- Main Features:
- A sensitive, DSP-based (SDR) receiver for the 162.400 to 162.550 North American weather band.
- Flashing-red front-panel alarms and rear-panel ‘tallies’ for WAT (1050Hz tone), Low Signal and Audio Loss.
- Balanced analog and AES-digital program line outputs are available simultaneously and may be used for re-transmission. Levels are independently adjustable.
- All receiver setup parameters are held in non-volatile memory.
- When issued, free firmware updates are easily installed in the field.
- Specifications:
- Tuning Range: 162.400MHz – 162.550MHz in 25kHz steps; AFC follows transmitter frequency errors.
- Antenna Input: 75-ohm F connector
- Sensitivity/SNR: 10dBμV for 40dB S/N; selecting the Mute option will silence the audio outputs with a Low Signal condition.
- Reception Mode: Narrowband FM (NBFM)
- Audio Bandwidth: –3dB, 300Hz – 3kHz with automatic dynamic bandwidth filter for poor reception conditions. Response is further tailored to optimize speech intelligibility.
- Speech 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.
- Front-Panel Red-Flashing Alarms:
- Alert Tone: The 676 responds automatically to the 1050Hz WAT tone.
- Low Signal: Alarm and reset trigger levels are independently adjustable relative to the RF signal level display.
- Audio Loss: Alarm threshold is adjustable between 0dB and –40dB, and the alarm delay interval is adjustable between OFF and 120 seconds.
- 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 350mA; a universal 90 - 240 VAC inline switching power supply is included with the INOmini 676 receiver.
- Mounting Options: An optional rack adapter accepts up to three INOmini modules in a 1U, 19-inch rack space. The 676 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
