4.1 Desktop Director

The Telos Desktop Director is both a control surface for putting calls on-air and a telephone

set for conversations with callers on the studio telephone lines. The Director has two modes of

operation – Producer (screener) mode and Talent (on-air) mode.

Tip

Since certain functions work differently in Talent versus Producer mode, it is important to
understand that there are two modes, and how to switch between them.

Status Symbol Icons

The Desktop Director uses Status Symbol icons displayed on the LED matrixes located between

the two columns of line select buttons. Here is what each icon means:

Line is ready for incoming or outgoing calls

Line is in-use by another studio

(in two-studio modes only)

Line is ringing

Call is on hold

Call is On-Air – Column 1
