Hi BB,
as always many thanks for responding
the amplifier in the wireless is a bka300-4 and not the bka1000. Not that this should make any difference I believe.
i tried a number of configurations
1, used the y-splitter to connect into sub and rf transmitter first, the y splitter goes into sub output on my da5400es.. Result :sound through sub but nothing received at buttkicker.
2, checked the transmitter and receiver were synced. Believe they are, repeated test 1 no difference.
3, swapped the cables on the y-splitter, ie to prove no issues on the y splitter. Got sound through sub on both connections, nothing at buttkicker
4, decided to eliminate the wireless and wire direct to bka300-4. Again didn't work?
that said I do see some feedback, quite literally e.g you know if you hold the end of the RCA into a powered sub and it booms, on the transmitter for the buttkicker there is a left & right socket, the manual doesn't state which input to connect the sub to. At one stage I discounted from the left socket to plug into right. In doing so, when the connector nearly out the buttkicker vibrated immensely, similar to sub booming when you hold the end. So it indicated that the wireless if does work. But if you push the connector in fully nothing, in either socket?.
can you think of anything else for me to try?
