The Ultimate Desktop Audio Interface and Studio Control for Mac, iOS and PC

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.

USB 2.0 High Speed, High Performance

Quartet features USB 2.0 High-speed connectivity to Mac or iOS device. USB 2.0 far exceeds the bandwidth Quartet requires for its 12 inputs and 8 outputs, delivering exceptional audio performance without compromise. Quartet is compatible with all of the latest Mac and Windows computers, including those with USB 3.0 and USB-C. Simply use the Apple USB-C to USB adapter to connect Quartet to to computers with USB-C ports, or use the available Apogee Official USB-C cable for Quartet.

Sound Quality. The Apogee Advantage

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.

ESS Sabre32 DAC Technology

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.

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.

Monitor Control

Quartet 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. The A, B, C selectors above the controller knob can be configured in Apogee’s Maestro software to switch between up to 3 pairs of speakers allowing you to use Quartet just like a standard monitor controller. Simply connect 1, 2 or 3 pairs of studio monitors and tap to select which pair you would like to listen to.

Apogee Maestro Software, Application For Low Latency Monitoring And Control Of Apogee Interfaces on Mac, PC, And iOS.

Access all control functions and settings with Maestro, Apogee’s comprehensive software control application. Maestro features a single window interface with quick access to all Apogee device settings. Select your input type, enable Soft Limit on mic and instrument inputs, and use the mixer for low latency monitoring. Maestro lets you easily configure your Apogee interface to fit your workflow. Maestro is included in the Quartet software installer for Mac/PC. Maestro for iOS devices is also available for free from the App store.

Logic Pro X Integration

If you are using an Apogee interface, you can adjust hardware input parameters directly from the Mixer view in Logic Pro X, including mic pre gain, input type selection, 48V phantom power and more. This simplified user experience helps you focus on a single session window when recording, and offers comprehensive visibility and control of input parameters. Quartet is also compatible with Logic Remote for iPhone and iPad which allows you to wirelessly control input type, adjust preamp gain, phantom power and more when Quartet is connected to a Mac running Logic Pro X.
