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.
Unbalanced/bridging (BNC); 10k input impedance; requires 0.5V p-p minimum signal.
Active-balanced (XLR), 200-ohm source impedance; +4dBu output at ‘0dB’ on front-panel meter.
Transformer-balanced (XLR), 44.1kHz sampling rate; –6dBFS output at ‘0dB’ on front-panel meter.
3.5mm (TRS) for low-Z or high-Z phones; fixed listening level
75μs/50μs, selected with push-on jumpers under the top cover
Enabled with a push-on jumper under the top cover
Follows selected de-emphasis characteristic ±0.5dB, 20Hz to 15kHz
≤0.05% THD, 20Hz to 15kHz (analog/digital)
50dB 20Hz to 15kHz (analog/digital)
Individual open-collector NPN transistor outputs for Program Audio Loss (either/both channels) and Pilot Loss (stereo/mono indicator)
12VDC at 230mA. A ‘wall-outlet transformer’ (WallWart®) switching-type power supply appropriate to the destination AC mains voltage is provided.
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.
