Like with the Avid Duet, Apogee have produced this interface to the same specifications as their standard Quartet, but it bears the Pro Tools branding and works on the Windows platform as well as Mac. What the Quartet offers is the ability to extend your recording capabilities when you most need it. Four analogue inputs on combination XLR/TRS connectors allow you to truly make the most of your intimate recording sessions. But, if that wasn’t enough, you have two optical inputs as well. This means you can use external preamps and run them via light-pipe into the Quartet for further inputs. Depending on the sample rate you are working on, you could run up to 12 simultaneous inputs with both ADAT connections giving you four inputs at 96 kHz. That makes for a pretty awesome input device for its size and price.

Offering more inputs means a bigger hardware device, obviously, so the Quartet has a little more space on the somewhat imposing case to offer additional control. You get a single rotary encoder/ button for volume control and data entry but additional functionality is also added with three configurable touchpads. You can easily select between speaker and headphone monitoring too and quickly jump from one input to another with the touchpads located below the LED monitoring section.
My only real gripe is the lack of a physical DIN MIDI connection on the device. Although, in this day and age, with most new MIDI devices are heading towards a USB interface, it is still nice to be able to easily connect legacy hardware up to your interface to keep it all running through one device. That said, it is a minor issue and anyone running serious outboard MIDI gear probably has a dedicated I/O device for this purpose anyway. So, that aside, this all comes together as a powerful recording system. With the Pro Tools iLok included so you are ready to go after installing the software, high quality home recording and production is now so much more of a reality.
