In another thread someone asked about hooking up BT To his amp. The amp has only 1 pair of speakers out and no headphone jack. I suggested a speaker switch box with impedance protection. I know if you run 2 pairs of 8 ohm speakers the impedance drops to approximately 4 ohms. My question is what happens when you hook up 8 ohm speakers to output #1 and a bluetooth transmitter to output # 2. What is the impedance of the BT transmitter and would this set up work with out damaging anything?I did read somewhere that the transmitter could be as much as 200 ohm load but can't confirm anything. Thanks in advance
