Brief description of an FBC tuner

What an FBC tuner is, how its physical and leaf tuners work, and how the "connected" option links them.

Receivers such as the VU+ Solo 4K, VU+ Ultimo 4K and GigaBlue Quad 4K have FBC tuners. Don't assume you can only use Unicable with FBC tuners — the two technologies are separate and independent, though you'll achieve more by combining them.

How an FBC module works

  • An FBC unit/module consists of two tuners with physical connections plus six "leaf" tuners without physical connections.
  • The two physical connections can have different signal sources — e.g. one motorised, one fixed / DiSEqC switch (it doesn't matter which way round).
  • There's internal linkage between the tuners within the same module. When configuring tuners, the "connected" option lets you specify which tuner to piggy-back off — you piggy-back off the tuner that has a signal wire attached.
  • There's no linkage between FBC modules. If you have two tuner modules (four physical connections), each module must have at least one signal wire attached. Currently, only the Ultimo 4K can have more than one FBC module.
  • If using a Unicable LNB, the splitter can sit next to the receiver.
