ECOS (Elenos Change Over System)  es un nuevo producto de la familia, que opera con el sistema  o series of N+1 Exchange System versiones para transmisores FM. El nuevo sistema de intercambio  N+ 1 es basado en el uso de los transmisores ETG2000 y ETG 3500.

El propósito de este sistema es de habilitar la operación de un Nuevo numero de transmisores a la ves ( máximo hasta 6) con un transmisor adicional que opera como reserve ( StandBy)

Para asegurar esta funcionabilidades, el sistema es compuesto , en el sistema mas complejo, por:

• ECHOS 6

Es es  la Unidad de Control, cual opera analizando el estado de los parámetros de operación de los diferentes transmisores, de una antena o de la señal de audio /MPX que se ha conmutado al sistema. Este dispositivo viene dentro

It is the system control unit, which operates an analysis of the different transmitters status, of antenna relay and of audio / MPX exchange matrix. This device comes into play when one of the transmitters is fault, and it manages RF, audio, MPX signal switching process to the antenna, to activate the reserve transmitter instead of the fault transmitter. ECHOS6 has all the auxiliary MPX channels necessary, that making it adequate where the system transmitters are powered exclusively by MPX signal. In all cases where just 1 transmitter requires an audio (Left and Right) or RDS signal, the device should be completed with AUDIO and MPX MATRIX.

AUDIO/ MPX MATRIX 6

This device has the task to manage audio signal switching, which occurs through an array of electromechanical relays. This device is also available as MPX MATRIX 6, whose only difference is the different type of connectors (BNC instead of XLR).

ANTENNA RELAY SYSTEM

These relay are connected to ECHOS6 with standard connectors.
