Hi,
Newby here. I need to split the connector coming out of a jamhub into two or three so I can increase the number of remotes that can be used. If a y cable is used the power is too low so I expect that for each of the channels I will need to use an opamp to increase the signal strength. Would a TL084 be able to do this? Would I use signal ground instead of earth ground?
I tried to come up with a circuit, but I have no idea how to match the impedance so don't know what resistor values to use. If I duplicate the 4558 circuit with the TL084 would that do it?
Thanks,
Ian

The NE5532AP would drive 600 ohms total load. Just replace the 4556 dual with the NE5532 dual.
Same pinouts.

Can you sketch the complete circuit for the first op amp, leaving out the connectors
but adding the rest of the circuitry? Seems like there are problems.
OK, you got the input; but the op-amp can not feel the DC on its output. That cap blocks it. I don't think that cap is even needed.
