Using Hi-Fi Quad DAC with Impedance Adapter - LG V30 Questions & Answers

Hello guys
I have ordered impedance adapter from ebay the one @ChazzMatt have mentioned at many posts
Before using that i wanted to ask that will it work fine with custom mixer path tavils file that is included in anxiousv30 which provides dual speaker and volume boost
or will i have to restore the original mixer path tavil stock file
also can i use impedance adapter with aux cables in car or not ? i mean its safe or not ?

Really don't need High Impedance.
Also don't use the adapter with AUX cables. I'm honestly trying to figure out why anybody would do that in the first place.
Edit, when plugging in the AUX cables, the device will go into AUX mode.

The V30 in aux mode outputs the same level at max volume as my desktop Teac UD-301 DAC. You do not need more.
The whole boosting to high impedance mode is foolishness.

There are some headphones that need the 2 Vrms power of HIM vs the 1 Vrms of Aux mode. Planar magnetics in particular require a lot juice.
Playing at a lower volume level in HIM as opposed to at max volume in Normal or Aux mode may also slightly affect SnR, although we haven't been able to measure that objectively.
But I agree that going through hoops to force HIM with high sensitivity IEMs, only to turn volume way down is, well... :cyclops:
There is a persistent myth, going back to the V10, that HIM is needed to (fully) activate the ESS DAC, and that's what drives it.

I figured out why not to long ago.
LG is marketing high impedance as pure HiFi without mentioning the type of headgear that is giving high impedance. It's just marketing gimmick. Sure, full sized cans will give better sound while also going over 50 ohms. It would have been awesome if LG actually explained what they meant by having a better experience on high impedance.

Yes. I wasn't so much responding to that. I was merely pointing out that, while most of the HIM chasing is indeed unnecessary, there are a few cases where the extra power is needed, and where HIM is not triggered automatically.

Oh I agree man!
I also did a test on my 30 ohms IEM. Used an adapter to trigger high impedance. Talk about degrading audio quality.
All the people chasing high impedance is from misinformation. However as you always point out, some gear needs it though.

Ok so i currently own a pair of kz zs10 which have 32ohm impedance so i guess using adapter with them is going to be worth it or not?

I used it with high quality 35ohm earbuds, but then later after rooting, I used Anxious V30 module to get forced HIM. So, I no longer need to use impedance adapter to force HIM.
This quad DAC will try to give you the best sound, depending on what you have connected to it. So, that's why some say you don't need the impedance adapters.
But the impedance adapters are just to do what the Anxious V30 module does (force HIM or the equivalent) or whiskeyomega's audio mods. If people don't want to do that, they don't have to.

Noooooooo
The distortion is horrendous! Mostly I guess due to the BA. You don't want Anxious mod either. You can possibly kill the IEM's. I would HIGHLY recommend not using a mod. You don't need forced HIM with the KZ.

Obviously you have a choice of whatever color you want. This particular color is out of an aesthetic choice. The cable is for audio. I also noticed I set the volume down lower with the cable. You do get a bit of volume boost . If you find the volume not loud enough, it's because of stock cable.
This really does help the KZ and CCA sound better. I've tried every genre of sound. 3+ hours going between songs and cables and both IEM'S. So it's not placebo.
I can always host high rez files that I used. Just pm me if you want some good examples.

ROOT Your LG V30!
https://forum.xda-developers.com/lg-v30/how-to/root-v30-t3927154
The Root Sticky specifically talks about DTS. . Bottom of post #1.

I use my phone with 16Ω, 32Ω and 60Ω IEMs/Headphones and I don't care about impedance mode. Sound quality is the same whatever mode you're in, it just gives more power/volume that's it.
If you feel that your headphones are underpowered even at max volume, that's when you should think about these hacks. In most cases it's useless and not recommended.

V20 HiFi Quad DAC High Impedance Mod Help

On the V10 in order to have the DAC in permanent high impedance mode you simply modified the Mixer-Path.xml. I look for that file in the V20 system dump and couldn't find it. I was wondering if one or some of the great minds here at xda could search the system dump to locate the V20 Mixer-Path.xml or find a file that if modified would provide the same results when we get root. Thanks on advanced.

i don't seem to have an issue with high impedance headphones, i have a pair of Sony xba-h1 that have a ridiculous (for earbuds) 40 ohm impedance and they work wonderfuly. is there a reason you're trying to force it into high impedance mode?

Yes I want to use the full power of the amp on my low impedance rha ma750. I don't have to crank the volume as high and the sound is richer and crisper. [emoji2]

Would it be safe to use the high impedance mode for headphones which are not high impedance? My Bose headphones trigger the mode naturally but I wonder for my other headphones.

