List of accessories available for all variants of this family
Este micrófono consta deun Micrófono tipo 4954soldado con láser a un preamplificador de micrófono de ¼". La unidad se ensambla en un entorno de sala limpia y se sella, después de lo cual se le asigna un único número de tipo y un único número de serie. Esto significa que la unidad combinada tiene mejor precisión y estabilidad a largo plazo y se maneja como una unidad completa.
Los transductores se pueden conectar a cualquier entrada CCLD y son compatibles con IEEE P1451.4 V0.9 TEDS (hoja de datos electrónica del transductor). La unidad también contiene TEDS, lo que significa que en ella se almacena información sobre el número de serie, el tipo y la sensibilidad.
