Introduction
The IFB Plus Series Model 2 Central
Controller from Studio Technologies is a
highly integrated, two-channel IFB (inter-
rupted foldback or interrupted feedback)
system contained in a single rack space
unit. It is expressly designed to provide
talent cueing for ENG, SNG, and mobile
production facilities. The performance
and features of the Model 2 reflect the
needs of contemporary applications. Only
after extensive polling of field production
and engineering personnel was the Model
2’s feature group established. We think
you’ll find the Model 2 a great addition
to your facility.
