5. Control Full control of the stereo audio router is possible with the GYDA system controller Direct control with SNMP is being developed The module stores its routing configuration in non volatile memory when a GYDA command is given This allows complex configurations to be restored after a power loss If a GYDA system controller is present the last configuration of the module will be only be restored by GYDA if SW1 8 is off The intention is that SW1 8 is used to show that the card is manually configured when switched on 3 3 1 Audio delay lines The unit has four stereo audio delay lines connected to the audio router Audio to be delayed is routed to one of the delay inputs and the output of that delay is routed to the intended output The length of each delay line is set up on the configuration page of GYDA The maximum delay for each of the four delays is 16384 audio samples which is about 341ms The delay lines may be cascaded if longer delays are required 3 3 2 Stereo audio processing The output of each stereo signal may be manipulated LL RR LR RL LR LOR L R 2 MS this is controlled with the GYDA controller The stereo signals may be output in one of the following ways LR Left Right No change RL Right Left Channels are swapped LL Left Left Left channel is copied into the right channel RR Right Right Right channel is copied into the left channel nevion com 15 AV HD XMUX T R
