The Advanced dialog for
newer AEC-2HD cards
includes added features.
Ref
, Mic, and Out
display levels at the AEC
Ref block and at the AEC
block (pre & post AEC
respectively). Echo
Detect
indicates AEC in
progress. Echo Path
Changed
indicates AEC
converging. Min
Threshold
prevents
AEC re-convergence due
to momentarily low levels
(such as muted mics).
EXPI
EXPI blocks are similar to CobraNet Input blocks, except they
are designed for use with AudiaEXPI hardware specifically and,
therefore, automatically allow for Internal Propagation Delay.
CobraNet Input blocks may be used with AudiaEXPI hardware,
but Internal Propagation Delay must be manually set (1.00mS).
Adjust AudiaEXPI input trim (gain) controls so that Peak In
flashes only occasionally (6dB headroom). Mute In turns the
input signal on/off. Level In adjusts the relative input volume.
Invert In
reverses the polarity of the input signal.
CobraNet Bundle assigns digital audio data to a particular bundle number.
CobraNet® Bundle Numbers are used to match those of the actual AudiaEXPI
hardware being used in the system. Normally, 'unicast' bundles 256 ~ 65,279 are
selectable. These are device specific bundles (for exchange of digital audio with
only one other device). Multicast allows selection of bundles 1 ~ 255, which are
not device specific (for exchange of digital audio with multiple devices). Enable
turns on/off the exchange of CobraNet digital audio data from this device.
Right-clicking over certain settings will provide a menu of
additional options.
