UL TRACOUSTIC ACX1000

1. INTRODUCTION

Thank you very much for expressing your confidence in BEHRINGER products by purchasing the ULTRACOUSTIC
ACX1000. With the ULTRACOUSTIC, you have acquired a state-of-the-art 2-channel amplifier that can be
operated easily and quickly, and enables you to create out-of-the-ordinary sounds for a variety of applications.

6

UL TRACOUSTIC ACX1000

1.1 The design concept

The philosophy behind BEHRINGER products guarantees a no-compromise circuit design and employs the
best choice of components. The operational amplifiers used in the ULTRACOUSTIC are exceptional: they
boast extreme linearity and very low distortion characteristics. To complement this design, the choice of
components include low-tolerance resistors and capacitors, high-quality potentiometers and several other
stringently selected elements.

The ULTRACOUSTIC uses SMD technology (Surface Mounted Device). These subminiature components adapted
from aerospace technology allow for an extreme packing density to further improve the overall reliability.

The super-robust steel enclosure of your ULTRACOUSTIC, with its generously proportioned high-capacity
power supply and temperature-controlled active fan, makes sure that your ACX1000 keeps on working even
when the going gets tough. The cabinet is made of high-grade, non-polluting E1-MDF boards, which are
grooved, multi-glued and free of formaldehyde.

1.1.1 Tube emulator

A special FET circuit in your ULTRACOUSTIC emulates the positive characteristics of a tube exciter, producing
additional harmonics and a subtle compression effect which gives your guitar sounds the power to make
themselves heard and adds sustain and definition. Acoustic guitars, in particular, with their wide dynamic
range, need to produce a homogeneous sound image in all registers. The FET circuit makes sure that even the
high registers have sufficient sustain and won’t get drowned. While the WARMTH control allows you to add the
tube sound effect as desired.

By using solid-state components we succeeded in eliminating tube-specific interference noise to a great
extent; the actual tube effect is thus achieved without additional noise or hum.

1.2 Before you begin

Your BEHRINGER ULTRACOUSTIC was carefully packed in the factory and the packaging is designed to
protect the unit from rough handling. Nevertheless, we recommend that you carefully examine the packaging
and its contents for any signs of physical damage, which may have occurred during transit.

+ If the unit is damaged, please do not return it to BEHRINGER, but notify your dealer and the

shipping company immediately, otherwise claims for damage or replacement may not be
granted. Shipping claims must be made by the consignee.

Be sure that there is enough space around the unit for cooling and please do not place the ULTRACOUSTIC on
high temperature devices such as radiators etc. to avoid overheating.

+ Before you connect your ULTRACOUSTIC to the mains, please make sure that your local voltage

matches the voltage required by the unit!

The mains connection of the ULTRACOUSTIC is made by using the enclosed mains cable and a standard IEC
receptacle. It meets all of the international safety certification requirements.

+ Please make sure that all units have a proper ground connection. For your own safety, never

remove or disable the ground conductor of the unit or of the AC power cable.

The MIDI connection (IN) is made with standardized DIN plug-in connectors. An optocoupler has been used for
isolated data communications.

You will find additional information in chapter 3 “INSTALLATION”.

1.3 Control elements

UL TRACOUSTIC ACX1000

8

UL TRACOUSTIC ACX1000

+ Please note that with all three EQ controls set fully to the left (instrument channel), the resulting

signal will be very low-volume.

10

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 65 Hz through 400 Hz. To detect and suppress
interference frequencies, please turn the FEEDBACK 1 control slowly.

11

The FEEDBACK 2 control determines the frequency of a second notch filter, ranging from 150 Hz
through 900 Hz.

12

Use the FX RETURN control to determine the intensity of the effect selected on the effects module
(instrument channel).

13

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

14

The balanced LINE/INST. jack of the microphone/line channel can be used for line-level signals, e.g.
keyboards, samplers etc.

15

The +48 V switch activates the phantom power supply for the XLR microphone input, providing the
operating voltage required for condenser microphones.

16

Use the GAIN control to determine the volume level of the microphone/line channel.

17

When the input signal overdrives the microphone/line channel, the CLIP LED signals this condition.
Reduce the input gain with the GAIN control, until the CLIP LED just stops lighting up. Occasional
flashing of the CLIP LED, caused by signal peaks, is harmless though, because the microphone/line
channel, too, has sufficient headroom.

18

The BASS control in the EQ section allows you to boost/cut the bass frequencies on the microphone/
line channel.

19

With the MID control you can boost/cut the midrange frequencies on the microphone/line channel.

20

Finally, the TREBLE control governs the microphone/line channel’s high frequency gain.

21

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

22

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.

23

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

24

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

25

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.

26

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.

27

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

28

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

29

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

1. INTRODUCTION

UL TRACOUSTIC ACX1000

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”).

1.3.2 Rear panel

38

Use the POWER switch to put the ULTRACOUSTIC into operation.

39

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”).

40

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

SERIAL NUMBER. Please take the time to have the warranty card filled out completely by your specialized
dealer, and return it within 14 days after the date of purchase, so as to be entitled to benefit from our
extended warranty. You may also use our online registration option available on the Internet at
www.behringer.com.

42

Connect the enclosed footswitch to the FOOTSWITCH jack. The footswitch allows you to recall the four
effects presets.

43

MIDI IN. This connector gives you MIDI remote control over your ULTRACOUSTIC. You can change
effects programs by means of program change commands.

44

The TUNER output always provides the instrument channel’s audio signal to feed an external tuner.

