2 into 1 Cornet
« on: 12 Aug 2013, 06:45 pm »
Hi folks.
I fancy adding inputs for a second turntable to my Cornet.  How problematic is it going to be switching between the two, and are there any good ways of doing it?

Thanks Tone

It is possible, but not without some drawbacks.
I'd use some good relays for that, but this incurs some circuit to control them. The main advantage of the method is known contacts performance to chose (due to the necessity to switch very low currents).
Good switch (like used in the Piccolo) can do the job also.

Doable, but I would avoid adding any circuitry to the C2.  Phono stages amplify very low level signals.  Additional wiring and/or switches just increase the possible injection for noise into the circuit.  Why not just switch the cable to change TT's?
