2. CONTROL ELEMENTS AND CONNECTIONS

ULTRACOUSTIC ACX450/ACX900/ACX1800

The MIC jack is the balanced XLR microphone input of the microphone/line channel.

The balanced LINE jack (1/4") of the microphone/line channel can be used forline-levelsignals, e.g. from keyboards, drum computers, etc.

The COMPRESSOR controller is used to adjust the intensity of the compression (only in ACX1800, see chapter 4.3).

The compressor is switched on/off with the IN/OUT switch (only in ACX1800).

With the FX SELECT controller, you can select one of 16 effect programs. For a detailed description of the available effects, see table 4.1 in chapter 4.2.

With the PARAMETER controller (only in ACX1800) you can edit certain effect parameters. For details on the parameters that are adjustable for each effect, see table 4.1.

The IN/OUT switch (not included in ACX450) allows you to activate the selected effect. If an effect has been activated, the LED in the switch is on. Alternatively, you can switch the selected effect on and off with the foot switch.

The FX LEVEL controller is used to adjust the level (share) of the selected effect.

With the MASTER controller, you can adjust the overall volume of the ACX1800.

The PHASE switch reverses the phase of the mix signal by 180° (only in ACX1800). Use this switch to eliminate problems with feedback.

3.1Connecting options for the ACX450

Fig. 3.1: Cabling options of the ACX450

The above cabling is suitable for sessions in the rehearsal room or for practicing at home. Connect your guitar to the instrument input jack of channel 1. If desired, connect another instrument or a dynamic microphone to channel 2.

Connect the supplied FS112 foot switch to the foot switch input at the rear panel. With the foot switch, you can switch the effects units of both channels on and off, which is particularly useful during live performances.

To play along with a playback, connect a CD player to the CD input. Of course, a MD player or a computer can be used as playback device as well.

3.2 Extended connecting options (ACX900 and ACX1800)

Fig. 3.2: Extended connecting options (ACX900 and ACX1800)

Models ACX900 and ACX1800 offer a wide range of additional connecting options. The above figure shows only one of many possible installations:

The instruments, microphones, the foot switch as well as the CD player are connected as shown in figure 3.1. The tuner is connected to the tuner output where there is a constant instrument signal. If you wish to integrate external effects units, you can do this separately for each of the two channels. Connect the input of the effects unit to the INSERT SEND of one of the respective channels, and connect the effect output at the unit to the INSERT RETURN jack of the same channel. Instead of the two stage effects units shown here connected in series in the signal path, you can establish a parallel effects loop, e.g. by means of a 19" studio effects unit. In this case, connect the input of the effects unit to the MIC INSERT SEND or the INSTRUMENT INSERT SEND output, and feed the stereo output signal of the effects unit through the CD INPUT jacks. You can then use the CD LEVEL controller to mix the effects signal and your guitar signal. With this option, please note that the effects unit only returns the effects signal (100%Wet) and not the original signal.

Musicians who wish to play their instrument through a PA system during a live session normally need a DI box. A DI box prepares the signal for transfer through long cable lines, so that a higher output level for the mixing desk can be achieved. You will be delighted to know that your ULTRACOUSTIC comes with a builtin DI box! Connect the balanced LINE outputs directly to the mixing desk input or to the multi-corefeeding to the mixing desk. Use a microphone cable(two-coreshielded cable with XLR connectors).

4. SOUND PROCESSING

The ULTRACOUSTIC offers many options for sound processing. The ACX1800 includes, for example, an FBQ equalizer, a multieffects unit and a compressor. The various processing options are explained in this chapter.

4.1 FBQ equalizer

A graphic equalizer with FBQ spectrum analyzer is available for sound adjustment and correction. If the sliding controllers are in neutral position (0), the signal is not modified.

sTo boost the frequency range, move the respective sliding controller up.

sTo dampen the range, move the sliding controller down.

sPress the FBQ switch to activate the FBQ display.

FBQ function: Each controller is equipped with a LED indicating the level of the associated frequency range of the controller by means of its brightness. This assists you in identifying the controller that must be used to edit the sound. If the sound is for example too dull or too droning, one of the LEDs is probably very bright, indicating the sliding controller that should be moved down to reduce the bass level. On the other hand, you can quickly identify frequency ranges whose level is too low (LED barely lit) to increase it.

