· Sample rate indicators: these indicators show the sample rate of the main Atlas signal path.
Standard rates of 44.1kHz, 48kHz, 88.2kHz, 96kHz, 176.4kHz and 192kHz are supported. For
more information, see the
· Host indicator: this indicator is normally lit green, to show that Atlas is connected to the host
computer via the USB interface; however, when lit red, it indicates that the unit is using the MDIO
(multi-channel digital IO) expansion module to connect to a non-USB host, as described in the
MDIO expansion slot
Ethernet, in which state the Host indicator will be lit orange.
· Master indicator: this is lit when the device is set to local (internal) sample clock, and off when
locked to an external sync source; it flashes when local sync has over-ridden an invalid external
sync source selection. For more information see the
