Hello,

Reading the product manual for the KT-2A leveling amplifier, found this written:

"The controls on the 2A-KT consist of a Pre-Emphasis trimmer which adjusts the compressor / sidechain interaction. When set fully clockwise, the sidechain responds to the full frequency bandwidth of the incoming audio. As the trimmer is turned counterclockwise, the compressor responds less to the signal's high frequency transients."

Shoudnt be the opposite for counterclockwise rotation? Meaning the compressor reacts more to high frequency acting like sort of a de-esser?

Why to react more on the lows and ignore highs?

I ask this because this is the functionality I know the older LA2A units have...

Many thanks for reply and clarification.

Hi,

I own a pair of KT-2As (and 76-KTs) and wanted to ask two questions.

1) Upon using stereo link and calibrating the two units with a 1khz test tone, using the Stereo Link trimmer at the back to get the same amount of gain reduction, I get different amounts of gain reduction between the two units when I move the Peak Reduction. The test tone is a mono signal sent to two outputs of my soundcard. No faders hhave been touched in my soundcard's mixer, the stereo output pair I am using on my soundcard, shows the same signal between the two outputs I am using for Left and Right that are the inputs to the KT-2As.

So I am using them unlinked which is fine, but the bottom unit in the photo, needs to have the Peak Reduction pot much more CW than then top unit to show the same amount of gain reduction. How do I go about calibrating the unit so that it behaves like the top one?

2) My units are running hot. I can put my hand on them, but they are very hot.

Do other KT-2A owners experience these two behaviiours I am?

Cheers!

I have a KT-2A which I use for recording and compression of bass guitar or electric guitar, and for singing ofcourse. The way I do this is:

- for the bass and guitar via a mic in front of the cabinet, and singing via a voice mic

- input that into a voice preamp, in this case a Tascam TA-1VP

- output that to the KT-2A

and in that case the KT-2A works fine, the meter responds as an indication that the signal is processed.

HOWEVER, what I also want is to add the KT-2A to the effects loop of my guitar amp, and this is what does not work:

- send the preamp signal of my guitar amp (Marshall JVM or Fender tube amp) to a DI box input

- connect the XLR output of the passive DI box to the microphone input of the TACAM TA-1VP

- output that to the KT-2A and connect the KT-2A output to the return of the effects loop of the guitar amp

In that case the meter of the KT-2A does not respond no matter how I set the peak reduction knob: the meter stays on zero.

I suspect the output of the SEND of the guitar amp is too different from the microphone output, even it I have a DI box in between. So how can I get the KT-2A to work in an effects loop of a guitar amp?

Hi everyone,

I recently purchased the 76-kt compressor and im absolutely loving it. I am aware of the rear vu meter adjustment pot as stated in the start up guide but there is also a small hidden screw directly underneath the vu meter that i have messed around with (which i regret doing) i dont know why i messed with it, i was just curious what it did. 

Im worried ive somehow messed up the calibration now as i presume this screw is factory set and shouldnt be altered. I can see that you can turn it clockwise and anticlockwise one turn and then it becomes stiff, you then screw further past that stiffness and it sort of resets to the loose, clockwise/anticlockwise setting as before.

Am i ruining the screw by turning it over and over to see what it does? is it some sort of spring that i am unwinding?

Id really appreciate any technical information to settle my mind on how this screw works and what you should do with, if i have perhaps ruined it by over turning it, or if i am just worrying too much?

Thanks ever so much in advance.

Hi KT team, I've followed a previous post from before Xmas and contacted suppliers re availability of a pair of 2As in a bundle I need.

Thomann replied with "sold out and not expecting any more". Please can you advise if 2A has been discontinued, I'm ready to order a pair of 2As, a pair of 76s and a dimension.

I purchased the 76-kt a few months ago. It's completely unusable due to the loud audio hiss. I was going to literally throw it away but then I thought of contacting you guys for help. I did create a ticket for technical support about a week ago but have yet to receive any reply whatsoever. The unit I have is completely useless. I mean just turning it on creates the most awful audio hiss. The higher the output, the worse the noise gets. I've tried everything from feeding it a hot input to avoid turning up the output level, to going through a gate to supress the noise but nothing seems to help at all because the hiss is very loud and can be heard behind the vocals or whatever I'm trying to compress. Any help?

Thanks in advance.
