Installation; Mains Connection; Audio Connections; Midi Connection - Behringer Ultracoustic ACX1000 User Manual

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.

4. INSTALLATION

4.1 Mains connection

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°.
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.

4.2 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.

The MIDI standard (Musical Instruments Digital Interface) was
developed in the early 80’s to enable electronic musical
instruments of different makes to communicate with each other.
Over the years the range of MIDI applications has constantly
expanded, and today it is completely normal to network entire
recording studios using the MIDI standard.
At the heart of this network we find a computer loaded with a
sequencer software that controls not only the keyboards but
also effects and other peripheral devices. In such a studio you
could control your ULTRACOUSTIC in real time from a computer.
In particular, when playing live gigs you can use a MIDI
footcontroller to control both the effect parameters and channel/
effect changes on your ULTRACOUSTIC.
The MIDI connector on the rear of your ULTRACOUSTIC is an
internationally standardized 5-pin DIN jack. To connect your
ULTRACOUSTIC to other MIDI equipment, you need a dedicated
MIDI cable, which is commercially available in various lengths.
However, you can solder your own cables using 2-conductor
shielded cables (e.g. microphone cables) and two rugged 180°
DIN plugs: pin 2 (center) = shield; pins 4 and 5 (right and left of pin
2) = internal conductor; pins 1 and 3 (the outer pins) are not
used. MIDI cables should not exceed a length of 15 meters.

MIDI IN: receives MIDI controller information. The receiving
channel can be set with the buttons UP and DOWN. On = Omni,
i.e. MIDI data are received and processed on all channels (see
section 3.2).