Until you find a software workaround, plug a splitter into the phone first. Then plug your device of choice into the other end of the splitter. This tricks the DAC into going into high-impedance mode.

That is aux mode not high impedance mode. You have normal (low) impedance, then aux mode (mid) impedance then high impedance ( max power). I'm shooting for maximum power. [emoji2]

Bump for this. Id love to see a high impedence mod. If someone could point me in the general direction to start looking on how to create some sort of mod, id love to try and see if i could mess around with it. Not sure how similar LG Nougat vs Samsung Marshmallow is...
There's a good amount of risk in doing that. You're forcing higher voltages normally reserved for drivers with higher resistance. Lower the driver resistance and your current draw on the opamps can hurt the device or fry your low impedance drivers if the gauge wire to the drivers isn't large enough. I don't really see the point in this mod. Any quality DAC is going to be able to drive low impedance hard enough. If your buds aren't loud enough, get better headphones. Just my. $0.02
I force mine into high impedance mode by using an inline sliding volume control, set to minimum when I plug in. It puts 470 ohms in series with my inefficient headphones. Slide it back to full volume after plugging in and I have 1.8V rms high impedance mode.
I too would like a software fix for this.

I'm pretty damn sure that if LG believed driving the amp at 100% power, even for low impedance headphones, were a good thing, they would have done it.
My SE846 IEMs use the low power mode. They sound fantastic. You are not doing yourself any benefit by trying to trick the amp into a high power mode, especially by using some piece of crap adapter. If anything, that is going to degrade quality.

Yes, but your SE846 are sensitive. Other headphones may not be. My Sine headphones need nearly x10 the voltage to reach the same volume. Portable headphone with this low sensitively and low impedance are rare, so LG did not cater for it. But they did allow for it with high impedance headphones, which are typically less sensitive.

The high impedance mode says it activates at 50 ohms and above. Unless your headphones are above 50 ohms, and somehow not activating it, you're wasting your time.

Different modes in the Quad Dac?

Hey guys, are there different modes in the Quad Dac? The v20 had Normal, External,and High Impedance depending on what you plugged in. I'm not getting any regardless what I plug in, auxiliary, or normal headphones. Any ideas?
Yes, there are different modes. Long press on the Hi-Fi Quad Dac icon in your quick settings. This will take you to all of the different modes.
I just got my audio files sorted and onto a card and into my phone. I'll take my Senn's into work tomorrow and have a listen. Also recorded some FLAC files tonight that I need to listen to. I'll be able to tell you tomorrow at some point. Up to this point, I've just been using my B&O's and some Apple ear buds that we just have laying around work. Neither of which trigger high impedance mode.
I think I misunderstood the OP's question, sorry about that.
I haven't noticed any changing of modes by plugging in different earbuds either.
That's what I'm saying. With the v20 you plug in axillary cable and it changed to external. You were even able to fool it with an extension. My v30 doesn't have that option, but I've seen it in couple video reviews.

OP- do you mind posting a screenshot of what you are talking about. I had V20 and remember seeing high impedance mode when I plugged in my aux cable. Sound was 10x better when it was in that mode. So V30 doesn't have different modes anymore, just on and off? Thanks
Yeah, I'm not seeing anywhere where it shows normal vs high impedance modes but it is definitely switching. Had my B&O's in which are normal on my V20 then switched them out for my Sennheisers. The volume jumped and the sound improved. So there's switching going on even though it doesn't say it like it did on the V20.

It might be due to software version. When I first had the phone (shipped from Korea) mine showed this as well. After the first of two updates so far, it no longers shows normal/high impedance mode.

I don't even know how to tell if the mode has changed. I plugged in an AUX cord and I think the only thing visually that changes is the settings screen says that the volume or something has been automatically adjusted if I use earbuds. No matter what, volume is limited to 75 it seems and is just shy of being loud enough for me while mowing and such

It seems not all v30s are having the same software. Maybe new software changes the mode automatically but doesn't show, why would it. It seems to switch depending on what you plug in, I can tell in the sound quality. It's just the peace of mind of it showing you to know it's actually working I guess.

I hear ya. With the V20 there was either normal HIFI DAC mode and Aux or high impedance mode and TBH the normal mode just wasn't loud enough. That's where I'm coming from, if we see the mode then we know that it's on its best,loudest setting.
Idc if it shows it, as long as it's working. I was worried it wasn't and I was missing something. After all this was one of the main reasons I got this phone, the audio.

200ohm adapter decreasing KZ ZS3 sound on V30?

I just got the DUNU 200 ohm impedance adapter but after I connect it to the mobile and then KZ ZS3 headphone sound is very small though it is showing now high impedance mode. Please help me out. even I tried another normal headphone, it's the same. Without the adapter, it was okay with normal mode. But it should trigger the high impedance mode with an adapter, right?

