10 ADAT Channel Mapping and S/MUX
This section describes the mapping of LSLOT channels to LT-ADAT channels. This mapping varies with sample
rate since S/MUX is required to support sample rates above the standard ADAT sample rate of 48 kHz.
At 44.1 kHz and 48 kHz there is a one-for-one correspondence between Aurora channels and LT-ADAT channels.
All 16 input and output channels are available.
At sample rates above 48 kHz, the signal channel capacity (and the number of required LSlot channels) is reduced
since S/MUX utilizes multiple ADAT channels for each signal channel. Refer to the following table.

S/MUX is enabled on demand, based on the current sample rate currently selected for recording or playback.
As such, the mapping of channels will change when the sample rate changes. The user must be keenly aware of this
“automatic” re-mapping to avoid mixing and routing problems.
When the Aurora has the SYNC SOURCE set to LSLOT, the LT-ADAT cannot determine if an incoming signal is
using S/MUX. Because of this, the user must manually set the SAMPLE RATE on the front panel of the Aurora to
match the sample rate of the ADAT device.
