- The type of device port can be determined by the icon next to the port. Thunderbolt ports have a "lightning bolt" icon, while Mini DisplayPort ports have a "display" icon. The difference between these ports and icons is shown in the illustration below.
Quick Start: Installation, Registration, & Authorization
Quick Start Overview
- Follow the steps below to setup Apollo Twin. For a short video of the setup process, click here.
- Setup includes connecting the hardware, installing the software, and registration to authorize bundled UAD plug-ins.
- For more detailed explanations (and offline authorization procedures), see the UAD System Manual.
Connect to Computer and Power
Note: Before powering Apollo Twin, lower the volume of the monitor speakers and remove headphones from your ears.
- Connect a Thunderbolt cable (sold separately) between Apollo Twin and the Mac computer.
- Connect the included external power supply to an AC outlet (Apollo Twin cannot be bus powered).
- Connect the power supply to the 12VDC input on Apollo Twin's rear panel.
Important: Apollo Twin has a locking power supply connector to prevent accidental disconnection. When inserting, first align the two tab "wings" on the power cable's barrel connector to the notches on the power input. Then rotate the barrel clockwise to secure it to the Apollo Twin chassis.
- Apply power to Apollo Twin using the rear panel's power switch.
Connect to Input Sources and Monitor System(s)
One typical setup is illustrated below. Note that because the Hi-Z Instrument input on the front panel uses channel 1, the microphone is connected to channel 2 so both sources can be used at the same time.
For complete details about all of Apollo Twin's connectors and controls, see the Apollo Twin Hardware Manual.
To install the Apollo Twin software, follow these steps:

- For complete firmware update information, see the firmware support page.
Important: Do not interrupt system power during any firmware update routines.
Learn how to set gain levels for the mic, line, and instrument inputs, and output levels for the monitor speakers and headphones. Instructions are in the next section.
Setting Hardware Input & Output Levels
This section explains how to operate the panel controls so you can set input gain levels for the inputs (mic, line, and Hi-Z), and adjust volume levels for the outputs (monitors and headphones).
Refer to the top panel illustration below for the control names and numbers mentioned in this section. For detailed descriptions of all Apollo Twin controls, see the Apollo Twin Hardware Manual.
Important: Before proceeding, lower the volume of the monitor speakers and remove headphones from your ears.
Apollo Twin's top panel
Set Input Gains
- Select the input channel to be adjusted by pressing the PREAMP button (9) until the Channel Selection Indicator (3) displays the desired channel (CH1 or CH2).
- Select the input type (mic or line) by pressing the INPUT Select button (11) until the Input Type indicator (5) displays the desired input jack* (see note below).
- Adjust the channel's input gain by increasing the Level knob (1) until the input meter for the channel (4) approaches maximum, but does not reach the red clip LED when the input signal is present. If the level is too high to avoid clipping (when the red “C” LED illuminates), press the PAD button (11).
To set the input gain for the other input channel, repeat steps 1 – 3.
Adjust Output Volumes
- Select the output volume to be adjusted (monitor or headphones) by pressing the MONITOR button (10) until the Monitor Selected (6) or Headphone Selected (8) indicator is lit.
- Adjust the volume level by carefully increasing the Level knob (1) until the desired volume is reached (you may need to adjust the volume of the speakers).
To set the other output volume (monitor or headphones), repeat steps 1 – 2.
Mute (and Unmute) Monitor Outputs
- Select the Monitor outputs by pressing the MONITOR button (10) until the Monitor Selected (6) indicator is lit.
- Press the Level knob (1) to mute the monitor outputs. The Volume Level Indicator LEDs (2) are red when the monitors are muted and Monitor is selected (6).
- To toggle the monitor mute state, press the Level knob (1) whenever Monitor (6) is selected.
- *The Hi-Z input is automatically selected, overriding the channel 1 Mic and Line inputs, when a ¼” mono TS (tip-sleeve) plug is connected to the Hi-Z Instrument jack (12) on the front panel.
- To control both channels simultaneously when a stereo source is connected, press the LINK button (11) when an input is selected (9).
- Line outputs 3 & 4 are accessed and controlled via software only (Console or DAW).
Refer to the Apollo Software Manual to learn how to configure the audio interface settings, use the Console application and Realtime UAD Processing for live input monitoring, use the Console Recall plug-in in a DAW, and much more.
- Opening Console
To open the application, click its icon in the Mac OS X Dock.
- Explore the interface
For complete Console details, see the Apollo Software Manual.
General Usage Notes
- (Apollo Twin DUO only) Realtime UAD Processing with UAD plug-ins in Console uses DSP differently than when UAD plug-ins are used within a DAW. To maintain the lowest possible input latency, UAD plug-ins used on a single Console input are “chained” and must be processed within a single DSP chip. Therefore, it is possible to get a DSP/PGM/MEM limit exceeded message even though the UAD gauges may indicate there is plenty of DSP/PGM/MEM available.
- Session, plug-in, and I/O preset files saved within Console will not be saved if the "/" (forward slash), "\" (back slash), or "?" (question mark) characters are in the filename. Avoid these and other special characters when saving Console presets of any type.
Sample Rate Changes
- For optimum results when using Console without a DAW, perform sample rate changes within the Console application (instead of within Mac OS X's Audio MIDI Setup application).
- For optimum results when using a DAW, perform sample rate changes within the DAW itself (instead of the Console application or within Mac OS X's Audio MIDI Setup application).
- For optimum results when Apollo's current sample rate is different from the sample rate set within a DAW session, change Apollo's sample rate within Console to match the sample rate of the DAW session before loading the DAW session.
UAD Resource Usage
- Apollo Twin uses DSP and memory for its internal DSP mixer. Therefore, the UAD Meter & Control Panel application will show some DSP and memory usage even when UAD plug-ins are not in use.
- When logged into the computer under an account that does not have administrator privileges, saving UAD preset files via the UAD Toolbar will result in an "Unable to save preset file" dialog. If this occurs, either log in with an administrator account, or use the DAW's preset management tools.
What is the lowest hardware buffer setting I can use with Apollo Twin for stable operation?
The audio interface hardware I/O portion of Apollo Twin can run at any hardware buffer setting that is stable within the DAW itself. Results may vary as a result of how much the DAW session stresses the computer system. This can be influenced by:
- Session track count and sample rate
- How many processor-intensive native plug-ins (such as virtual instruments, convolution reverbs, etc.) are in the session
- Processor type, speed, and overall power of the computer
Of course, for the lowest possible latency when monitoring live inputs, we recommend using the included Console application to take advantage of Apollo Twin’s unique Realtime UAD Processing feature, where DAW I/O buffering does not apply at all.
- Important: System sleep is incompatible with UAD v8.0.1 (current release). See the known issues section for details.
- Disable sleep. Open the Energy Saver panel within System Preferences* and drag the “Computer Sleep” slider (if present) to “Never” (the far right position).
- To access System Preferences, press the Apple icon in the OS X Menu Bar (upper left of screen) then select the application from the drop menu.
Computer sleep is disabled in the Energy Saver panel within the System Preferences application
