I'm trying to find out if this workaround for the audio, and the fact that it has no limiter, and no individual volume controls on a single mike input, would work. It appears that since the ATT switches are per channel, meaning not global, one should be able to:
1) Plug a mike into CH1
2) Set the feed to CH1 & CH2
3) Set the volume, which I guess only works globally (?)
4) Turn on the ATT on CH2 only, giving that channel a pad of 20db (?) - that is unless the ATT is global as well
5) Edit out the spikes on CH1 replacing them with the safe channel's audio (CH2)
Can an owner of the XHA1 try this out for me? It seems logical that it would work, but given how illogical it is to have volume controlled globally when it's only one input feeding both channels, I want to make sure this workaround might work. Am seriously considering upgrading, and all my other concerns/questions have been met with positives, but this audio section is an issue that I cannot go into blind.
edit: It's occured to me that this will pretty depend on the block design....
If it's this, assuming CH1 & CH2 feed is selected....
MIKE IN >>>> CH1 IN >>>> CH2 (the mike feeds ch1, which in turn feeds ch2)
meaning, a serial feed, then it's a no go.
If it's this....
MIKE IN >>>> CH1 while simultaneously feeding
MIKE IN >>>> CH2
meaning a parallel feed, then it should work.
Only other workaround would be software based, getting Canon to make the +12 db audio gain setting non-global, or channel selectable as it were. You'd have to set your gain backwards (set safe channel first, then add 12 db to other channel) but, to quote "Three Kings", "it kinda works".
edit: Just got off the phone with Canon, and yes it is a serial design, meaning CH1 feeds CH2, as opposed to each one feeding individually, which means that my idea WILL NOT work. The tech agreed that it was a lopsided oversight, not allowing for setting a "safe" channel, or having a limiter - especially when compared to the rest of the features on the camera. He agreed that the quickest fix is going to be through software, and is going to pass up the suggestions. Until then, it's Y cables for everyone!!!
