Owner's Manual

Please note: models shipped after 2/25/20 have updated firmware that allows volume control with the front knob to the RCA jacks for more convenience. Power LED has been changed from white to purple. If you have a model shipped before this please contact us to get a firmware update.

The ARC Mk2 is an overhaul over the very successful first iteration of the ARC. Nothing is perfect the first time around so we've taken all of your feedback and suggestions and put it all into what we think is the ideal package. Microphone quality and clarity has been significantly improved over the Mk1, adding a more natural tone to your voice and increasing amplification to drive any headset microphone or modmic available. You'll no longer need to unplug headphones to switch between outputs on the ARC, now a convenient switch has been added on the front to making swapping back and forth easy. Analog input has been added so you can use your favorite phone, MP3 or analog source player into the ARC. Our favorite new feature is the deletion of the power supply. The ARC Mk2 can now be powered via USB, making it extremely portable and cutting down on wire mess in a desktop setup. (In vast majorities the ARC Mk2 will perform the same both with and without a power supply, but we've kept the DC port just in case extra power is needed). The same great high end performance is carried over from the MK1 giving you 1 watt of power to drive any headphone on the market regardless of impedance.

Great DAC/Amp

I like everything about the Mk2. The build quality is top notch, knobs, buttons etc feel solid. The design is sleek and aesthetically pleasing. If you&#039;re in the market for a DAC/Amp and have a budget in this range, I highly recommend it. Sure it may be pricier than other solutions, but I&#039;m happy to support local businesses, products made in the US and great customer support. A ten-year Warranty is unheard of. Not to mention, the sound is incredible. Brought my music and headphones to another level. Highly recommended.

Pricey, Quality and Simple

The ARC Mk2 drives my Sennheiser HD 6XXs and Antlion mod mic 5 well. It provides better noticeably better volume than a very nice motherboard and somewhat better sounding audio than a gaming amp dac combo like the GSX 1000 especially in music. The simpliciy and portability of the unit is convienient for laptop use and keeping you wires clean and minimal. The ARC is pricey for what is but is a great option if you are wiling to pay for quality amp that really help with wire management.

Works perfectly in Linux.

Works great in Linux, plenty of power to drive HE-500 headphones, mic quality is great, love it!

5 Stars

If i&#039;m being the honest the sound quality between the Mk1 and Mk2 is nearly indentical. What makes the Mk2 so much better for me was the improved Mic input and the ability to connect it through USB without needing a external power source. These simple improvements alone are very helpful given my setup. It&#039;s the perfect device for someone who games and just likes to listen to good sounding music. Also on a side note their Customer Service was top notch in reguards to my Mk1.

5 Stars

The ARC Mk2 is an excellent, easy to use and great addition to my PC gaming set-up. The ARK Mk2 delivers clear, comfortably and insightful sound as I game, listen to music or catch-up on the latest news. An audio investment that only grants buyer-glee and I highly recommend Mayflower&#039;s ARC Mk2.

Perfect for my UseCase

I come from a Xonar U7 and I hated it. The mic was low volume, useable on Windows but not on Linux. The Drivers feel not good and so on. The Ark MK 2 on the other hand has none of these issues. What can I say, its a good product, sound is good, it has a good Bass Boost mode. The input device change works. The IO is good. Only if you turn off the Device, it actually turns off, so it needs some time to reconnect. Which is not the fastest. The only thing, that could be better. Overall great Product!

5 Stars
So far so good

This is my first DAC, so I don&#039;t have much of a basis for comparison; but coming from my integrated Logitech USB Headset; the sound and mic quality with headphones + The Mayflower is far superior. Very happy!

Immediate, quick and dirty review which are often better than endless nights spent on the internet searching for answers that are irrelevant

I spent endless time debating between the current MacBook 2017 DAC which I have on my laptop, NuForce products, potentially Ifi, and products hundreds and hundreds more expensive than the above. I am currently using two interchangeable weapons: the Grado SR 225e and Sennheiser 600s. The latter I had for over a year, sitting in my desk drawer collecting dust because of issues with channel imbalance, or so I thought. Turns out this &#039;imbalance&#039; had nothing to do with a product defect but with the power required to get the most out of them. Enter ARC MK2. &quot;Oh but I don&#039;t;s for gaming...&quot; &quot;Oh...but...I don&#039;t want to be one of those audiophile snobs....&quot; &quot;Oh but my current MacBook is just so good as it is blah....blah...blah.&quot; Revist yourself, your life, your priorities, how seriously you take good sound, good quality, a good time. Zero channel imbalance. Headphones are alive. A good time. Sufficiently loud, better in every musical category, without the audiophile savant lingo. It looks cool. Impress the ladies and tell them to come over so you can show them your ARC. Then actually show them your arc. Good job Mayflower! it&#039;s a nasty little device!
