Connecting the Dymand
MAINS CONNECTION
Before connecting the Dymand to the mains power, ensure that the local supply corresponds with the
operating voltage, and check whether the fuse is properly rated. Both operating voltage and fuse are
noted on the label on the back of the device.
Mains voltage fluctuations of ±10% are allowed, so normal mains voltage tolerance should not cause
problems.
Mains voltage connection is by means of a standard 3-pin IEC socket. The central pin of this
connector is wired to the chassis of the Dymand and
must , for safety reasons, be connected to earth
at all times.
AUDIO CONNECTION
All audio connections, inputs and outputs, are electronically balanced on gold plated XLR-3
connectors. The connections are:
1 - Ground
2 - Signal, in phase (+)
3 - Signal, out of phase (-)
For maximum performance we recommend balanced connection with two-conductor twisted pair
shielded signal-cable, ordinarily this shield is only connected at one end of the cable.
INPUTS: The inputs of the Dymand are electronically balanced with high common-mode rejection.
These inputs are compatible with most professional and semiprofessional audio equipment,
balanced or unbalanced.
When the Dymand is driven from an unbalanced source, the shield should be connected to the
circuit-ground of the source.
Terminal 2(+) should be connected to the driving-source signal output.
Terminal 3(-) should be connected to ground (terminal 1).
When the Dymand is driven from a balanced source, the shield should be grounded at the
source-end only.
OUTPUTS: The outputs of the Dymand are electronically balanced and simulate true transformer
operation. Because the outputs are electronically floating, terminal 2(+) or 3(-) may be grounded
without fear of short-circuiting the driveramps.
Always ground the shield of your cable at the Dymand side only, by connecting it to terminal 1 of
the XLR socket.
When driving an unbalanced load, connect terminal 2(+) to the signal input and terminal 3(-) to
the circuit ground of the driven equipment.
