ULTRACOUSTIC ACX1000

With the ENHANCER control you can add treble frequencies to the microphone/line signal, thus improving the audio signal’s power and transparency.

The FEEDBACK 1 control adjusts a notch filter that allows you to suppress feedback frequencies or other forms of interference. The frequency range is from 650 Hz through 4 kHz. To detect and suppress interference frequencies, please turn the FEEDBACK 1 control slowly.

The FEEDBACK 2 control determines the frequency of a second notch filter, ranging from 1.5 kHz through 9.5 kHz.

Use the EFFECT control to determine the intensity of the effect selected on the effects module (microphone/line channel).

The WARMTH control adjusts the ULTRACOUSTIC’s tube emulator circuit. The more you turn this control to the right, the more upper harmonics are added to the signals on the instrument or microphone/line channels, which results in a sound of unobtrusive brilliance with improved power and transparency.

Use this CONTROL INDICATOR to assess the amount of upper harmonics added with the WARMTH control.

To achieve the maximum tube emulation effect, both channels should be set to correct levels. The CLIP LED should be flashing with signal peaks only. Make sure it never lights up all the time.

The PHASE switch reverses the phase of the mix signal by 180°. Use this switch to eliminate feedback problems.

The MASTER control determines the overall volume level of your ULTRACOUSTIC.

The ULTRACOUSTIC features a limiter circuit in the master section. The LIM LED lights up as soon as the limiter is on.

The AUX input on the rear of your ACX1000 can be muted with the MUTE switch.

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.

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 EFFECT 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.

Select one of 99 effect programs with the PROGRAM control.

The INSTRUMENT CLIP LED lights up as soon as the effects module starts distorting. Reduce the input gain on the instrument channel.

The MIC CLIP LED lights up as soon as the effects module starts distorting. Reduce the input gain on the microphone/ line channel.

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.

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”).
