    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 ‘tallies’ 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.

    • 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 ‘tallies’ for program Audio Loss (silence sense) and stereo Pilot Loss (stereo/mono status)
    • Conforms to the worldwide FM ‘pilot-tone’ system; selectable 75μs/50μs de-emphasis
    • Specifications
    • MULTIPLEX (MPX) INPUT:Unbalanced/bridging (BNC); 10k input impedance; requires 0.5V p-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: ≥72dB; analog/digital
    • STEREO: ≥70dB; analog/digital
    • DISTORTION:≤0.05% 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.
