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 MID compatible keyboard/controller while using Duet with your iPad or iOS device.
Apogee is an award-winning industry leader in digital recording technology with over 25 years of experience. Preferred by recording pros around the world, Apogee products like Duet, Ensemble and Symphony I/O have been instrumental in creating countless GRAMMY® and OSCAR® winning recordings and have set the industry standard in professional recording for over two decades. Quartet is built solidly on this reputation.

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.
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.
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.
An Apogee technology first introduced in 1992 on Apogee’s AD-500 converter, Soft Limit can be heard on countless platinum selling records around the world. Once a technology exclusively reserved for Apogee’s most advanced audio converters, Soft Limit is included in Quartet and can be enabled in Apogee Maestro software.
This superior analog design prevents the digital clipping that causes distortion by instantaneously rounding off transient peaks before they hit the analog-to-digital converter. Soft Limit allows several more decibels of apparent level to be recorded while subtly providing an analog-like warmth to the sound.
