30
The AUX input on the rear of your ACX1000 can be muted with the MUTE switch.
31
The AUX LEVEL control in the master section adjusts the volume level of the AUX signal (e.g. drum
computer, playback) fed in via the AUX IN or TAPE IN jacks on the rear of the ULTRACOUSTIC.
Your ACX1000 features an on-board effects module that produces 23 different types of effects comprising 99
effect variations plus associated program numbers.
32
Use the four PRESET buttons to assign an effects program to one of the PRESET buttons and recall it
from there. To save a preset selected with the PROGRAM control, simply press one of the four PRESET
buttons for about 2 seconds, until its LED lights up. To recall a stored preset, press the corresponding
PRESET button. The mix of signals adjusted with the FX RETURN control will of course be stored as
well. To adjust the MIDI receive channel, press PRESET buttons #3 and #4. Then, select a MIDI channel
with the PROGRAM control (1 through 16, “on” = Omni, “OF” = inactive). Finally, quit the menu by
pressing either one of the PRESET buttons.
33
Select one of 99 effect programs with the PROGRAM control.
34
The INSTRUMENT CLIP LED lights up as soon as the effects module starts distorting. Reduce the
input gain on the instrument channel.
35
The MIC CLIP LED lights up as soon as the effects module starts distorting. Reduce the input gain on
the microphone/line channel.
36
The DISPLAY reads the program number of the currently active preset. Use the table printed on the
effects module to locate the various groups of effects and associated program numbers. “--” means that
the effects module is disabled.
37
When you press the POWER switch on the rear of the unit, the POWER LED lights up. Be sure to
properly connect your ULTRACOUSTIC to the mains before (see chapter 3 “INSTALLATION”).

FUSE HOLDER / VOLTAGE SELECTOR. Please make sure that your local voltage matches the voltage
indicated on the unit, before you attempt to connect and operate the ULTRACOUSTIC. Blown fuses may
only be replaced by fuses of the same type and rating. Some models allow for inserting the fuse holder
in two different positions, in order to switch over from 230 V to 115 V operation, and vice versa. Please
note that for 115 V operation outside Europe, you need a fuse of a higher rating (see chapter 3
“INSTALLATION”).

Use the enclosed power cord to connect the unit to the mains.