Seriously, that is not really a solution... High impedance headphones simply mean they need more power to drive them, hence the DAC provides more channels to support the gear. If you want more power to your lower impedance gear, LG should have provided a way to enable channels upon demand. They didn't, because it can be a pitfall (see below). Sometimes, 32 to 60 ohm gear really gain from the 25% increase of kicking in the second channel, as opposed to higher impedance which will just eat up that power and not give more oomph.
The DAC increase triggers around 75 ohm or while in Aux mode... My technique for non-root phones is to add an 3.5mm extension, plug in a high impedance adapter/headphones (75 ohm+), unplug adapter, plug in earphones in extension. There's the double-stack extensions (Plug in two in a row to trigger Aux mode), but I haven't had much success with this, worked only sporadically.
However, I strongly recommend simply rooting and flashing a DAC enabler mod. It's much easier to deal with... If most of your gear is under 75 ohm, that second channel will provide 25% more power. Only thing is: Very sensitive gear might not like more power. So be careful. I've known people with gear lower than 32 ohm blow their earpiece with a V30 at high impedance mode.
If you wanna test out triggering different DAC levels, download Hi-Fi status off the play store. It'll pop up a toast notification telling you in which mode you are as you trigger the modes.
**edit** if ever you want a 75 ohm adapter, I have one I'm not using... Depends where you live, I could send it your way.

Also, it's normal that your 200 ohm adapter decreases the sound quality of your gear if you plug in the adapter and then plug in your IEM's in it... Think of the impedance adapter as adding a bunch of ping pong balls in a corridor... When you walk through it, it'll be much longer to get across. Your 200 ohm impedance adapter is like adding basketballs in this corridor instead of ping pong balls. The adapter gobbles up most of the extra power given by the DAC, so your gear gets none of it.

I think I should root it. I have ordered Sennheiser HD570 with over 65-75 ohm impedance. Let me check it first. I also have hifi status app. hope it will help me. thanks.

I got Sennheiser hd570 with 64ohm. It shows high impedance...but still not much drive from dac...it has same output as normal mobile..why??sound is better as it is better headphone but loudness is not there.

ES9218P DAC All the time...

Hello, I was reading something that the V30 only uses the ES9218P DAC Chip when you insert a super high quality ear phone, can some one comment as to whether this is true? And if so, is there a mod or something to force it to use the chip at all times?

If you're on stock firmware the quad DAC is used all the time. However, how many of the quad (four) DAC channels are activated depends on the impedance of your headphones. Usually about 50 ohms for all four.
There are mods (requires root) to force High Impedance Mode (HIM) no matter what headset you're using. That's not always best if you're using low quality headset/earbuds.
I use a version of forced HIM -- using Anxious V30 mod, but she toned it down in later versions of the mod to only half the volume for earbuds with less than 50 ohms which didn't naturally activate "normal" HIM. She called it faux HIM or other names because some audiophiles argued with her terminology.
They'll probably argue with mine also -- but I'm explaining it so it's easily understood.

The quad dac is activated no matter what.

I will post a link that has a possible work around. I use it, but not sure that it is needed to enhance your low impedance phones. You can try it and see, I guess. It will be in the first post of the link as a "spoiler".
I also have downloaded an app that let's you know if it is in normal, external DAC (the work around), or HIM mode. The app is, "hi-fi status LG".

Use it or not. It may help or not. I do use the work around with my low impedance head phones.
The impedence modes only bump up the amplification to accommodate power hungry earphones.
There is no impact on sound quality. You should not worry about it, just plug in your erphones and enjoy.

Recommended 3.5mm adapter?

Hey folks. Just got an S20. Can we use any headphone adapter, or is there anything in particular we need to look for (DAC, etc).
Thanks!

I have "https://www.hidizs.net/products/dac-cable" and it’s really great.
I bought the iNassen 384KHz/32bit DAC adapter and I'm happy with it. https://www.amazon.co.uk/dp/B085PR63PK/ref=cm_sw_r_cp_apa_i_06xhFbPBF60H1
Whatever you choose, make sure it supports the S20. I took my chances via AliExpress and only the third one worked on my S20 Ultra (can't remember/retrieve the model).
I'm using the ibasso dc02 DAC. Just poweramp with simple eq on hd25s. Happy with quality. Given I used viper on my s7 which sounded better. Still waiting on proper viper support for my s20. Playing flac without issue.
Downside to this DAC is impedence is high thus low sound. But enough to block out noise with my hd25s

Works just fine with S20+ perhaps not the best for high impedance headphones (300 Ohm+), which require external amplifier.
