About this model
Professional wireless systems should simplify deployment without compromising audio quality, security or scalability. The Audix Novacore NC4HEC quad-channel handheld wireless system was created to provide a complete solution for performers, presenters and production teams who require dependable wireless performance across multiple channels. Pairing the NCR4 quad-channel receiver with four NCHH handheld transmitters and four NCEC extended cardioid capsules, it delivers natural vocal reproduction, low-latency digital audio and AES-256 encrypted wireless transmission in one integrated package. From houses of worship and theaters to corporate events, broadcast facilities and concert productions, the NC4HEC provides the clarity, flexibility and reliability required for demanding professional wireless applications. Complete Four-Channel Handheld System Simplifies Setup The NC4HEC includes everything needed to deploy four professional handheld wireless channels in a single package. Each NCHH transmitter pairs quickly with the NCR4 receiver using one-touch infrared synchronization, while onboard frequency scanning identifies clean operating channels across the system's 48MHz UHF tuning range. Digital diversity reception supports stable operation in demanding RF environments, and the Novacore platform accommodates up to 24 simultaneous wireless systems per frequency band for larger productions. Detachable BNC antennas, USB-C charging cables and a universal power supply complete a package prepared for professional use. Extended Cardioid Capsules Deliver Natural Vocal Clarity Each included NCEC capsule was engineered to provide consistent vocal tone across a wide range of working distances, allowing performers to move naturally without significant changes in sound. Audix's proprietary Very Low Mass (VLM) diaphragm technology delivers fast transient response, capturing vocal detail, articulation and presence with impressive accuracy. The extended cardioid pickup pattern offers strong off-axis rejection while maintaining predictable tonal balance, making the system well suited for lead vocalists, presenters and worship leaders who require dependable feedback control. The interchangeable capsule design also allows users to swap to compatible Novacore capsule options without tools as performance needs evolve. Secure Digital Audio Maintains Professional Performance The NCR4 receiver processes audio at 24-bit/44.1kHz resolution with greater than 110dB of dynamic range, preserving natural vocal detail across all four wireless channels. Latency remains below 3 ms for seamless live performance, while AES-256 encryption protects every transmission for corporate, government and broadcast environments where secure communication is essential. Digital diversity reception and excellent RF rejection support dependable operation in increasingly crowded wireless environments, helping engineers maintain reliable audio throughout every event. Professional Connectivity Supports Modern Workflows Balanced XLR outputs provide straightforward integration with traditional analog consoles, while integrated Dante/AES67 networking routes all four wireless channels through a single Ethernet connection for streamlined digital audio workflows. Front-panel LCD displays provide continuous monitoring of RF and audio levels, battery status, diversity operation and transmitter information, while a dedicated headphone output supports direct channel monitoring during setup and operation. Dual RJ11 ports also allow multiple receivers to connect to Audix Frequency Coordination software through a daisy chain, simplifying deployment of larger wireless systems. Built to Grow With Your Wireless System Each NCHH handheld transmitter operates for more than nine hours using either two AA batteries or an optional rechargeable NCLB lithium-ion battery pack, with convenient USB-C charging built directly into the transmitter body. The modular Novacore platform allows additional receivers, transmitters and interchangeable microphone capsules to be added as channel counts and production requirements increase. Combining premium vocal performance with advanced digital wireless technology, the Audix Novacore NC4HEC quad-channel handheld wireless system provides a complete solution for demanding live sound, worship, corporate and broadcast applications.
