Overview
Inovonics NOVIA 236 AM Audio Processor
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.
