Led s colours
’
The led can makes many colours. If it’s off, it does not means that the pedals is off, but that the
phantom power is off and the effect loop is bypassed: the signal goes directly to the output after
the input’s preamp without going in the effect loop.
Blue :
The pedal send your mic’s signal to the effect loop.
Green :
Happens only when you play, if the preamp is clipping.
Light blue :
Case Blue + Green : the pedal sends the signal to the effect loop and is clipping when
you play.
Red:
The phantom power is turned on, but no signal is sent to the effect loop.
Pink :
Case Red + Blue : the phantom power is turned on and the pedal sends signal into the
effect loop.
White:
Case Blue + Green + Red : Preamp is clipping, phantom power is turned on, Fx loop is
engaged.
The sound engineer is (sometimes) hopeless
Before you got you Blow! A sound engineer would plug the output of your pedal to a direct box
and set the input gain on the mixing table. The output signal of you pedal was so low that
everything was fine, whatever happened. Also, it’s possible that the sound engineer was you...
The Blow ! Will change this behaviour : the sound engineer is no more completly the master of his
input gain on the mixing table and it can cause conflicts with the most stressed, incomptent or
narrow minded of them. But don’t worry, if you’re not sure of what you’re doing, the best thing is
to
let the PAD on
. (See section « what are these buttons »). In this case the Blow ! Will behave
like a mic directly plugged in your mixing table.
But the following problems can happen and cause conflicts between you and your sound engineer :
1- If you’re plugged into the mic input of a mixing table but your sound engineer find that the
signal to noise ratio is not the best (There’s this « ssssshhhh » in the P.A). This case can happen
with entry level mixing tables. Then, if you Blow ! gain is already near clipping and you can’t push it
further, you should remove the PAD and backup the gain a bit on the Blow ! And back it
completely down on the mixing table to avoid falling in case 2:
2- If you’re plugged into the mic input of a mixing table and the PAD is removed. But input of the
mixing table clips. There’s two solutions : either you lower you gain a bit on the Blow !. Or the
sound engineer uses the mixing table’s PAD if he has one. But then you can be back to issue #1.
3- Your sound engineer has plugged nothing, and seeing your setup he’d preferred that you
remove the Blow ! and rather plug your pedals to a direct box. Explain to him that :
- By default, it output at mic level. (When the PAD is on, and again, the PAD is on by default, if
you push down the PAD button, you’ll remove it!).
- Or it can output a +4dBu max if the PAD is removed.
If after telling this to him he’s still not convinced, then he is incompetent. Try to keep the Blow !
In your setup otherwise you might have to setup right again all your guitar pedals. Then plug it like
a mic and don’t forget to keep the PAD.
4- Your sound engineer is a nice guy : he plugged you into a line input ! Remove the PAD and
discuss with him if your gain level is good enough for him.
