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)
