New Digital Telephone Hybrid 2 channels
Description telephone hybrid AEV ITB 302 Evolution
AEV ITB-302 Evolution is the new telephone hybrid model can meet all the latest requirements for the advanced management of communications via telephone lines. It is designed in a 19 “rack, 1 unit; and it contains two internal 2 telephone hybrids. different units of ITB302 can be interconnected to allow for expansion to “n” lines while maintaining the ease of use and the possibility of remote control.
Telephone lines, properly filtered and isolated, allow the audio conference between them and the DJ. An internal microprocessor provides an array of features that, until now, have been difficult to provide in the same unit. All potentiometers have been eliminated to solve problems of wear. All adjustments are made digitally.
The adaptive adjustment to the telephone line is automatically performed by the hybrid without the need for operator intervention
Remote commando units
ITB 302 Evolution comes with a remote command dedicated, through which effect the coupling line and the introduction of the Meeting of the incoming calls of the two channels.
multi-line connection
several ITB 302 Evolution units can be connected in cascade, you can then expand the system and manage all telephone communications through a single input channel and one of the mixer’s output without having to make any change, but simply by connecting between them the various ITB 302 through the appropriate connectors.
In addition to the 2-wire phone, on the apparatus is also the connections TX & RX 4-wire.
