Chapter 3: Getting Started

Connecting to unbalanced equipment

Ideally, you will be making the best use of the DN540’s low-noise high-headroom balanced inputs by connecting to similarly balanced equipment. However, if you do have to connect to unbalanced devices, the following wiring is recommended for best results (see Figure 3):

•Connect the +ve (pin 2) of the balanced connection to the +ve terminal on the unbalanced connector.

•Connect the -ve (pin 3) of the balanced connection to the common (ground) terminal on the unbalanced connector.

•Connect the ground (pin 1) of the balanced connection to the common (ground) terminal on the unbalanced connector.

The following diagram shows the wiring details for the insert send/return 1/4” TRS connector/XLRs.

Your unit is now ready to operate.

To switch off the DN540, switch off the mains at the mains power outlet. Then, to electrically isolate the unit, remove the mains cable from the mains IEC socket on the rear panel.
