INSIDE THE BOX—Antelope Goliath HD

A 64-channel audio interface, Goliath HD is packed with the most comprehensive I/O around, including dual Pro Tools mini-HDX connectors, dual MADI optical I/O ports (to Dante Bridge) for up to 128 channels, plus a USB 3.0 Super-Speed, type B connector, as well as ADAT, S/PDIF, DB-25 connectors, and word-clock I/O over BNC. Along with 16 analog line inputs over DB-25, the Goliath HD also has 16 of Antelope’s high-quality Accusonic preamps, with XLR/TRS combo-jack mic/line inputs and individual level controls. The preamps also feature an extremely low THD+N of -112dB (where 0dB is the total signal), which maintain clarity as more tracks are layered. On the output side, there are 32 analog outs via DB-25 that feature a 129dB dynamic range, and mastering-grade monitor outputs with an amazing DNR of 132dB, thanks to yet another proprietary Antelope technology. Overall, the Goliath HD maintains ultra-low THD+N from analog I/O to converters to maintain the ultimate in clarity.Providing even more ways to get sound in and out of your DAW, along with sound-shaping capabilities, Goliath HD comes with eight Hi-Z instrument inputs, two transformer-balanced outputs for instrument re-amping, built-in front-panel talkback mic to commune with artists and other studio flora and fauna, two headphone outs and a pair of analog inserts for additional outboard processing. Goliath HD also has AES, ADAT, and S/PDIF connectivity.

Work in multiple DAWs simultaneously

With Pro Tools HDX mini connectors and USB 3.0, Pro Tools HD-equipped studios can accommodate guest producers with laptops and who can connect to Goliath HD and work on projects simultaneously. Additionally, Goliath HD guarantees quiet operation for the increasingly popular control room tracking, with musicians and engineer in the same space. Who knows, Goliath may actually make machine rooms a thing of the past. Additionally, thanks to Antelope’s proprietary HDX Delay Compensation, any analog or digital input will arrive in the Pro Tools | HD timeline with sample accuracy.

Antelope clocking and ESS converters for stellar sound

Key to Goliath HD’s sound quality it the combination of ESS Technologies latest generation converters with Antelope’s acclaimed proprietary clocking technologies. ESS Technologies converters are the gold standard for audiophile-quality conversion, while Antelope’s renowned clocking technologies include their oven-controlled crystal oscillator found in Antelope’s high-end crystal-based master clocks, and acoustically focused clocking (AFC) jitter management algorithm. The Goliath HD features OCX HD and Trinity-sounding audio clocking, plus for optimum detail and soundstage befitting master quality, Goliath HD can be synced to the extremely accurate Rubidium Atomic Clock 10MX. It’s BNC I/O enables it to be used for loop sync, or a master clock for your studio.

What is AFC?

AFC is an approach to digital clocking and jitter control. Since there is no standard specification for jitter or universal standard to measure sound quality, Antelope’s approach to clock design is based on the actual acoustic properties of sound. Precisely how AFC is achieved is, of course, Antelope’s secret to keep. However, the results are obvious to any recording or mastering engineer who’s put Antelope clocks in his signal chain, such as master mixer Michael Brauer, who relies on Antelope’s 10M and Trinity and insists his mastering engineer uses the same setup to preserve the spaciousness and sonic integrity of his mixes.

Antelope Oven-Controlled Crystal Oscillator

To achieve high-quality audio, a precision clock oscillator is essential. Oscillator accuracy is compromised when exposed to fluctuations in temperature caused by electronic producing heat. By housing the clock in a shielded container, or “oven,” as it is known to Antelope, a constant temperature is maintained, thus preventing fluctuations, while maintaining high-precision accuracy. The result is a significant, audible improvement in detail, dynamics, and stereo imaging.

Real-time tracking and processing via FPGA effects

 Rather than depend on third-party plug-ins and ever-changing compatibility issues, Goliath HD come loaded with Antelope’s full complement of hardware-based FPGA (Field Programmable Gate Array) effects. Because these effects are a function of the FPGA hardware and component modeling, they behave and sound like actual analog gear, providing the most authentic and realistic-sounding vintage EQs, compressors, and guitar amp and cabinet models on the market. You can track a vocalist with a zero-latency headphone mix with comfort effects, or record a guitar part with “live room” feel and tone, via amp and cabinet effects, plus you can select the mic that “hears” it, and change its position on a virtual speaker interface. Goliath HD takes recording a drum kit to another level its 16 mics preamps through FPGA in real-time.

You can also save presets for your go-to instrument and vocal signal chains, which can be recalled or shared with other Antelope-equipped studios.

About FPGA

To achieve its amazing low-latency real-time tracking through effects and multiple monitor mixes, Goliath HD uses the powerful Field-Programmable Gate Array (FPGA). “Field programmable” simply means user programmable. FPGAs can be reprogrammed to desired applications. Rather than a single path from input to output found in most other devices, Antelope’s FPGA has several parallel paths for ultra high performance. FPGAs easily push the 500MHz performance barrier with unprecedented logic density increases and a host of other features, such as embedded processors, DSP blocks, clocking, and high-speed serial. In the hands of a master programmer, such as Antelope’s Igor Levin, who coaxed more performance out of USB than anyone before him did; Antelope’s custom FPGA provides eight times the DSP processing speed than ASICs used in similar devices. This allows fast and easy simultaneous processing of multiple effects, better sound quality, and much lower latency.

Thanks to Antelope’s FPGA implementation, you can pile on as many effects per channel without maxing out the Goliath HD’s DSP—and it all happens before audio reaches your DAW, which saves resources for your processor-intensive plug-ins.
