There is also a fully-featured monitoring section with bass management (3 sets of speakers + subwoofer), Foldback A and B with individual talkbacks for headphone mixes and a built in Listen Mic input + classic compressor circuit, with its own direct output. At mixdown the mono channel DAW return signals can be routed to the CUE ST bus and then summed into Mix A, so there are 16 main faders + 16 Cue ST inputs + 4 Stereo channels providing 40 summing inputs (using the stereo returns and insert Sum functions you can squeeze in over 50 summing inputs). Each channel has a Cue Stereo Bus section (with Pan and Volume) used to provide one of the headphone mixes while tracking. Direct outputs on every channel, stereo return and mix bus enable convenient stem printing. There are two mono aux sends and two stereo return inputs. The Busses and channels can access the 500 rack and each have a separate insert point for processing. There are four main Mix Busses (A, B, C, D) with buses B, C and D able to be summed into Mix A. The rack has its own dedicated high spec' power supply. XL-Desk ships with a legendary SSL Stereo Bus Compressor module in slots 17 & 18 (hard wired to Mix A). There is an 18 slot 500 format rack built in that can be used for processing or mic pre's. The first eight channels have VHD mic pre's. It has 20 channel strips: 16 dual input mono (switchable between main input or DAW return) and 4 stereo channels. XL-Desk is in many ways a traditional 24 into 8 analogue console but it packs in an incredible collection of features. XL-Desk is designed for tracking or mixing engineers who require an analogue console within a DAW centric studio, but don't want or need the integrated DAW control and analogue level automation other SSL console products have made the new hybrid studio standard.
