ONAIR, 7 to 1 Audio Switch

AS-18 model Audio Switch has been designed to connect desired audio input to output manually using front panel LCD/keys or by means of a command from its RS232 control input. It is used in the N+1 transmitter projects to connect the audio and RDS inputs of the broken transmitter to the redundant transmitter. AS-18 is also able to put desired audio channel to a built-in speaker and display the audio level on the vu-meter.

AS-18 has 8 inputs and 8 outputs audio channels. 7 of the inputs are external and the last one is from internal remote control board (integrated audio player & URL) which can be managed remotely via internet or WiFi. 7 of the outputs are directly connected to the external devices like transmitters and the one for switched channel like redundant transmitter. When a transmitter has a problem in N+1 system, it sends a command to AS-18 and redundant transmitter by means of RS485 and coaxial switch. AS-18 changes the audio inputs&RDS of the redundant transmitter with the broken transmitter and coaxial switch changes its position to connect the broken transmitter to the dummy load and redundant transmitter changes its frequency and RF power limit to the broken transmitter values. It can be chose the integrated audio player as an audio input of broken transmitter or the others manually via front panel LCD/keys or remote control (WiFi/ethernet).

Any of the analog audio inputs can be listened via 6.3mm audio jack on the front panel selecting via LCD/keys or Remote Control website. While listening one of the audio input, the indicator LEDs shows the input audio level of the selected input. 

Modular design of the AS-18 allows you to expand the number of the audio inputs between 2 and 8. Every audio part contains 3 XLR (analog audio+MPX) and 2 BNC (MPX and RDS). Input boards are hot-pluggable so it is very easy to decrease or increase the input number of the device.
