- Main Features:
- The INOmini 674 is a sensitive, DSP-based (SDR) receiver.
- Easy front-panel setup uses jog-wheel menu navigation with a large color-LCD display. Critical system menus are hidden.
- Balanced analog and AES-digital program line outputs have separately-adjustable levels and may be used simultaneously.
- Flashing-red front-panel alarms and rear-panel ‘tallies’ indicate Carrier Loss and Audio Program Loss.
- All receiver setup parameters are held in non-volatile memory.
- When issued, free firmware updates are easily installed in the field.
- Specifications:
- Tuning Range: 520kHz – 1710kHz in 10kHz steps, or 531kHz – 1611kHz in 9kHz steps
- Antenna Input: Transformer-isolated 50Ω (F) input; a passive outdoor loop antenna is optionally available.
- Sensitivity/SNR: 10µV for 50dB S/N; 1mV for 60dB S/N
- Audio Bandwidth: Selectable: 6kHz, 4kHz, 3kHz, 2kHz (approx. –6dB point)
- De-Emphasis: 0µs (flat) or NRSC ‘truncated’ 75µs
- Program Audio Outputs:
- 1. Balanced Analog (XLR) Left and Right (dual-mono) outputs are adjustable from –15dBu to +15dBu in 0.2dB steps.
- 2. AES Digital (XLR) output at 44.1kHz is adjustable from –30dBFS to 0dBFS in 0.2dB steps.
- 3. The Front-Panel Headphone Jack (3.5mm TRS) has adjustable listening level.
- Alarms: Carrier Loss and Audio Loss alarms feature adjustable triggers and timing. The front-panel LCD flashes a red warning when the alarm is triggered.
- Alarm Tallies: Individual open-collector NPN transistor outputs to ground are programmable for logic polarity.
- Power Requirement: 12VDC at 275mA; a universal inline switching power supply is included with the INOmini 674 receiver.
- Mounting Options: An optional rack adapter accepts up to three INOmini modules in a 1U, 19-inch rack space. The 674 also 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
