The Lavry Blue chassis contains a power supply equipped with additional output power noise filtering. The modules are bolted in and connected to each other in a daisy chain manner, enabling power distribution across the chassis. This interconnection also provides for communication between the units that in some cases are user selectable. One of the advantages of this approach is the ability for AD converters to “share” a common clock source- the M·SYNC- to minimize jitter and operate multiple channels in phase.

The chassis provides room for up to 4 “single width” modules. Most modules are single width 2-channel units, so the chassis has space for up to eight channels of conversion or processing. The MicPre is also 2- channel, but it takes up the space of two AD or DA modules, so one chassis can provide up to four channels of microphone preamplification. Each module has a front panel and a rear panel that are directly in-line with each other from front-to-back in the 4496 chassis.

This flexible design means that the Lavry Blue chassis can be configured to accommodate anything from a single module for stereo AD or DA conversion, to a maximum of eight channels of conversion. The unit may be configured for any mix of functions- for example: 2 channels of AD and 2 channels of DA, or 6 channels of AD plus 2 channels of DA. One popular configuration is 2-channels AD, 2-channels of DA and 2-channels of MicPre. Another advantage is that the LavryBlue can initially be purchased in a “minimal” configuration and then later upgraded to add more channels or different functions, as the user’s needs change.

All modules are added left-to-right. Because the M•SYNC provides the clock source for all A-to-D conversion, the M•AD-824 A-to-D modules must be grouped together on the left side of the 4496 chassis. M•DA-824 D-to-A converters are placed in the next available slots to the right of the A-to-D’s. The MicPre would be furthest to the right in 4496 units with converter modules. The MicPre is a doublewide module, and thus would occupy two “slots.”
