The ultimate desktop audio interface and control center for iPad and Mac

Apogee Quartet is the ultimate desktop audio interface and studio control center for professional recording on Mac and iPad. Made for the musician, producer and engineer that wants the ultimate sound quality and studio control in a compact desktop form factor, Quartet features legendary Apogee AD/DA conversion, 4 world-class microphone preamps, USB MIDI I/O, ESS Sabre32 DAC technology and monitor controls.

When you buy and register your Apogee Quartet, you have access to incredible prices on any Waves audio plugins you want. Registered Apogee Quartet customers will receive a discount code good for 25% off a single plugin or 35% off any Waves bundle plus an additional $100 voucher* that can be used towards their next Waves plugin purchase. Take advantage of Quartet's low latency USB connection and powerful native Mac processing to join the ranks of top engineers and producers who count on Waves and Apogee to deliver hit after hit.

With Quartet's 4 Combo inputs you can connect microphones, guitars, keyboards or line level devices such as external mic preamps or a mixing board. Expand your system with 8 additional inputs via Quartets optical (ADAT/SMUX) digital IN. Quartet also includes 8 analog outputs – 6 1/4" balanced outputs for connection to speakers or outboard equipment and a separate, independently controlled 1/4" stereo headphone output. You can control up to 3 pairs of speakers or set Quartet up for 5.1 surround monitoring.

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.

Soft Limit for protection from digital overs
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.

ESS Sabre32 DAC Technology
ESS Sabre32 32-bit Hyperstream DAC with Time Domain Jitter Eliminator offers unequalled dynamic range, ultra low distortion, and unmatched audio clarity free from input jitter.

ESS-Sabre-32
While ESS Sabre32 DAC has been widely recognized and employed in the audiophile community as the next step in converter technology, Apogee is one of the first pro audio manufacturers to employ this DAC in an interface designed for audio and video professionals. ESS Sabre32 DAC technology, as employed in Duet 2, Duet for iPad & Mac, Quartet and Symphony I/O, is one ingredient in the Apogee Engineering Difference. The benefits of the ESS Sabre32 DAC include:

32-bit DAC Architecture – Compared to older 24-bit technology, the Sabre32 DAC's 32-bit filter processing results in significantly lower noise and distortion, for a pure listening experience free from artifacts. 32-bit digital attenuation ensures that sonic purity is maintained at any listening level.

Time Domain Jitter Elimination removes clock inconsistencies from the incoming digital data, so the converted analog output preserves the clarity and soundstage detail of the original recording.
