Chapter 1: Introduction 5

Full Color interactive OLED Display
Pro Tools | Duet’s OLED display provides full color visual feedback and metering.
Multi-function Controller Knob
Pro Tools | Duet’s multi-function Controller Knob allows you to easily switch between Inputs and Outputs as well as adjust their
levels.
User Assignable Touchpads
Pro Tools | Duet's two assignable Touchpads can be assigned to control many of Pro Tools | Duet's settings and parameters. Use
them to setup advanced muting functions when recording yourself or to toggle between outputs.
¼-in Stereo Headphone Output
Pro Tools | Duet includes a ¼-in stereo headphone output that is separate and independently controlled from the stereo speaker line
outputs.
MIDI
Pro Tools | Duet provides a single USB MIDI connection for your CoreMIDI compatible keyboard, synth, or DJ controller. This
eliminates the need for an external MIDI interface and promotes an all-in-one music creation solution where Pro Tools | Duet and
Pro Tools IO Control manage all audio and MIDI.
Analog In and Out
This port is for connecting Pro Tools | Duet's breakout cable. The breakout cable includes two combination mic/instrument connectors
(XLR and ¼-in built into a single connector) and two balanced ¼-in connectors for speakers. The elegant single cable-to-junction
design allows for easy cable management and the locking connection to Pro Tools | Duet is robust and stylish.
DC Power
Pro Tools | Duet is easily powered by any available USB port on your Mac in most applications. However there may be scenarios
where connecting the external AC power adapter is preferred or required.
There are two factors contributing to increased power consumption:
• Output volume into low impedance headphones
• Phantom power for condenser mics.
This will appear on the OLED if the external power is necessary with Mac.
If you have Pro Tools | Duet set at a reasonable volume, you are not drawing a significant amount of power over the USB bus, and
will be able to connect any microphones that require phantom power. When you are using low impedance headphones and your
volume is very high, you are drawing more power over the USB bus and may need the AC adapter to use power-hungry condenser
mics.
USB
Pro Tools | Duet includes a single connection with two included cables to connect to the USB port on your Mac.
