AEQ said it has incorporated talkback in its line of NetBox routers.
NetBox 32AD MX is an audio matrix with 64 analog, digital and IP inputs and outputs. NetBox DSP has between 64 and 160 inputs and outputs, all of them IP.
“These units respond to the concept of ‘mixed routing,’ in which audio over IP is used, over the AES67 or Dante protocol to simplify wiring and facilitate transport to a router that has, among other things, IP inputs and outputs, and is equipped with features for high-level audio routing and processing,” AEQ wrote.
Those features include logical line grouping, salvos, macros, agenda, silence detection, time scheduling, level meters, signal generator, audio mixing and processing, IP transport of GPIOs and multiplex group management.
These are managed through a multi-post and multi-user application, based on customized views to control one or more local or remote audio matrices for various uses in radio, television and sound systems.
“For its use in radio, giving way to several correspondents, and in television, operating remote intercom, the Talkback or MPX function has been developed,” AEQ said.
“A ‘Talkback’ group is a combination of input and output lines that allows to automatically execute an N-1 routing between these lines,” it said.
“But to facilitate the work, an additional keypad has been created to the XY screen of the matrix. The coordinator listens to correspondents at will using the PFL buttons. He integrates each correspondent to the program, and at the same time joins him to the talkback group, by means of the Mute OFF buttons (Active in yellow).”
The coordinator speaks to each or all correspondents, using the Talk buttons, during which time the reception of the N-1 from the other correspondents is eliminated or attenuated by 20 dB each.
When a Talkback is created, the inputs, outputs and crossover points involved are cleared or cleared. The gains of all Talkback related crossover points are set to 0 dB.
