I'm sorry to say that sounds exactly like my unit, although mine is only making that noise through the rear inputs. Suggest contact Kemper support
G'day, follow this, you'll be fine (some page numbers referred to dont always match)
Tip: Use performance mode, not browser mode, switching has no lag and editing your rigs doesn't affect the original
I'm having a similar issue at the moment, I'm only getting noise through the rear inputs but fine through the front. You may well have a fault, but I'd suggest try different inputs if you can't afford to be without your amp at the moment
I must admit that I don't believe I've had any profiles sounding impressive through my HS8's either, although being that I have the power rack version, I'm extremely happy with a lot of the profiles through my 4x12 cab with celestions, although obviously every profile is coloured by the same celestion tone.
Gary Moore can get some awesome Soldano tones out of my HS8's, but I can't seem to do the same
I appreciate an expression pedal would be better, but I still wouldn't be able to set heel or toe values within the Kemper, ie delay mix on 1 rig between say 0% and 50 %, and then gain on the next at 20% and 70%, it would either be locked in the pedals settings or full range the whole time. I will soon get a Dunlop expression pedal, $200 in Australia, not exactly giving them away, but I'd probably want to continue using the volume pedal as a dedicated wah. Just hoping to get a bit more functionality out of the gear I'm currently using which seems to only be inhibited by software limitations at the moment
It seems that it is impossible for me to Calibrate an expression pedal (Boss Volume) that is connected through a third party midi controller (Voodoo Labs Ground Control). The pedal I am using is only sweeping 0~102 instead of 0~127 (this is the pedal's fault, not the Kemper).
On previous equipment I've used (TC Electronic G Force) I have been able to calibrate both heel and toe position as well as adjusting the curve of the sweep. I could also set a minimum and a maximum value, eg; if I wanted to move between 10% delay mix at heel and 50% delay mix at toe.
Although it is obviously possible for me to connect an expression pedal through my Ground control, (which is my preferred method as it means I only need 1 cable (midi) running from my rack) it seems I'm only able to get less than optimal functionality using this method where as other units (G Force) can make this method work 100%.
I'm using a Boss Volume pedal, I understand this isn't recommended and would never be a preferred option, but it does work fine with other gear/software.
One benefit to running a pedal via midi rather than through the pedal inputs is that I control a lot more parameters, ie; gain, delay mix and others that currently aren't possible through the Kemper pedal inputs without morphing, I'm just not getting the accuracy or control that I would like.
Otherwise, loving the Kemper, it's literally magic in a box!
Just found this in an older thread, I was wondering the same thing:
"While we are recommending 8 or 16 Ohm cabinets in combination with our built-in power amplifiers, it is techncially completely safe to use 4 Ohm cabinets.
However users should be aware of some facts and apply the following best practices.
Normally the built-in power amplifier would deliver significanty more power loaded with a 4 Ohm cabinet. But its power output
is technically limited to 600 Watt, which is exactly the maximum it can deliver, if an 8 Ohm cabinet is connected.
As soon as the power output exceeds 600 Watt, the power amp (not the Profiler) switches off for a short period of time. After about one second
Therefor if you connect a 4 Ohm cabinet, you should adjust your volume so that the power amp never reaches its 600 Watt limit. If it does, it wouldn‘t damage
the Profiler, but perhaps accidentally interrupt your solo play. Also for health reasons we strongly suggest to be very cautious with such volumes.
Keep in mind: A 4 Ohm cabinet is normally significantly louder than an 8 Ohm cabinet given all other parameters stay the same.
For the future we are planning a few firmware enhancements, which will increase the visibility of the power amp performance."
I am running a Voodoo Ground Control with an expression pedal (Boss volume pedal), the pedal works fine except I'm not getting the full range, toe registers about 102 instead of 127. I realise volume pedals aren't recommended but is it possible to calibrate this pedal in the Kemper? At the moment the Kemper isn't acknowledging a pedal is connected, I think it just sees it as midi information, not a pedal as such.
FWIW, my TC Electronic G Force worked perfectly with this setup, calibrated fine (even though the toe stopped at 102, it could see 102 as full), and even let me adjust the curve of the sweep in the software to correct the fact it was a volume pedal
Edit: sorry, just realised I probably posted this in the wrong section
I've recently bought a used power rack and been playing it happily for the last couple of months. Unfortunately when I've turned it on this evening I had a lot of noise coming through when I was playing (silent when not playing). Sounds like a blown speaker, distorted on clean sounds, just bad.
Thought it was bad headphones so checked through monitors, just as bad so checked Kemper's power amp to quad, no better. Thought it might be a lead or my wireless but after further investigation realised there is no noise through the front input, only through the rear alternate input.
I assume I've answered my own question but does it seem I have a faulty unit? I've found a few other similar threads with nothing conclusive. Is there any chance it may just be a firmware issue? My next step will be to contact support but just wondered if others have experienced the same fault and if so, how was it rectified?
Well... Devin Townsend returned to Fractal as he states that “something is missing” in the tones in Kemper. Steve Vai uses Fractal. And Satriani uses Fractal. Meshuggah uses Fractal, and so on...
I've noticed Vai in a rig rundown on youtube from 2012 with an Axe FX and a TC Electronic G Force in his rack, he's obviously using his Legacy for amp tones and assumedly the G Force for delay/reverb. What exactly is he using the axe fx for? Endorsement? Volume control?
Just noticed when I uploaded the pic, it seems the G Force is turned on and the Axe FX is off?
Sorry, obviously misunderstood the request you were making. Still got a lot to learn yet!
Hi, first post
+1 for delay mix control. I've only just bought my Kemper and haven't even plugged in an expression pedal yet, but I assumed I would be able to control any parameter with it, as I could with my tc g force (which I just sold). Honestly, delay mix was the only thing I used the pedal for. What's wrong with just allowing any parameter to be controlled by a pedal and let the artist decide whether it's useful or not?