+To emphasize certain frequency ranges, it might not be necessary to raise these, but to lower the levels of the other frequencies by moving the respective sliding controllers down. This approach prevents excessively high internal signal levels, thus retaining valuable dynamic reserves (“headroom”).

4.2 Digital effects processor

One of the key features of your ULTRACOUSTIC are the two built-inmulti-effectsprocessors that operate independently of each other in both channels. Each effects module offers a total of 16 different programs that are grouped in four categories.

sTo switch effects on or off, press the IN/OUT switch at the ULTRACOUSTIC or at the foot switch.

sTurn the FX SELECT controller to select a program. The effects are described in the following overview:

Table 4.1: Effects programs

sUse the FX LEVEL controllerto make the effect audible.

sEdit the effect using the PARAMETER controller (only in ACX1800).

The reverb presets are effects that imitate the reverberation of various large rooms. Use the PARAMETER controller to adjust the reverberation time (decay).

1CHAMBER simulates the typical characteristics of a studio. This effect is useful in cases where you need unobtrusive reverb to liven up the signal.

2ROOM: Reverberation typical for rooms of medium size, with clearly audible reverb from walls.

3HALL: Simulation of a lively large hall with considerable echo.

4CONCERT simulates the prolonged reverb in a large concert hall.

This group includes four modulation effects that are generated in different ways. For each effect, you can adjust the depth and speed of the modulation.

5CHORUS give guitar signals more depth and width. This is achieved by means of a modulated delay of the input signal.

6FLANGER: Popular guitar effect achieved by constant modulation of the tone pitch.

7PHASER: The phase effect is similar to the flange, but somewhat subtler. It is achieved by superimposing a phase-shiftedeffects signal on the input signal.

8TREMOLO: Intensive variation of the volume at a preset rate.

This group includes a number of dual effects where for example a chorus or flanger effect is combined with a delay. In the ACX1800, you can adjust the volume of the delay effect.

9 CHORUS/DELAY with a delay of 400 ms.

10FLANGER/DELAY with a long delay (400 ms)

11CHORUS/DELAY with a short delay (300 ms).

12FLANGER/DELAY with a delay of 300 ms.

In this group you find delay effects with different delay times. The “Feedback” parameter determines the number of repeats.

13Short DELAY of 80 milliseconds (ms).

14Medium DELAY of 300 ms.

15DELAY of 400 ms.

16Long DELAY of 500 ms.

4. SOUND PROCESSING

ULTRACOUSTIC ACX450/ACX900/ACX1800

4.3 Compressor (only in ACX1800)

The compressor reduces the dynamic range of a signal. Volume peaks are lowered, and low signals are boosted, so that the difference between the loudest and the lowest tone of an instrument or voice is reduced. This results in a more expressive and homogeneous sound, and the sustain of long tones is prolonged.

sSwitch on the compressor (ON switch ).

sTurn the COMPRESSOR controller slowly in clockwise direction to increase the compression intensity.

sCompare the compressed and the original signal by switching the compression ON and OFF (at the ON switch).

If the input signal to the compressor is high, it operates at its optimum range. If the signal is low, the effect becomes only audible when the compressor controller is set to a very high position. If a compressor is switched on in this position, there is a risk of sudden level changes. If GAIN is set to a high value, the same compressor effect is achievable without having to set the controller to a high value. In this case, the COMPRESSOR controller does not have to be turned to a position near the stop in order to achieve any effect. We recommend that you try this out until you have found the best settings!

5. INSTALLATION

5.1 Audio connections

With the exception of the balanced LINE jack mono input, all inputs and outputs of the BEHRINGER ULTRACOUSTIC are unbalanced mono jack sockets. The LINE OUT connections are designed as balanced XLR outputs. The CD inputs are designed as RCA connectors.

+Please ensure that only qualified persons install and operate the ULTRACOUSTIC. During installation and operation, persons handling and using the equipment must be sufficiently earthed, as electrostatic discharge might affect the operation of the ULTRACOUSTIC!
