LavryBlue 4496

Product Description

The LavryBlue 4496 is a modular system that can house stereo AD, DA, and MicPre modules. There are four "slots" available in each 4496 chassis, and multiple chassis can be used together for additional channels in multi-track applications. Each converter module occupies one slot and each MicPre module occupies two slots. The 4496 can be ordered with as few as one module or up to eight channels of conversion. The MSYNC module provides clock and external synchronization to all AD modules in a chassis, as well as a BNC Word Clock output.

Features

Clocking (MSYNC)

• Multichannel clock synchronization
• Ultra-stable crystal-referenced internal or external sync operation at 44.1, 48, 88.2, and 96 kHz
• Wide lock mode is available for non-standard sample rates or vari-speed operation
• One M·SYNC provides clocking and synchronization for all M·AD824 AD converter modules contained in the same 4496 chassis
• Word Clock out to synch other units

Analog to Digital (MAD-824)

• 2 channels of sonically transparent 24 bit Lavry A-to-D conversion
• Option to output digital audio 24 bit, 16 bit, or 16 bit plus dither and αcoustic βit Correction™ noise shaping.
• Accurate LED metering.
• Analog and Digital Saturation modes allow hotter recording levels.

Digital to Analog (MDA-824)

• 2 channels of sonically transparent Lavry D-to-A conversion
• CrystalLock™ mode option eliminates the effects of source jitter on conversion accuracy.

Preamplification (MicPre)

• 2 channels of professional micpre
• Impedance matching for Condenser, Dynamic, and Ribbon mic’s
• Super-low noise and distortion over a wide input and gain range
• Transformerless electronically balanced inputs and outputs provide sonic transparency with excellent channel matching.

Applications

• Tracking
• Location Recording
• Overdubs
• Broadcast
• Live/Location Sound
• Post Production

Connections

1.) Line outputs The MDA-824 and MicPre have XLR line outputs for balanced or unbalanced connection. XLR to RCA adapters or adapter cables can be used for connection to equipment with RCA inputs.

The XLR outputs can be configured for balanced or unbalanced connection using the internal jumper settings for "pin 2" and "pin 3;" which refer to the pin numbers of the XLR output connectors. The standard wiring for XLR to RCA adapters or adapter cables is to connect Pin 3 to Pin 1 ("ground") and pin 2 carries the signal. Thus, the correct internal jumper setting for both the XLR to RCA adapters and standard adapter cables is "Pin 2 Hot unbalanced. Please see the LavryBlue manual for setting instructions, and the Operation section of the manual for more details.

The XLR output is Pin 2 "+" and Pin 3 "-" for normal signal polarity. Thus, for the MDA-824 with balanced or unbalanced Pin 2 "+" connections, the signal polarity is "normal" or "non-inverted" when the front panel POLARITY switch is set to "Pin 2" Changing the Polarity setting to "Pin 3" will result in inverted signal polarity for balanced and unbalanced Pin 2 "+" connections.

The MicPre does not have a polarity setting. The XLR output is Pin 2 "+" and Pin 3 "-" for normal signal polarity as long as the input is connected with Pin 2 "+" wiring.

2.) Line inputs The MAD-824 has balanced XLR inputs. The balanced configuration is recommended for both balanced and unbalanced line level sources.

The XLR input is Pin 2 "+" and Pin 3 "-" for normal signal polarity when the internal DIP switch position #2 setting is "Off" (the factory default setting). Thus, for the MAD-824 with balanced or unbalanced Pin 2 "+" connections, the signal polarity is "normal" or "non-inverted." Changing the internal DIP switch position #2 setting to "On" will result in inverted signal polarity for balanced and unbalanced Pin 2 "+" connections.

The XLR input of the MicPre is designed to accept only low-impedance balanced professional microphone inputs or ribbon microphone inputs. The input offers excellent common-mode rejection and the polarity matches the XLR output (Pin 2 "+").

3.) Digital input The MDA-824's digital input is a female XLR connector; which can accept AES inputs or SPDIF inputs using a simple wired XLR to RCA adapter or adapter cable. Use of an impedance matching transformer is not recommended as long as guidelines for coaxial SPDIF connection cable length are followed.

The status of the digital input is displayed by the MDA-824 on the front panel by a Lock indicator and sample frequency indicators. If the input is "locked" to a valid signal; the front panel Lock indicator will illuminate. If it is not locked due to no connection or an invalid signal; the Lock indicator will not illuminate. If you have any problem when setting up the MDA-824, please check the Lock indicator to see if the MDA-824 is locked to a valid input signal.

4.) Digital output The MAD-824's digital output is a male XLR connector; which transmits AES stereo digital audio. Teh output can be used to feed most SPDIF inputs by using a simple wired XLR to RCA adapter or adapter cable. Use of an impedance matching transformer is not recommended as long as guidelines for coaxial SPDIF connection cable length are followed.

5.) Synchronization The MSYNC multichannel synchronization module proves BNC connections for Sync input and Word Clock output. The Sync input can accept either Word Clock or AES sync, and the type of sync i selectable using the front panel Internal/Word Clock/AES switch. The front panel also has a "Lock" indicator that illuminates when the MSYNC is synchronized to the external input (but never during internal clock operation). There are setting for the sample frequency; which must be set properly for internal or external operation, and a "Wide-Narrow" PLL mode switch for external operation. Narrow provides the lowest jitter external synch. operation, and Wide mode is provided for non-standard frequencies between 40 an 50 kHz (such as vari-speed applications); but will not provide as much immunity from jitter as the Narrow mode.

There is also a "2X" switch on the MSYCN rear panel to be used ONLY when feeding the MSYNC a sync signal at one-half the output sample frequency of the MAD-824 in external operation. If you cannot get the MSYNC to show "Lock" to an external 88.2 or 96kHz sync signal; double-check the setting of the 2X switch to be certain it is "Off."
