Also see model: 262 NOVIA Stereo Processor & Leveler

The NOVIA 272 FM Stereo Processor is a half-rack, digital audio processor with Stereo-Gen and RDS for FM radio broadcast.

NOVIA´s parametric equalizer offers continuous control over the audio signal's frequency content with 3 bands of dynamic compression and selectable crossovers.

With particular stress on ease of installation and use, the NOVIA 272 incorporates intuitive, multi-language menu-driven setup, as well as an IP/browser interface compatible with any PC or mobile device. Multiple factory and user-defined processing presets streamline the setup process. IP connectivity also provides local and email failure alarms, plus support for SNMP operation.

The NOVIA 272 accepts both program line and streaming inputs and allows remote IP audio monitoring.

Audio Processing for an Authentic Sound


  • 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

75μs or 50μs menu-selectable

Program Line Inputs

  • Analog: active-balanced (XLR) accepts line levels between –15dBu and +15dBu; +24dBu clipping, impedance 600 ohms
  • AES Digital: (XLR) accepts line levels between 0dBFS and –30dBFS at sampling rates between 32kHz and 96kHz

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
