Midas XL42 2-Channel Microphone Preamplifier
Midas XL42 2-Channel Microphone Preamplifier
The Midas XL42 is a 1U rack mounting, dual channel creative equaliser incorporating the XL4 four-band parametric equalisation and XL4 mic/line pre-amplifiers with +48V phantom power. Each channel has input gain, output level and pan rotary controls, 10-segment LED metering plus a switchable insert send and return point. The XL42 also features Automute scene control from the Automute masters of XL consoles, which are enabled by DIP switches on the rear of the unit.
