As a freelance location recordist, I have to work with many FOH “engineers” some good, but most get there gains hotter as the bands get flat out.
Asking them to change levels is not an option, due to their pressure :angry: (even worse if feeding folbacks etc) I am being polite………
So it would be great to have this feature, even if its just 10-20db like the L16. Then if possible, is it something that could be built in to the new remote soon? At the moment i have to use mic/line rack interfaces and manually turn down channels, or if time allows use xlr in line attenuation.
Sorry for moan as this is a great bit of kit, but intead of output attenuation, can it be put on the inputs ?

The uTrack24 can handle max +20dBu signal on each balanced input
The LR-16 can handle max +8.2dBu (pad off), +20dBu (pad on) signal on each unbalanced input
That should be enough almost every situation…

Hi!
You really get the clipping at the input or is it just your guesses?
The lack of adjustment of the input level is alarming to me. I have a negative experience with the Zoom R16 when recording a signal with analog mixers (direct out).. There was often clipped. I do not want to change one another, and ultimately get the same problem.
Excuse me for my English if I made a mistake.

Can someone give an answer?It will exceed the level when recording from direct out mixer? Whether someone is or is always good?

If you take a look for the technical specifications of the uTrack24 you can see the maximum input level can be +20dBu.
Your had negative experience with Zoom R16 probably because the inputs on this device can be overloaded easily in live situation because of the +4dBm input.
You can check the technical specifications of the mixer consoles what you want to use with the uTrack24, you can see the +20dBu should be enough in the live situation.

In “Zoom G16” such characteristics: Input Level -50dBm to +4dBm continuously variable.
Also it has an attenuator which regulates the level of the input signal. I thought that they and regulated by the value of -50 dBm to 4 dBm.
The distortions have occurred even if the position of the handle to the left.
As far as I understand, value dBm and dBu not be converted into each other.

Yes that’s right because the dBm depend on the load impedance. But if we take a typical situation (600 ohm) the dBm mach with the dBu value.
If you had different load impedance, you can calculate the the dBu value.

Hello Artemenko,
R16 input can adjustable from -50 dBm to 4 dBm is use for mic and consumer audio device
uTrack 24 is line in Pro grade device, can handle +20dBu input signal, so you can adjust everything from your mixer or mic pre
I think no need adjust again by uTrack 24

I can confirm the findings of Pretty Sound, that uTrack is capable of handling very hot signals nicely.
I too had the exact same findings on venues like Artmenko mentioned, though my uTracks did not go into clip in one situation, where the FOH definitely was!
