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

Quartets AD/DA converters are designed to deliver the purest recordings and best listening experience possible. Quartets 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, Quartets 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. Quartets mic pres are suitable for all dynamic, condenser or ribbon microphones, allowing you to capture any sound without compromise.
