Antelope Audio has announced the addition of four new vintage compressors to its library of FPGA (Field Programmable Gate Array) vintage hardware-based effects.

These effects enable owners of Antelope’s Thunderbolt and HDX audio interfaces to access unique hardware models of some of the most desirable vintage effects with real-time performance without relying on DSP (Digital Signal Processing) for native processing.

The FPGA effects can be free routed in Antelope Audio’s Routing Matrix view, which allows for fast and intuitive linking between audio interface inputs and outputs, including multiple-channel routing.


Antelope Audio’s all-new BA-6A follows in the footsteps of a 50s-vintage legendary limiting amplifier’s beautiful, effective, and simple design.

The hardware unit was originally created for television and radio broadcasting purposes, but became a firm favourite with recording engineers as it was so easy to use and sounded so satisfying. Today that not only holds up, but it is still sought after and used in some significant professional studio facilities globally.

Generating three-stage amplification with a moderate drive, hard knee compression, fast attack, and medium release, BA-6A brings a balanced, vintage sound to the present-day production table. Tame the most aggressive and peaking instruments or the wildest mixes without loosing sight or sound of any musical punch!


The FET-A78 aims to please anyone seeking some seriously punchy, classic-style compression.

Historically, its superlative sound supports innumerable pop and rock recordings. Remarkable when processing instruments individually, it is incredibly flexible; try treating drums, guitars, or vocals.

Versatility continues when also applied to tracked groups — such as backing vocals, overheads, and stacked synths — or even sound design duties… doesn’t disappoint! Use it in stereo mode or pour it over overly dynamic bass lines so that they finally behave themselves in the mix!


The SMT-100A is an 80s classic, and one of the easiest compressor effects to get used to working with.

Fortunately for all users, its ease of use does not mean sacrificing sound or effectiveness. Attracted to its fast attack times — perfect for vocals, drums, and punchy bass, the original unit has been the preferred choice amongst audio professionals at the top of their game for over 30 years.

Yet Antelope Audio has worked hard to preserve the special sound of this simplistic design and control set in the FPGA domain so users can focus on getting that sound — the smooth touch of vacuum tubes, in other words… without having to technically geek out to master this exceptional Eighties legend!


A contemporary fusion of finest American and British compression technologies, the Grove Hill LIVERPOOL makes for a familiar yet fresh sound.

While its origins can be traced back to the Sixties — a memorable musical era when iconic gear helped shape iconic artists, laying the foundations for unmistakably analogue-flavoured classic rock ’n’ roll records, it is as at home on lush, modern pop productions as it is on classic rock. Rotary knobs for controlling INPUT gain, THRESHOLD, ATTACK time, RECOVERY time, and OUTPUT ATTENUATOR (dB) gain guarantee gorgeous tube compression sounds that are rich, wide, and thick, thanks to their highly interactive nature.

Now users of Antelope Audio’s best- in-class audio interfaces can clearly bring body and soul to acoustic guitars; smooth out the midrange of guitar leads, synths, and vocals; or throw it on bass parts for fat, warm sounds. Pushed harder, Grove Hill LIVERPOOL responds in kind, adding a desirable edge without adversely affecting clarity.

BA-6A, FET-A78, and SMT-100A are available for Orion 32HD, Goliath HD, Orion Studio Rev. 2017, Orion Studio, and Orion Studio HD audio interfaces (with Goliath, Orion 32+, Zen Tour, and Zen Studio+ coming soon), while Grove Hill LIVERPOOL is already available for Antelope Audio’s HDX audio interfaces, with the rest coming soon.
