5. CONNECTIONS
5.1 MIDI connections
Your DEQ2496 incorporates a MIDI interface, which allows
you to send and receive MIDI data. It is thus possible to integrate
the unit into a recording studio and control it from a computer-
based sequencer program.
The MIDI connectors on the rear of the unit are internationally
standardized 5-pos. DIN jacks. You need commercially available
MIDI cables to connect the ULTRACURVE PRO to other MIDI
equipment.
MIDI IN: receives MIDI control data. Adjust the receive channel
in the UTILITY menu.
MIDI THRU: the MIDI THRU jack allows for passing on incoming
MIDI signals without modification, for example, to daisy-chain
several ULTRACURVE PROs.
MIDI OUT: sends MIDI data to a connected computer or another
ULTRACURVE PRO. Transmitted formats are program data and
status information for signal processing.
5.2 Analog connections
As a standard feature, the BEHRINGER ULTRACURVE PRO
DEQ2496 has electronically balanced inputs and outputs. The
circuit design features automatic hum and noise reduction for
balanced signals and allows for trouble-free operation, even at
highest operating levels. Externally induced mains hum, etc. is
thus effectively suppressed. The servo function, which is also
automatic, recognizes the connection of unbalanced pin
assignments and changes the nominal level internally so that
there is no difference in level between the input and output
signals (6 dB correction).
+ Please ensure that only qualified persons install
and operate the device. During installation and
operation the user must have sufficient contact to
earth. Electrostatic discharges might affect the
operation of the unit.

5.3 Digital connections
(AES/EBU and S/PDIF)
The AES/EBU interface whose name is derived from the Audio
Engineering Society and the European Broadcasting Union, is
mainly used in professional studio environments and broadcasting
studios for the transmission of digital signals, also over greater
distances. The connection is made via balanced XLR cables
with a wave resistance of 110 ohms. Cables can be up to 100 m
long. With some minor adaptations, even cable lengths of over
1 km are possible (not rare in radio and TV applications).
The interface complies with the AES3 format, which allows
for the two-channel transmission of signals with a resolution of
up to 24 bits. The signal has an auto-clock and auto-
synchronization feature (important when several digital devices
are used). An additional wordclock connection between DEQ2496
and connected AES/EBU equipment is therefore not required.
The sample rate is not fixed and can be chosen freely. Typical
rates are 44.1 kHz, 48 kHz, 88.2 kHz and 96 kHz. The AES/EBU
interface is largely compatible to the popular S/PDIF interface. A
connection can be made using an adapter. On the
ULTRACURVE PRO the format can be switched to S/PDIF.
