Control Panels for X75 Systems Installation and Operation Manual xvii
Preface
Working Environments E4 and Class A
This product is intended for professional use in a controlled EMC
environment such as a purposely-built broadcast studio.
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
75Ω 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.
