Universal Audio Apollo x4
Universal Audio’s Apollo range of interfaces gains a new member. Jono Buchanan looks for signs of sibling rivalry
Universal Audio’s range of audio interfaces has always provided a twin approach to sound recording and processing. In addition to the high-end preamps and I/O you’d expect of a top-end audio interface, they’ve also provided access to UAD’s extensive effects collection. They use native processing to reduce load from your computer’s CPU and provide near-zero latency in the process. 18 months ago, the rackmount range of Apollo interfaces was updated with improved audio specifications and Thunderbolt 3 connectivity. At that time, the desktop Apollo Twin interface remained untouched by the upgrades afforded to its brothers, but it now gains many of the new specs offered by the rackmount Apollo units. More intriguingly, a new desktop module enters the Apollo family – the Apollo x4.
Like the other units in the revamped Apollo range, the x4 is a Thunderbolt 3-enabled interface and it’s a little less than twice the size of the Apollo Twin, offering a similar desktop, wedge-shaped design with a prominent rotary dial on its upper surface. The front edge provides twin guitar inputs on its left-hand side, whilst two, independent headphone outs feature on the right. Round the back, you’ll discover four Unisonenabled preamps from which the x4 takes its name. Unison is the proprietary emulation technology Universal Audio have developed to model the input behaviour of a range of classic preamps and channel strips, each of whose input levels and settings can be selected and adjusted from the rotary dial and top-panel buttons.
Output-wise, you’ll find six round the back. If your mind has leapt to the possibility of surround-sound configurations, you’re going to be disappointed, as the ports can’t be arranged this way. Instead, a Monitor stereo output pair is flanked by additional Outputs 1-2 and 3-4, which does mean that both effects loops or three pairs of monitors can be driven directly. Specs-wise, the Apollo x4 offers 127dB of dynamic range and -117dB THD+N, which is a significant improvement from the previous generation of Apollos. UA’s interfaces have long held an entirely

justified reputation for an open, warm recorded sound, befitting the company’s origins. That reputation is further enhanced here: the sound is sumptuous.
And, of course, it’s aided further by UAD effects provision. The x4 comes with a Quad processing chip onboard and bundles some classic effects, including the Teletronix LA-2A and 1176 compressors, 610-B Tube Preamp and Pultec EQs. Many more effects can be ordered, individually and in customised bundles from UAD’s store directly.
The x4 is an excellent addition to the Apollo range. If the Apollo rackmount modules offer more spec than you need, it should prove headturning and as a desktop front end to a larger system (up to four Apollo units and six UAD-2 devices in total can be daisy-chained), there’s an awful lot to like here.
