LavryBlue 4496 con 4 AD y 4 DA

Unidad con dos módulos M•AD-824 y dos módulos M●DA-824 y su reloj M•SYNC.

Especificaciones

M•SYNC SPECIFICATIONS INTERNAL CLOCK ACCURACY +/- 25 ppm (parts per million) NARROW MODE LOCK RANGE +/- 150 PPM for standard sample rates: 44.1, 48, 88.2, & 96 kHz. WIDE MODE LOCK RANGE 42-50 kHz range in “LOW” 84-100 kHz range in “HIGH” SYNC INPUT The unit accepts an input sync signal at the rear panel BNC labeled “SYNC IN.” This can be either a standard: Sample rate WORD CLOCK “5V TTL level” (2.5V-5V amplitude) or an AES SYNC SIGNAL (2.5V-5V amplitude). The input IS NOT internally terminated- please see “Regarding Termination” (below). SYNC OUTPUT The unit provides an output sync signal at the rear panel BNC labeled “SYNC OUT.” The signal is useful for driving another LavryBlue 4496 system (for example a multi-channel application requiring more than 8 channels of A-to-D). The output clock is a 75-ohm back terminated 3V signal (compatible with the BNC input of the next 4496 chassis and standard WORD CLOCK inputs). REGARDING TERMINATION If the 4496 is the only unit being fed the Word Clock signal, connect the cable using a BNC "T" adapter plugged into the “Sync In.” On the other side of the “T”, place a 75 Ohm BNC terminator connector. If the Word Clock is “chained” using “T” connectors to other devices, be sure that there is a 75 Ohm terminator on the “T” of the LAST device in the chain, and that none of the other devices have INTERNAL TERMINATION. Alternately, if there is only ONE device with internal termination, it can be wired at the “end of the chain” in place of the terminator. The important point is that there is only ONE termination and it is located at the end of the chain.

M•AD-824 SETTINGS EXTERNAL SETTINGS on M•AD-824 front panel: Wordlength selection between 24, 20 and 16 bits Reference Meter Bridge with –10, -12, -14, -16, -18 and –20dBFS reference points Peak-Hold, to hold and indicate the highest peak indicated by the meters. It is reset when quickly operating the front panel switch Dither, for proper truncation to 20 or 16 bit word length. ABC-1 and ABC-2, similar to dither, but with added noise-shaping processing.

Balanced /Unbalanced settings are configurable for Pin 2 or Pin 3 “Hot” operation via user-selectable jumpers. Individual analog output front panel volume control adjustments (20 turn potentiometers for each channel) provide 0 to +24dBu range for balanced outputs, and –6dBu to +18dBu for unbalanced operation for a digital signal of “0dBFS” (full scale digital level). Digital Input AES/EBU Balanced XLR, 110 Ohm, transformer isolated. Compatible with coaxial SPDIF using appropriate adapter.
