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:
- AGC (Automatic Gain Control):
- Gated and ‘windowed’ gain-riding AGC for maintaining consistent audio levels.
- Syllabic Consistency Leveling:
- Adjustable ‘syllabic leveling’ for ensuring consistent audio quality.
- Dynamic Range Compression:
- 3 bands of dynamic compression with selectable crossovers for controlling audio dynamics.
- 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.
- Peak Controller:
- Final peak controller to support asymmetrical carrier modulation and prevent splatter.
- 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.
- Input and Output Options:
- Accepts both program line and streaming inputs.
- Analog, AES-digital, and streaming in/outs supported.
- Monitoring and Alarms:
- Allows remote IP audio monitoring.
- GPIOs, Web/email/SNMP for controls and alarms.
- Built-in real-time clock and headphone jack.
- Utility and Compatibility:
- Selectable US and international cutoff filters.
- Suitable for use ahead of STLs/codecs.
