Jabra PanaCast 50 video bar system
The HORIZON VHA118SND vertical horizontal active subwoofer delivers exceptional low-frequency performance, designed to maintain high sound pressure levels over extended periods. Leveraging BEM finite element analysis, FBT has precisely optimised the woofer load volume, while the grille and protective fabric have been engineered to reduce acoustic impedance, resulting in enhanced output. The HORIZON VHA118SND extends system frequency response down to 30Hz and supports ground-stacked operation via integrated mounting hardware. Central to the design is an 800 plus 400 watt RMS amplifier with a TCP IP network interface, fully compliant with the OCA ALLIANCE AES70 protocol. This allows 24-bit 48 to 96kHz digital audio transmission over DANTE-compatible systems, with remote control enabled through the INFINITO System Management Suite. Housed in a robust aluminium chassis with smart forced-air cooling, the module includes an OLED display with encoder and a daylight-visible blue LED for easy device identification. The entire system has been developed in-house by FBT’s engineering team.
The HORIZON VHA118SND is a vertical horizontal active subwoofer engineered to deliver consistent, high-SPL low-frequency output across demanding professional audio applications. Designed by FBT for integration within the HORIZON system range, the HORIZON VHA118SND extends system frequency response down to 30Hz, supporting applications in touring, live sound reinforcement, and fixed installations that require powerful bass performance. This subwoofer benefits from finite element modelling (BEM) to optimise the load volume and minimise acoustic impedance, achieving superior acoustic efficiency and clarity. Constructed for durability and consistent performance, the HORIZON VHA118SND supports ground-stacked configurations through its integrated mounting system, providing installation flexibility.
A key component of this model is its 800 plus 400 watt RMS amplifier module, which incorporates a TCP IP network interface and operates using the AES70 protocol under the OCA ALLIANCE. This enables high-resolution 24-bit, 48 to 96kHz digital audio over DANTE networks and full remote system management via the INFINITO software suite. The amplifier is enclosed within a thermally stable aluminium chassis with active ventilation and includes an OLED display with encoder for on-device adjustments. A high-visibility blue LED aids identification in varied lighting conditions. Fully developed by FBT’s R&D team, the HORIZON VHA118SND reflects a focus on reliability, control, and precise sound reinforcement capabilities in high-demand professional environments.
