Visual Sound, Inc. Dual Channel Preamp & Equalizer XL42

Midas Consoles 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. Input Impedance Mic 2kOhm Balanced Mic + Pad 3kOhm Balanced Link & Insert 20kOhm Balanced Input Gain (all faders at 0dB) Mic Continuously variable from +15dB to +70dB Mic + Pad Continuously variable from -10dB to +45dB Link & Insert 0dB Maximum Input Level Mic +6dBu Mic + Pad +26dBu Link & Insert +21dBu CMR at 1kHz Mic (gain + 60dB) >70dB Mic + Pad (gain +35dB) >50dB Link & Insert >60dB Frequency Response (20 to 20kHz) Any input +0dB to -1dB Noise (20 to 20kHz) Mic EIN ref. 150 Ohm (gain + 60dB) -129dBu Transformer Mic Input EIN ref. 150 Ohm (gain + 60dB) -127dBu System Noise at 0dB (one channel only) -88dBu System Noise (20 to 20kHz) Summing Noise (12 channels routed with faders down) -83dB Line to Mix Noise (12 channels routed at 0dB, pan centre) -81dB Summing Noise (48 channels routed with faders down) -81dB Line to Mix Noise (48 channels routed at 0dB, pan centre) -75dB Distortion at 1kHz Mic (+ 60dB gain, 0dBu output) <0.03% Link (0dBu) <0.03% Output Impedance All Outputs 50Ohm Balanced Source to drive >600Ohm Maximum Output Level All Outputs 50Ohm Balanced Source to drive >600Ohm Metering Type 10 Segment LED Bargraph - Peak Reading Equaliser Hi pass slope 12dB/Oct Hi pass frequency continuously variable -3dB point from 10Hz to 400Hz Treble Gain continuously variable +15dB to -15dB Centre detent = 0dB Treble Shelving Freq continuously variable - 3dB point from 1k to 20k Hi Mid Gain continuously variable +15dB to -15dB Centre detent = 0dB Hi Mid Freq continuously variable centre from 400Hz to 8k Hi Mid Bandwidth continuously variable 0.1 Oct. to 2 Oct.
