Mesa Boogie dual rec with impulse

[CAMILOGOD]

whats up, i wanted to use a dual rec amp with an impulse, i was wondering if theres any precautions i should take before plugging the amp into my soundcard and activating the impulse? I read something about hot plates but I'm not sure what those are, any help would be appreciated, thanks!

Make sure you have a Cab or some other kind of load like a Hotplate http://www.thdelectronics.com/product_page_hotplate.html connected to your Speaker Output and then do as you want safely.

I'm selling my Hot Plate right now as a matter of fact:

Almost brand new, works great. It's absolutely necessary to connect either (a) a cabinet or (b) one of these to your amp when you turn it on, or you will break your amp! Happy bidding!

And also, you'll wanna use the slave out when plugging into your sound card (cuz that's the straight pre-amp signal only) - having the cab/hot plate connected is just so the amp doesn't fry making all that power and having nothing to absorb it

thanks for the advice,
so if im right, the signal path is
dual rec slave out-->hot plate--->soundcard
??

 

[Metaltastic]

Nope - dual rec slave out --> soundcard

AND...

Speaker output --> hotplate or cab

 

[CAMILOGOD]

sweet, thanks alot man, one more question, which knobs are the ones that will be bypassed? and is there any way not to bypass them? or just use plugins for the knobs

 

[Metaltastic]

I'm not certain about what knobs the Recto has, but I know the presence knob wouldn't work cuz that controls the power section - basically, impulses capture the sound of a power amp, cab, and mic, so the only thing you wanna apply an impulse to is the preamp signal. But the channel gain and bass/mid/treble all should work, and actually, now that I think of it, don't 3-channel Rectos (if that's what you have) have presence controls for each channel?

If you turn on the FX Loop/Master Volume and keep the Master Volume at 0, you can have a cab connected with very minimal volume. Quiet enough for 3am, even.

On my JSX it's actually totally silent

 

[CAMILOGOD]

whats a jsx? is that a hotplate?

I'm pretty sure it's a Hot Plate AND a cab, not a Hot Plate OR a cab. It's an attenuator, not a dummy load. If you run the amp into a Hot Plate with no cab, you'll probably mess something up. 2012 is right about the loop. If you run your FX out into your sound card (watch the levels! start it out with the pre volume all the way down and just turn it up as much as you need), the amp itself should still be silent since there's no signal going into the power amp.

It's Peavey's Joe Satriani signature amp. It's a pretty good one, too!

There's only one company making the Hot Plate, and that's THD. Hot Plate is a brand name, not a type of product. This type of product is commonly referred to as an amp attenuator or dummy load. Gibson I believe makes a competing product but I've heard that the THD Hot Plate is much better, so it's what I went with. My Hot Plate is still up for auction, and much cheaper than new for what is basically new. If you buy it and need any help using it, I am Kazrog on AOL Instant Messenger as well.

I've never used one, but I'm almost certain that's not the case; if the Hot Plate weren't a dummy load, then I doubt it'd be nearly as popular!

"The Hot Plate® also makes a perfect dummy load." --from THD's site.

You'll notice that on the stepped attenuation knob on the front, "Load" is the lowest setting. I'm not sure whether you're to have speakers connected at that setting or not, but they won't make any sound, in any case.

 

[2012]

If your amp needs to be off standby, you'll need either a cab connected or a hotplate (or similar dummy load... you can even build a DIY dummy load with resistors). You don't need both.

If you have a cab and a master volume amp, you shouldn't need anything extra. As I said before, if you run the master volume on 0 with a cab connected, the volume of the cab is a whisper. Use the Slave Out or FX send to send the appropriate amount of preamp signal to your DAW.

 

[TomAwesome]

I stand corrected!

 

[CAMILOGOD]

thanks alot for all your help everyone who posted, my days of blowing amps are over

 

[CAMILOGOD]

i had just 1 more question, whats the difference betweeen a dummy load and a power atteunator?

 

[TomAwesome]

A dummy load takes place of a cab so you can run the amp without one. With an attenuator, you still need a cab, but it basically turns the volume down, so you can run your power tubes hotter without it being so loud.
