Discription Specifications Video Inovonics 674 INOmini AM Broadcast Monitor Receiver/AM Broadcast. The INOmini 674 is Inovonics’ second-generation, small form-factor AM broadcast receiver for professional applications. It serves admirably as a ‘confidence monitor,’ and includes alarms to indicate transmission problems. At the same time it can deliver a high-quality audio feed for program distribution throughout the broadcast facility. Features The INOmini 674 is a sensitive, DSP-based (SDR) receiver for standard AM broadcasts. 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. 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 BandwidthSelectable: 6kHz, 4kHz, 3kHz, 2kHz (approx. –6dB point) De-Emphasis 0µs (flat) or NRSC ‘truncated’ 75µs Program Audio Outputs Balanced Analog (XLR) Left and Right (dual-mono) outputs are adjustable from –15dBu to 15dBu in 0.2dB steps. AES Digital (XLR) output at 44.1kHz is adjustable from –30dBFS to 0dBFS in 0.2dB steps. Headphone Jack (3.5mm TRS) has adjustable listening level. Flashing RED Front Panel Alarms Audio Loss: Alarm threshold is adjustable between 0dB and –30dB, the alarm delay interval is adjustable between OFF and 120 seconds. Low Signal: Alarm and reset trigger levels are independently adjustable relative to the RF signal level display. Alarm “Tallies”: Individual open-collector NPN transistor outputs to ground are programmable for logic polarity USB Port The front-panel mini-USB port allows the quick uploading of firmware updates when issued. Power Requirement 12VDC at 275mA; a universal 90 – 240 VAC 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
