Q4's FFR technology and large sound-field design deliver high-integrity, high-quality playback across bigger indoor and semi-outdoor spaces.
Three bespoke neuro-acoustic sound programs:
“I believe that this frequency technology of 7.8 is going to disrupt many industries related to sound. Even a session as short as eight minutes can have a great effect on your energy levels.”
Full Field Resonance technology delivers immersive coverage across larger venues.
High-integrity, high-quality playback rated for both indoor and semi-outdoor hospitality spaces.
Bluetooth AptX HD input for high-fidelity wireless streaming.
2.1, 4.1, or 8.2 configurations tuned to 7.8's proprietary acoustic geometry.
Q4 is designed for large sound-field immersive listening - ideal for indoor and semi-outdoor spaces that demand high-integrity, high-quality playback across every kind of hospitality venue. Configure it as 2.1, or scale it like Q3 according to the needs of the space, using 7.8's proprietary acoustic geometry.
FFR (Full Field Resonance) large sound-field system. Configurable as 2.1, 4.1, or 8.2 depending on venue size. Rated for indoor and semi-outdoor use. Bluetooth AptX HD connectivity. Every configuration is tuned for the same measurable brainwave entrainment as the rest of the 7.8 range. Minimal neural friction. Maximum reach.
Frequently Asked Questions
Q4 uses FFR (Full Field Resonance) technology built for larger sound-fields and semi-outdoor spaces, where Q3 is optimized for compact, shared indoor rooms. Both are configurable across 2.1, 4.1, and 8.2 layouts.
Q4 is rated for indoor and semi-outdoor use — ideal for covered terraces, verandas, and partially exposed hospitality spaces.
The human brain generates rhythmic electrical patterns known as brainwaves. Measured in Hertz (Hz), these frequencies reflect varying levels of neural activity and correspond to different states of consciousness, awareness, and relaxation. Neuroscientists generally categorize these patterns into five main frequency bands:
Delta (0.5–4 Hz): The slowest frequency band, most prominent during deep, non-REM sleep—a state naturally associated with physical rest and recovery.
Theta (4–8 Hz): Commonly observed during light sleep, deep relaxation, internal visualization, and creative reflection.
Alpha (8–12 Hz): Typically present during calm, relaxed, yet awake states, helping support a balance between external awareness and quiet mental focus.
Beta (12–30 Hz): Associated with active thinking, problem-solving, and conscious attention; high activity in this range is often linked to periods of heightened stress or focus.
Gamma (30–100 Hz): The fastest frequency band, associated with complex cognitive processing, memory retrieval, and information integration.
Auditory stimulation can interact with these natural patterns. Through a phenomenon known as brainwave entrainment, listening to structured audio rhythms—such as isochronic tones—may encourage the brain to align its electrical activity with the auditory stimulus, helping users foster environments suited for focus, relaxation, or mental clarity.
Three neuro-acoustic pillars: Meditation & Focus (Alpha 8–12Hz), Repair & Recovery (Theta 4–8Hz), and Relaxation & Sleep (Delta 0.5–4Hz) — each designed to support a specific biological state.
Large hospitality venues — resort pool decks, event lawns, expansive lobbies, and any space that needs immersive coverage beyond a single room.
