Inovonics' INOmini 223 is an audio processing powerhouse in a deceptively small package. Its versatile DSP-based design is userprogrammable to serve multiple broadcast applications without compromising any single one. The unit addresses the needs of NRSC-compliant AM broadcasting with a range of cutoff frequencies, TIS (Traveler's Information Service) advisories, monaural LPFM transmission, and analog SCA subcarriers. A full-range ‘Studio’ mode satisfies mic processing and general production needs. The INOmini 223 features gated and windowed gain-riding AGC, 3 bands of adjustable dynamic range compression with selectable crossovers and variable EQ, and tight ‘lookahead’ peak control. Pre-emphasis, with its own protection limiting, and overshootcontrolled output filtering are individually and specifically tailored to the service selected.

  • Ideal for: US/NRSC AM, Worldwide AM, Shortwave, US/Euro Monaural FM, TIS, and analog SCA.
  • Easy menu / jog-wheel setup from the front panel.
  • Performs AGC, 3-Band Compression, Peak Control, and Output Filtering specific to the selected application.
  • User-adjustable compression, EQ, limiting, and program density.
  • DSP ‘lookahead' limiting offers tight peak control without clipping.
  • USB connector enables fast firmware updates in the field.
  • Headphone jack
  • Operating Modes:
    • NRSC-compliant asymmetrical AM processing with 10kHz, 9kHz, 7kHz, and 5kHz
    • (9-pole Cauer) cutoffs.
    • TIS asymmetrical AM processing with 5kHz (9-pole Cauer) cutoff.
    • FM processing (monaural) with 75μs/50μs pre-emphasis and 15kHz (7-pole Cauer) cutoff.
    • SCA processing with smooth 5kHz (6th order Butterworth) cutoff.
  • Frequency Response:20Hz - 20kHz, +/-0.1dB in PROOF and Studio modes; all specialized applications conform to specified cutoff characteristics.
  • Distortion:0.02% THD in PROOF mode.
  • Signal-to-Noise:Better than 72dB below the limited ceiling level measured through an appropriate de-emphasis network.
  • Program Line Input:Active-balanced (XLR) analog input, accepts nominal line levels between -20dBu and +20dBu.
  • Program Line Output:Active-balanced (XLR) delivers output levels between -15dBu and +12dBu corresponding to 100% modulation; 200-ohm resistive source. A switch under the top cover inserts a 20dB pad in the output for transmitters requiring a low level input.
  • Latency:3.5ms - 4.5ms, depending on selected application.
  • Headphone Jack:Front-panel (TRS) 3.5mm.
  • USB Port:Front-panel connection for firmware updates.
  • Metering:Input / Output / AGC Gain / Compression / Limiting
  • Alarms:Flashing front-panel indication of audio loss and AGC out-of-range.
  • Power Requirement:12VDC at 200mA (2.1mm x 5.5mm coaxial); inline switchmode power supply included.
  • Mounting Options:An optional rack adapter mounts one, two, or three INOmini format units in a standard 19-inch, 1U rack space.
  • Size and Weight:1.6"H x 5.5"W x 5.5"D 4 lbs. shipping weight
