5 x 4 dSCR (Sky Q) Switch - Add to IRS or Stand Alone. Line Powered.

Vision IRS switches have been the UK market leader for more than a decade, proving to be exceptionally reliable and versatile. Often copied but never equalled, the features are extensive, the power consumption low, noise low and interconnectivity completely flexible. Availed with Sky Q and Sky+ commutability, even the oldest installations can support our new Sky Q adapters, keeping your investment future proof. These products include factory fitted earth bars, stepped high gain outputs for multiple drop cable lengths up to 50m, variable gain control, power from anywhere - even no landlord supply installations. Colour coded, screened and filtered for interference rejection, these products represent excellent value for money. Free system design service included.
