I had, like many other buyers here the situation that I wanted to connect a Twin Tuner Receiver, however, from the attic to the living room, only one cable is laid. Run through a second cable is very difficult and expensive. I thought to myself at any rate, if the Stacker works, I can save the additional installation and ordered the Johansson.
So connected the Stacker in the attic (for a multi-switch), then in the living room (right on the satellite wall socket) also. Since I do not have a twin tuner receiver, I took two single-tuner receiver for testing. The first was connected to the Rec1 port. The funkionierte immediately. Now the second receiver connected to the Rec2 port. And ... nothing ... no signal. Thought the part (or the second connection is broken).
However, as fast as I would not give up: therefore entered a few frequencies in the receiver and start channel search. Behold, the frequency was found suddenly. Then (although all always write, the power supply is not needed) I put to test the power supply but a. And suddenly he found all the other frequencies (the receiver not previously found) and all stations were right there.
Whatever the reason I need the power supply, now everything works as I wanted and the purchase of the twin tuner receiver will be at hand.
By the way, signal strength and signal quality of the signal of the terminal on Rec1 was by turning on the power supply significantly better with me.
