Assuming it is similar to the G103, it is easy.
Unplug from power before opening the device!
Take out the top two screws on front and back, then lift the top half off. There should be a pair of jumpers (likely red) that you move.
For details, take a look at the manual:
Isnāt hard just 4 hex screws and switching 2 jumpers and itās done 
HE6se V2 + G111. Anyone tried this combo yetā¦? Because thatās happening soon here :o Looks like the power at 50 ohms is perfect for it, ~1,925 mW! 
Iāll hear what youāll have to say about it before I think about importing a pair for the 650 $
I am interested too!
Can anyone compare - G111 vs A30 Pro?
NM, got another reply stating new ones have a switch now for 115 vs 230.
Hello Guys.
Iām venturing into the world of liquid music and for some time now I wanna create a desktop HEADPHONES system in order to listen to lossless musicā¦ I would like to gather opinions on how to move in the future regarding any purchases.
As for headphones, I have pretty clear ideas about what kind of sound Iām looking for. A high impedance open headset with neutrality features, tonal coerency and balanceā¦
I am seriously considering buying the Sennhesier HD600ā¦ If I decide to take HD 600, I also have to consider buying a good SS amp (no valves) that pairs well with this headsetā¦ A powerful amplifier of good construction, neutral and transparent tone could be a good solution for you?
At the moment on top of my preferences there are these two models:. LAKE PEOPLE G100. LAKE PEOPLE G111
If I have correctly interpreted the specifications, the Lake People G 111 should have no difficulty in piloting the HD600ā¦ The HD600 are high impedance headphones who needs a lot of ācurrentā. The Lake People has surplus power and voltage (it has a toroidal transformer powered) .
Output power 300 ohm-900 mw. Balanced/unbalanced outputs. Too bad for the lack of an āexternalā selector to adjust the gain.
Did someone try it coupled with an HD600?
Thanks To all
Itās a very nice combo, drives the 600 really well. Pretty neutral and clean while still being reasonably organic and convincing. Also wider stage then other options at the price point which does help out the 600
Iād also look into audio technica r70x on the can side of things as well along with the 600
What dac would you be pairing it with?
Hi Bro,thank you for your reply
Iāve not yet decided what DAC iāll purchese
Iāve a question about Lake People G100 and G111
Are they āpureā balanced Headphone Ampli (inner circuit) or has just XLR Input/output?
I believe they are single ended with only xlr input
@mon
Yeah I suspected it was so!
Anyway,Whatās the point of spending extra money on an amplifier with balanced inputs if itās like having a single ended DAC/AMP connection?
The lake people stuff is aimed more at the pro market, so having the ability to take in balanced signals is both convenient and helpful for longer runs, hotter level inputs, or if they are in an environment with a lot of interference, also helps tame ground loops at times.
Regardless of that, personally Iām in the camp that (for output) balanced vs SE doesnāt really matter, what matters more is the quality of the amp rather than if itās balanced or not. I do think balanced interconnects have more actual real world benefit, but for balanced headphone out I really donāt think itās inherently better than single ended output, but thatās a whole different thing to get into. I just feel these days that balanced has become a marketing gimmick to make people think an amp is better just because it has balanced, which is somewhat irritating lol
If I connect āBalancedā Input on the amp with āBalancedā Output of The DAC has to be via XLR cable yeah?
If I understand properly,This Type of connection Would be the BEST in order to not to hear ground loops
Is it right?
What about OUTPUT POWER at 300 ohm in SE for Lake People G100 or G109?
You can use SE rca or balanced 3 pin xlr, they sound somewhat similar (but this may not be true for your dac outputs), but if you have a dac that outputs balanced than might as well use that
Yes, thereās a lower chance of hearing ground loops with balanced vs single ended interconnects (although it could still occur)
I know for the 109p it was 1.9w into 100 ohms and like 600 mw into 600, so Iād guess around 1.3w into 300 ohm but thatās a more rough estimate. Unsure what the g100 puts out off the top of my head
Iāve a question:if I purchase a headphone amplifier with high voltage capability and with Output Power 400/500 mW on 3oo ohm in SE
I donāt need a DAC with balanced and unbalanced outputs.
The connection via RCA between DAC and Ampli would guarantee me the same performance?
Why a DAC with XLR/RCA Output?should be considered that there is price difference between DAC with Only unbalanced DAC and a DAC with XLR/RCA output
You just need a dac with one or the other, it doesnāt need to be balanced, but it can be if the dac ends up being that way
It just depends on the dac you go for. Generally for the price range something like the g111 sits in most of the dacs in a similar price range have balanced
Given the dacās single ended outputs arenāt bad it should be close enough to not worry about it (which they wonāt be if itās only single ended, but if you buy a balanced dac sometimes the single ended outs are bad because they are afterthoughts, but it depends on the dac), at least with the g111
Personally some of the pairings I like with the g111 is the schiit bifrost 2 (has xlr and rca, about similar sq between them with slight edge to the balanced output), the denafrips ares ii (xlr output is better and single ended output is lackluster), or like a soekris dac1421 or 1321 (which is only single ended, unless you step up to the 2541 or 1541 which have balanced and a better dac module/psu). So itās moreso that the dacs that I think pair with it happen to be balanced, but thereās many other dacs that pair well that are only single ended too (albeit at a higher price point)
Thanks Bro
Could you please Tell me a Good DAC Under 300 euro with Balanced/Unbalanced Outputs To pair with a Lake People G100 or G111?
I Canāt purchase Schiit Products because here in Italy are difficult to find.
The Only Option in That Range of price Is something like Topping modelsā¦Topping Doesnt appeal me.
I really good and flexible option for the money at that price point is the allo revolution dac imo. Sounds fantastic for the price, great flexibility in signature with some settings tweaking, good synergy with the g111. Can be upgraded down the line with nicer power supply if you are into that as well, although Iād start out with an allo nirvana smps if you can as itās a worthwhile upgrade, should be within your budget and able to be had near you. Personally my preference over a lot of the other dacs in this range like those from topping, smsl, etc
