Lumin, Leedh’ing the way

[wklie]

After reading through all of the posts, I am still confused. I am currently running my T2 through a Classe Sigma passive preamp. If I try the Leedh, do I keep the Leedh processing volume at 100% and adjust my overall volume with the volume control with the circle around it?

You are probably mixing up the Max Volume % with the Leedh Processing Volume features. The Max Volume % is to decrease the actual volume to protect speakers - e.g. if the volume circle is 80, but the Max Volume % is 70, then your actual volume is 80 * 70% = 56. This feature works regardless of whether you use the Leedh Processing Volume or not.

Here's how to execute Scenario 3:

In your current listening environment with the preamp, please use a free sound meter app on smartphone to measure the volume level of your favorite track.

Stop the playback. Decrease the Lumin app volume circle to a very low level. Power off the amps. Direct connect the T2 to your power amp (i.e. bypass the preamp). Power on the amps. Start playback and turn up the Lumin app volume circle to match the measured sound level.

I only have a U1, connected to my DAC to pre-amp then to power amps to speakers.
Pls tell me if I am doing this incorrectly.
After removing my pre-amp, dac is connected to power amp, dac digital volume control is at 100.
In the U1 app:
Volume Control is at ON
Leedh Processing Volume is at ON
Max Volume % is at 100

Exit app, set top side circle volume control to 0
Turn my power amp on.
Start playing a track.
Tap on top right hand circle and slowly increase the volume level.
Am I using the Leedh feature ?

Yes. Before and after this please use a free sound meter app on smartphone to measure the volume level of your favorite track.

Thank you Peter,
Yes, I will do this soon and report back.

The Leedh processing upgrade with the U1 Mini totally improved my system sound.

Huge thanks for letting me actually hear the capability of my audio system for the first time.

Yes, and make sure the Leedh Processing Volume setting is On (default).

As for whether you should use the pre-amp volume or Leedh volume, please do an A/B comparison of SQ if possible and let us know.

Very strange that I cannot see the Leehing Volume control function in the app. Can you please take a look at my screenshot

iOS or Android?

Please make sure you're on Firmware 13, and update Lumin app to latest version.

If you're already using the latest app, please kill the app and relaunch it.

Thanks Peter, I have realized that I haven’t update my Lumin app to the latest version. Now I can see it! Great thanks

In order to trigger the Leehing, I need to leave Volume to On and the Leehing Volume to 100? I am a bit confuse that when I control the volume using the app, shall I adjust the volume under Leehing Volume or the regular volume button in the app? Thanks

Use the volume in the circle.

You are probably mixing up the Max Volume % with the Leedh Processing Volume features. The Max Volume % is to decrease the actual volume to protect speakers - e.g. if the volume circle is 80, but the Max Volume % is 70, then your actual volume is 80 * 70% = 56.

I hope this description can be useful, it's my point of view about how should be explained in APP.

---> The "circle volume" on the main screen is: MASTER VOLUME (it controls the output of any sound EQ the device is running)
---> The "(%) Max volume" inside option mode is the GAIN of the respective sound EQ: the LUMIN one or the LEEDH if this feature is switched to ON
-- > The switch "Volume control" inside option mode turns ON or OFF any sound EQ, and the "Master Volume" (if its set to OFF) on the main screen becomes unusable (position 100, Max, like APP rightly warns)

Hello everyone, after several tests and listening to my system, I share my thoughts about Firmware V13. First of all, I would like to tell you that in my system I had a lot of bass (amplifier controls all in 0), installing the V13 Firmware and activating the Ledh volume and the Lumin app, I managed to improve the sound in general. All the changes I notice
1. Quieter background
2. Treble much smoother
3. The precent bass but without making a ball of bass.
4. The Lumin X1 sounded exceedingly good before the V13 but now it sounds exceptional, I enjoy the music more.

My thanks to Peter and the entire Lumin team for this great GIFT. Cordial greetings.

I think launching this at the same time as Leedh may have lead to some confusion.

Max Volume is there simply to restrict/limit the volume to prevent accidentally overpowering your speakers or ears. It is simply a convenience feature. It has no effect on volume itself.

It is aimed at LUMIN Amp owners, customers who connect their LUMIN directly to a power amplifier, and customers who set a pre-amp at unity gain.
In these scenarios, it was previously possible to accidentally turn volume up too high and damage speakers/ears.
So we've added this Max volume limit to prevent that.

Users who adjust the volume via pre-amp, are still recommended to run volume at 100% (the only way to do that is if Max volume is also set at 100%).

We are considering renaming this setting Max Volume Limit and perhaps adding a Max Volume Limit on/off setting. This is still in discussion.

Hope that clarifies.
Apologies if you already knew all that!

Note: We could have just made Max Volume just make the volume circle never go above a certain number. This would have perhaps been clearer, but we wanted to retain the granularity of 1-100 adjustment whatever your Max Volume setting. (for example, if someone found their max to be 19%, that would have limited their adjustment to only 20 positions, which isn't fine enough).

Agree with your appreciation about the SQ of the new update also with my T2
(wrote similar concepts in another thread)
In my system I miss a bit the deep bass in some albums...
But the sound and integration of the whole spectrum is great

Could you indicate the volume level of Leedh and the T2 app please.

 

[Audiofan57]

Andik777: I wanted to make sure I understood your comment item # 3. Are you saying that although treble is now smoother, you are hearing at times less bass Impact as compared to before the firmware upgrade?

 

[Soniq]

Well, first of all thank the entire Lumin team for the new firmware version that incorporates the leedh processor.
In my particular case, a Lumin T2, the change was very noticeable.
I really used the volume of the app, since I have an integrated valve amplifier without remote control, it is an EICO ST 40 from the 60s, which I opened from its original box back in the 90s, and I still keep it with little use, since I started using it about 8 years ago. (I do not permanently use this system, since there are other systems sharing the space).
The speakers connected to this amplifier are original Tannoy Cheviots from the late 1970s, in their second version. (with original Tannoy recone made approximately 5 years ago and crossover upgrade).
The change is really very noticeable.
- More controlled bass with greater impact.
- Greater separation of instruments
- Higher level of detail in general
- Smoother and more natural treble
- Higher level of silence.
It brought a lot of musicality to this particular system, now I will begin to evaluate it with my other systems, although in a brief listening with Vincent SV-700 + Tannoy 615 MKII I also share those concepts, with the obvious differences in timbre and characteristics of each of these systems.
Music is really much more enjoyable.
Despite having fairly modest systems next to many (or most) of the users of this forum, I hope to be making a worthwhile contribution for those who may need it.
Best regards.

Because I have a preamp (Luxman C900) I don’t use the Leedh feature
and the volume is fixed at maximum.
So the change is in the new firmware and not only when using the Leedh control

PS: live in Israel but I was born in Buenos Aires

I also use a Preamp and I´m just using the new firmware and Leedh volume with very good results.

Probá bajándola y a ver que notas en tu Sistema, seguramente sientas mejoras.

Saludos-Regards;

No, when I play non MQA music or listen to TuneIn radio the volume control also does not function.

So is it correct the volume control does not function on U1 Mini when connected to an USB Dac but not playing MQA music?
