Audio Connections
The FDS-334T/336T has two balanced Inputs and either six (336T) or four (334T) balanced
Outputs that can accommodate both balanced and unbalanced signals.
Note: Because the FDS-334T/336T 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 Minidrive. 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 Minidrive 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.

Note: All diagrams show pin 2 as the ‘Hot’ connection and pin 3 as the ‘cold’, in some
applications this standard may need to be reversed.
