The Johansson 9337 is an analogue/digital priority switch designed for satellite IF signal distribution systems. It allows a designated priority receiver to take control of the LNB power and DiSEqC signals, overriding a secondary receiver when the priority input is active. The switch passes LNB control voltages (13 V / 18 V) and 22 kHz tone through the by-pass path, so the secondary receiver continues to operate normally when the priority receiver is not in use.

With a frequency range of 950–2150 MHz and a compact 60 × 50 × 16 mm body, the 9337 integrates into existing satellite distribution installations without rerouting main signal paths.

Product Benefits

• The priority switching function lets one receiver take precedence over another automatically based on voltage, eliminating the need for manual switching between connected receivers
• By-pass controls for 13 V, 18 V and 22 kHz ensure the secondary receiver retains full LNB polarisation and band switching capability when the priority receiver is inactive
• LNB current support up to 500 mA accommodates a wide range of LNBs, including multiswitches and Quattro LNBs with higher current draw
• Insertion loss below 3.5 dB keeps signal degradation minimal in the active signal path

Why You'll Love It

• The automatic voltage-based priority switching removes any need for the user to manually select between connected receivers — the switch manages itself
• At 60 × 50 × 16 mm, the 9337 is small enough to mount discreetly near the multiswitch or behind a receiver without occupying significant space
• Johansson's established presence in European satellite distribution means this unit is designed for long-term compatibility with standard European IF distribution architectures
