English original

Understand the wiring: from socket to receiver

A coaxial cable carries the reception signal. HDMI sends the receiver’s picture and sound to the television. LAN/Wi-Fi connects the receiver to the network. A network cable replaces an aerial feed only for explicitly configured network services such as IPTV or fallback reception.

Satellite connection in a house

Section titled “Satellite connection in a house”
Dish with universal LNB through a SAT wall outlet to the receiver SAT IN, HDMI to television
A conventional satellite connection uses an F connector on the SAT input. The wall outlet must pass the satellite IF band and the required control signals. Enlarge wiring diagram ↗
  1. Shut down and disconnect the receiver from power before reconnecting coax cables. A stray braid strand touching the centre conductor can short the LNB supply.
  2. Find the correct input: SAT IN/LNB IN for satellite, ANT IN/CABLE IN for cable or terrestrial. LOOP OUT is not a second independent input.
  3. Use the SAT output of a SAT/TV/radio wall plate. Follow the labels and installation plan, rather than relying on connector shape alone.
  4. Connect receiver HDMI OUT to television HDMI IN and select that TV input.
  5. Connect LAN separately for updates, EPG imports and network features.

Several subscribers in a house

Section titled “Several subscribers in a house”
Four fixed Quattro LNB planes to a multiswitch, with separate cables to two receivers
A conventional multiswitch supplies separate subscriber cables. Connect each Quattro plane to the input with the matching label. Enlarge wiring diagram ↗

Quad and Quattro are different. A Quattro has fixed VL/HL/VH/HH outputs for a suitable multiswitch. A Quad has four switchable subscriber outputs. See LNB types.

Cable TV and terrestrial aerial

Section titled “Cable TV and terrestrial aerial”
Alternative paths: cable TV outlet to DVB-C or aerial to DVB-T2, each with HDMI to the TV
Two alternative direct connections. A shared socket does not turn a single hybrid tuner into two independent frontends. Enlarge wiring diagram ↗

Leave aerial power off for direct cable TV. A compatible active aerial may require 5 V. Follow the aerial instructions for passive or separately powered models. Combine cable and aerial only through a suitable switch, such as the SPAUN TAR 5.

Which drawing matches my installation?

Section titled “Which drawing matches my installation?”
Existing equipment Drawing and settings
Two satellite positions, two LNBs or monoblock DiSEqC switch
One cable with allocated User Bands Unicable/SCR/JESS
Motorised satellite dish Motor and USALS
Cable + DVB-T2 on a shared input SPAUN, both switching states

The drawings explain signal paths. Roof installation, earthing and bonding belong to the professionally designed aerial system; these illustrations are not installation plans for that work.
