  • Inovonics’ INOmini 514 is a standalone decoder for FM-stereo multiplex signals. It accepts a demodulated FM-baseband input and decodes the signal to discrete left and right channel audio. The recovered stereo program is available as a professional line-level balanced output, and also as an AES digital audio signal.Local alarm Ê»talliesʼ and selectable de-emphasis curves make the INOmini 514 an essential tool for professional applications wherever a stereo-baseband signal needs to be decoded and monitored.
    Product Features
    • Decodes Composite/MPX signal into L/R audio.
    • Analog L/R and AES-digital program line outputs.
    • Accurate front-panel metering.
    • Front-panel alarms with rear-panel Ê»talliesʼ for program Audio Loss 
    • (silence sense) and stereo Pilot Loss (stereo/mono status).
    • Conforms to the worldwide FM Ê»pilot-toneʼ system; selectable 75μs/50μs de-emphasis.
  • Specifications
    Multiplex (MPX) Input:  Unbalanced/bridging (BNC); 10k input impedance; requires 0.5Vp-p minimum signal. 
    L/R Analog Line Outputs: Active-balanced (XLR), 200-ohm source impedance; +4dBu output at ‘0dB’ on front-panel meter.
    AES Digital Output: Transformer-balanced (XLR), 44.1kHz sampling rate; –6dBFS output at ‘0dB’ on front-panel meter.
    Headphone Jack: 3.5mm (TRS) for low-Z or high-Z phones; fixed listening level. 
    Program Audio De-Emphasis:  75µs/50µs, selected with push-on jumpers under the top cover.
    Forced-Mono Operation:  Enabled with a push-on jumper under the top cover. 
    Audio Frequency Response:  Follows selected de-emphasis characteristic ±0.5dB,20Hz to 15kHz. 
    Noise (Unweighted SNR re:±75kHz deviation):  MONO: t72dB; analog/digital
      STEREO: t70dB; analog/digital 
     Distortion:  d0.05% THD, 20Hz to 15kHz (analog/digital)
     Stereo Separation: >50dB 20Hz to 15kHz (analog/digital) 
     Alarm Tallies:  Individual open-collector NPN transistor outputs for Program Audio Loss (either/both channels) and Pilot Loss (stereo/mono indicator) 
     Power Requirement: 12VDC at 230mA. A ‘wall-outlet transformer’ (WallWart®) switching-type power supply appropriate to the destination AC mains voltage is provided. 
     Mounting Options:  An optional rack adapter accepts up to three INOmini modules in a 1U, 19-inch rack space. Alternatively the 514 may easily be fastened to any convenient surface with two small screws.
     Size and Weight:  1.6”H x 5.5”W x 5.5”D; 4 lbs. shipping weight.
