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 ʻtalliesʼ 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 ʻtalliesʼ for program Audio Loss
- (silence sense) and stereo Pilot Loss (stereo/mono status).
- Conforms to the worldwide FM ʻpilot-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.
