Product Description
FEATURES
- Switch-mode power supply for high performance and compact size
- Class D (digital) output for extremely high efficiency because of less current consumption and heat dissipation
- Easily handles 2-ohm loads all night long
- Variable speed fan for low noise
- Balanced XLR audio input / Speakon Speaker output
- Switch for mono and stereo at the back
- Comprehensive front panel indicators including signal (SIG), clip (CLIP), active (ACT) and, protect (PRO)
- Fully protected circuit design including DC, infrasonic, high frequency, thermal overload and short circuit
- Clip limiter - prevents severely clipped waveforms from reaching the loudspeakers, whilst maintaining full peak power
- DC protection - protects against infrasonic signals
- VHF protection - protects the loudspeakers against strong very high frequency non-musical signals above the audible range.
- Thermal protection - prevents the amplifier from being overheated.
- Compact size - only 1 U for reduced rack cost and space
- Light weight - only 9 kg for easier racking and shipping (bigger power model)
