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.
