INTRODUCTION
Product Description
Inovonics’ NOVIA 236 is a compact and versatile airchain
processor for monaural AM broadcasting. A wide range of
transmission bandwidth choices and audio processing op-
tions makes the NOVIA 236 well suited to standard medium
wave, shortwave and specialized AM broadcast services.
The NOVIA 236 features gain-riding AGC, leveling, paramet-
ric EQ, 3-band dynamic range compression, and asymmet-
rical wideband and independent high-frequency final limit-
ing. Programmable from the front panel or through its
cross-platform Web interface, the NOVIA 236 also supports
2-way program streaming and SNMP.
Product Features
Features of the Inovonics NOVIA 236 include:
Comprehensive audio processing with factory and
user presets; internal scheduler for dayparting
Accepts analog, AES-digital and streaming program
inputs
Analog and AES-digital outputs; out-streams source
and processed audio for remote monitoring
Failover feature can switch to an alternate program
feed when primary audio is lost
Easy setup using the OLED screen and jog-wheel nav-
igation of the processor’s menu tree
Full-function Web interface works with any browser
Self-logging alarms for audio loss; alarm ‘tally’ for
remote indication; dispatches email or text message
alerts
Accurate front-panel LED metering; all processing
functions metered with OLED display and Web inter-
face

Product Specifications
Frequency Response (processing bypassed):
50Hz-20kHz, ±0.25dB
Output Cutoff Response:
Nominal Frequencies:
5kHz, 6kHz, 7kHz, 8kHz, 9kHz,10kHz
Filter Characteristic:
143-coefficient FIR filter with phase and over-
shoot compensation; ±0.5dB, 50Hz to 95% of nominal cutoff fre-
quency; approx. –15dB at cutoff, >–50dB at 104% of cutoff
Pre-Emphasis:
None (flat response) or ‘truncated’ US NRSC pre-emphasis curve
scaled to the selected 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) monaural input accepts nominal
‘0-VU’ line levels between –15dBu and +15dBu; +24dBu clipping
AES Digital:
transformer-balanced (XLR) accepts peak line levels
between –30dBFS and 0dBFS at sampling rates from 32kHz to
96kHz; select mono-left, mono-right or L+R program audio
IP Streaming:
accepts Icecast/SHOUTcast MP3, Ogg and AAC streams
Program Line Outputs:
Analog:
active-balanced (XLR) delivers –12dBu to +18dBu for 100%
symmetrical modulation; +24dBu clipping, 200-ohm source
AES Digital:
transformer-balanced (XLR) delivers –30dBFS to 0dBFS at
100% symmetrical modulation; sampling rate follows input or may
be fixed at 32kHz, 44.1kHz, 48kHz, 96kHz
Positive Peak Enhancement:
Intrinsic asymmetrical, positive-going peaks may be selectively limited
in 1% steps from 100% to +130%
Program Signal Latency (Delay):
1.5ms in Bypass, approx. 3.7ms in normal operation
Network Port:
TCP/IP network connection (RJ45) for remote setup/operation and
in/out audio streaming; full SNMP support
GPIO Ports:
3 GPI, 3 GPO with assignable functions and logic polarity
Headphone Jack:
3.5mm (TRS) on front panel; low-Z or high-Z headphones
Internal Test Tone Generator:
20Hz-20kHz; variable frequency and level
