There’s also a line of buttons along the unit, which allow you to toggle phantom power, and mute the monitors, for example, and generally provide more control over the preamps and outputs. This dial serves chiefly as a monitor-volume controller but can also be used for setting input gain, and alternate monitor and headphone volumes. The unit itself has a simple and intuitive set of buttons and meters on its top surface, along with a large data-entry dial. There’s also a headphone output on the front of the unit, and this has its own bus within the Twin X’s mixer, and can carry a different mix to the main and/or alternate outputs. As with any optical digital I/O, the specifics depend on the sample rate being used – for example, the S/PDIF input is only available if the interface is running at or below 96kHz, while the ADAT input provides eight inputs at up to 48kHz, four at 88.2kHz or 96kHz, and just two when running at 176.4kHz or 192kHz.įor outputs, Twin X has a main monitor output pair alongside a second pair of outputs that can be used for driving a second set of monitors, or as a couple of auxiliary output channels from your DAW. What makes these models so effective is that they modify the behaviour of the preamp’s analogue circuitry while also applying modelling algorithms in the digital domain, which results in some exceptionally accurate emulations of true-analogue mixing consoles and equipment.Īlongside the analogue inputs is a single optical digital-input connector that can operate in S/PDIF or ADAT modes. In basic use, these provide the clean high-quality signal essential for a good recording, but Unison’s real trick is its ability to load in classic channel strip, processor, and guitar and bass amplifier models. 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.
