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. In addition to quick and easy frontpanel setup, 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. Program audio failure alarms trigger local tally closures and instantly dispatch SMS/email notifications to selected personnel. Alarms are also logged for later analysis. Setup and operation are simplified with 10 factory 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 setup and control of the unit from your PC, tablet or smartphone.

• 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

Specifications:

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.

Pre-Emphasis

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

Alarms

Local (GPIO) closures, browser interface, SNMP and SMS/email alarms for analog, digital and stream audio loss; maintains daily, weekly, monthly logs

Scheduler

Dayparting is simplified with an onboard real-time clock and preset-selection programming.

Audio Processing
