Inovonics 272 :: NOVIA FM Stereo Processor

NOVIA FM Stereo Processor


3 bands of dynamic compression with selectable crossovers

  • Built-in RDS/RBDS; compatible with all automation
  • Built-in Stereo Generator
  • Analog, AES-digital, streaming in; MPX/streaming out
  • Accepts streaming input for STL´s from IP Encoders on SHOUTcast & ICEcast
  • Full function 'responsive' Web interface works on desktop and mobile devices
  • Gated and ‘windowed’ gain-riding AGC.
  • 4 sections of parametric EQ plus an effective ‘Bass Punch’ feature
  • GPIOs, Web/email/SNMP for controls and alarms
  • Complies with North American and European standards


Frequency Response

20Hz-15kHz, ±0.25dB (with an appropriate de-emphasis network)


0.02% THD in PROOF mode


  • Analog In: >82dB
  • AES Digital In: >90dB (with an appropriate de-emphasis network)


75μs or 50μs menu-selectable

Program Line Inputs

  • Analog: active-balanced (XLR) accepts line levels between –15dBu and +15dBu; +24dBu clipping
  • AES Digital: (XLR) accepts line levels between 0dBFS and –30dBFS at sampling rates between 32kHz and 96kHz
  • IP Streaming: accepts Icecast/SHOUTcast MP3, Ogg and AAC streams

Composite/MPX Output

75Ω (BNC); adjustable between 1V p-p and 6V p-p 6% - 12% stereo pilot injection; 3% - 8% RDS/RBDS subcarrier injection

Program Signal Latency (Delay)

Approx. 3.75ms

Network Port

TCP/IP network connection (RJ45) for remote setup / operation and in/out audio streaming; full support for SNMP control

GPIO Ports

3 GPI, 3 GPO with assignable functions and logic polarity

Headphone Jack

Front-panel (TRS) 3.5mm

Internal Test Tone Generator

20Hz-20kHz; variable frequency and amplitude


Local (GPIO) closures, browser interface, SNMP and SMS/email alarms for analog, digital and stream audio loss; maintains daily, weekly, monthly logs.


  • Dayparting is simplified with an onboard real-time clock and preset-selection programming.
  • AGC: ±15dB capture range; gated with dual-rate ‘windowed’ operation
  • Leveling: variable ‘syllabic’ 2:1 compression
  • EQ: 4-sections of parametric equalization
  • Bass ‘Punch’: variable bass enhancement
  • Compression: 3-bands with selectable crossovers, variable master and individual band drive controls, plus r.m.s./peak ‘density’ adjustment
  • Final Peak Control: no-clip feed-forward wideband limiting and independent FM pre-emphasis protection limiting
  • Composite Clipping: 0dB - 3dB adjustable MPX clipping depth (exclusive of stereo pilot and RDS/ RBDS subcarrier)


Static & dynamic support for artist and song title display in PS and RT fields

Power Requirement

12VDC at 400mA (2.1mm x 5.5mm coaxial); inline switchmode power supply included

Mounting Options

An optional rack adapter mounts one or two NOVIA or other Inovonics half-rack units in a standard 19-inch, 1U rack space

Size and Weight

1.6”H x 8”W x 6”D; 5 lbs shipping weight
