The SM Professional DH 64 is a high-performance 4 channel digital hybrid power amplifier.
Integrating an innovative “Tracking Class D” (TD) circuit design, the amplifier delivers efficiency of Class D technology with the sonic punch of class AB amplification and immense power, drive, definition and dependability.
Features
- Innovative “Tracking Class D” (TD) circuit design to deliver high drive, definition and dependability.
- Delivers efficiency of Class D technology with the sonic punch of class AB amplification.
- High-current toroidal transformers with high-endurance cores for superior transient response.
- 3 switchable operational modes: stereo, parallel, and bridge.
- Low THD and high damping factor for excellent sound quality.
- Built-in limiter circuit for speaker protection from damage due to distorted input signals.
- Protection devices: temperature, VHF, DC, short circuit, soft-start and overload.
- Intelligent cooling and heat dissipation using dual variable speed CFM fans.
- 3-colour LED bargraph to indicate power ON, signal (5-segments), limit and protect status.
- Audio-grade balanced XLR input connectors.
- High-performance Speakon output connectors.
- Wide mains voltage operation 150-240V AC.
- Minimum wiring and standardised layout for easy serviceability.
