Small things that most pepole don't know about the Shuttle 6.0

1. If you push the EQ, you're pushing the gain stage regardless of whether the gain knob clips when the EQ volume is flat. Your observation makes total sense since it's pretty much the way all amps with an EQ work.

2. As it should be.

3. Don't know anything about that, but I would imagine it would have to do with the freqs it boosts.

4. That's odd.

5. Post EQ means the EQ affects them. PRE EQ is what you're talking about.

6. That's actually good, IMHO. There are other ways to defeat the speaker, but if the headphone jack defeats the speaker, you don't get a choice of running the speaker while you use headphones or not.

 

So overall, do you like it?

Do you like the tone?

 

I do believe the OP is correct regarding post eq.

those signals, as I recall from the manual, are introduced after the eq, therefore post eq, and therefore unaffected by eq settings.

 

How could they be unaffected if they're introduced after the EQ? Let's say you have a bass, a separate EQ, and an amp, and you plug them together in that order. Once you plug into the amp, the EQ is going to affect whatever sound goes into the amp. If you boost 3K on the EQ, the amp is going to reflect it. Therefore the amp is post-EQ.

 

It only has speakon outputs- no 1/4 inchers. So if you're about to pony up for one- make sure you have a speakon lead in your arsenal.

 

Yes, but the fx return and/or aux in are discreet signals from the bass signal. In your example, the aux input would sum with the bass signal between the eq and the amplifier, therefore turning the eq knobs wouldn't affect the signal coming into the aux input, but it would the original bass signal.

 

If the EQ doesn't affect them, then they're pre-EQ. Pre = before, post = after.

 

I see how we're confused. That is how it works for outputs. It's the other way regarding inputs which is what the OP was referring.

In the case of an onboard DI, the pre-eq setting takes the signal prior to the eq, and post after, per your statement.

The guitar input in front of the amp is pre-(before) the eq, and is definately affected by it, as the eq is downstream of the guitar input. In the case of the aux input of the Shuttle, if I remember correctly, it is input downstream of the eq section, therefore unaffected by it.

 

Wha? You're not making sense.

 

He's saying that the effects send signal does not pass through the EQ section of the preamp - its wired in after EQ changes.
input->preamp->fx loop-> poweramp
rather than
input -> fx loop-> preamp-> poweramp

 

Yeah...that makes sense to me !

As to the OPs original list:

" 4. "Mute" button won't cut the volume ALL the way, you could still hear a very low signal. "

Thats not my experience; Mute button completely cuts the speaker signal. Do these buttons leak ?

 

+1

my mute is silent.

 

mine is silent as well.

 

the effects loop/eq thing bothers me too, on my GK 700RB. i use a pretty dark and fat tone overall, and the eq reflects that.
but, say i use a processor with some hiss or noise like you would expect---- if the eq was after the loop, some high end could be rolled off, which would (a) lessen the impact of the hiss, and (b) be perfectly acceptable to my sound as i already have those frequencies rolled off in the preamp.
though i dont think many amps are designed this way, i can see great benefit, at least in my application. i guess the opposite would be true if you used a very bright sound with lots of treble, as post-loop eq would be *boosting* the hiss. seems like a pre/post switch for the loop would be easy and inexpensive to add to a given design.

 

Not related to the amp itself, but to the pre/post effects loop. Why can't we have a selectable pre/post FX loop? It seems logical.

 

MY mute is dead silent as well, just checked it.

You might have a very light bleed through the button wiring itself or on the board, I'd call GB and ask them.

 

He's talking about inputs.

You are talking about outputs.

If the chain goes input -> EQ -> power amp and you have an aux input after(post) the EQ the equalizer will not effect it.
