5.CONNECTIONS

5.1MIDI 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.

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.
