Macrotel D2 is a digital double-line telephone hybrid, featuring superior performances for Radio and TV phone connections requirements.

With the variety of telephone systems in the world today, from cellular mobile phones to analog and to digital, it's increasingly difficult to have all callers sound the same on-air in a broadcast environment. Macrotel D2 use digital signal processing (DSP) technology to continually adapt to telephone-line conditions and to deliver the maximum audio isolation.

The two Macrotel D2 telephone lines are internally conferenced, and the output can be combined as a single two separate channels on your console. Macrotel D2 also features a complete set of the most advanced remote control and connection facilities such as automated answering and ducking system.

Macrotel D2 is therefore ideal when the very best audio quality and uniformity is required for talk shows, news feeds, production, recording studios.
