INTRODUCTION
Product Description
Inovonics’ NOVIA 272 is a comprehensive FM airchain pro-
cessor that includes the stereo-multiplex generator and a
full-function RDS/RBDS encoder compatible with station au-
tomation ‘playout’ systems.
The NOVIA 272 features gain-riding AGC, leveling, paramet-
ric EQ, 3-band dynamic range compression, wideband and
independent pre-emphasis-protection final limiting, and ad-
justable composite clipping. Programmable from the front
panel or through its cross-platform Web interface, the
NOVIA 272 also supports 2-way program streaming and
SNMP.
Product Features
Features of the Inovonics NOVIA 272 include:
Comprehensive audio processing with factory and
user presets; internal scheduler allows dayparting
Accepts analog, AES-digital and streaming program
inputs; out-streams source and processed audio for
remote monitoring
Failover feature can switch to an alternate program
feed when primary audio is lost
Easy setup using the OLED screen and jog-wheel nav-
igation of the processor’s menu tree
Full-function Web interface works with any browser
Self-logging alarms for audio loss; alarm ‘tally’ for
remote indication; alarm also dispatches email or
text message alerts
Accurate front-panel LED metering; all processing
functions metered with OLED display and Web inter-
face
