Quartet for iPad & Mac

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

Apogee Quartet is a professional USB audio interface designed to deliver the ultimate desktop recording experience to the iPad and Mac-based studio. Featuring 4 inputs and 8 outputs of Apogee’s industry-leading AD/DA conversion technology as well as 4 world-class mic preamps, Quartet bridges the gap between the 2-channel Apogee Duet and Apogee’s flagship interface, Symphony I/O.

Quartet for iPad and Mac features special circuitry designed to deliver professional performance for iPad use along with low latency USB 2.0 performance for Mac. Quartet's MIDI I/O connector lets you connect and power a Core MIDI compatible keyboard/controller while using Duet with your iPad or iOS device.

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 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.

 

Direct digital connection to iPad
Apogee ONE, Duet and Quartet for iPad and Mac feature special circuitry that makes a direct digital connection to iPad and iOS devices and is certified by Apple’s MFi (Made for iOS) program.

DC power charges iPad
In audio, adequate power is essential for excellent sound quality. With a direct digital connection and an external power source, ONE, Duet and Quartet are able to charge your iPad while you record so your work will not be interrupted.

Inputs & Outputs
All the I/O You Need

Analog Inputs
Quartet is equipped with 4 combination input connectors (XLR and 1/4”) for connecting microphones, guitars and keyboards or your favorite external mic preamps, compressors and EQs.

Digital Input
Quartet also includes 8 channels of digital input via 2 optical connections (ADAT/SMUX) for connecting an additional analog-to-digital converter such as Apogee’s Ensemble.

Analog Outputs
Quartet’s 6 balanced 1/4” TRS outputs offer an impressive range of possibilities. Listen and compare stereo mixes on up to three sets of speakers. Mix your audio or Final Cut video project in 5.1 surround. You can also take Quartet on the road and use all three stereo sets on stage, sending signal to the performer, monitor mixer and front-of-house. Quartet also features a studio-quality 1/4” headphone output allowing you to independently adjust your headphone level separate from the main outputs.

Word Clock
Quartet provides Word Clock OUT for synching an external A/D converter to Apogee’s superior clocking technology.

Starting with the Ultimate Speaker Demo, an ever-increasing number of the GearTunes audio  clips are being tracked using the Radial JCR Reamp. The Reamp was invented by my good friend and colleague John Cuniberti who engineered/co-produced many of Joe Satriani's most infamous recordings.

For GearTunes, reamping allows me to record a track where the guitar "hears" the amp in the room, but initially only the guitar or guitar and effects signal is recorded. This allows me to spend additional time perfecting amp tones and mic placement once I have the performance I'm looking for. One of the byproducts of this process is the creation of GearTunes DI Clips which enable you to play select guitars and effects through your amp by using your mobile device or computer as a reamp device.

For GearTunes DI Clips - and Gear Tune DI Clips ONLY (always found under the DI clips tab for gear that has one), you can play our guitar and effects through your amp. Simply use an unbalanced cable that terminates with an 1/8th inch jack on one end and a 1/4 inch jack on the other. Connect the 1/8th jack to the output of your mobile device or computer and the 1/4 inch jack into the front of your amp. Start off with your amp volume at zero and your mobile device (or computer) volume all the way up to ensure you hit the front end of the amp with enough signal, and then gradually increase the volume of the clean channel on your amp until you reach a level that is not capable of causing damage to your ears or equipment. GearTunes accepts no liability for the use, abuse or misuse of these clips, and playing them into your amp is done exclusively at your own risk.

I am tremendously excited about being able to share GearTunes DI Clips with you as you journey on your quest to find right gear for the music you play! Cheers ~ Doug:)
