HD PRO TIPS

Recommended Posts

Hey guys I just recently came across a steal on an HD pro. I always wanted to toy with a digital modeling so I figured this one would be a decent way to get my feet in the water. I'm a huge noob when it comes to these amps so I was wondering if anyone could give me some tips to get this bad boy running. I'm currently using my peavey 5150 4x12 cabinet for my live shows and that is also what I am planning on running the HD Pro through. I also have a samson servo 150 power amplifier and was wondering if I could use that to power it? What cables am I going to need and what connections on the back of the processor am I going to need to use? My 5150 is Mono so that is how the HD is going to have to be ran. Thanks all for any feedback!

The connections are nothing mysterious.

Guitar--->HD--->power amp--->cabinet. I found a manual for that power amp online, and there are 1/4" outs, so there's no problem there. However at 75W per side, this thing is clearly designed for powering a pair of small near field monitors, not a 4x12 cabinet, as it also has connections (RCA? hard to tell from the picture in the manual) specific to some model of Samson monitors that they obviously intended you to use with it. The manual claims a 4 ohm impedance rating. You'll have to check your cabinet and see what it's rated at. Anything higher than 4 ohms, and you'll be losing power...and at 75 W per channel, it's already likely to be seriously under-powered for a 4x12 cabinet. What were you using to drive it before?

 

EDIT: I took another look...you can run it in bridged mono @ 8ohms, so that'll give you more juice. Might work ok, just depends on the impedance of your cabinet. Still not really designed for a guitar rig, though...no telling if it'll give you enough power to be heard over a drummer until you give it a shot. The claimed wattage on spec sheets is often "peak" power, rather than RMS (continuous) power, and thus is not always a good indicator of how loud the thing can actually get.

But the thing about modelers is: 

You shouldn't use them with a guitar amp. It doesn't matter how good a Fender model is, it will never sound like a Fender if it is played through a Peavey. Marshall will never sound like Marshall when played through a Fender. Guitar amps have a "personality", that is why we choose one over another. 

You're basically playing a personality through a personality resulting in a 3rd personality. Not necessarily a bad sound, just not the sound.

 

Sort of like looking at a picture with your eyes. And then using a red filter to look at the same picture. It looks very different. Blues are purple. Reds are white. Yellow is orange. Etc.

Agreed...but that's a whole other discussion, and I didn't have the strength this morning, lol. Figured it best to steer him away from what is likely an under powered amp for a completely diffrent application first.
