KPA and 4x12 cab

theplayer · Oct 26th 2014

I connected the KPA sofar a pair of QSC K8 FRFR speakers. Sounds quite well.

But I have also a 300W Line 6 4x12 stereo speaker cab left from my Vetta amp days (looks more mature...). I connected it to Monitor OUT It really sounds like crap!! Also from main stereo outputs it's' crap(like an old radio)!
Then I read topics in which guys connect an Engl 4x12 speaker cab with blowing sounds. I guess those contain no FRFR speakers but really guitar speakers...

But in the profiled cabs there is no Engl 4x12 available. Am I missing the point here?

So my question: Can I connect such a Line6 4x12 stereo speaker cabinet with a blowing sound like a 4x12 Engl. And how to connect in the right way?

Do you have a kemper power rack/head?
What power amp did you use?
the profile makes a big difference also when using Guitar cab/speakers

Was the cab section on or rather of in each attempt?

theplayer · Oct 26th 2014

I have this one: http://www.4sound.dk/shop/guit…-amplifier-powerhead.html

I don't have a power amp. I don't need this, having a head...or am I wrong?

I don't understand your last remark. Does it mean that a random profile in the KPA doesn't combine with a 4x12 external cab?

I put the cab section on and choose for Mars 4*12 Green Pack...(but I'm still looking for cab sim off/on)

To turn cab sims on or off, simply click the 'cab' button on the KPA's front panel's center. Try it through the main outs until after you read the manual.

If you're using a powerhead, i'd keep the cab sims on. Bear in mind, this may or may not work.
Some profiles simply don't work well through guitar cabs. The sound will always be muted and mid-centric compared to your QSC - because that's what guitar speakers do - but some profiles just don't work with some cabs, just like some guitars don't work with certain amps.

But what is that on a topic with someone using a Marshall 4x12 with celestion G12t75's?
(see topic New Kemper owner today, reply on Sept. 4th from Lash, with picture! )

Found
the Monitor Cab off (System, page 3) OFF or ON makes no difference.
Still crap! I guess a good external 4x12 cab doesn't do the job...not in
Monitor output and not in Main output jacks.

Hey Player,

I had the same problem when I tried to connect my Powered Rack to my 4x10 cabinet using the Monitor Out.

I realized after a while that I was using the wrong output!

I believe you need to take the signal from the Power-amp to drive the speakers. On my unit is is labeled "Speaker Output" and the jack has a RED ring around it. Once I did that it sounded glorious.

I suppose you want to use a speaker cable but I'm not sure. Anyone else?

Also, When I use my 4x10, I just turn cabinets off in the Stack section, but if you want to use it on stage and send the full signal (cab profiles included) to the FOH, you should turn off cabs using Monitor Cabs Off.

If I am mistaken in any of this hopefully the experts will chime in and correct me!

Good luck.

Cal

Hmm...

You say you don't have a power amp, but then you said you own the PowerHead....and I assume that is the one with the built in power amp.

Like I said in my post above, look for the RED output jack that says Speaker Output. If you have that hopefully that will solve your issue.

And again, I think you want to use a speaker cable...not a regular guitar cable.

Lash · Oct 27th 2014

I have the powered version (power rack) and use a speaker cable out of kempers speaker output port to 16 ohm 4x12 cab. I leave cabs on for most rigs. And use the built in studio EQ in the X. The studio EQ and rig make all the difference when using Guitar cabs. (In my opinion).

Also I play loud
(volume usually around 6 or higher) and power amp at +6 db. It sounds Huge with the studio EQ set right and the volume turned up.

What profiles are you using or what is your favorite go to so far?

sambrox · Oct 27th 2014

I have the PowerRack and it sounds great through my old Marshall 1960 2x12 (and it's not even considered a great-sounding cab). As stated by Calaban, you need to use the power amp output, marked with red, and use a (decent) speaker cable. I ALWAYS use it with monitor cab sims off (in the output section), as I feel that the sound is always duller/thinner with cabs engaged through my 2x12.

Hope you get it sorted.
Cheers,
Sam

Thanks guys for your suggestions.
It sounds a bit better but all supporting fx are gone: no delay, no reverb etc. It's just a dry signal. I have Monitor Cabs sims off (OUTPUT) Master Volume is not working, only Volume. It's not breath taking...I'm sorry.

Connections: (switch to 16 Ohm cabinet)
Speaker output KPA provided with http://www.moretronics.nl/cata…s8gf4q530q0iad6rlsqqiro15
From there 2 real speaker cables (something like this http://uk.rs-online.com/web/p/…re-speaker-cable/7140300/ ,with good Neutrik NP2C jacks) to stereo cab Lin6 6 (300W)

master: you shall link your master to the speaker/monitor output --> in the output section
effects: you shall set monitor out to "master mono" --> in the output section

regarding your cab, if I saw right, you have cab with 2 x 8 ohm. If you connect it as you did – with Y-splitter, you connect it in parallel, so the load is 4 ohm (not 16 ohm). Perhaps can you set your cab at 16 Ohm mono and connect it with only one speaker cable (not guitar cable). And, speaker out on Kemper (red output, says 8-16 Ohm) is MONO, so it is not possible to play stereo with built-in-power amp (only with separate stereo power amp)

theplayer · Oct 28th 2014

Hopefully I understand this right:

OUTPUT Page 1 Output source: Monitor Output set to Master Mono (that would be for the fx)

But on this page I see no Master to link

The Kemper sounds great to my ears, but i can't say for yours. There are so many variables here - greatest of which would be your taste, style and profile used. The best we can do is help make sure everything is set up right - but if you really don't like the Kemper, get rid of it.
