Mounting the dBQzero in a rack or flight case
The dBQzero can be mounted in a standard 19inch rack or flight case via the four holes in
the front panel. Use the correct screws (not delivered) and fix the unit with all four screws.
For normal use no extra support is needed, but in more extreme conditions "on the road" we
advise to support the unit underneath the back. The dBQzero will not run very hot in normal
operating conditions, but again, under extreme hot temperature conditions we advise you to
leave 1U of ventilation space above and under the unit.
Connecting the dBQzero
Connect power to the dBQzero via the Power inlet (8), use the power cord provided with
the EQ, or get a power cord suitable for use in your country. The dBzero has an automatic
switchable power supply, which accepts a wide range of AC power: from 100V to 220V. Do
not connect the EQ to a 380V power source!!!!!
Never replace the fuse in the Fuseholder (9) with a type different than indicated on the
back panel.
All audio inputs and outputs of the dBQzero are balanced and use common cabling rules:
XLR: pin 1 = GND, pin 2 = HOT, pin 3 = Cold
JACK: TIP = HOT, RING = COLD, SLEEVE = GND
When making connections in a fixed installation you can gain time and money by directly con-
necting your cables to the screw terminal connectors.
Turn the unit on via the mains power switch (7), there will be a very short delay before the
unit will start working and the equaliser circuit is switched into circuit to avoid loud cracks and
bangs. When no power is present or the mains power switch is off, the unit will be/go in hard-
bypass mode, hereby linking the inputs to the outputs so that the signal goes true the unit
unaltered.
