Hi all

i have acquired a couple of subwoofer amp modules that have 4 user selectable settings via a push button selector on the amp panel. A bit of investigation on the Net seems to point the amp modules coming from a TFA-600BDP self powered bass unit- but I cannot find what the 4 settings actually are! - nothing in the manuals !  Help please!

cheers Stephen.

I dont need the monitors, just Mic inputs to record drums into the UMC-1820.  Does it require 2 cables.  (Not geting audio into studio 1)  I have the Master set properly as well as the ADA OUT to UMC IN and set to ADAT.

thanks

Hi everyone,

i just bought a factory new Deepmind 12  and I am super satisfied with the sound and everything works fine using headphones.

Yet, when plugging the audio out into either

1) My Guitar Amp / Bluetooth Speaker (PositiveGrid Spark, original 19V switching-power-supply) both
1-a) aux input
1-b) Guitar input

2) My trusty 90'es JVC Stereo System

3) an USB-Soundcard (on a laptop with Charger plugged in)

... and even more mains-powered devices of all sorts, with Euro and with Schuko style plugs (I live in Germany) into the wall, in different wall outlets in my flat, even one pulling the fuse for every other room/appliance. In any of the cases

I get a high-pitched, sometimes slightly pitch shifting, often periodically pulsing whine.

I used several audio cables and adapters without any success of fighting this noise.

The problem seems quite similar to https://community.musictribe.com/discussions/14773/217942/unwanted-noise-of-the-dm12#comments_body_217944

Yet there are some differences: The noise occurs even when the unit is turned off! When I unplug the power cable there is a mains humming instead of the noise. The noise seems to peak at 1,94 kHz. (see attached screenshot from a phone app and phone recording)

Depending on the used output jack, audio device and (and its input jack), the noise is either quite subtle or even louder than the instrument on half volume. In any case it is never fully gone.

It has no correlation with anything on the device (fan speed, wheel LEDs, VCA and its noise floor, ...) - as said it is even present when the Power swithch is on 0.

Now for the stranger part:

When taking the screenshot I noticed that the activity on my phone chipset (or display/display driver) altered the noise quite audible. The screenshot below shows this effect (of a previous screenshot) right in the middle of the spectrum flow.

So the whine seems to be picking up EM interference maybe because some kins of shielding? grounding? does not work propperly. I am no electronics person, so this might all be the wrong conclusions.... I have never experienced something like that with other audio equipment (e.g. Behringer Crave). I had also done a full calibration but the problem persists.

Another fun fact that puzzles me: The moment I pull the charger out of my Notebook (to which the USB soundcard is connected), the audio level coming from the deepmind drops drastically. What is going on there?

Does anyone have any idea? Am I doing something terribly wrong? Or is it a case straight for returning the device?

Hi Guy's, this is my first post here, I have a query that I hope you can help with.

We are a Ludite band using an Allen & Heath 14:4:2 Analogue Desk and we want to hookup the desk to a Behringer U-Phoria UMC404HD for recording purposes. Can we use the 'Matrix' Outputs from the desk as Inputs into the Audio Interface, or are there likely to be impedance matching issues? Also, if there are likely to be compatability problems, can you suggest a better solution?

The Matrix Out is TRS Impedance Balanced <75 ohm, -2dBu, +21dBu max.

I recently got a new iPad. Loaded TonePrint app. And the app does not recognize any of your user made TonePrints. 

what can I do to get this to recognize the TonePrints so I can edit them?

thanks in advance.

I'm new at this harmonizing pedal thing, is there a way to set an automatic low 3rd harmony in my Acoustic Play? I send my guitar signal so the pedal recognizes which key I'm in, so it needs to be automatic, without assigning a key to the preset. Is there a way?
