lavry ad122-96 mx
 the lavry gold ad122-96 mx allows clarity even when recordingat full scale. the audibly superior results obtained with the mxcan be a real competitive edge when recording hot.

 this beautiful piece of technology boasts extremely closeinter-channel matching that extends to the lowest signal levelspreserves the spatial placement and depth of the stereo image.ultra-stable internal and external clocking circuitry virtuallyeliminates the non-musical distortion effects caused by jitter inconversion. with unique self-calibration circuitry, conversionaccuracy is maintained over a wide range of operating temperatures,and the effects of circuitry aging are minimized.

 building on the magnificent track-record of the lavrygoldad122-96 mkiii, the ad122-96 mx retains the transparency of themkiii with the additional benefit of even more graceful handling ofclipping. the mkiii has a reputation for handling clipping withless harshness than other brands of converters, and now, the mxtakes this to a new level.

 for those who utilize clipping as a method for attainingthe maximum audible level on their recordings, the ad122-96 mxprovides a more musical result without the loss of typically associated with pushing the clipping envelope. below thehighest peak levels, the mx is as linear as the mkiii; so the best of the mkiii are retained for the majority of the musicsignal. when recording at the level where the highest peaks areclipped, the mx offers increased musicality when compared to mostother ad converters.

 for the same level of detail and accuracy, the mx modelretains the -127db noise floor 20-20khz and 0.00005% distortion forsignals below -40dbfs as the ad122-96 mkiii. extremely closeinter-channel matching that extends to the lowest signal levelspreserves the spatial placement and depth of the stereo image.ultra-stable internal and external clocking circuitry virtuallyeliminates the non-musical distortioneffects caused by jitter inconversion.

 with unique self-calibration circuitry, conversionaccuracy is maintained over a wide range of operating temperatures,and the effects of circuitry aging are minimized over years of use.in addition to the improved handling of clipped signals, lavry’sexclusive selectable soft saturation also facilitates “hotter”recording levels without undesirable artifacts.

 soft saturation is a digital emulation of analog tapesaturation which leaves the signal completely linear below thethreshold, with selectable 3 or 6db of additional level. forsignals above the threshold, the process has no attack and releasetime constants which could cause undesirable “pumping” or“breathing” by interacting with compression or limiting appliedeither before or after conversion. the mx model offers theflexibility of the soft saturation modes or linear operation, withthe ability to handle high levels of clipping without the loss in common to other converters.
