The Midas XL42 is a 1U rack mounted, dual channel creative equaliser incorporating the XL4 four-band parametric equalisation with XL4 mic/line pre-amplifiers and 48V phantom supply. Each channel has input, output and pan rotary controls, 10 segment LED metering plus a switchable insert send and return point, plus DIP switches to enable automute scene control from the automute masters of XL consoles.
The purpose of this ingenious device is threefold: firstly to improve the audio quality of an inferior console by adding Midas EQ to the selected programme; secondly to create custom mixing consoles through the ability to daisy-chain multiple units. When linked together, the combined outputs will sum, producing discrete L&R channels. Finally, if a production requires, for example, 10 channels more than the input capacity of the master console, five XL42's can be fitted in a standard rack together with any required dynamic processing, which can be inserted via the XL42's insert points, thus creating a custom 10 into 2 mixer via the output daisy chain feature. The resulting L&R outputs may then be routed to the master console via any convenient point i.e. a pair of aux returns, group inputs, matrix inputs etc.
As a stand-alone unit, the XL42 is ideally suited to applications requiring a high quality front end, such as stereo recording etc.
