    Also, have just visited a BBC studio and any stage box inputs around the facility have 48V on as standard. As long as it's not a ribbon mic or an iPhone, it seems the approach is that it needs to be able to take it.

    On a similar note, (slightly off topic) i've witnessed phones and other devices being connected to desk inputs whilst on charge destroying the input preamp owing to a high "floating" potential from the feeding switch-mode power-supply (ever got that tingling feeling touching a device whilst holding an earthed device with another part of your body?) What i've learned from this is never connect an un-earthed device to your desk whilst its on charge- you take change especially with more sensitive/digital equipment.

    As mentioned by EdwardArnold , an unbalanced cable from a phone or device wired to phantom-powered input could damage that device, DI box will add some protection.

    If the phantom can't be disabled you should use the line level inputs on whatever the Kemper is plugged into, not the mic inputs. There should be no device that forces every input to use phantom power, otherwise it's only useful for things like condenser mics.

    Fair point, but in a live situation where the stage box is all XLR there is a higher risk. Back in the day, the BBC audio systems had phantom on as standard so all gear was treated the same. (quote from ex BBC engineer, Hugh Robjohns, of SOS magazine, if i recall correctly)


    The cautionary tale (certainly in commercial and "big-stage" productions) here is that often we are able to be responsible for the device at the other end and can not always guarantee what we are plugging into, especially if another engineer is taking care of cabling-up. and routing. The assumption that no phantom is present, or at least there is a risk it may be unavoidable must therefore be treat with caution if it could have an adverse affect on the gear connecting to it.


    i guess the XLR outputs of the Kemper are electronically balanced rather than employing isolating transformers and would therfore have some protection to block DC entering given this is a "pro" bit of gear.

    is it recommended (by kemper?) to use a transformer DI box as an isolation-device from phantom power if phantom cant be turned off?


    i was led to believe that it is not recommended to apply phantom power to the rack unit as it can lead to unwanted side-effects.

    thanks for the tips,

    How about buying some grill cloth and a nice Marshall logo and stick it to the "front" side of your flight case? ;)

    That's something i'm looking into also, though would want it removable as the case gets thrown in and out of vans

    There are Marshall dummy cabinets available: https://www.station-musicshop.…4398533%2FProducts%2F9463 (Sorry, german store)


    I personally would look for a broken cabinet on ebay and cut everything out that adds weight (speaker, etc.).

    a dummy cab would look great but is another bulky item to transport. Since selling my 4x12 cab i've enjoyed having the extra space and not having to carry it.

    Anyone use or have suggestions for a false speaker cab or, at least, the front panel of a speaker cab?

    Purely for cosmetic appeal to hide the less-than aesthetically pleasing item that the Kemper normally sits upon.

    the EQ button got de-activated some time ago so now the EQ and AMP button act as one.

    There was rumour that the EQ button was to be reimplemented for some other purpose but i can not comment further.


    Instead of having a "useless" button, why cant we please have back the ability to switch on/off the EQ block as it was before?

    Certainly, there's nothing to lose by re-using this redundant button.


    Surely, it's up to the user if they wish to switch in/out their EQ. I don't like the assumption approach by Kemper where they implement something they deem fit resulting in nothing other than loss of function with nothing gained.

    I'm sounding like a broken record I know, but please let output presets store everything and we'll deal with potential volume jumps. We are adults after all.

    its no different to loading some of the profiles in the rig-exchange where "certain users" save their profiles with a blow-your-hat-off output level, and this is is separate to the output setting. (Kemper have not addressed this or set some kind of standard in terms of level, nor would i expect it)

    At least saving ones "own levels" (the output section) you know what YOU have and you are therefore responsible for your parameter values.

    I dont have the mothership checking my power amp knob everytime i turn on my FRFR unit. (rant over)

    Many of us have a back-up or fly rig and, where the Kemper is our main tool, seek to get our "KPA tones" in that device.

    Sharing my attempts at recreating my "working" sounds on the HX stomp. (The HX presets are available- see link in video description)


    How do you think they compare?

    PS- this is not intended to be another "who's best" showdown. There's already plenty of those biased comparisons out there.

    what i think would be a useful solution/fix/alternative is that when a new tempo is set by tapping-in the new bpm value is (optionally?) displayed for a few seconds, just like when a “tempo sense” bpm is detected when holding down the tap button.

    It is then reassuring, whether auto-detecting or tap-entering, to see the new/actual bpm value


    i get the impresion that no one can truly rely on the flashing tap tempo button (on the remote or the kpa) as a reliable indicator of tempo at all bpm And it seems if this could be resolved it would have been done so ages ago.

    i can see the logic with not recalling volume levels too, but that's no different from turning on any piece of gear after someone else has used it and maybe (as their needs may be different to ours) left the volumes at a less than desireable level.


    Using mine in a variety of scenarioss, it would be handy to have the monitor/headphone/etc output levels instantly recalled for the situation required. I dont think Kemper will give us this (levels recall) as they feel too strongly about their side of the argument.


    the assignment of aux-in mono/stereo and its levels is a valid request, i believe.

    I'm aware that not all output settings are saved as part of the "output presets" collection, for certain/legit reasons.


    However, it would make sense that the "aux->mono" setting is stored as this is part of the output configuration especially given that the aux levels are saved.


    ...or i would be open to hear the counter-argument.

    i find, more so nowadays, when i turn up with a kpa there is a look of approval and relief on the engineer’s face as if to say, “ah that makes my job easier” and they recognise the quality and convenience of players using the kemper.

    It is clearly established as a unit of an approved and accepted standard. Other brand “all-in-one” floor units/amp-modellers (that may still offer quality sounds) can result in a raised eyebrow of dismissal but the kpa seems to be recognised as a device that is trusted.

    Can a mobile phone screen withstand the drop of a microphone or something heavier?

    I don't think so my friend ...

    Sounds like a sales pitch :* i like your idea.
    Agreed, a phone screen protector offers a limited level of protection. Depends how much “insurance” the user requires. Id say liquids are more of a hazard than solids. Those outdoor gigs in the UK can be wet. A practical risk assessment is needed. Should there be a risk of falling items perhaps a safety-hat would be wise also. Maybe thats what the village people had in mind^^
