Inovonics Novia 236

The Inovonics Novia 236 AM Audio Processor is specifically designed for medium-wave monaural AM broadcasting. It offers a range of features tailored to optimize audio quality and signal processing for this application. Here’s a breakdown of its key features and specifications:

Features:

1. AGC (Automatic Gain Control):
   • Gated and ‘windowed’ gain-riding AGC for maintaining consistent audio levels.
2. Syllabic Consistency Leveling:
   • Adjustable ‘syllabic leveling’ for ensuring consistent audio quality.
3. Dynamic Range Compression:
   • 3 bands of dynamic compression with selectable crossovers for controlling audio dynamics.
4. Parametric EQ (Equalizer):
   • 4 stages of parametric EQ for precise control over the audio signal’s frequency content.
   • Includes a selectable ‘Bass Punch’ feature for enhancing bass.
5. Peak Controller:
   • Final peak controller to support asymmetrical carrier modulation and prevent splatter.
6. Presets and Control:
   • 10 factory and 10 user-defined processing presets for simplified setup and operation.
   • IP interface for remote control using any PC or mobile device. SNMP operation supported.
7. Input and Output Options:
   • Accepts both program line and streaming inputs.
   • Analog, AES-digital, and streaming in/outs supported.
8. Monitoring and Alarms:
   • Allows remote IP audio monitoring.
   • GPIOs, Web/email/SNMP for controls and alarms.
   • Built-in real-time clock and headphone jack.
9. Utility and Compatibility:
   • Selectable US and international cutoff filters.
   • Suitable for use ahead of STLs/codecs.
