DN540
Operator Manual 17
Chapter 5: Rear Panel
The rear panel of the DN540 (shown below) has a mains input section and four channel
connector sections.
Note: Although the rear panel of the DN540 has cutouts for two solo bus connectors,
these are unused on this unit and are therefore blanked off.
Mains input
The mains input section has a mains
IEC socket, below which is a fuse
drawer. Printed just to the right are
the mains supply voltage and fuse
details.
The mains input is an auto voltage
sensing, switch mode power supply
that operates where normal mains
voltage is in the range 100V AC to
240V AC.
The fuse drawer houses the mains fuse
at the rear of a two-compartment drawer. The front compartment provides room for a
spare. Always replace the mains fuse with one of the same type of and rating, as
printed to the right of the fuse drawer.
Channel connector section
There are four similar channel sections on the
rear of the DN540. Each section comprises a
male (output) and a female (input) XLR chassis
connector, and a 1/4” TRS connector. These are
for connecting to external line level signals, such
as a mixing console’s insert connections.
