Hey so i am little new in the audio space and wanted to know if this solution is viable for my pc setup. i have a usb mic with a 3.5 mm headphone jack which i wanna use so i can hear when i talk and there fore i was thinking that i could get a cable so that i could connect the dac/amp to the 3.5 mm headphone jack (with the usb c plug on the back of the o2) and then plug my headphones into the o2 dac. the setup would look like this pc to microphone to dac/amp with (3.5 jack to micro usb) to a pair of hd 6xx? could this work or would i not be getting any use out of the dac then? this is the mic btw Svive Leo Studio kit

Hey, some general info to help you out (I can’t see the date you asked, so I apologize if I’m raising the dead here).
Short answer: it would work, but not the way you think.
DAC stands for Digital to Analog Converter - computer files and PC games are digital audio sources, but all speakers (even the little speaker drivers in headphones or earbuds) require analog power to create an electromagnet > magnetic push/pull > vibration movements that we hear as sound. So, all PC audio paths require a DAC somewhere.
In your case, your Svive microphone is connected to your PC by USB (which is a “digital” connection) and it has a DAC and ADC inside, as well as a little amplifier with not enough power for your Sennheiser HD 6xx (probably). The 3.5mm Jack is an analog-only connection, so you wouldn’t use a 3.5mm to MicroUSB cable… since the Svive already did the digital to analog conversion, you would connect the analog 3.5mm headphone monitoring port to the analog RCA jacks on the Objective2 amplifier (or 3.5mm jack, if the O2 amp has one, I forget). Therefore, the O2 would amp the analog signal from the Svive, and it probably would be powerful enough for the HD 6XX.
Ideally, though, you would connect the Microphone to your PC with USB, and then connect the SDAC to another USB port on your PC. That way, you would let each component do what they do best: the Microphone would just be a microphone, and the SDAC is the clearer/more realistic sounding DAC while the O2 amplifier is powerful enough for the HD 6XX.
Thanks for reading my TED talk. I Hope that explaining things provided clarity for you, and didn’t sound too tech-jargon-y.

EvshrugThanks alot dude i just posted it a few days ago so perfect timing.
but i a one issue is that i kinda want to utilize the sdac while it being there because its better than the one on my pc. but also its kinda issue if i do not connect the o2 to my microphone because then i wouldnt be able to get voicefeedback from my microphone.
i have 2 qustions:
- do you know if i can get both voice feedback from my svive leo microphone while utilizing both sdac and amp?

DrogemullerHi Drogemuller,
Sorry, I’m not in the best position to get into tech support for other companies products.
Just in general, you can only convert from digital to analog once, because after that step it’s already an analog signal, so you can’t use two DACs in line with eachother.
The SDAC’s input is fed by the Micro USB port. So, the journey the signal would take is Computer > USB (digital) > microUSB port> SDAC> internal analog signal path >O2 amp> 6.5mm or 3.5mm output > headphone cable> HD 6XX.
RCA inputs are analog, so they go straight to the amp (Svive’s internal DAC and Amp> 3.5mm monitor output (analog)>RCA input>O2 amp> headphone out> HD 6XX).
Since the SDAC is inside the O2 enclosure, feeding the digital audio in through the USB port should come out the headphone jack after being amplified (there may be a toggle switch to choose USB or RCA input… that’s all you need to do, pick which one you’re using). If you had separate DAC and amp components, the “chain” would look like computer > USB > DAC > RCA > Amp > analog cable > Headphones.
Here’s a video I made which may help you visualize it: https://youtu.be/AICNOmtYr4Q
You can only get the voice feedback from your mic if something is plugged into the 3.5mm (AUX) analog output on your mic. Your computer may be able to send the voice feedback/ Mic Monitoring / Sidetone to your default audio output device (the SDAC+O2 combo) if you use an app to turn on the feature. I don’t know if you want that for gaming purposes, but Discord may have that feature in their voice chat, and I do know the Final Cut Pro X, iMovie, and GarageBand apps on my Mac offer this feature when I’m making content.

Should I exchange the PC38X for better headphones?
I bought the PC38X headphones FOR GAMING and they are great, but I have NO use for a Microphone since I don't do competitive gaming and I was wondering if there were better headphone options at a similar price without a headphone, where (presumably) more of the cost was put into making it sound better. I also find that my PC38X don't get quite as loud as I would like and I was wondering if a cheap amp like the iFi Go link would draw a little more volume out of my phones. https://www.amazon.com/dp/B0BN6MM822?psc=1&ref=ppx_yo2ov_dt_b_product_details I went with the PC38X since it was considered the best bang for buck headphones. I care most about using spatial apps like DOlby Atmos and DTS Headphone:X. Suggestions are welcome.

Looking for a gaming/content audio setup
Hello! I'm looking for recommendations on audio setups. I'd be planning on using it mostly for gaming. Preferably I'd like a pair of large closed back headphones since I have a big head and jaw. I'd also like to hear myself through my mic with mic monitoring. As far as budget goes, I don't really have one. But under 600$ would be nice. I can go higher if needed. The audio setup would be connected to a high performance PC. Thank you in advance for any recommendations!

Trying to buy some gear off Drop for the first time. I was told I would receive an email with a welcome to drop $10 off promo. I never received that email. Drop was able to send me emails for my login token and email for Password update. But for some reason the $10 off coupon was never sent to me.

New here
Hello, I just joined, primarily for the audiophile products. Looking at purchasing the NHT C3 speakers for our new living room. Space is about 15 feet wide by 33 long and they will fire long ways. Space is just for general listening, music room with all equipment is downstairs, so hoping they will fill it with sound nicely. Cheers.
