Monitoring Reference for Listening, Arrangement, and Pre-Production
VIORA CORE is designed as a reference point for listening, transcription, arrangement, and pre-production.
Rather than enhancing or flattering the sound, its purpose is to provide a stable, repeatable, and trustworthy sonic baseline, allowing musical decisions to be made with confidence.
For musicians and creators developing their monitoring skills, or professionals who require a reliable in-ear reference for long working sessions, VIORA CORE serves as a solid entry into professional monitoring.
Natural, Balanced Tuning — Free from Sonic Colouration
The tuning philosophy behind VIORA CORE is simple: stay out of your way. No boosted lows, no sweetened vocals, no exaggerated detail. Just the natural proportion, structure, and energy of the music, allowing you to maintain a clear sonic memory when switching between systems.
LiveSound — A Core Acoustic Element of VIORA
At the heart of VIORA CORE lies the ACS LiveSound acoustic structure, an integral part of its overall design.
LiveSound is not intended for stage interaction in this configuration. Instead, it is engineered to control air pressure within the ear canal, effectively reducing TVIG (Trapped Volume Insertion Gain) and minimising unnecessary stress on the eardrum during extended listening sessions.
By relieving internal pressure, LiveSound contributes to a more open, spacious soundstage without sacrificing clarity, helping reduce listening fatigue and supporting sustained, focused work.
Designed for Long Sessions
Both the sound tuning and physical design of VIORA CORE are optimised for extended use.
The presentation remains clear and relaxed over time, while the universal shell design—derived from over 20 years of ACS custom-fit experience—offers a stable fit across a wide range of ear shapes, maintaining consistent sound delivery throughout long sessions.
The Starting Point of a Professional Monitoring System
VIORA CORE forms the foundation of the VIORA PRO-MUSIC system.
It establishes a reliable baseline for monitoring, allowing users to transition to higher-dynamic, system-level, or stage-oriented solutions, such as the PRO-MUSIC Monitor Set or Stage configuration, as needed.
Who Is It For?
• Music students building monitoring habits.
• Creators who need a stable, unbiased reference.
• Arrangers, editors, and pre-production workflows.
• Anyone who monitors for long hours and needs consistency across devices.
