Connecting your DS8000: Connecting your DS8000: Connecting your DS8000: Connecting your DS8000:
Inputs
The inputs are made via 3-pin XLR connectors, which are electronically balanced as standard,
and should be connected via a high grade twin core screened cable, as follows:
PIN1: Screen (see note)
PIN2: Hot (signal +)
PIN3: Cold (signal -)
The unit is designed to operate with fully balanced equipment and ground loops or loss of
performance may be experienced if connected to unbalanced sources. If it is unavoidable
however, the following wiring should be used. The cable should still be twin core plus screen.
PIN1:
Screen - connected to the chassis of the unbalanced equipment - or left disconnected
at the unbalanced end.
PIN2: Hot (signal +)
PIN3: Cold (ground 0V)
NOTE: This unit is wired to the latest industry recommendations. PIN1 is connected directly
to the chassis/mains earth on the FOH and MON outputs only. If ground loops (mains hum)
are encountered try using the ground lift switches on the rear panel. If problems persist,
consult your dealer/supplier.
DO NOT TAMPER WITH OR ALTER ANY GROUND (EARTH) CONNECTIONS INSIDE THE UNIT.
Outputs
Outputs are also made via 3-pin XLR connectors wired as follows:
PIN1: Screen (see note)
PIN2: Hot (signal +)
PIN3: Cold (signal -)
Note that the rear panel outputs are electronically balanced and so are not galvanically
(electrically) isolated. Front panel outputs are transformer balanced and so are isolated.
External Supply
This socket must only be used to connect directly to another DS8000 and NOT as an input
from a separate supply. Attempting to connect another supply to this socket will damage the
unit and invalidate the warranty.
Connection to another DS8000 is via a standard 5-pin to 5-pin XLR cable wired 1-1. Please
keep this cable as short as possible (ideally 1-2 metres maximum) to prevent voltage drop
affecting both units’ performance in the event of a back-up situation.
