- The INOmini 661 is a sensitive, DSP-based (SDR) receiver for EBU Band III DAB and DAB+ digital radio broadcasts.
- Easy front-panel setup uses jog-wheel menu navigation.
- A large LCD display shows essential signal parameters, demodulated audio levels, alarm conditions and program related metadata. Critical system menus are hidden.
- Balanced analog and AES-digital program line outputs are available simultaneously; levels are independently adjustable.
- Flashing-red front-panel alarms and rear-panel ‘tallies’ indicate DAB Loss, Low Signal and Audio Loss.
- All receiver setup parameters are held in non-volatile memory.
- When issued, free firmware updates are easily installed in the field.

Program Audio Outputs
- Balanced Analog (XLR) Left and Right 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
- DAB Loss: Fixed metrics determine loss of digital radio reception.
- 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 PortThe front-panel mini-USB port allows the quick uploading of firmware updates when issued.
Power Requirement12VDC at 335mA; a universal 90 - 240 VAC inline switching power supply is included with the INOmini 661 receiver.
