Az első ügyben nincsenek a maximális bemeneti jelszintnek korlátai, a másodikban - a maximális szint a multiswitch minőség indikátora is. A Terra multiswitcheknél ez 100dBuV és csak 80dBuV a Satmatrixnek, vagy a Viper termékeknek. Az olcsóbb multiswitcheket nem használhatják ott, ahol a jelszintek nagy aránytalanságot mutatnak a rendelkező helyszíneken vagy kiterjedtebb hálózatokban. A multiswitchnél ilyen esetekben a másik csatornákon levő erős jel keresztmodulációt és különféle interferenciás zavarokat idéz elő, amely azonnal a képen is látható lesz.
