Inovonics 236 :: NOVIA AM Audio Processor

Inovonics 236

Features

Gated and ‘windowed’ gain-riding AGC

  • Unique, adjustable ‘syllabic leveling’
  • 3 bands of dynamic compression with selectable crossovers
  • 4 sections of parametric EQ plus an effective ‘Bass Punch’ feature
  • 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

  • AGC: ±15dB capture range; gated with dual-rate‘windowed’ operation
  • Leveling: variable ‘syllabic’ 2:1 compression
  • EQ: 4-section parametric
  • Bass ‘Punch’: variable bass enhancement

Power Requirement

12VDC at 240mA (2.1mm x 5.5mm coaxial); inline switchmode power supply included

Mounting Options

An optional rack adapter mounts one or two NOVIA or other Inovonics half-rack units in a standard 19- inch, 1U rack space.

Size and Weight

1.6”H x 8”W x 6”D; 5 lbs shipping weight
