Re: iRig pre

I did further testing last night, and decided to take another approach this=
 morning. Instead of starting from low level (2 or 3) on the LS-10, I set i=
Rig to minimum and maxed Olympus to 10. I then slowly increased gain while =
studying the signal level on the Olympus. I then compared recordings using =
spectogram view on Audition. Although not particularly scientific, I'm of t=
he opinion that this method produces quieter results. I need to re-do the l=
ast test tonight to confirm my opinion. I would really love for one of our =
techy sound specialists to get hold of one of these and test. The weather i=
n the UK at the moment is pretty horrendous, and it doesn't look like I'll =
 be getting out to record wildfowl coming into roost within the next few da=
ys. I can't wait to try this out in 'the field'.
Cheers
Max

 If I did understand that you're using the headphone OUT on the iRig, then =
I'm confused, because I thought I'd read somewhere that the headphone OUT w=

 I'm not that well educated in this area, so I probably got it wrong.

quite impressed with the iRig pre. I tried it using my only remaining AT303=
2 (really wish I hadn't sold my other two!) and the quality improvement ove=
r the internal mic of my iPod Touch was obvious. Most obvious was loss of l=
ow frequency random noise, in addition to the obvious benefit of gain. My s=
imple tests were using my 66 year old ears, which aren't that good, so take=
 this as you will; I'm sorry it's not more scientific. What I intend to do =
next is to try the beast with my LS-10 after buying/making an adapter.

 yesterday with my LS-10. This time, I used the low setting sense setting a=
nd then upped amplitude by 6db in Audition. The results certainly confirmed=
 what Umashankar said; this is a really good quality, quiet and useful set =
to carry (shotgun CP4 with very narrow super cardioid pattern; omni and car=
dioid shorts). Whether or not I'd be prepared to pay the asking price I've =
seen on eBay USA sometimes, I'm not sure, but if any of you get the chance =
to pick one up cheaply, I'd say don't hesitate. The only downside is that t=
he batteries are not cheap, but according to Umashankar it's posssible to c=
onvert to phantom power.
