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 0.1dB 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.
