System Description
As ON AIR Audio inputs/outputs two independent analogue or digital Au-
dio interfaces (digital: one AES/EBU interface) are available. If the AES/EBU
interface is selected, both channels are multiplexed together (right/left chan-
nel). The inputs have separate digital Sample Rate Converters (SRC). For syn-
chronisation with an external clock a clock input and a clock output are avail-
able.
Two separate PRETALK interfaces are available in all three operating modes.
Two Telephone Handsets or Headsets (Options: ID: # YT6032/ # YT6033) can
be connected for PRETALK. In the POTS operating mode you can connect two
standard POTS Telephones for dialling and Pretalk.
The advantage of a handset/headset over a POTS Telephone is the possibility
to switch between ON AIR and PRETALK anytime. With a telephone con-
nected to the hybrid, it is only possible after the caller has been switched to
ON AIR and if the telephone has not been hung up.
b-line XT can be operated primarily via the front keypad and the illuminated
display.
The configuration and operation is especially comfortable via the Talkmaster
XT
®
Software (see CHAPTER 5) included in delivery, which communicates
with the system via the LAN interface. You can install up to three PC work-
places (additional Talkmaster XT
®
Software Licences required, ID:
# YT6038).
Most basic operating functions like accepting a call, dropping a connection
and establishing a connection with a pre-programmed number can be carried
out via four programmable TTL contacts. Two relays are available for status
indication.
Additionally, the operation can be carried out via up to two b-line XT Key-
pads (see CHAPTER 6) which can be connected to the RS232 interface.
