SonARC and DSP Features
The amplifier incorporates SonARC (Sonance Advanced Room Correction) for optimal sound. This system provides access to hundreds of EQ presets specifically designed for Sonance speakers, accessible through intuitive menus. For advanced users, a 10-band parametric EQ is available for fine-tuning the audio performance to any specific acoustic environment.
Access to SonARC and DSP settings is typically done via a network connection and a dedicated software interface or web-based control panel. Refer to the detailed software manual for comprehensive instructions on configuring these advanced features.
Maintenance and Care
To ensure the longevity and optimal performance of your Sonance DSP 2-750 MKII amplifier, follow these maintenance guidelines:
- Cleaning: Use a soft, dry cloth to clean the exterior surfaces. Do not use liquid cleaners or aerosol sprays, as they may damage the finish or internal components.
- Ventilation: Regularly check that the ventilation openings are clear of dust and debris. Blocked vents can lead to overheating.
- Connections: Periodically inspect all cable connections to ensure they are secure and free from corrosion.
- Storage: If storing the amplifier for an extended period, disconnect it from power and store it in a cool, dry place, away from direct sunlight and extreme temperatures.
