DISTRIBUTION AMPLIFIER/ZONE MIXER/MIC SPLITTER DA-410.
BALANCED OUTPUT:
GROUND LINK
In some installations, it might be necessary to isolate the distribution amplifier/zone
mixer/mic splitter electric ground, from the system mains earth, in order to avoid ground loops that
could generate unwanted noises. For this reason, the unit provides an EARTH-LINK switch placed
at the rear panel in order to lift the mains earth from the unit.
MAINS EARTH LINKED WITH THE DISTRIBUION AMPLIFIER/
ZONE MIXER/MIC SPLITTER ELECTRIC GROUND.
MAINS EARTH LIFTED FROM THE DISTRIBUION AMPLIFIER/
ZONE MIXER/MIC SPLITTER ELECTRIC GROUND.
NOTE:
For security reasons, the earth connection to the mains is linked with the unit chassis in both
cases.
CAUTION:
Always operate the unit with the AC ground wire connected to the
electrical system ground. Precautions should be taken so that the means of
grounding of a piece of equipment is not defeated. For this circumstance,
NEVER
lift
the mains earth AC ground to avoid possible accidents. For your security, NEVER use
ground isolator adapters; instead it is recommended the EARTH -LINK switch.
