Description

The VHA 118 series are processed active subwoofers equipped with a 460mm (18") high-excursion woofer and a 2500W Class D amplifier. They are designed for professional sound reinforcement, offering high SPL and versatile configuration options. The VHA 118SND and 118.2SA models include network interfaces (TCP/IP, AES70), while the 118SN model lacks Dante functionality.

Controls and Functions

The rear panel features an OLED display and a push-encoder for parameter adjustment. Key functions include:

• DSP Menu: Access presets, delay, phase, and routing settings.
• Presets: Select from Original, Deep, Punch, Infra, and Cardioid configurations to match your acoustic environment.
• Networking: Connect via Ethernet for remote control. Supports Star, Daisy Chain, and Mixed topologies.
• Status LEDs: Monitor system health (Green: ON, Yellow: Standby, Red: Fan Error/Protection).

Installation and Networking

Ground Stacking: You can stack up to 3 modules above the subwoofer using dedicated accessories like the VHA-B 406 or MS-F 210. Always ensure the stack is secure.

Cardioid Configurations: Useful for reducing low-frequency energy on stage. Requires specific positioning of rear-facing and front-facing subwoofers. Refer to the manual's diagrams for correct placement.

Networking: Use CAT5e or higher cables. The system supports daisy-chaining up to 8 devices per group. In case of a network failure, the hardware bypass ensures downstream devices remain controllable.

Maintenance and Safety

• Cleaning: Use only a dry cloth.
• Ventilation: Do not block ventilation openings.
• Fan Error: If the red LED indicates a fan error, check if the fan is free to spin; it may require replacement.
