Antelope Zen Quadro Synergy Core

Dual USB Audio Interface with Integrated DSP

Features

Conversion and Clocking

• Category-leading AD/DA conversion with up to 130 dB of headroom
• Recording, mixing, and playback up to 24-bit / 192 kHz
• Proprietary 64-bit AFC™ (Acoustically Focused Clocking) technology and jitter management algorithm for increased sound width, separation, and detail

Connectivity

• 4 discrete 6-transistor preamps with 75 dB of gain for extremely transparent recordings. All can function as mic/line inputs and two also as Hi-Z inputs, via XLR combo connectors, with 48V phantom power
• 2 monitor outputs and 2 line outputs on TRS
• 2 stereo headphone outputs with independent gain and mix control
• 2 independent USB-C (OTG) ports for simultaneous playback and recording
• ADAT input (up to 8 channels) and S/PDIF I/O (2 channels)
• DC-coupled inputs and outputs for controlling modular synthesizers via Control Voltage (CV)

Workflow-Optimized Features

• Direct monitoring with Synergy Core effects, processed in real-time with near-zero latency
• Simplified routing: audio source selection for each channel and each monitor mix, also available via the color display
• Simultaneous playback and recording with two computers or one computer and a mobile device
• Flexible loopback options for streaming
• Customizable presets with signal routing, level adjustments, mixer and effects settings
• Customizable monitor mixes with adjustable levels, panning, and reverb
• Class-compliant, no driver required on macOS and iOS
• Standalone operation: simply connect the unit to a smartphone charger and use it without a computer connection
• Remote control of software functions from a separate computer connected to the same network

Real-time Effects Processing

• Included library of 37 Synergy Core effects modeled on classic and rare analog gear
• Synergy Core, a proprietary FPGA + DSP platform for real-time effects processing, allows loading up to 48 effects simultaneously with near-zero latency
• Mic Modeling Engine for pairing with Edge microphones and real-time use of vintage microphone emulations

Included Real-time Processing Effects

• 22 guitar amps and cabinets, including Bluelux 1x12 and Tube Guitar Amp
• 5 compressors and limiters, including Stay-Levin, FET-A76, and VCA160
• 4 equalizers, including VEQ-1A and VMEQ-5
• 2 preamps, Gyraf Gyratec IX and BA-31
• 2 special processing effects, Expander and Noise Gate
• 1 reverb, Auraverb
• 1 guitar tuner, A-Tuner
