Apogee Quartet is a professional USB audio interface designed to deliver the ultimate desktop recording experience to the iPad and Mac-based studio. Featuring 4 inputs and 8 outputs of Apogee's industry-leading AD/DA conversion technology as well as 4 world-class mic preamps, Quartet bridges the gap between the 2-channel Apogee Duet and Apogee's flagship interface, Symphony I/O.
Quartet for iPad and Mac features special circuitry designed to deliver professional performance for iPad use along with low latency USB 2.0 performance for Mac. Quartet's MIDI I/O connector lets you connect and power a Core MIDI compatible keyboard/controller while using Duet with your iPad or iOS device. A difference you will hear
From the mic preamps to the AD/DA converters and the clocking, Quartet is best-in-class and cutting-edge Apogee technology. With components carefully selected in critical listening tests and a highly efficient circuit design, Quartet was built by Apogee engineers to make a difference you can hear. Pristine, next generation AD/DA converters
Quartet's AD/DA converters are designed to deliver the purest recordings and best listening experience possible. Quartet's efficient circuitry and state-of-the-art components provide a simplified signal path resulting in incredibly transparent recordings. Smooth, detailed world-class mic preamps
Much like the AD/DA converters, Quartet's mic preamps feature the latest components and offer seamless click-free transitions as the gain increases and decreases throughout the incredible range of 0-75dB. This unprecedented feature allows you to dial in the perfect level, either with the controller knob or from within software, while delivering ultra-low noise and smooth, crisp detail. Quartet's mic pres are suitable for all dynamic, condenser or ribbon microphones, allowing you to capture any sound without compromise.