45

The balanced DIRECT OUT jack provides a line-level copy of the instrument channel’s signal. Use this
jack to connect an external power amp or mixing console.

46

Your ULTRACOUSTIC also features a serial stereo master insert path, which allows you to insert
external effects devices. These are the MASTER INSERT SEND jacks for the left and right channels,
which should be connected to the inputs of the external effects device. You can also tap a stereo signal
from these connectors.

47

These are the MASTER INSERT RETURN jacks for connection to the outputs of an external effects
device.

+ Please note that when using the serial effects path, the external effects device should not be

set to 100% wet (100% effect signal); otherwise, there will be no direct signal portion fed back
to the ULTRACOUSTIC.

48

The TAPE OUT provides a stereo copy of the ULTRACOUSTIC’s audio signal, e.g. for recording purposes.
The TAPE OUT is on RCA jacks.

49

The TAPE IN jacks perform the same function as the AUX IN. However, due to the RCA connectors you
can also connect a tape deck or hi-fi system directly to the TAPE IN jacks.

50

The AUX IN allows you to feed in additional stereo signals, for example, to play with a drum computer
or some sort of playback. Additionally, you can use the AUX IN in combination with the INSERT SEND
as a parallel effect path: connect the INSERT SEND to the input and the AUX IN to the output of the
effects device (INSERT RETURN jacks should not be used in this case!). Thus, the signal path inside
the amplifier will not be interrupted and you can add the effect portion from the external device, using the
AUX LEVEL control. Please note that the external effects device must be set to 100% wet for this
purpose.

This is the MIC INS. SEND jack of the microphone/line channel’s insert path. Connect this jack to the
input of an external effects device or compressor.

This is the MIC INS. RETURN jack of the microphone/line channel’s insert path. Connect this jack to
the output of an external effects device.

The instrument channel also features an insert path. This is the INSTR. INS. SEND jack.
The INSTR. INS. RETURN jack is used to feed back the effect signal to the ACX1000.

T ab. 2.1: The effect algorithms of the ULTRACOUSTIC

A very special feature of your ULTRACOUSTIC is its built-in multi-effects processor that creates a variety of
first-class, studio-compatible algorithms. This effects module provides a total of 99 preset, organized in 23
different groups of effects. Each group comprises a number of presets with varying parameter settings and
covering a broad spectrum of effects and effects combinations.

The range of effects provided consists of single, parallel and dual effects. The single and parallel effects provide
an effect or effects combination for both channels. The dual effects allow you to give each channel its own
effect.

Use the four PRESET buttons to store one effects program each, including the mix ratio adjusted with the
FX RETURN controls (original vs. effect signal for both channels). To store a preset selected with the PROGRAM
control, simply press one of the four PRESET buttons for about 2 seconds, until its associated LED lights up.

To recall the four presets stored, press one of the PRESET buttons or one of the four buttons on the enclosed
footswitch.

2.1 MIDI control

With its built-in MIDI interface you can control the ULTRACOUSTIC via MIDI, for example, to select effects from
a MIDI sequencer (studio), or from a master keyboard or MIDI footcontroller (live).

12

2. EFFECTS T ABLE

UL TRACOUSTIC ACX1000

Connect the MIDI IN jack of your ULTRACOUSTIC to the MIDI OUT jack of a MIDI footcontroller. Now, enable
the MIDI functions on your ULTRACOUSTIC by pressing the PRESET buttons #3 and #4 for about two seconds:
the two control LED’s of PRESET buttons #3 and #4 start flashing, the right decimal point in the display lights
up. Select a MIDI channel with the PROGRAM control (1 through 16, “on” = Omni, “OF” = inactive) and quit the
menu by pressing either one of the PRESET buttons. “Omni” mode means that your ULTRACOUSTIC receives
and processes MIDI information on all MIDI channels. Of course, you should select the same channel both on
your MIDI footcontroller and ACX1000 (see MIDI footcontroller user’s manual).

You can select presets via MIDI using program change commands. When you send program change command
#127, the effects module of your ACX1000 will be bypassed, i.e. you will hear no effect. As is usual with MIDI
program change commands, program change #0 corresponds to program #1, and program change #1 to
program #2, etc. (see table 4.1 in the appendix). The program change numbers 99 through 102 select the
preset stored for the four PRESET buttons. After changeover the preset is activated immediately, i.e. it will not
be affected by previously adjusted bypass settings.

3. INSTALLATION

3.1 Mains connection

Please ensure that the ULTRACOUSTIC is set to the correct supply voltage before connecting the unit
to the AC power system! Three triangular markings can be found on the fuse holder at the AC power connection

socket. Two of these three triangles will be aligned with one another. The ULTRACOUSTIC is set to the
operating voltage shown next to these markings and can be switched over by twisting the fuse holder by 180°.

IMPORTANT: This does not apply to export models designed only for 115 V ~!

The mains connection of the ULTRACOUSTIC is made by using the enclosed mains cable and a standard IEC
receptacle. It meets all of the international safety certification requirements.

3.2 Audio connections

Except for the MIC and LINE/INST. inputs and the DIRECT OUT, the audio inputs and outputs of your
BEHRINGER ULTRACOUSTIC are on unbalanced connectors. Please use commercially available RCA
connectors for the TAPE inputs and outputs.

+ Please ensure that only qualified persons install and operate the ULTRACOUSTIC. During

installation and operation the user must have sufficient electrical contact to earth. Electrostatic
charges might affect the operation of the ULTRACOUSTIC!
