 Broadcast
Audio Processing
Inovonics Model 222
Key Benefits
- “Audio mask” compliance processing that meets US and overseas AM
transmission specifications.
- Includes pre-emphasis, peak limiting and low-pass filtering.
- Available in several versions to satisfy NRSC and CCIR
medium-wave and all short-wave cutoff characteristics.
| The 222 was originally developed as a ‘post-processor’ to ensure
US broadcasters’ compliance with FCC-mandated occupied-bandwidth regulations. It
incorporates a fast, asymmetrical peak limiter, independent pre-emphasis-protection
limiting, and a very sharp-cutoff low-pass filter with proprietary overshoot control. The
222 finds ready application in a wide variety of AM broadcast situations. In addition to
the NRSC 10kHz cutoff for medium-wave AM broadcasting in the US, any high-frequency
protection characteristic between 4.5kHz and 15kHz can readily be accommodated to meet
other domestic and overseas needs. Though the 222 is intended to provide basic final
limiting, a ‘floating platform’ release characteristic yields sufficient program
dynamics compression that often the unit can be run ‘barefoot’ between the
console and transmitter with good results. |
Inovonics Model 235 - AM Transmission Processor
Key Benefits
- One-box audio processing for mono-AM broadcasting.
- Includes AGC, equalization, compression, limiting and low-pass filtering.
- NRSC-compliant and AMAX-certified.
| The Model 235 incorporates all audio processing needs for AM broadcasting
in a single, easy-to-use package. ‘Gain-riding’ AGC is followed by variable low-
and high-frequency EQ, 3-band compression, an asymmetrical, integrated limiter/clipper
peak controller, and a low-pass function that satisfies NRSC or other ‘audio
mask’ specifications. A rear-panel RS-232 data port allows the processing presets to
be programmed or updated by computer or modem; the necessary software is included. |
Inovonics Model 261 - Tri-Band / PWM
Processor For FM
Key Benefits
- All Digital Processing .
- AES/EBU In and Out.
- Easy Menu Setup.
|
|
| DESCRIPTION: |
The new 261 from Inovonics combines the three audio
processing functions of gated, gain-riding AGC, program dynamic range compression and
final peak control. The unit may be configured to provide a single basic function
independently, or to utilize all processing options for comprehensive program audio
control. This gives the broadcaster a simple, economical and unobtrusive means of
normalizing and controlling audio levels in an all-digital or mixed-signal plant.
The DSP-based 261 affords the same versatile functionality of its predecessor, the Model
260, which has enjoyed a product life of more than 20 years. The 261 presents additional
features, vastly improved performance, and ease of integration with today’s trend
toward an all-digital broadcasting facility.

Inovonics Model 264 - Quad Processor
Key Benefits
- A simple, multi-channel ‘utility processor’.
- Dual Stereo or 4 Mono Cahnnels - includes AGC, compression and limiting.
- Alarm Outputs
|
 |
| DESCRIPTION: |
The 264 hosts four separate and independent channels of
analog audio gain control. Used separately, the four channels are ideal for microphone
leveling or similar monaural applications, and channels may also be selectively linked for
dual-stereo or split mono/stereo program control.
The 264 operates entirely within the analog domain and utilizes colorless Class D (PWM)
technology for stable and transparent operation. It employs a unique combination of peak
and average response to program dynamics that delivers the gain-riding advantage of an
intelligent AGC coupled with the tight peak control of a fast limiter. This particular
combination of long- and short-term level correction normalizes the average-to-peak ratios
of diverse audio sources to a common and natural-sounding value, giving a consistent level
of subjective loudness without the need for excessive compression of program dynamics that
can promote listener fatigue.

Inovonics Model 708 - Stereo
Generator (Stereocoder)
- Standalone digital-synthesis stereo generator (stereocoder).
- Includes overmod protection, low-pass filtering and composite clipping.
- Accurate front-panel metering – outstanding specifications.
| The Model 708 is a standalone stereo generator intended for use with an
external FM audio processing system. (The Inovonics Model 255 is an ideal companion for
the 708.) The composite multiplex signal, including the stereo pilot, is generated with
digital synthesis techniques to assure optimum stereo separation without need for
calibration adjustments. Additionally, the 708 provides internal combining for one or two
SCA or RDS/RBDS subcarriers. This unit does not take the place of an FM audio processor.
Works best when combined with a 261. |
Inovonics Model 718 - "David
III" Processor / Stereo Generator
- Third-generation DAVID processing. Bigger, bolder, brighter.
- AGC, multiband compression/limiting, equalization, proprietary final limiting
and composite clipping.
- Still the essence of simplicity; easy to set up and use.
| "DAVID-III" combines comprehensive multiband audio processing
with a digital-synthesis stereo generator for unexcelled performance and great value.
Pulse-width-modulation (PWM) techniques ensure rock-stable operation and a very
competitive, yet effortless sound. Density and equalization adjustments allow the
broadcaster to tailor the 'signature' of the on-air sound.Proprietary PIPP final limiting
and an adjustable composite clipper guarantee full carrier modulation for any program
audio source or characteristic. |
