The Apogee Advantage
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
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
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
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.
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.

The highlight ring of the active touchpad is brighter so you can see at a glance which input or output is selected.
of Quartet’s assignable features
Three additional configurable touchpads (labeled 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 application.
Speaker set selection
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.

With plug and play connectivity to Apogee Quartet, you’ll be amazed by how simple it is to set up your studio.
Apogee. The first to make professional recording on iPad a reality.
Apogee pioneered studio-quality recording on iPad with JAM, the first digital guitar input and MiC the first professional digital microphone for iPad. JAM was featured in Apple’s iPad 2, GarageBand launch video. Now with ONE, Duet and Quartet, Apogee is the first to introduce professional multi-track recording interfaces to the world of iPad and iOS. These products complete this amazing platform by offering musicians, producers and engineers professional tools for music recording, production and listening.

Apogee Quartet Artists
“Apogee's Quartet is a great sounding interface, that enables a professional workflow in a home studio device. With excellent converters, a great stereo image, and an intuitive monitoring interface, I would recommend this interface to any producer or engineer.”
“The Quartet is so easy, it takes the stress out of recording and lets you get straight to the music. I initially tried to run my accordion through a series of pre-amp's and EQ's before channeling it through the Quartet, but at the end of the day, the best sound was achieved using the Apogee pre-amps on their own.”
“This is still a home studio, and it's got the vibe like that, but the Quartet makes it sound as good as it can possibly sound.”

Apogee Quartet Customer Reviews
“This interface is exceptional. The pres and converters are crystal clear, and the functionality, build quality, ease of use, and features are all outstanding. If you have a budget interface, you WILL notice a huge difference with this piece of gear! I had it up and running in minutes, and it has performed flawlessly ever since.”
Matt from USA
Worth Every Penny
“The sound quality is amazing and the functionality is better than any other interface I’ve ever used. It’s big enough to have a presence in the lab, but small enough sit on my Avalon and still allow it to breath. I bought it as a backup and mobile solution when my Avid Omni went in the shop for repair and it hands down holds its own in comparison. It’s also extremely stable. I have to reinstall Pro Tools HD to find my Omni and thunderbolt interface quite often, but I’ve only had to do one install with this box and its ran flawlessly ever since. I buy equipment all of the time and this is the first review I’ve ever been this compelled to write. I love my Avid Omni, but us creative enthusiasts tend to appreciate when a product has a solid price to quality ratio, and this box hit the nail on the head in that regard. The Quartet lived up to the hype and exceeded all of my expectations. It is truly a beast….”

“This is only the 3rd or 4th thing I have ever reviewed online because I generally think it is a waste of time. However when a product is this great it deserves recognition”

Apogee Quartet Press Reviews
“The preamps and converters in the Quartet don’t sound like a cheap circuit with the Apogee name; they have that Apogee sound. Rather than just being honest and transparent, it would be fairer to say that nothing is lost, but they do seem to add a little sparkle to the top end. When capturing the subtleties of the creaks and finger drags and the little details that make an acoustic performance feel real, the preamps of the Quartet and the One leave nothing to be desired. The same could be said about the way they record vocals. With all the breath and humanity that they preserve, the recorded performance is really true to itself…In general, the Quartet is a rock-solid music creation station. It’s serious, professional, looks fantastic and sounds even better. The features are just right, no frivolity. The iOS bonus just made it that much better.”
“While there are many manufacturers whose audio interfaces support iOS (RME, Focusrite, and others), Apogee are arguably more serious than most about their interfaces being used with iOS devices. The Quartet (like the company’s One and Duet interfaces) now comes with both 30-pin and Lightning cables, in addition to a regular USB cable for use with a Mac. And, best of all, that 30-pin or Lightning cable is also able to power and charge your iOS device. This is a really big deal since the majority of audio interfaces that can be connected to an iOS device don’t have such capability, meaning you only get one charge’s worth of music or audio work with the interface attached.”
