Additional EMC Information
This device is for professional use in a controlled EMC environment, such as
purpose-built broadcast studios.
EMC regulations require that the radiation emitted from this unit does not
exceed certain limits. These limits are only met when the front panel is closed
and the two thumb screws are secured.
Compliance to the EMC regulations is also dependent on the use of suitably
shielded (screened) cables. Coax cables should be of the double-shielded
(screened) variety. Unused BNCs should be fitted with 75
Ω
terminations.
All audio cables should be screened with the shield (screen) making good
contact with the metallic parts of the cable connectors.
D-type connectors used with this unit should always have metallic shells with
the shield (screen) of the cable mechanically bonded to the metal shell. It is
further recommended that the D-type cable connectors be of the “dimple”
variety. These connectors make a better contact and consequently improve EMC
performance.
