Operating environment

This appliance is designed to operate in moderate climates at 

a temperature between 5 and 40°C (41 - 104°F) with relative 

humidity no more than 60 %.

Should the unit be installed in an equipment rack, it is important 

to ensure that the operating temperature inside the rack does 

not exceed the upper limit. This could be the case where the 

rack contains power amplifiers. A cooling fan may be necessary 
in such installations.

Power requirements

BEFORE  you  connect  any  unit  to  the  mains,  please  make 

sure that your local AC supply is within the range of voltages 

required by the unit.

The dBQ-zero is designed to work from an AC supply between 

100 V and 240 V, at a frequency between 50 and 60Hz. No AC 

voltage selector is provided as the device automatically adjusts 

to the incoming AC voltage.

Precautions should be taken so that the appliance is properly 

grounded at all times. 

This unit must be earthed.

Installation

If the unit is brought into a warm room from a cold environment, 

internal condensation may occur. Wait an hour or two before 

switching it on so that it can reach the ambient temperature.

Although  this  unit  is  intended  for  installation  in  a  standard 

19-inch rack it can nevertheless be used freestanding. If the 

unit is installed in a flight-case or in an equipment rack, fix the 

unit with all four screws through the front panel holes. 

For  normal  use  no  extra  support  is  needed,  but  in  more 

extreme conditions, such as on the road, we recommend the 

unit is supported at the rear.

Allow at least 10 cm (4 inches) at the back, front and sides of 

the unit for sufficient ventilation.
