236 NOVIA Inovonics

236 NOVIA AM Mono Inovonics

NOVIA AM audio processor: DSP 3-band Mono AM | Analogue, AES, Streaming In & Out | NRSC | Web interface

NOVIA 236 is specifically designed for medium wave monophonic AM transmission. It combines the functions of slow AGC, `` gain-riding'', `` syllabic consistency levelling'', 4 stages of parametric equalisation, 3 bands of dynamic range compression with variable crossovers, `` brick wall'' bandwidth limitation and a splash-free final peak controller that supports asymmetric carrier modulation. In addition to quick and easy front panel configuration, the IP interface allows streaming of 2-way programs, as well as full remote control of NOVIA 236 using any PC or mobile device.

SNMP operation is supported. Program audio fault alarms activate local counting closures and immediately send SMS/email notifications to selected personnel. Alarms are also recorded for later analysis. Setup and operation are simplified with 10 predefined and 10 user-defined processing presets.

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

The 236's web interface will allow complete configuration and control of the unit from a PC, tablet or smartphone.
