iv Redbox User Handbook
Your Redbox, please contact your supplier, because an IEC connector is always
supplied from the Sonifex factory. If for any reason, you need to use the Redbox with
a different power cable, you should use the following wiring guidelines:
Wire Colour Connection
Green, or green and yellow Earth (E)
Blue, or Black Neutral (N)
Brown, or Red Live (L)
Ordering the Correct Mains Lead
When ordering a Redbox from Sonifex, it is helpful if you can specify your required
operating voltage and mains lead. After the product code add:
UK, for 230V, UK 3 pin to IEC lead
EC, for 230V, European Schuko 2 pin to IEC lead
US, for 115V, 3 pin to IEC lead
AU for 230V, Australasian 3 pin to IEC lead
Fig W-1: Mains Lead Table
E.g. order RB-BL2 UK for a UK IEC lead to be supplied.
Installation Information
Atmosphere
The units should be installed in an area that is not subject to excessive temperature
variation (<0°C, >50°C), moisture, dust or vibration.
Electromagnetic Radiation
The cover is connected to earth by means of the fixing screws. It is essential to
maintain this earth ground connection to ensure a safe operating environment and
provide electromagnetic shielding.
Please note that due to the large gain range of the RB-MA1/MA2 microphone
amplifiers, there can be a degradation of the audio signal if used near to sources of
intense electromagnetic radiation (e.g. video monitors and power cables).
