Smarting SPECTRA is a mobile hyperscanning EEG solution designed specifically for multi-participant studies. With full mobility, millisecond-level EEG precision, and microsecond synchronisation across devices, researchers can capture real-time brain activity from multiple participants simultaneously - without wires, bulky setups, or logistical headaches.
Smarting SPECTRA
Hyperscanning Solution
The Smarting SPECTRA Hyperscanning Solution delivers the ultimate multi-participant EEG experience. From lab studies to real-world social interactions, every component is designed for convenience and technical precision. Each participant wears a distinctively coloured amplifier for effortless identification, while the central PC manages triggers, alignment, and synchronised data streams, keeping your study organised and your results reliable.
Hyperscanning Software
Smarting SPECTRA Software allows seamless multi-device synchronisation from a single PC, giving researchers central control over multiple EEG devices. You can start and stop sessions, send triggers, and maintain a common clock across devices, while performing real-time, event-locked analyses across participants. The set-up is fully scalable, enabling you to add more amplifiers or participants without compromising timing precision. With simple software licensing, existing Smarting PRO or PRO X devices can easily be upgraded to support hyperscanning studies.
Multi-Participant EEG
Smarting SPECTRA is specifically built for social and group studies. Its portable design and ultra-lightweight amplifiers let participants move freely, while researchers maintain precise control over all data streams. Whether in classrooms, labs, theatres, or field environments, the system provides a seamless workflow with minimal setup.
Millisecond Resolution, Microsecond Synchronisation
EEG provides millisecond temporal resolution - but in multi-participant setups, precise alignment is critical. Smarting SPECTRA ensures microsecond-level synchronisation across all devices, enabling trustworthy hyperscanning, robust event-locked analyses, and precise multi-device data fusion.
Bring Your Setup Anywhere
Everything fits in a single backpack, making hyperscanning studies possible in classrooms, labs, theatres, or field sites. Fast setup, minimal power requirements, and synchronised multi-participant workflows ensure you get consistent results wherever your research takes you.
Upgrade Your Existing Devices
Already own a Smarting PRO or PRO X? Smarting SPECTRA lets you convert your devices into a hyperscanning-ready system with a simple software license - no hardware changes required. Get your team ready for multi-participant EEG studies in minutes.

Hyperscanning
Designed specifically for multi-participant research, Smarting SPECTRA supports 4+ participants simultaneously with precise cross-device synchronisation. Ideal for social neuroscience, classroom research, collaborative tasks, and real-world interaction studies, the system ensures all data streams remain tightly aligned throughout your experiment.
Multiple channels
Each participant benefits from 16 high-quality EEG channels, delivering robust neural signal acquisition while maintaining portability. The configuration balances mobility and signal fidelity, making it well-suited for both controlled lab environments and dynamic, real-world research settings.
Full Mobility
The entire hyperscanning setup fits into a single backpack. Lightweight, wearable amplifiers allow participants to move naturally without compromising data integrity, enabling studies beyond the traditional lab, from classrooms and theatres to field-based environments.
Easy Intergration
Existing Smarting PRO or PRO X devices can be upgraded via a simple SPECTRA software licence, with no hardware modifications required. This allows research teams to expand into hyperscanning efficiently, leveraging their current equipment while maintaining precise multi-device synchronisation.
Millisecond temporal resolution
Smarting SPECTRA preserves millisecond-level EEG temporal resolution while achieving microsecond-level synchronisation across all devices. This ensures accurate event-locked analyses, reliable cross-participant comparisons, and trustworthy multi-device data fusion.
