Apollo Twin X DUO USB · Heritage Edition · Reference APLTWXDU-HE
A desktop interface reserved for Windows, with two Unison preamps and a DUO Core DSP: UAD compressors, equalizers and preamps can be heard while you record, and the Heritage edition brings five great classics.

The Apollo Twin X USB connects to a built-in USB 3 port on a PC running 64-bit Windows 10 or 11, ideally linked to an Intel controller. It does not work with a Mac or with Windows on an ARM processor, and USB 3 expansion cards are not tested by Universal Audio. Its USB-C socket expects a certified USB 3 SuperSpeed cable of 2 metres at most, to be provided, and its 12 V power supply with locking plug powers it: the USB port is not enough.
The two SHARC processors of the UAD-2 DUO Core DSP run the UAD plug-ins inside the interface. In UAD Console, you record through a preamp or compressor with a 1.1 ms round trip at 96 kHz, whatever buffer size your recording software uses. At the mixing stage, the same plug-ins open in that software in VST and AAX formats. For more power, a UAD-2 Satellite USB can be added, within the limit of two UAD-2 devices over USB.
Real-time processing stays in the Apollo, not in the PC's processor.A new interface, registered online on a Universal Audio account, receives the five titles of the Heritage Edition, four of which also exist as UAD Native versions for the computer. The Realtime Analog Classics bundle is added on top.
The two XLR and jack combo inputs on the back go through Unison preamps adjustable from +10 to +65 dB, with 48 V phantom power per input, a 20 dB pad, a 75 Hz low-cut, polarity inversion and stereo linking. On the front, the channel 1 Hi-Z input takes a guitar or bass, and the headphone output has its own volume. Monitor mode gives the built-in talkback mic, Dim, Alt, Mono and Mute, like a monitor controller.

The TOSLINK input on the back accepts an external preamp in ADAT, up to 8 channels at 44.1 or 48 kHz, 4 at 88.2 or 96 kHz and 2 at 176.4 or 192 kHz, or an S/PDIF pair up to 96 kHz. Disconnected from the PC, the interface keeps its latest settings and goes on serving as a small mixing console.

This version is not compatible with macOS: on a Mac, you need a Thunderbolt Apollo. The USB 3 cable is not in the box; choose a certified SuperSpeed model, Type-A or Type-C to Type-C, no longer than 2 metres.
