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

Dual, high-resolution displays show all input and output details

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 & functions
QuickTouch pads for input and output selection
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
The ABCs
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.
Dial it all in
Quickly adjust input gain and output level with Quartet’s control knob
Apogee’s Duet started an audio interface revolution with its single controller knob design. Quartet continues this tradition. A single machined aluminum knob completes Quartet’s control center. With a tap to the touchpad you can select the desired input or output and precisely dial in your level.
