Ref: SOLYDINE-MX2400 Categoría: Tags , , , , , ,

“El Codec-Mixer 2400 es una consola portátil con calidad de audio digital, robusta y confiable. Creada para muchos años de uso duro. Con gabinete de duraluminio aeronáutico, liviano muy resistente.

Posee entrada/salida digital USB para conectarse a Netbooks y Tablets. Asimismo incorpora una nueva CPU interna que permite usar los modems 3G/4G de telefonía celular, para transmitir en forma inalámbrica por Internet.

Todos los potenciómetros son de cerámica conductiva de un millón de operaciones (100 veces más que los de su actual consola…).

El uso de amplificadores de muy bajo consumo, tal como los empleados en naves espaciales de la NASA, permiten 16 horas de trabajo con sus baterias recargables de NI-Metal. Aún alimentando el modem 3G y la CPU interna pueden obtenerse más de 6 horas de autonomía

Tiene entradas para 5 MIC balanceados con Phantom de 48V, una línea estéreo y 3 líneas mono balanceadas.

Posee salidas para 6 auriculares con amplificador distribuidor interno, salida estéreo y mono balanceada, asi como salida Ethernet para conexión directa a Internet por streaming de audio TCP/IP en mono o estéreo.

Usando un módem USB 3G/4G estandard, provisto sin costo por las empresas de telefonía, se puede conectar a la red celular de Internet, transmitiendo así desde cualquier lugar del mundo sin necesidad de costosos links. También puede operar usando la conexión WiFi existente en muchos lugares.

La MX2400 codifica en MP3 el streaming de audio y por lo tanto no requiere un decoder en Estudio pues recibe señal con cualquier PC de la radio como si fuera una radio de internet.

La MX 2400 permite transmisiones analógicas simultáneas pues tiene un Hibrido Telefónico incorporado o por Celular conectado en forma inalámbrica por Bluetooth.
