Default Re: LEFT - STEREO - MONO - RIGHT Switch

Should there be resistors (around 1K) in series with the inputs so the outputs of the source device aren't shorted together when switched to MONO? It's not an issue for line level outputs as they normally have significant impedance but could be for headphone outputs on MP3 players etc.
