Physical Characteristics

RedNet A8R/A16R dimensions are illustrated in the diagram above.

RedNet A8R/A16R requires 1U of vertical rack space and at least 350 mm of rack depth, to allow for 
cables. RedNet A8R/A16R weighs 4.52 [4.78] kg and for installations in a fixed environment (eg., a 
studio), the front-panel mounting screws will provide adequate support. If the units are to be used 
in a mobile situation (eg., flight-cased for touring, etc.), it is recommended that side support rails or 
shelves  should be used within the rack.

Cooling is by fan assistance from side to side. The fan used is low-speed and low-noise to allow for 
an ambient operating temperature of 50 degrees Celcius. 
[RedNet A16R has two fans, at higher ambient operating temperatures the fans will increase in 
speed to allow for an ambient operating temperature of 50 degrees Celcius.]

Ventilation is via slots in the enclosure at both sides. Do not mount RedNet A8R/A16R immediately 
above any other equipment which generates significant heat, for example, a power amplifier. Also, 
ensure that when mounted in a rack, the side vents are not obstructed.

Power Requirements

RedNet A8R/A16R is mains-powered. It incorporates ‘Universal’ power supplies which can operate 
on any AC mains voltage from 100 V to 240 V. The AC connections are made via a standard 3-pin IEC 
connectors on the rear panel.

When PSU A & PSU B are both connected, PSU A becomes the default supply and therefore draws 
more  current  than  B.  If  a  backup  mains  supply  is  provided  from  an  uninterruptable  source,  it  is 
recommended that this is connected to input B.

Mating IEC cables are supplied with the unit; these should be terminated with mains plugs of the 
correct type for your country.

The AC power consumption of the RedNet A8R/A16R is 24 [41] W.

Please note that there are no fuses in RedNet A8R/A16R, or other user-replaceable components of 
any type. Please refer all servicing issues to the Customer Support Team (see “Customer Support 
and Unit Servicing” on page 18).
