- Main Features:
- 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.
