ULTRAGRAPH DIGITAL DEQ1024
4. INSTALLATION
4.1 Rack mounting
The BEHRINGER ULTRAGRAPH DIGITAL requires two height
units (2 HU) for being installed into a 19" rack. Please allow at
least an extra 4" of space for the connectors on the rear panel.
Also, please make sure that sufficient ventilation of the unit is
provided for, and never put the device onto an amp or similar
equipment to avoid overheating.
Please use M6 machine screws and nuts to install your
DEQ1024 into a rack.

To disconnect your DEQ1024 from the mains, please
pull the power cord out of the socket. When your
unit is operational, always make sure you can easily
access the power socket. If you install your DEQ1024
into a rack, please make sure that you can easily
unplug the unit out of the wall socket or that you
are using an extension cord with a power switch.
4.2 Audio connections
You will need many different cables for the various
applications. The following illustrations show how these cables
should be laid out. Please use exclusively high-grade cabels.
The audio connectors of the ULTRAGRAPH DIGITAL are
electronically balanced and ensure automatic hum and noise
reduction.
Of course, you can also connect equipment featuring un-
balanced outputs. To this end, use either mono jacks or connect
ring and sleeve of the stereo jack (bridge pin 1 and pin 3 when
using XLR connectors).

4.3 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.
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 DEQ1024
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 with the popular S/PDIF interface.
A connection can be made using an adapter.
