DL32R Owner's Manual Chapter 2 : DL32R Front Panel Introduction Each DL32R mixer is outfitted with 24 XLR input jacks, 8 combo input jacks, 14 XLR output jacks, an XLR AES output jack, 1/4" L/R monitor output jacks, one 1/4" phones output jack (and corresponding phones knob) and power and network LEDs. Let's take a look at each of these features, starting with the inputs. XLR and 1/4" Inputs All channels may accept a balanced mic or line-level signal using an XLR connector. They are wired as follows, according to standards specified by the AES (Audio Engineering Society).

To connect balanced lines to these inputs, use a 1/4" Tip-Ring-Sleeve (TRS) plug. "TRS" stands for Tip-Ring-Sleeve, the three connection points available on a stereo 1/4" or balanced phone jack or plug. TRS jacks and plugs are used for balanced signals and stereo headphones and are wired as follows: RING SLEEVE SLEEVE RING TIP TIP RING TIP SLEEVE 1/4" TRS Balanced Mono Wiring: Sleeve = Shield Tip = Hot (+) Ring = Cold (-) To connect unbalanced lines to these inputs, use a 1/4" mono (TS) phone plug, wired as follows: SLEEVE TIP SLEEVE TIP TIP 1/4" TS Unbalanced Mono Wiring: Sleeve = Shield Tip = Hot (+) SLEEVE 5
