On 28 Nov 2007 at 7:51, David Haggett murmured decisively:
First Question
It (the DMX 6Fire) has a 6.3mm (i.e. 1/4 inch) mono microphone input with
built-in pre-amp which the manual claims to be good for a condenser mic. I
typically plug my electric guitar into this, but is quite a fine balancing
act between guitar and pre-amp volume controls to avoid clipping.
Should I have something in the chain to match impedance, or is the clipping
just because my pickup signal is too high? I can eliminate it by turning the
guitar or the pre-amp down but this can lose tone.
yes, DI box. your choice of active or passive, powered or pure
transformer, or variations of the above. but apart from the clipping you
will get some weird frequency response changes from the impedance
mismatch.
Second Question
The mic input feeds to Alsa PCM Inputs 5 and 6, but of course is just 2
identical streams. I have been recording the guitar to a stereo track using
both channels but wondered whether there was any benefit in doing this, or
whether it would be better:
* take a single input and split it to a stereo track?
* take a single input and record it as a mono track?
I would do this. less noise, less disk space, less load reading it back
for playback (makes a difference on my marginal harddrive setup, may not
affect everyone)
* take a single input and feed it to a mono-stereo
plugin and record
it as a stereo track?
