INSIDE THE BOX—Antelope Zen Tour

Without having to compromise I/O for DSP or vise versa, thanks to highly efficient and powerful custom-designed onboard processors, Antelope Zen Tour gives you everything you need to record multiple instruments, produce, and mix. It has four switchable mic/line inputs with phantom power, four Hi-Z inputs, eight analog outputs on a DB-25 connector, digital I/O on ADAT and S/PDIF and two independent headphone amps two separate pairs of monitor outs.

Zero-Latency tracking and flexible monitor mixing

Antelope Zen Tour lets you create and stream multiple complex mixes and process audio with zero latency. The Antelope Zen Tour is capable of streaming 32/32 channels of audio via Thunderbolt or 24 channels over USB 2.0 at resolutions of up to 24-bit/192kHz. The Zen Tour’s low-latency mixers provide all basic functions of a real mixer such as: Solo, Mute, Pan, Stereo Link, Volume Level fader control, and a Master Fader. It also features FX channels and Aux sends. Due to its ultra low latency, you can not only use Antelope’s AuraVerb in mixdown, but also for comfort effects while tracking.

To achieve its amazing channel count, stacks of onboard effects, and monitor mixes, Zen Tour uses the powerful Field-Programmable Gate Array (FPGA) from Antelope Audio’s top-selling pro studio devices. “Field programmable” simply means user programmable. FPGAs can be reprogrammed to desired applications. This feature distinguishes FPGAs from Application Specific Integrated Circuits (ASICs), which are custom-manufactured for specific design tasks. In essence, an ASIC has one path from input to output, whereas Levin designed Antelope’s FPGA to have several parallel paths for ultra high performance.

As it is, 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 Zen Tour’s DSP—and it all happens before audio reaches your DAW, which saves resources for your processor-intensive plug-ins. Zen Tour’s FPGA-powered Thunderbolt and custom USB make the Zen Tour lightning fast and compatible with any DAW.

High-resolution touch screen control

All of Zen Tour’s features are accessible via its high-resolution, top-panel touch screen. Zen Tour can be also managed via Antelope’s software control panel for OS X and Windows, with support for Android and iOS mobile apps for smartphones and tablets on the way. Antelope’s innovative networking control lets you access all Zen Tour features from multiple computers on the same network.

Classic guitar amps with hardware-based vintage FX

With Zen Tour, you don’t need to buy expensive DSP plugins. Zen Tour offers something better. The Zen Tour has 16 AFX Channel strips for sending and returning effects. Each FX channel strip allows you to stack up to eight effects (viewable in pairs).Antelope’s hardware-based FPGA effects include guitar amp and cab simulations, legendary EQ and compressor emulations, plus the extremely versatile proprietary AuraVerb reverb. Zen Tour’s FPGA effects offer unbeatable authenticity and realism. They not only sound truly analog, but also feel and behave like real hardware gear.

The guitar classics

Top30 models the bell-like sound of British Invasion spearheaded by The Beatles. This amp and cab produce a remarkably pure, clean and overdriven sound. Top30‘s controls include Volume, Bass, Treble and Top Cut. We’ve added a 2×12” speakers cab for this gem, because that’s exactly what it needs to do its magic.

Darkface is Antelope’s tribute to the most classic amp of the 60s. For vintage rock, jazz, country, or blues, this is the sound you’re looking for. The ability of this amp to preserve the natural tone of the guitar at high volumes is why it continues to be so popular to this day.

When you want to unleash sonic mayhem on an unsuspecting populace, Modern is the amp model of choice. Suitable for any metal sub genre, this all-tube guitar amp simulation is your best friend when you need super heavy distortion, and also when your leads and solos need some help to shine in the mix. This contemporary classic sounds best through a wall of speakers, which is why its default cabs are 4×12s.

Legends of EQ

Based on the EQ staple of recording studios for 60 years, Antelope’s VEQ–1A is not only breathing a new life into the classic Pultec and sounds as rich as the real thing. Like the original, you can boost and cut the same frequency, which creates a unique EQ curve that adds clarity by cutting surrounding frequencies. Whether it’s massive bass, gentle highs, richness, or air, the VEQ-1A surely does some analog-sounding magic.

Of course, the VEQ-1A is about lows and highs, which is why it’s combined with the VMEQ-5, the midrange’s best friend. Two peak bands and a dip are all you need to give your vocals, synth, guitar leads, or snare drum the analog punch they need. The VMEQ-5 can also clean up mud in the midrange like a boss.

