EXPO-D

EXPO-D blocks are similar to

CobraNet Output

blocks, except they

are designed for use with AudiaEXPO-D

hardware

specifically and,

therefore, automatically allow for Internal Propagation Delay.
CobraNet® Output blocks may be used with AudiaEXPO hardware,
but Internal Propagation Delay must be manually set (0.00mS).

Mute Out

turns the output signal on/off. Level Out adjusts the relative

output volume. Invert Out reverses the polarity of the output signal.

CobraNet Bundle

assigns digital audio data to a particular bundle. CobraNet Bundle

Numbers are used to match those of the actual AudiaEXPO 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.

Telephone Interface

Telephone Interfaces provide connection and control via standard analog telephone lines, and
are available in pairs only as part of AudiaFLEX

hardware

. A Telephone Interface may consist of

as many as five separate blocks, as determined during placement into the Layout via the

Object

Toolbar

. Two primary blocks represent the audio Receive and Transmit functions. Three other

control blocks may be added individually at any time, representing functions for Dialer, DTMF
Decode, and Control/Status.
