Title: Zoom H2 and the Line-In sensitivity of it
Post by: carlito1980 on February 16, 2008, 10:49:50 AM
Hi everybody.

I am pretty new here and just got my Zoom H2 and my church Audio ST-11 with 9000preamp are on their way  :D Now I read that some of you complained about the high sensitivity of H2´s line-in when they connected a CD-Player with it.
Do you think the Line-in will stand pop/rock concerts with the CA microphone rig?
I mostly want to tape my friends band, but they play loud shows, but not THAT loud, that you gonna need earprotections.  ;)


Do you think my Zoomy will record without problems?

Thanx for all help!

If I'm right, the CA STC-11s have a -10dB mod on them so I'm pretty sure it'll be fine. Just don't turn the Pre-Amp all the way up to 30dB  :o  ;)

Ok thanx. I hope so  ;D But if it´s still too loud, can I use

this to reduce the volume without loosing quality?

To be honest, I really don't know.

It would probably work, but I don't know if it would cause any quality loss.

Anybody else?

you should be fine with just the church pre - it has knob to control the output level.

Thx, but has the 9000 a control to reduce the outputlevel?

Just a gut feeling, but I think you will be fine.  The mics will almost surely need some gain to run line in.  I didn't read that other post, but LINE-IN from a cd layer output is much hotter than a set of mics...

I have a some similar gear...  I have CA STC-11 > CA9100 preamp > R-09 line in, and I usually end up turning the gain on the preamp up most of the way.

I use my CA-11>CA-9000>H2-line in rig as a backup and sometimes as the primary rig for recording mostly blues bands. Some of them can get pretty loud (measured an average 114db SPL at one show) and I haven't run into a real problem yet that wasn't my own fault. Just give it some headroom if the music is very dynamic. From talking to Chris Church on the phone I gather that turning the gain on the CA-9000 to about 80% is fine. I had been running mine at about 50% and he suggested making the adjustments. YMMV

BTW, Chris has come up with a relatively simple mod for the H2 that will add a fair amount of flexibility to the H2. Basically you just put a jack inline for each pair of the internal mics. That way with a battery box you can run external mics, either two external pairs or one pair and one set of the internals. I don't think he has settled on a price yet or even if he is going to get into doing them. I'll definitely be trying it myself one day.

Any time you use a pad, you will lose some dynamic range, and the H2 line input already lacks enough dynamic range to take advantage of 24-bit recording. That said, rock music has a lot less dynamic range than you will get with the H2, even with substantial padding, so it will still sound ok.

I have a preamp whose lowest gain setting is +20dB (Beyer MV100) and so I find that I must use the -10dB pads on my microphones, as well as an additional pad at loud shows. I bought the Core Sound -11dB cable, and it works fine.
