    Lavryblue 4496 operation 1 lavryblue 4496 system overview the lavryblue system is a modular 1u high 19 inch rack unit, configurable to accommodate multiple functions including digital to analog conversion, analog to digital conversion, and microphone pre- amplification. The hardware is designed to o...

    Lavryblue 4496 operation 2 m●sync multi-channel sync module a.) m•sync overview the m•sync supplies the clock signal for all m•ad-824’s in a 4496 frame. It is controlled by the left- most panel on the front of the 4496. If there are no m•ad-824’s in your 4496, there will not be an m•sync. In this ca...

    Lavryblue 4496 operation 5 m•ad-824 analog to digital converter a.) m•ad-824 operation the m•ad-824 is a two-channel unit, converting analog audio to aes digital output in wordlengths of 16, 20, or 24 bits. It receives its clock (internal or external) from the m•sync board (multi channel sync). All ...

    Lavryblue 4496 operation 6 1.) using the “set/select” switch on the m●ad-824 the set/select switch is intuitive and actually far easier to use than to describe! Use it to enter (or exit) the program mode by holding the switch either up or down for 3 seconds. There are individual functions (saturatio...
