The analog audio level of the Ross NK-A64-HQ routers offers unparalleled configuration and audio processing, allowing users to mix left and right audio channels to suit their broadcast requirements. Channels may be swapped, phase inverted or converted to mono (both channels left, both channels right, both channels average, sum and difference).
The NK-A64 Analog Audio Level Router has a control layer in addition to the first and second levels (left and right channels respectively). The control layer is used for lossless signal mixing.
Signal processing is conducted by way of a Control Layer. The Control Layer is an additional level within the router matrix that may be mapped to control panel keys to allow users to mix audio channels on the fly. The Control Layer uses SOURCE keys as the triggers to mix the output audio signal. The Control Layer may be used after a source has been switched to a selected destination. Table 12.1 shows the audio mixing options available for the Control Layer.
The Analog Audio Control Layer can easily be accessed from NK Series control panels. Factory configured systems will allow the NK-A64 Control Layer to operate out of the box. Further configuration of the NK-A64 Control Layer and control panel options requires the NK-IPS.
* When assigning breakaways for NK Series control panels, the Control Layer should not be assigned to a breakaway that contains other levels. If users require a breakaway for the NK-A64 Control Layer, it is vital that it is the only level active for that breakaway.
