Lavry Blue 8-channel A/D Converter 4x MAD-824 LE 4496 Analog to Digital - Blue

8 channels of great sounding sounding analog-digital conversion.

Works well and sounds great.

Includes a power cable.

Item is used and may show signs of wear from use. Please check photos for cosmetic condition. Note rack wear and a slight indentation on the face of the second MAD-824 module, shown in close up in the last photo. Also note two LED lights are out on the bottom row of the third MAD-824 module (the LEDs for "D SATURATION" and "ABC-2").

"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 operate at industry standard 44.1, 48, 88.2 and 96 kHz sampling rates, with the additional flexibility in “Wide Mode” of operation from external clocks at non-standard or variable sample rates in the ranges of 42 to 50 kHz and 84 to 100 kHz.

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. Please see “Opening the LavryBlue 4496” on page 20 for details.

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.”

Another aspect of the modular approach is that all analog audio and AES/SPDIF digital connections are made externally. The only interconnecting signals internal to the 4496 are detailed below under “Shared clocks and settings.” For example, this means that if you wanted to record the MicPre output using the M•AD-824, you would need to connect XLR cables from the MicPre output to the M•AD-824 input. Or, if you wanted to monitor the M•AD-824’s digital output through the M•DA-824, you would need to provide an AES digital connection to the M•DA-824 from the M•AD-824 or the device the M•AD-824 is feeding.

Shared AD clocks and settings: Operating multiple channels of Analog to Digital conversion with

independent clocks can creates timing or “phase-shift” differences that degrade sonic imaging. To avoid this problem, a Master Sync unit (the “M•SYNC”) controls the clocks of all AD converters in the 4496 simultaneously. It takes the form of an additional printed circuit board that is controlled by the panel on the left side of a LavryBlue equipped with AD converters. In multichannel systems, user settings such as word length or dither are typically the same across all channels, so a selectable “Master-Slave” mode is available on the M•AD-824 module. This allows the front panel parameters set on the Master module to be sent to the Slave modules so that each module does not need to be set individually."
