Who has Edifier mr4 speakers? There is a problem

[Dafter777]

Why is the sound quiet when you connect the audio interface to the TRS inputs, when the sound is loud on the RCA? Everything is fine with the cables, with the interface drivers, etc., everything is also fine. Everything was checked on other monitors and there is no such problem. Moreover, I checked on two different pairs of Edifier mr4 and the problem is also there

I believe the TRS, being balanced, are designed accept higher voltage than the RCA. So, while the RCA probably derive full volume at 2 volts, the TRS are likely to need 4V (or possibly 10V) to reach full volume

This is just awful my friend. The difference in volume is too big .

If you have a consumer device use the RCA inputs. If you have a professional device with balanced outputs, that should be able to drive the voltage to full range on the TRS jacks.

OP, which audio interface do you have?

I would expect a delta of anywhere from 6 to 12 dB between RCA and TRS inputs. 12 dB is about the difference between -10 dBV and +4 dBu, i.e. "official" consumer and pro line levels. Why is that a problem for you?

Если у вас потребительское устройство, используйте входы RCA. Если у вас профессиональное устройство с балансными выходами, оно должно быть способно выводить напряжение на полный диапазон на разъемах TRS.
Наилучшие пожелания и добро пожаловать в ASR!

Thank you very much bro!

I had different audio interfaces from behringer, and now I have behringer umc 404hd and the same problem. I thought maybe it was a defect from the behringer interfaces themselves, but I decided to check with the focusrite interface and still the same thing. And now in the same apartment in the same computer with the same audio interface, in short, all the same I had mackie crx-4bt there were no problems at all and even the small presonus eris e3.5 were louder

It is by design. Here is the MR4 owner's manual:

Thank you very much bro and does presonus eris 3.5 have the same parameters?

Thank you very much bro and does presonus eris 3.5 have the same parameters?

I don’t own and couldn’t for the life of me find the input sensitivity specs in the manual. Kinda irritating since this is a common feature, that trips people up from time to time…

 

[Dafter777]

Thank you very much bro. If the sound was louder in edifier mr4 via trs, 50 watts and bluetooth, there would be no competitors for it at all. Especially since it has DSP. Now I am considering PreSonus Eris E5 BT. I can't afford more expensive, and low classes of presonus with their AB classes are just terrible.

That being said, a typical Focusrite should go a lot louder absolutely speaking, generally +15.5 dBu maximum for a Scarlett (2nd gen: 2i2 up, 3rd/4th gen: Solo and up). Those little Behringers have very wimpy output levels of around 0 dBu maximum (i.e. around -14 dBu nominal). This is about what you expect when your analog stage runs on +5 V and the output is impedance-balanced only - a design that feels increasingly anachronistic in this day and age. There's actually onboard outputs, DAPs and dongle DACs out there with higher output levels than this, and I have gotten +9.5 dBu out of a cheaper Swissonic UA-2x2 as well. (Yes, you heard that right, they're potentially a downgrade from onboard audio.)

I would recommend the following cabling options:
Behringer UM2 / UMC22 / UMCxxxHD - TS to RCA unbalanced (headphone can go a bit louder if you insist)
Typical Focusrite Scarlett - TRS to TRS balanced (not instrument cable = TS to TS unbalanced)
Older / lesser Scarletts with RCA outputs only - RCA to RCA unbalanced

If you absolutely insist on getting unbalanced output out of a Scarlett with TRS jacks, either use the headphone out or employ two 1x TRS --> 2x RCA splitter cables (with just the left RCA being used for each), one for each of the rear output channels.

And now in the same apartment in the same computer with the same audio interface, in short, all the same I had mackie crx-4bt there were no problems at all and even the small presonus eris e3.5 were louder

So you already have the front volume cranked to maximum and it's still too quiet?

It can't be too hard to drive MR4s to their limits as people have written about them "falling apart" when pushed. So I reckon this must be well within the capabilities of typical 2 Vrms (+8.2 dBu) unbalanced outputs. The equivalent of those on the balanced side would be about +20.5 dBu. About the only inexpensive audio interface that can reach that is the Tascam UA-2x2HR (with +20 dBu max). So I won't be the least bit surprised if these wimpy little Behringers end up being a bit on the quiet side when using the TRS jacks, and would avoid this combo.

Bro, I don't have a weak Behringer, I have a Behringer UMC 404HD and it sounded loud and great on all monitors. I wrote about the expensive one above, but I'll repeat it again. I bought the Edifier MR4 for the first time. I liked it, I tried it on the small Behringers and hearing this low volume I decided that this was really a problem with the Behringer cards. Then my friend and I decided to try testing it on his Focusrite 2i2 sound card, the problem remained the same. Because of this, I decided to sell them. I sold them and then bought Mackie CRX-4BT for the same money. Excellent speakers, I know that they are multimedia. And everything was loud even through the small Behringer. Of course, you can't compare the MR4 and Mackie CRX-4BT because they have 4.5 inches and they are 50 watts instead of 42. They were excellent speakers, loud and clear sound. But I sold them because there was no low frequency control. I don't like virtual mixers and equalizers, and I don't want to buy an additional mixer because there's no more room on the table. I sold them because the bass simply drowned out all the songs when listening to music. I don't understand why they didn't add a low frequency control. I sold them and decided to "earn" some money and bought Presonus eris e3.5. Everything was great, again louder than edifier mr4, very clear sound, but then I noticed that at maximum volume they started to heat up a lot. I decided to exchange them in the store for other ones, the same problem. They heated up and the sound started to wheeze, and I like loud music. I know that you can't listen to it for a long time at maximum volume, but I didn't care anymore and I sold them and bought mr4 again, because I just can't afford something better because everything is expensive in my country. But presonus eris e3.5 heated up not only because they are small, but because they have class AB. And I thought about buying presonus eris e4.5 but I saw that they have the same class AB, but PreSonus Eris E5 is a pair, they have class D. I want to sell edifier mr4 again and buy them somehow.

The UMC404HD shares the same exact "Max. output level" spec with the UMC204HD and 202HD, namely +3 dBu. Here's how the 204HD does:

Behringer UMC204 HD Audio Interface Review

This is a review and detailed measurements of the Behringer UMC204HD Audio Interface (ADC/DAC/Mic Preamp). I reviewed it a long time ago. OK, it was just two years ago but in dog years, it is a long time. :) I had a different audio analyzer there which made it difficult to measure USB...

www.audiosciencereview.com

That's +3 dBu with a major following wind, normally you'd rather want to stay a dB or two short of that. For comparison, this is roughly in line with standard onboard audio (e.g. ALC892, ALC897).

The MR4 is not alone in having different sensitivity between balanced and unbalanced input, the Focals are also doing that. Were things still too quiet when using the RCA inputs and with MR4 volume all the way up?

It is possible that the MR4 designers were erring on the side of caution (possibly in the interest of keeping hiss down) where traditional monitor designers opted for plenty of gain reserve. There are cases like the Genelec 8010As which are so absurdly sensitive that folks owning them but unaware of the -10 dB input gain switch have been driven mad trying to eliminate every bit of muting pop noise in their DAC. (I was reminded of the folk tale involving a princess on a pea.) 106 dB SPL / 0 dBu @ 1 m is definitely too much for a 3" class monitor that can't do more than 96 dB SPL even short-term and is on a desk right in front of you (well, unless perhaps your interface of choice is the Rode AI-1, which for some reason has a whopping -5 dBu max output level). The domestic counterpart in the G series promptly drops 10 dB of sensitivity.
