NOVIA 236 is expressly tailored for medium-wave monaural AM broadcasting. It combines the functions of slow, ‘gain-riding’ AGC, ‘syllabic’ consistency leveling, 4 stages of parametric EQ, 3 bands of dynamic range compression with variable crossovers, ‘brick wall’ bandwidth restriction and a final no-splatter peak controller that supports asymmetrical carrier modulation.

Setup and operation are simplified with 10 factory and 10 user-defined processing presets.

Setup and operation are simplified with 10 factory and 10 user-defined processing presets. In addition, the IP interface allows 2-way program streaming, plus total remote control of the NOVIA 236 using any PC or mobile device. SNMP operation is supported.

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

The NOVIA 236 accepts both program line and streaming inputs and allows remote IP audio monitoring.




  • Gated and ‘windowed’ gain-riding AGC

  • Unique, adjustable ‘syllabic leveling’

  • 3 bands of dynamic compression with selectable crossovers

  • 4 sections of parametric EQ plus an effective ‘Bass Punch’ feature

  • Independent ‘Density’ and ‘Smooth/Loud’ adjustments

  • GPIOs, Web/email/SNMP for controls and alarms

  • Built-in real time clock and headphone jack

  • Analog, AES-digital, streaming in/outs

  • Selectable US and international cutoff filters

  • A great ‘utility’ processor; ideal ahead of STLs/codecs

  • Full function 'responsive' Web interface works on desktop and mobile devices



Frequency Response (processing bypassed)

50Hz - 20kHz, ±0.25dB

Output Cutoff Response

  • Nominal Frequencies: menu-selectable 4kHz, 5kHz, 6kHz, 7kHz, 8kHz, 9kHz, 10kHz (US NRSC), 12kHz, 15kHz
  • Filter Characteristic: 143-coefficient FIR filter with phase and overshoot compensation; ±0.5dB, 50Hz to 0.95x nominal cutoff frequency; approx. –15dB at cutoff; > –50dB at ≥1.04x nominal.


Selectable flat, or ‘truncated’ US NRSC preemphasis curve scaled to the cutoff frequency

Distortion (processing bypassed)

  • Analog I/O: <0.02% THD (ref: +24dBu I/O)
  • AES Digital I/O: <0.002% THD (ref: 0dBFS I/O)

Signal-to-Noise (processing bypassed)

  • Analog I/O: >105dB (ref: +24dBu I/O)
  • AES Digital I/O: >120dB (ref: 0dBFS I/O)

Program Line Inputs

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

Program Line Outputs

  • Analog: active-balanced (XLR) delivers –12dBu to +15dBu for 100% symmetrical modulation; +24dBu clipping, 200Ω source

Positive Peak Enhancement

Intrinsic asymmetrical, positive-going peaks may be selectively limited in 1% steps from 100% to +130%

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 w/ assignable functions and logic polarity

Headphone Jack

Front-panel (TRS) 3.5mm

Internal Test Tone Generator

20Hz-20kHz; variable frequency and level


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.

Audio Processing

  • AGC: ±15dB capture range; gated with dual-rate‘windowed’ operation
  • Leveling: variable ‘syllabic’ 2:1 compression
