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.Main 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 tallies for program Audio Loss (silence sense) and stereo Pilot Loss (stereo/mono status).Conforms to the worldwide FM pilot-tone system; selectable 75s/ 50s de-emphasis.Specifications:Multiplex (MPX) Input: Unbalanced/bridging (BNC); 10k input impedance; requires 0.5V p-p minimum signalL/R Analog Line Outputs: Active-balanced (XLR), 200-ohm source impedance; +4dBu output at 0dB on front-panel meterAES Digital Output: Transformer-balanced (XLR), 44.1kHz sampling rate; 6dBFS output at 0dB on front-panel meterHeadphone Jack: 3.5mm (TRS) for low-Z or high-Z phones, fixed listening levelProgram Audio De-Emphasis: 75s/50s, selected with push-on jumpers under the top coverAudio Frequency Response: Follows selected de-emphasis characteristic 0.5dB, 20Hz to 15kHzNoise: (SNR re: 75kHz deviation)MONO: >69dB analog; >72dB, AESdigital.STEREO: >65dB analog; >65dB AESdigital.Distortion: 0.05% THD, 20Hz to 15kHz (analog/digital)Stereo Separation: >50dB 20Hz to 15kHz (analog/digital)Forced-Mono Operation: Enabled with a push-on jumper under the top cover.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.Mounting Options: An optional rack adapter accepts up to three INOmini modules in a 1U, 19-inch rack space, or the 514 may easily be fastened to any convenient surface with two small screws.Size and Weight: 1.6H x 5.5W x 5.5D; 4 lbs. shipping weight.
