Poised to be the center of a home studio or mobile rig, the Universal Audio Apollo Twin X DUO Heritage Edition desktop 10x6 Thunderbolt 3 audio interface combines the sound, feel, and flow of analog studio recording with powerful DUO Core real-time UAD processing and a hearty bundle of 25 stellar UAD plug-ins.

Furnished with elite-class 24-bit / 192 kHz conversion akin to the popular Apollo X rackmount interfaces, the Apollo Twin X DUO gives musicians, producers, songwriters, and audio engineers the appreciable value of crystal-clear, high-resolution recording and mixing with low distortion (-117 dB) and immense dynamic range (127 dB).

The interface features two XLR-1/4" mic/line combo inputs and a 1/4" Hi-Z input, all with Unison integration for precise UAD emulations of classic analog preamps—impart vintage character of your choosing on microphone and instrument recordings while bypassing the unpredictable nature of old equipment.

Thanks to the switchable low-cut filter, pad, polarity inversion, 48V phantom power, and stereo linking on each analog input, you can efficiently optimize your incoming signals with straightforward buttons on the Apollo Twin X DUO's face. In addition to the two primary analog inputs, you can record up to eight more channels by connecting external preamps with ADAT or S/PDIF optical outputs to the TOSLINK optical input port on the Apollo Twin X DUO.

The built-in DUO Core processing allows you to monitor and record audio using classic analog emulations with near-zero latency and no burden on your computer's CPU. The plug-in bundle included with the Heritage Edition empowers you with 25 top-notch plug-ins ranging from vintage compressor and EQ collections to virtual guitar/bass amps and time-based processors. The included Console application provides control and recall of all interface and UAD plug-in settings including channel-strip presets, drag-and-drop functionality, and dynamically resizable windows.

Mac and Windows drivers ensure compatibility with all major DAWs including Pro Tools, Logic Pro, Cubase, Ableton Live, and more. The interface also integrates seamlessly with LUNA, Universal Audio's free Mac-based, single-window recording system with unlimited track counts and full Audio Units plug-in support.

The Apollo Twin X DUO offers a comprehensive monitor section with talkback functionality and dedicated front-panel controls for Alt Speakers, Dim, and Mono functions, as well as input and output metering capabilities. In addition to the dedicated stereo monitor feed and front-panel headphone output, two 1/4" line outputs are available for connection to a second set of monitors.

At any point, you can increase the power and capability of the Apollo Twin X DUO through integration of qualified Universal Audio hardware. Up to four Apollo interfaces and six total UAD-2 devices can be combined, allowing Thunderbolt users the ability to expand their I/O and DSP without abandoning the Apollo Twin X DUO. The Thunderbolt 3 port is backward-compatible with Thunderbolt 1 and 2 via a qualified adapter (available separately).

Related Questions and Answers

Q: 1. Can the Dante port be connected directly to the ethernet port of a PC, giving the PC access to the I/O?

A: No. The Dante port would be connected to a network switch that is also connected to the rest of your Dante devices and the USB port of the Shure ANIUSB-MATRIX would be connected to your computer.

Q: 2. Looking to use interface for phone interviews for radio broadcast and recording. I notice the XLR port is not standard...will this call for an adapter or different cable?

A: Hi. I have one of these units. May I ask, what you mean by not standard? What connector do you need? There is a 3 pin female XLR for audio into the unit and a 3 pin male XLR for audio out of the unit. They are below the keypad.

Q: 3. Can I use this device to: 1) send analog out to ATEM Mic In. 2)USB to comp-1 streaming soft. 3) Dante to comp-2 running zoom?

A: Yes, the analog output from the Shure ANIUSB-MATRIX USB Audio Network Interface can be connected to the mic input on the Blackmagic Design ATEM Switcher (set the input level on the ATEM for line level audio signal). The USB port from the ANIUSB-MATRIX can be connected to a computer for streaming audio, and the Dante port on the ANIUSB-MATRIX can be connected to a network switch to receive Dante audio, Power over Ethernet (PoE), and data from the control software, then the second computer can be connected to the network switch to send and receive audio for the Zoom meeting.

Q: 4. Is the headphone level independent of the main output level? That is, can I turn the "Monitor" control all the way down and still hear computer output on headphones if I turn the "Headphone" knob up?

A: The Monitor level and Headphone level are completely indipendent on the M-Audio M-Track.

Q: 5. Can it work with mac computers?

A: B&H # UNAPLSHE is the Universal Audio Apollo Solo Heritage Edition Desktop 2x4 Thunderbolt 3 Audio Interface that is compatible with Mac computers. B&H # UNAPLSUHE is the Universal Audio Apollo Solo USB Heritage Edition Desktop 2x4 USB Type-C Audio Interface for Windows.

Q: 6. Does the green signal/clip indicator LED glow from dim to bright as the signal level increases?

A: The LED will light up green when an input signal is recognized, and red if the signallevel is too high which may cause distortion or “clipping”. THe green level does not change from dim to bright.

Q: 7. Which cable is suitable to connect the device to my computer (Windows)?

A: The Universal Audio Apollo Twin X DUO Heritage Edition Desktop 10x6 Thunderbolt 3 Audio Interface can be connected to a Windows computer equipped with Thunderbolt 3 by using a Thunderbolt 3 cable like the Xcellon Thunderbolt 3 Cable - 1.6', 40 Gb/s (B&H # XCTB354005) or the Belkin Thunderbolt 3 USB Type-C Male Cable - 3' (B&H # BEUSBCC3BLK).

Q: 8. Could this function as a passive volume controller with 2 computer inputs via USB?

A: No, it can not be used as a passive volume knob for your computer.

Q: 9. What does Discrete ultra-linear preamps mean or do can this cancel out background noise pick up?

A: "Discrete" means that the preamps are made up of individually crafted components, and "linear" means that they amplify the signal at a fixed ratio. Neither of these terms entail any type of noise cancellation, which is not a normal function of microphone preamps. The Antelope Zen Tour Synergy Core Desktop Audio Interface is able to run real-time audio effects, some of which (filters and noise gate) can be used to mitigate background noise.

Q: 10. Does it accept an rj45 port and do you have to contact the I.T. department to allow the device on their network?

A: The Compak does not have an RJ-45 but if you have a network phone system, keep the base of phone connected into network via the RJ-45 jack. Replace the handset from said phone with the JK Audio Compak. The Compak will now act as a handset and will require no special access because the base station phone is already connected into the network.
