ULTRAMIZER PRO DSP1424P
4. INSTALLATION
Your BEHRINGER ULTRAMIZER PRO was carefully packed in the factory and the packaging was designed to
protect the unit from rough handling. Nevertheless, we recommend that you carefully examine the packaging
and its contents for any signs of physical damage, which may have occurred in transit.
+
If the unit is damaged, please do not return it to us, but notify your dealer and the shipping
company immediately, otherwise claims for damage or replacement may not be granted.
Shipping claims must be made by the consignee.
4.1 Rack mounting
The BEHRINGER ULTRAMIZER PRO fits into one standard 19" rack unit of space (1 3/4"). Please allow at
least an additional 4" depth for the connectors on the back panel. Be sure that there is enough air space
around the unit for cooling and please do not place the ULTRAMIZER PRO on high temperature devices such
as power amplifiers etc. to avoid overheating.
4.2 Mains connection
The mains connection of the ULTRAMIZER PRO is made by using a mains cable and a standard IEC recep-
tacle. It meets all of the international safety certification requirements.
+
Please make sure that all units have a proper ground connection. For your own safety, it is
advisable not to remove the ground connection within the units or at the supply, or fail to
make this connection at all.
Before you switch on the unit, check that it is configured to match your AC mains voltage requirements. If it
does not comply, then it is necessary to switch the operating voltage to the correct supply requirements
BEFORE turning on the unit, otherwise the unit could be severely damaged. You will find this combined fuse
holder/voltage selector at the back, adjacent to the IEC receptacle. IMPORTANT: This does not apply for
general export models which are built for one operating voltage only.
The AC voltage selection is defined by the position of the fuse holder. If you intend to change the operating
voltage, remove the fuse holder and twist it by 180 degrees before you reinsert it. Matching the two markers
monitors the selected voltage.
+
If the unit is switched to an other operating voltage, the fuse rating must be changed. See the
technical specifications for further information.
A safety fuse protects the unit from serious defects. If the fuse blows, this is a warning sign and always
indicates that the circuit is overloaded. The fault must always be repaired before the fuse is replaced. If the
safety fuse is faulty and needs replacing after the unit is repaired, please make sure that you replace it only
with the identical type and rating. NEVER use fuses of different ratings or cover faulty fuses with aluminum foil.
This can cause fire and electric shocks and will endanger your life and the lives of others.
4.3 Audio connections
As standard, the BEHRINGER ULTRAMIZER PRO is installed with electronically servo-balanced inputs and
outputs. The new circuit design features automatic hum and noise reduction for balanced signals and thus
allows for trouble-free operation, even at high operating levels. Externally induced mains hum etc. will be
effectively suppressed. The automatic servo-function recognizes the presence of unbalanced connectors and
adjusts the nominal level internally to avoid level differences between the input and output signals (correction
6 dB).
+
Please ensure that only qualified persons install and operate the ULTRAMIZER PRO. During
installation and operation the user must have sufficient electrical contact to earth. Electro-
static charges might affect the operation of the ULTRAMIZER PRO!
