Is standby enough to change impedance?

[Nico]

If I wanted to change impedance or plug other cabs:

I was wondering if I can just switch the amp to standby mode, change impedance settings (Plug in or out other cabs) and then switch the amp back off standby? While not having to turn the amp completely off...???

I always turned the amp completely off, but I am expeimenting a lot with different cabs and stuff, and needed a faster way of doing it...

 

[Peter Diezel]

Yes

 

[Nico]

Yes

That is good news for me... Thanks again Peter!

es reicht doch auch nur auf mute zu gehen oder den master auf 0 zu setzten?

noch ein paar fragen an den meister:
-soll man eher auf mute oder standby gehen bei pinkelpausen (5-15min, nein bei uns raucht keiner^^) bei der bandprobe?
-ist es besser den amp bei einem Gig immer wieder ein- und auszuschalten zwischen soundchecks und konzert oder auf standby oder auf mute?
-wie wäre es mit einer kleinen ungefähren abschätzung, wann man den amp auf welchen modus schaltet, z.B. mute bis 5min, standby bis 20min, ausschalten bei über 20min? das alles wenn der amp seit längerem am gleichem ort steht, natürlich.

danke schonmal! ich übersetzte auch alle infos ins englische!

Ehrlich gesagt .... in meiner Werkstatt stecke ich
einfach nur die Boxen um. In diesem Augenblick
halt nicht laut spielen. Kommt ein Signal und man
hat den Stecker in der Hand, kann´s noch einen
auf die Griffel geben. Also.... ICH EMPFEHLE ES
NICHT !!!

Bis 30 Minuten Pause auf Standby. Bei einer
Stunde dann schon ausschalten. Der Sound
verändert sich in den ersten 30 Minuten aus dem
Kaltstart, deshalb am besten eine halbe Stunde
vorwärmen.

Beste Grüße,

Peter

Danke für die mal wieder superschnelle Antwort!

So for our English-reading Diezel-family:

When changing cabs, switch on to Mute.
When not playing the amp up to 30min, you can leave it on Standby.
When the pause is longer, turn the amp off, but for tone stability make sure it has 30 min to warm up.

You have 4 switches in the amp...

Mains ON & Mains OFF
Standby & Run

What do you mean by mute = standby?

What do you mean by mute = standby?

The herbert has a mute-button

As I am not able to understand Germany please confirm this information:

Leaving the amp on (= Run) and engagin "mute" is enough for disconnecting the load (= changing cab)? As far as I know one should turn the amp to Standby, but that's why I am asking.

This is not a big deal for me (esp. as I am not owning Herbert), but Im just curious how is this possible if it is.

This. Is it true on vh4 and herbie?

Someone should put all this useful information in the manual.

 

[glassjaw7]

Yes

Peter, is this true of all amplifiers, or only yours? Thanks.

In standby, there is no B+ or high voltage running through the amp. The only thing that gets power are the tube filaments/heaters. So, you should be safe unplugging the speaker/load and switching cabs.

I know this is true = removing the load while amp in standby is OK.

But there was also a statement above that leaving the amp on MUTE is enough for removing the load. Personally I have serious doubts on the accuracy of this statement and thus hope someone would prove it to be correct or incorrect before anyone who has read it blows his amp's output trannies.

I believe the main thing is that there is no signal (i.e. the amp is still at idle) when the mute it activated. So, while it's not ideal the transformers can probably still stand up to the abuse of switching cabinets with just the mute function.

HOWEVER, why anybody would rather hit the mute button instead of the standby switch is beyond me. Standby is probably safer, just to be sure, than using the mute function. And they are basically right next to each other. So... if you're gonna hit the mute button, why not just hit the standby switch instead? Too lazy to move your finger another inch?

I think you are right with your statement above. Personally I never remove the load on my own amps with only engaging mute, but usually I turn the entire head off for this. So for me this conversation is not a big deal as such, but the reason why I keep rising this question again and again is to avoid that none manages to do any harm for his/her amp by acting inappropriate way.

Yes

 

[Ventura]

Yes

Peter, is this true of all amplifiers, or only yours? Thanks.

Yes

But the question remains that it's still better to use STANDBY rather than MUTE to swap out cabs, correct? MUTE is great for swapping guitars or stomps or the signal chain, but it's not stopping the need for load from the transformers - that's the job of STANDBY and RUN.

Just clarifying...

Happy new year, bro

Yes, the amp should be on standby.
So no plate voltage on the power tubes.

Thanks Poppa!!

And to you and Sawaki, a great start to 2011...!!

Auf Wiedersehen!
