Inovonics INOmini 223

Multimode Audio Processor

The Inovonics INOmini 223 is an audio processing powerhouse in a deceptively small package.

Original price was: €1,075.Current price is: €1,025.


The Inovonics INOmini 223 is a versatile multimode audio processor designed to address various broadcast applications including NRSC, AM, FM, SCA, and TIS. Here’s an overview of its features and specifications:


  1. Versatile DSP-Based Design:
    • User-programmable to serve multiple broadcast applications including NRSC, AM, FM, SCA, and TIS.
    • Ideal for studio use, US/NRSC AM, worldwide AM, shortwave, monaural FM, TIS, and analog SCA.
  2. Audio Processing Capabilities:
    • Parametric equalizer with continuous control over frequency content.
    • Three bands of dynamic compression with selectable crossovers.
    • Gated and windowed gain-riding AGC.
    • Tight ‘lookahead’ peak control.
    • Variable EQ and pre-emphasis with protection limiting.
    • Output filtering tailored to the selected service.
  3. User-Friendly Interface:
    • Easy menu/jog-wheel setup from the front panel.
    • USB connector for fast firmware updates in the field.
  4. Monitoring Options:
    • Headphone jack for monitoring.


  1. Operating Modes:
    • Supports various processing modes for NRSC-compliant AM, TIS, monaural FM, and SCA.
  2. Frequency Response:
    • 20Hz – 20kHz, ±0.1dB in PROOF and Studio modes; specialized applications conform to specified cutoff characteristics.
  3. Distortion:
    • 0.02% THD in PROOF mode.
  4. Signal-to-Noise Ratio:
    • Better than 72dB below the limited ceiling level measured through an appropriate de-emphasis network.
  5. Program Line Input:
    • Active-balanced (XLR) analog input, accepts nominal line levels between –20dBu and +20dBu.
  6. Program Line Output:
    • Active-balanced (XLR) delivers output levels between –15dBu and +12dBu corresponding to 100% modulation; 200-ohm resistive source.
  7. Latency:
    • 3.5ms – 4.5ms, depending on selected application.
  8. Headphone Jack:
    • Front-panel (TRS) 3.5mm.
  9. USB Port:
    • Front-panel connection for firmware updates.
  10. Metering:
    • Input/Output/AGC Gain/Compression/Limiting.
  11. Alarms:
    • Flashing front-panel indication of audio loss and AGC out-of-range.
  12. Power Requirement:
    • 12VDC at 200mA (2.1mm x 5.5mm coaxial); inline switch-mode power supply included.
  13. Mounting Options:
    • Optional rack adapter for mounting in a standard 19-inch, 1U rack space.
  14. Size and Weight:
    • 1.6”H x 5.5”W x 5.5”D; 4 lbs. shipping weight.
  15. Environmental:
    • Continuous operation at ambient temperatures between 32ºF/0ºC and 122ºF/50ºC; 0-95% relative humidity, non-condensing, altitudes to 10,000ft/3,048m.

The Inovonics INOmini 223 offers a compact yet powerful solution for audio processing in various broadcast applications, providing flexibility and high performance in a small package.
