This same behavior applies to 3 4 in when selected aes in The fifth option aes in connects the ports 1 2 out and 3 4 out directly to physical AES EBU input of the VX442 The left channel of the aes in input is transmitted to 1 2 out and the right AES EBU In channel is connected to 3 4 out 6 The sixth option aes inv in functions similarly to the third option except that the left and right channels are swapped Therefore in this mode the left channel of AES EBU In is routed to 3 4 out and the right channel of AES EBU In is routed to 1 2 out Note that this option is exclusively for monitoring mixing purposes the AES EBU In will not record in reverse when this option is checked At this point you may begin to realize versatility and potential of the Mixer You may want to re read this section and practice making some adjustments within the VX442 Control Panel software to become proficient in routing and mixing You can reset the default values to use the card as an ordinary 6 inputs outputs device simply select the option reset located on the upper right of the control panel The Hardware tab The Hardware Settings tab of the VX442 Control Panel gives you control over miscellaneous features of the VX442 To display this page click the Hardware tab of the VX442 Control Panel sample settings B internal ASIO WDM buffer size external aes ebu
