514 INOmini FM Multiplex Decoder Inovonics

514 INOmini  FM Multiplex  Decoder de FM

The INOmini 514 from Inovonics is a standalone decoder for multiplex stereo FM signals. It accepts a demodulated FM baseband input and decodes the signal into 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 "counting" and selectable de-emphasis curves make the INOmini 514 an essential tool for professional applications where you need to decode and monitor a stereo baseband signal.

How To Measure Your Bust

With your arms relaxed at your sides, measure around the fullest part of your chest.

How To Measure Your Waist

Measure around the narrowest part of your natural waist, generally around the belly button. To ensure a comfortable fit, keep one finger between the measuring tape and your body.

514 INOmini FM


  • 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


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


≤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.
