Use the SELECT button to toggle the
ANALOG OUT bank of LEDs between the
analog metering display (above) and
the clock status display (below). If the
2408mk3 has no clock, it won’t switch
out of the clock display (into metering).
Figure 5-1: In PCI mode, the 2408mk3 settings can only be changed from the computer, and the SELECT button toggles the
ANALOG OUT bank of LEDs between analog output metering and a status display of the 2408mk3’s current settings.

The two sample rate LEDs flash when the PCI-424
system cannot detect a digital audio clock. For
example, if you’ve chosen ADAT sync as the Clock
Source in the PCI Audio Console window, but there
is no ADAT connected (or it is turned off), the 44.1
and 48 kHz LEDs will flash.
These three LEDs indicate that the 2408mk3 is in PCI
mode and displaying its current clock settings (as
chosen in the PCI Audio Console software).
In PCI mode, these two rows display the current
clock settings in the 2408mk3 (as set in the PCI
Audio Console software on the computer).

“PCI” means that the 2408mk3 is
slaved to the PCI-424 card’s audio clock.
In this example, the clock source is the
SPDIF digital input of the 2408mk3
(which is active on Bank C).
