LSLOT In 1 16 will be assigned to Digital Out 1 16 Please note that with an LT USB installed LSLOT sources correspond to USB audio streams coming from the host computer By default these audio streams are delivered Page 27 of 45 900908 to the Analog Outputs By manually assigning LSLOT sources to the Digital Outputs these signals can be mirrored to the Aurora AES EBU outputs as well For example to send USB audio streams to the digital outputs assign LSLOT 1 16 for an Aurora 8 assign LSLOT 1 8 to the digital outputs as SOURCE A and set TO DIGITAL OUT to REMOTE These faders allow control over the output level of each monitor source when in Remote Routing mode This level attenuation occurs in the digital domain so it is recommended to leave these faders in their default maximum position in situations where the highest fidelity is required Holding down the SHIFT key on the keyboard while adjusting a fader will allow adjustment of channel pairs This display reveals the amount of attenuation in dB of a monitor source This button enables the mute function for the associated monitor source This display indicates the status of the digital inputs If a valid digital signal 1s present the display will indicate Locked If a valid digital signal 1s not present the display will indicate Unlock This drop down menu allows for selection of the clock source that drives the Aurora sample clock generator fr

7. samples Smaller buffer sizes will give you lower latency However if a buffer size 1s too small for the system or context audio anomalies such as clicks and pops may occur It is recommended to become familiar with altering the LT USB buffer size to best suit the context of use Once you determine the lowest achievable buffer size you will typically have to double the size each time you double the sample rate but the effective latency will remain constant For example if a system 1s capable of operating at a buffer size of 128 samples at 48 kHz then for a 96 kHz project the buffer size will likely need to be increased to 256 samples 3 4 3 Monitoring Theory The Aurora supports hardware based low latency monitoring on a global or per channel basis Monitoring settings can be established using the Aurora Remote Control software These methods avoid delays caused by monitoring through software applications 8 4 3 1 Global Routing Global routing can be established from the Aurora Remote Control software on the Digital I O amp Settings Page The choices for routing to the analog and digital outputs are ANALOG IN AES IN LSLOT IN and REMOTE Setting TO ANALOG OUT to LSLOT IN is the appropriate setting when the intention is to send play streams from the computer to the Aurora and to record audio from the Aurora inputs into the computer Setting TO DIGITAL OUT to LSLOT IN does not route USB audio streams to the

Aurora 16 in 8 channel mode would be to lower the overall system CPU usage The fewer channels a device presents to the host computer the lower the CPU consumption regardless of how many channels are actually being used for playback or recording Lower CPU usage can be beneficial in terms of latency performance or number of audio plug ins processes that can be used in a project For example if playing back a stereo file while operating in 16 channel mode at 48 kHz the CPU consumption is equivalent to the playback recording of all 16 channels at 48 kHz For this situation it would be recommended to operate in 8 channel mode thereby significantly lowering the CPU usage 8 1 1 Operating at 176 4 192kHz This feature 1s only available in 8 channel mode Running the device at these rates in 16 channel mode will result in distorted audio and other unpredictable behavior 8 2 Use with USB 1 0 USB 2 0 and USB 3 0 systems Because USB is a standard written to be backwards compatible with previous versions all USB 3 0 ports will be able to accept a USB 2 0 device USB 1 0 1s currently not supported 8 3 Choosing a USB Port USB performance and reliability depends heavily on other traffic that shares the USB bus In the ideal situation the LT USB would be the only device connected to one of the computer s host controllers Each host controller provided by a computer acts as an independent USB bus and allows connections for multiple devices through
