Inverto IDLU-32L412-UNBRR-OPN is a programmable satellite LNB based on Unicable II technology and dCSS (Digital Channel Stacking Switch). It allows satellite signals to be distributed to up to 32 compatible tuners through a single coaxial cable, simplifying multi-tuner and multi-room TV installations.
The LNB supports EN50494 and EN50607 (JESS) protocols. In dynamic mode, compatible receivers can independently select transponders from the received satellite spectrum. Each tuner uses a dedicated User Band with a specific frequency. In static mode, selected transponders can be converted and combined into a common output signal for distribution to compatible receivers.
The Inverto IDLU-32L412 is suitable for installations with multiple televisions, multi-tuner PVR receivers and professional satellite distribution systems where existing coaxial cabling needs to be utilised efficiently.

Applications
- Satellite systems serving multiple receivers and televisions
- PVR receivers with multiple independent tuners
- Domestic multi-room installations
- Systems using Unicable II and JESS-compatible receivers
- Satellite signal distribution over existing coaxial cabling
- Professional installations in residential buildings and hotels
Advantages of Unicable II
- Reduces the need for a separate coaxial cable for every tuner.
- Supports up to 32 compatible tuners in dynamic mode.
- Supports both EN50494 and EN50607 protocols.
- Simplifies upgrades to existing satellite installations.
- In static mode, allows preselected transponders to be distributed to compatible receivers within the configured signal capacity.
Installation Notes
- Receivers must support Unicable/SCR or dCSS/JESS to use the corresponding features.
- In dynamic mode, each tuner must be configured with a separate User Band and the correct frequency.
- Receivers supporting only EN50494 can use User Bands compatible with that protocol.
- To use all 32 User Bands, a receiver or system supporting EN50607 (JESS) is required.
- The LNB is powered through the coaxial cable by a compatible receiver or, when necessary, a suitable power inserter.
- Check the mechanical compatibility of the LNB holder and the requirements of the satellite dish before installation.
