H_2×AUDIO I/O CARD | Carte d'Entrée/Sortie Audio Novastar H | XLR Professionnel

The Novastar H_2×AUDIO I/O CARD is a high-performance expansion module designed for the seamless integration of professional audio within the Novastar H-Series ecosystem. This card provides two balanced analog audio inputs and two outputs, ensuring that your high-resolution LED displays are complemented by synchronized, high-fidelity sound. Engineered for the demanding requirements of fixed installations and live events, it eliminates latency issues by aligning video processing with audio feeds. Whether managing large-scale pixel maps across multiple LED cabinets or driving a single high-brightness screen, this module maintains the integrity of your multimedia signals. Its professional XLR/terminal connectivity ensures low-noise transmission, making it a critical component for any comprehensive video wall controller setup. By bridging the gap between professional sound desks and LED video processors, Pixelight offers a streamlined solution for complex audiovisual workflows.

Professional Audio Integration for Modular LED Controllers

In the world of high-end LED displays, visual performance—measured by narrow pixel pitches, high nits, and ultra-high refresh rates—is only half of the story. The Novastar H_2×AUDIO I/O CARD addresses the critical need for signal synchronization. Unlike standard consumer interfaces, this card utilizes professional-grade analog circuitry to ensure that your audio matches the high-speed processing of the H-Series chassis.

Advanced Signal Processing and Synchronization

• Lip-Sync Accuracy: By processing audio within the same hardware environment as the video stream, the H_2×Audio card minimizes the delay typically found in external processing chains, ensuring perfect alignment with high-refresh-rate visuals.
• Hot-Swappable Reliability: Like all H-Series modules, this card supports hot-swapping. This is essential for rental applications and mission-critical 24/7 control rooms where downtime is not an option.
• Low Noise Floor: The balanced I/O architecture rejects electromagnetic interference, preserve the signal purity even in environments crowded with LED power supplies and wireless transmitters.

By integrating this card, technicians can manage audio routing directly through the Novastar management software, providing a centralized control point for both the visual SMD/GOB matrix and the accompanying soundscape.

Versatile Applications in Professional AV

The Novastar H_2×AUDIO I/O CARD is indispensable across various high-end installation scenarios:

• Broadcasting & Virtual Production (xR): Essential for ensuring that the audio from talent is perfectly synced with the background rendered on GOB or SMD LED walls, preventing "lip-sync" errors during live broadcasts.
• Corporate Boardrooms & Auditoriums: Facilitates the connection of the main LED video processor to the house PA system, allowing for seamless multimedia presentations.
• Live Concerts & Touring: Provides a robust interface for FOH (Front of House) engineers to feed audio into the video stream for monitoring or distribution across large-scale event screens.
• Control Rooms: Allows for audio alerts and communication feeds to be managed through the same modular hardware used for the 24/7 video monitoring wall.

Technical Implementation and Optimization

To achieve the best results with your H_2×AUDIO I/O module, consider the following technical recommendations:

• Signal Integrity: Use high-quality shielded twisted-pair cables for the XLR connections to prevent interference from the PWM frequencies of the LED drivers and high-current power cables.
• Gain Staging: Properly calibrate the input levels within the H-Series interface to avoid clipping. Ensure your mixer output matches the professional line-level sensitivity of the card.
• Latency Management: When using advanced features like HDR or low-latency mode on your LED receiving cards (such as the A10s Pro), use the H-Series internal delay settings to fine-tune the audio-to-video offset.
• Maintenance: Periodically check the physical seating of the card in the H-series frame. Since the module is hot-swappable, ensure the thumbscrews are tightened to maintain a solid ground connection.
