FDS-366T

Connections - Audio

The FDS-366T has three balanced Inputs and six balanced Outputs that can
Audio
accommodate both balanced and unbalanced signals.
Note: Because the FDS-366T outputs can be programmed for any passband,
caution must be taken when connecting the outputs to the amplifiers. The
connection of low frequency signals to high frequency drivers could cause
serious damage - this is not covered by warranty.
Please check your wiring before using the Omnidrive. During the initial set
up of the system turn the output volumes up slowly and listen for hums,
buzzes and crackling all of which could be down to faulty wiring and could
damage your speakers and/or amplifiers.

Balanced wiring

High quality twin conductor shielded audio cables should always be used for
all inputs and outputs. The two Inputs are balanced female XLRs. Input cable
shields need to be derived from the signal source end as pin 1 for the Inputs is
isolated via a low value capacitor to provide high immunity from earth loops,
whilst ensuring good EMC performance.
Signal source
Omnidrive Input
The Outputs are balanced male XLRs, with pin 1 connected to ground.
Either pin 2 or pin 3 can be used as 'hot' provided that both the Inputs and
Outputs are wired to the same standard.
