Analog passive DI box.

Jack came in and XLR ballanced "micro" level 600 ohm impedance.
output "through" that allows to interpose this case anywhere in the string sound, leaving scratches, post preamp and power amp same post.

A switch to reduce the output level when the branch between a power section and a speaker or dummy load.

a switch to enable / disable the "simulation of HP"

A groud lift to avoid ground loops between mixing desk or soundcard and the amp scratch.







I tested it in all its uses planned:

1/en simple DI output preampe in a "studio" it is doing its taff, silent imperceptible sound coloration.

I recommend live, it is passive and therefore requires the use of an active DI behind it if you want to send the entire signal until governed. I recall that the output level XLR mic level, not line level.

2 / In post amp:
Therefore real: Whichever I bought it! I play on my amp lamp, I interposed between the output of the head and the HP (watch it does not dummy load, it must still be connected even a speaker or a dummy load at the output "through"! !)



So the interest is that I have the exact sound of my amp + preamp lamp, I record the output HP and I use a software simulation of HP (Revalver imulse file with imported best quality)
I manage to get the exact sound of my rig, without the coloring induced taken microphones.

Also I just play my brand 100W lamps at night and save my house, replacing HP per charge (with proper impedance) fictional.
So I have the sound of my preamp, that of my head pushed to the sweet spot lamp (7/10 flight) without no sound coming out of my rig, I go through the pc and I have a hyper failbe volume returns, of very good quality thanks to the software to simulate the convolution HP

The only system which ensure that little role for the price of a medium effect pedal.


3 / simulation of HP:

So to just get a feel of a sound or play table without convolution mix the fact that we find the color of a standard HP 4x12 guitar kind / 2x12, the dynamics are really good and realistic vis a vis the comportament of a standard HP because it&#39;s not just a cut above, the circuit (analyzed in these last detail) includes inductor, capacitor and resistor that emulate well the bump very high mids, the small hollow mids and bass hump . cleavage of treble is fairly well placed.

However my regret is that it simulates an HP too neutral for my taste, the momentum is there, but the sound spectrum is too neutral for my taste it is more in the next fi sound, but not on the stack 4x12 of dream


For that I inadvisable this case if one is only a simulation of good quality in HP output preamp. In this register the home of the FANTA tubeampdoctor is much more effective and distinctive quality 4x12 cabinet.

However I like the fact that you connect between your head and live in HP, HP enable simulation of entering the bet and sound with the eventual small correction equalo when the quality of the stuff is unpretentious facade and that Eating place are sound source and uncontrollable feedback on a recovery by microwave.
Better not sound 100% identical to its quality rig but without feedback and phase cancellation, that the force at any cost transplanted by HP / mic so the quality of the gear and the room did not permetent optimally.




To summarize the +:
-The price.
-The sound quality of the circuit (although qu&#39;améliorable by replacing a same value coupling capacitors, but that&#39;s because I&#39;m a big geek DIY).
-The strength and quality of housing, the circuit and manufacturing.
-The ground lift saves me on one of my two recording stations (ground loop entered with two of my Cakewalk UA-25EX)
The easy-transplanted side / "feedback proof" live using DI output with my head on stage HP, HP integrated simulation and correction of frequency mixing.

Cons:
The simulation of HP-enough Typed guitar cabinet, was more like a scratch already mixed in a studio.
-The fact that it is passive. In the same asset with 9V battery will permit a level of output "line" on the XLR ballanced which would have made the perfect connection live. (Other active DI in this range do not allow a connection after the power amp section scratching unfortunately)


H & K does best and the worst. With this case we know little to show that all age groups in affordable, robust, reliable, good quality. And is one of the few to withstand a power connection post section.
I give it 8/10 because the correction of 2 points will deserve the negative 10. My rating takes into account the price / quality ratio that is a huge addition.
