[Harp-L] Amp>DI box>PA

["John F. Potts" <hvyj@xxxxxxx>]

Some amps  (like the SWR Baby Baby Blue bass amp I've been using  
lately) have an XLR out so you can take a lo-z  line out to the PA  
without a DI box.  For long cable runs, (over 25 or 30 feet in  
length) lo-z is preferable because there's no signal degradation with  
a lo-z (balanced) signal like there is with a hi-z (unbalanced)  
signal.  Or so I've been told by sound techs who seem to know what  
they are talking about.

Btw, Rolls makes a nice little passive DI box that's very compact  
(smaller than a small guitar effects pedal and very light in  
weight).  It's certainly small enough to carry around if you need one.

Once upon a time, when i used to play through an Alesis QuadraVerb GT  
into the board, I taped a Rolls DI box into the back of my rack case  
with duct tape so it would be available to use if I had to make more  
than a 25' run to the board from the Quadraverb (which has hi-z  
quarter inch inputs and outputs).  Never used the Rolls very much,  
but it's a handy little device.