To round out the Zen Tour’s EQ chores, Antelope gives you the parametric VEQ-55A, which is great for giving a bass guitar some edge, meat in your drums, and body in the guitars. The VEQ-55 will emphasize all tiny details your mix has been missing or remove the frequencies that stand in their way.

BAE 1073

Born in the 70s this channel module is based on the venerable 1073 that’s been used recordings from classics to modern. Antelope’s BAE 1073 can handle it all, from classical music to pop, hip-hop, and rock. Inspired by the hardware original the BAE 1073 can give your sound that very specific analog punch, which top producers have been cashing in on for decades.


AuraVerb is the first reverb created by Antelope Audio, featuring 24 custom presets designed by five-time Grammy-award winner, Brian Vibberts. The software-based AuraVerb leverages Zen Tour’s powerful 64-bit DSP chip and features a unique algorithm designed by Antelope’s team of mathematicians, including company founder Igor Levin.

AuraVerb features eight controls, including a “Color” parameter that creates everything between darkened textures to a brighter, sizzling presence, and “Richness”, which controls reverb density compared with the source audio. AuraVerb also includes pre-delay, an essential feature of reverb for creating clarity and space. AuraVerb is also capable of producing a wide range of authentic sonic landscapes.

Highlights of Antelope Audio’s AuraVerb include:

• New algorithmic reverb runs in real time on Antelope’s own DSP engine
• 24 custom presets created by Brian Vibberts for various instruments and styles
• ‘Color’ and ‘Richness’ parameters enable users to control different textures and densities
• Pre-delay can delay the onset of reverb by up to 150ms
• Long and smooth decays feature no digital artifacts
• Create your own savable presets and share with other AuraVerb users
• Signals can also be routed from DAW software as a Hardware Insert

Acoustically Focused Clocking (AFC)

AFC is not so much a proprietary circuit; rather it’s an approach to digital clocking and jitter control. As many audio designers have realized, what we can measure does not always correlate to what we hear. Furthermore, there is no standard specification for jitter or universal standard to measure sound quality—and no one understands this better than Antelope designer/founder Igor Levin, who is responsible for numerous digital audio innovations. Rather than simply adhering to rote mathematical formula, which cannot predict performance (two units showing the same specs can sound completely different to one another) Levin’s approach to clock design is based on the actual acoustic properties of sound. Precisely how AFC is achieved is, of course, Igor Levin’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

The oven-controlled oscillator is Antelope’s second proprietary clock technology. To achieve high-quality audio, the precision of the clock’s oscillator is of paramount importance. Oscillator accuracy is compromised when exposed to fluctuations in temperature caused by electronic components doing what they normally do: produce heat. By housing the clock in a shielded container, which Antelope calls an “oven,” a constant temperature is maintained, thus preventing the aforementioned fluctuations, while maintaining high-precision accuracy. The result is a significant, audible improvement in detail, dynamics, and stereo imaging.

Both of these technologies have made Antelope Audio clocks an industry leader in recording, mastering, and post-production facilities around the world. These innovations run through the entire Antelope line, from the Trinity their flagship master clock, up to and including the Zen Tour.

OUTSIDE THE BOX—Antelope Zen Tour

To host its considerable I/O, the Zen Tour takes advantage of front-, rear-, and side-panel real estate. The top panel of the Zen Tour features a high-resolution “capacitive touch” TFT display, buttons for gain, headphone select, talkback, and function select, which accesses various menus in combination with other buttons. A rotary control knob completes the top-panel’s complement of controls.

Antelope Zen Tour I/O:

• 4 line/instruments (Hi-Z) inputs
• 2 headphone outputs
• 2 reamp outputs
• 2 ADAT Inputs and Outputs
• 4 mic preamp/line inputs (4 Class-A mic preamps with phantom power over combo inputs)
• 2 monitor outputs
• Stereo S/PDIF I/O
• 8-channel D-Sub 25 line outputs
• USB 2.0 type-B connector
• Thunderbolt port
• DC power connector (for use with Antelope’s DC power supply only)

Antelope Zen Tour design philosophy:

Producing your own music has become the contemporary equivalent of writing poetry. Current technologies have made sound recording as easy as grabbing a pen and pouring your feelings on paper. However, unlike the solitude writing requires, music creation is usually a shared experience. A simple two or four-channel audio interface is no longer enough. A cool, creative jam with friends will require at least eight channels, packed in a portable interface that could easily fit in a backpack.

If recording and mixing in high quality whenever and wherever the muse strikes is your jam, the Antelope Zen Tour was built for you. For more information, call or chat with your Westlake Pro audio representative today.
