They are unbalanced Hi-Z (High impedance). Its a different animal altogether.<br><br>Thats why many interfaces have a separate guitar mode/switch.<br><br>-Chris<br><br><div class="gmail_quote">2008/5/27 Simon Williams <<a href="mailto:simon@systemparadox.co.uk">simon@systemparadox.co.uk</a>>:<br>

<br>
I often run the PA system for my CU at uni. So far we've been using<br>
jack-jack leads to connect guitars to the desk. However, my Dad has<br>
recently started using jack-XLR leads at my home church and says that<br>
it's much better.<br>
<br>
After a very long conversation and lots of googling (which incidentally<br>
provides no info at all on the subject), I'm now completely confused.<br>
<br>
Are guitars mic or line or what?<br>
<br>
The rationale for using jack-XLR leads and connecting to the mic input<br>
on the desk is that guitars have mics in them so they are mic level.<br>
Apparently the battery unit in the guitar doesn't make it line level,<br>
but I'm not convinced.<br>
<br>
The other thing I don't understand is that if that is the case, why do<br>
people use DI boxes? A DI box takes a high impedance (line level - I<br>
think) input and converts it to low impedance output (mic level). If the<br>
guitar is mic level already then what's the point?<br>
<br>
Please, could someone shed some light on this because I'm now very confused.<br>
<br>
Thanks in advance.<br>
Simon<br>
