Can I use a Y-cable, 1/4 inch TS male to dual 1/4 inch female to Mic In on SX900, and use both of my SM58S mics? ...
Hi mhack,
In theory you could use a Y-cable like this to run two mics on one mic input at the same time, but it's not recommended. In this case, the two microphones influence each other. If you turn off one of the mics using the built-in switch, the other one is also muted. The output impedance of the SM58, which is already relatively low at 300 ohms, is halved when two microphones are connected in parallel, which is also not ideal. And of course you can't control volume, EQ and effects separately either.
It should also be considered that there are often contact problems with 1/4 inch (6.3 mm) female cable jacks (which can lead to clicks or dropouts when used with microphones). If you want to accept the disadvantages described above, I recommend at least using normal (XLR female to XLR male) micro cables and connecting them to the SX900 via a "XLR female *2 to 1/4 inch TS plug" Y-cable to connect.
However, my general recommendation is to use an additional small
external Mixer, preferably with built-in effects.
By the way, you could also connect one mic to the SX900 in the normal way and connect the second mic to the SX900's
AUX IN via a small external mixer.
Hope this helps!
Best regards,
Chris
