These inputs feed to a pair of UA’s acclaimed Unison preamps. The two input channels are driven from a pair of XLR/jack hybrid sockets at the rear of the unit, with an instrument-level input on the front that overrides the rear channel-one input. Other than this detail, the two are identical.Īs you might expect with a compact interface of this sort, Twin X’s connectivity is quite limited. Here, we’re looking at the Quad variant, with four DSP cores. The latest addition to this range is the Apollo Twin X, a Thunderbolt-3 audio interface that squeezes all of the goodness UA is known for into a compact, portable and affordable desktop unit.Īpollo Twin X comes in two versions, Duo and Quad, and this reflects the number of DSP processing cores the unit contains. One of the biggest successes here has been the Apollo line of audio interfaces, whose combination of high-quality analogue circuitry, exceptional converter technology, and seamless DSP support has proved popular. Since being relaunched by James and Bill Jr, the sons of original founder Bill Putnam, in 1999, UA has focused most of its attention on the ever-growing market for products that enhance and improve the experience of computer-based sound recording. For more than 70 years (albeit with a 14-year hiatus between 1985 to 1999), the company has been responsible for groundbreaking innovations – the layout of modern mixing consoles, per-channel EQ, and the invention of send busses, to name but a few – alongside some hugely influential and still-desirable pieces of kit under the Urei and Teletronix brands.
