS, balanced input jack is
suited for use with equipment having a line level output
such as high-impedance microphones, keyboard s ,
d rum machines, etc. It also accepts unbalanced TR input
cables.
16.GAIN - Adjusts the volume level of the mic/line channel.
17.TREBLE - Adjusts the high-frequency level of the mic/line
channel.
18.MID - Adjusts the middle-frequency level of the mic/line
channel.
19.BASS - Adjusts the low-frequency level of the mic/line
channel.
20.CHANNEL SEND - Adjusts the amount of signal from the
instrument channel sent to on–board DSP effects.
21.RETURN - Adjusts the amount of DSP e ffect "wet" mic/line
channel signal mixed with the "dry" overall loudness of
the Acoustasonic Pro amplifier. Rotating the knob clockwise
increases the amount of DSP effect "wet" signal. This
knob is only active when the "MIC FX ON" LED is illuminated.
22.MIC FX ON - This LED illuminates when the instrument
channel effect and the mic/line channel effect are
independent of each other (presets 79-99).

accompaniment and the TUNER switch allows
muted tuning through the instrument channel to a
suitable instrument tuner connected at the re a r
panel tuner jack. The rear panel also features two
sets of EFFECTS LOOP jacks for the connection of
e x t e rnal devices and a transformer balanced XLR
LINE OUT jack for connection to external power
amps and sound consoles. Please read thro u g h
this manual and keep it for future re f e re n c e .
23.PHASE - This push button reverses the phase of the
Acoustasonic Pro amplifier. It is useful for eliminating
certain noises when playing in small environments.
24.MASTER VOLUME - Adjusts the overall loudness of the
Acoustasonic Pro amplifier.
25.A U X I L I A RY INPUT - Unbalanced phono (RCA) input jacks
designed for use with a drum machine, tape player, CD
player, etc. and can be used for playing prerecorded
music.
26.AUX LEVEL - Adjusts the volume level of the auxiliary
input.
27.POWER INDICAT O R- This red jewel illuminates indicating
the Acoustasonic Pro is receiving power.
28.DSP EFFECTS - This data wheel selects among the various
on-board DSP digital effects. These effects will only be
h e a rd if the DSP send and re t u rn knobs on the
respective channels are turned up. See the listing of DSP
effects on the next page.
