Product Details

 

DP digital amplifier is the first generation digital amplifier. With years of improvement, it becomes the most stable amplifier that can give you continual power without any problem.

 

 

Product Description

Digital switching amplifier
Rock-solid, ultrastable output power set record marks in terms of flexibility, efficiency and practical use. Whole amp racks of multiple conventional power amplifiers with switching power supplies may be reduced to a mere one to three LEX Class D Digital amplifiers. Apart from these "hard" benefits, they offer many more advantages such as a strikingly audiophile sound reproduction with very precise, deep lows and a superb resolution of midrange and high frequencies.
The fact that LEX develops and builds amplifiers in top-notch quality is almost self-explanatory. The uncompromising component selection and a circuit design based on criteria of aerospace technology ensure utmost reliability.
Features:
Ø Switch-mode power supply for high performance and compact size
Ø Class D (digital) output for extremely high efficiency because of less current consumption and heat dissipation
Ø Easily handles 2-ohm loads all night long
Ø Variable speed fan for low noise
Ø Balanced XLR audio input / Speakon Speaker output
Ø Switch for mono and stereo
Ø Comprehensive front panel indicators including signal (SIG), clip (CLIP), active (ACT) and, protect (PRO)
Ø Fully protected circuit design including DC, infrasonic, high frequency, thermal overload and short circuit
Ø Clip limiter - prevents severely clipped waveforms from reaching the loudspeakers, whilst maintaining full peak power
Ø DC protection - protects against infrasonic signals
Ø VHF protection - protects the loudspeakers against strong very high frequency non-musical signals above the audible range.
Ø Thermal protection - prevents the amplifier from being overheated
Ø Compact size - only 1 U for reduced rack cost and space
Ø Light weight - only 9 kg for easier racking and shipping (bigger power model)
