DSC260 Preliminary Owners Manual Revision 0.9
2.0 Getting Started
2.1 Unpacking: Carefully unpack the controller and inspect it for possible concealed shipping damage. Save the packing in case any
damage is discovered and contact the dealer from whom you purchased the controller. In the event the DSC260 is ever shipped
outside of a rack, keep the packing for reuse.
2.2 Mechanical Mounting: The DSC260 occupies one standard rack space (1U). When mounted in an equipment rack that is
transported, it should be supported by a shelf or other equipment to prevent flexing of the mounting ears.
2.3 AC Power Connections: A 3-wire grounded outlet must always be used. The DSC260 will accept input AC from 100 - 240 Volts, 50-60
Hz. The DSC260 does not have a power switch and must be shut down by removing the IEC power connector.
The ground terminal of the IEC plug is required by wiring codes and regulations. It must always be connected to the
electrical installation safety ground. The DSC260 has carefully designed internal grounding and balanced inputs and
outputs to reduce the chance of ground loops (hum). If hum occurs see Appendix A for suggested correct audio signal
wiring and system grounding. Replace fuse only with a new fuse of correct size (20 mm) and rating (T1A250v).

2.4 Audio Connections: The DSC260 has two balanced inputs and six balanced outputs that can accommodate both balanced and
unbalanced signals and are wired with Pin 2 hot. The two female XLR inputs are balanced, with pin 1 isolated to prevent ground
loops. The six male XLR outputs are balanced, with pin 1 connected to ground. Pin 2 or pin 3 can be used as "hot" provided that
the inputs and outputs are wired to the same standard. Two conductor shielded audio cable should always be used for all inputs
and outputs.
Note: Because the DSC260 outputs can be programmed for any passband, caution must be taken
when connecting the outputs to the amplifiers. Miswiring can connect low frequency information to
high frequency drivers causing serious damage (not covered by warranty) to the drivers.
2.5 Controller Connections: MIDI in, out and thru jacks are located on the back panel. These allow remote program recall and MIDI sysex
dump capability. In addition, an RS-232 connector allows updating of the Flash Memory as software updates become available.
More information on these procedures is contained in Appendix C.
