Quartet is the centre of the modern studio and will help you take the performance and sound quality of your projects to the next level.
Total Creative Control
With its ergonomic, angular design and intuitive user interface, Quartet is inspiring, easy to use and in perfect harmony with your workspace. Dual full-colour screens for critical input and output details, QuickTouch pads for easy I/O selection, and a single controller knob to conduct it all, make Quartet the perfect studio control centre for your Mac.
Legendary Sound Quality
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.
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.
Much like the mic preamps, 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
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.
See Your I/O in Detail
Quartet features twice the display you came to love with Duet 2. Two high-resolution OLEDs deliver all the visual feedback critical for recording and monitoring. Without looking at your computer, Quartet lets you see metering, levels, grouping and phase, muting, phantom power and Soft Limit for all inputs and outputs.
Quickly Select I/O and Functions
Quartet makes it easy to access all important recording and monitoring functions. Simply tap a QuickTouch pad on Quartet's top panel to select an input or output and easily adjust your level with the controller knob. All input and output touchpads feature an LED highlight ring. The highlight ring of the active touchpad is brighter so you can see at a glance which input or output is selected.
Three additional configurable touchpads (labelled A, B, C) allow you to quickly access output functions such as 'Mute Outputs', 'Dim Outputs', 'Sum to Mono', 'Clear Meters' or 'Engage Speaker Set' selection. Each function can be assigned to a touchpad using a drop-down menu within Apogee's Maestro 2 application.
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.
Dial it all in
Apogee's Duet started an audio interface revolution with its single controller knob design. Quartet continues this tradition. A single machined aluminium knob completes Quartet's control centre. With a tap to the touchpad you can select the desired input or output and precisely dial in your level.
Maestro Control Software
Access Quartet's advanced settings with Maestro 2, Apogee's comprehensive software control application. Maestro 2 features a single window interface with quick access to all device and system settings. Select your input type, enable Soft Limit on mic and instrument inputs, use the mixer for low latency monitoring and assign speaker sets to touchpads. Maestro 2 lets you easily configure Quartet to fit your workflow.
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 analogue design prevents the digital clipping that causes distortion by instantaneously rounding off transient peaks before they hit the analogue-to-digital converter. Soft Limit allows several more decibels of apparent level to be recorded while subtly providing an analogue-like warmth to the sound.
