AEV ITB-302 Evolution is the new hybrid telephone model capable of meeting all the requirements for advanced management of telephone line communications. It is designed in a 19″ rack, 1 unit, and contains two internal telephone hybrids. Several ITB302 units can be interconnected to allow the expansion of “n” lines while maintaining ease of use and the possibility of remote control. The new version with DSP management is now also available.
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.
