DS800 Page 8
Grounding
The DS800 has a direct connection between Pin 1 of the Input XLR’s, Front of
House XLR’s, Monitor XLR’s and the IEC mains inlet earth terminal.
Under No
circumstances should the mains ground be removed from the DS800.
The transformer isolated Output XLR’s have their Pin 1’s not connected.
To avoid ground loops and noise it is recommended that the following precautions
be observed.
1. All equipment connected to the DS800 should be balanced. Any equipment that
is not balanced should be interfaced via a suitable balancing system e.g. D.I.
box or balancing transformer.
2. Use high quality screened cable and multi-core cable throughout the system.
3. Run all the power for back-line, monitor position, front of house, control and the
DS800 from a star point (single phase).
Cooling
If you mount several DS800’s in a rack
Please
fan cool the rack with a minimum of
one fan @ 35CFM per 6 DS800’s, blowing air into the rack (positive pressure). This
will extend the life and the reliability of the units. The DS800 has been specifically
designed to reside in an enclosed positive pressure rack, so that cool air forced into
the back of rack migrates though the units and exits via the front panel slots.
