Best audio interface for 2.1 or 5.1 speaker setup

After deciding that I needed a subwoofer (Rythmik Audio L22) for my home mastering/editing system I decided to update my Apogee Duet to a Apogee Quartet to be able to easily integrate it and I was no wrong. I tried for two months splitting the outputs out of my Duet interface but got a lot of static noise form time to time and I knew it was due all the adapters and splitters. So decided to pull the trigger on the Quartet and man, this thing rocks. Now I'm using outputs 1/2 to send signal to my Dynaudio BM5 mkIII studio monitors and outputs 3/4 to the Rythmik Audio L22, then you have to select 5.1 speaker configuration and voila, the volume knob controls all the outputs simultaneously. This is not even explained on Apogee FAQ. So if you are looking for a great audio interface capable to run a 2.1 or 5.1 speaker system then don't look more and get the Apogee Quartet!!


The best purchase I ever made I can't complain.

A GameChanger

Coming from the Motu 828mk2 the Apogee One sounded amazing. However, mid day we received the Quartet and swapped out the One and was completely shocked at how detailed the low frequencies were. From top to bottom the Quartet is detailed, punchy, and super clean sounding. Operation is a pleasure with the touch screen, stereo to mono, dim, and much more. Worth every penny of the $1295. Apogee is quality!

Outstanding recordings interface

This Quartet is easy to set up, simple to use and provides professional level recording capability.


This interface is exceptional. The pres and converters are crystal clear, and the functionality, build quality, ease of use, and features are all outstanding. If you have a budget interface, you WILL notice a huge difference with this piece of gear! I had it up and running in minutes, and it has performed flawlessly ever since. The assignable touch controls are a real blessing for those of us who don't have more feature-packed consoles, and the Maestro 2 software is a wonderful tool for managing signal flow - very easy to use. The addition of ADAT connectivity will allow me to use this interface to expand my little home studio in the future as well. I've tracked acoustic, electric bass, and electric guitar with this box and all of the tracks FAR surpass anything I've accomplished before in terms of clarity and overall sonic quality. My monitors sound better as well! I have been truly impressed by the clarity I've achieved when tracking electric bass with these preamps, and my acoustic guitar tracks have never sounded this good. The quality of the pres and converters have helped take my mediocre mics and extend their usefulness, until I can afford higher quality pieces in that department. This was a great purchase, and I'd highly recommend it for anyone with a project or home studio that wants to achieve exceptional results. Thanks to my sales engineer, Andrew for yet another wonderful recommendation! I feel like I can always count on the people at Sweetwater for honest recommendations to get the most out of my limited budget for gear. Thanks!
