- 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 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 0.5V p-p minimum signal
- L/R Analog Line Outputs: Active-balanced (XLR), 200-ohm source impedance; +4dBu output at ʻ0dBʼ on front-panel meter
- AES Digital Output: Transformer-balanced (XLR), 44.1kHz sampling rate; –6dBFS output at ʻ0dBʼ 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
- Audio Frequency Response: Follows selected de-emphasis characteristic ±0.5dB, 20Hz to 15kHz
- Noise: (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: 1.6”H x 5.5”W x 5.5”D; 4 lbs. shipping weight.
