CLASS D POWER AMPLIFIER DA8.4
$1,282.27
In designing the new DA Series we created a stable, energy-efficient, low current drawing series of amplifiers designed to meet the demands of 21st century AV installaters and audio professionals.
While safe and stable with 2 Ω loads, the DA series is optimized for 4 Ω loudspeakers. Using the same overall concept of power and stability, the D series occupies only a single space in a 19” rack, yet at even less depth, and weighs a fraction of other amplifiers models.
With its simple interface, versatility, usability along with its sonic performance, the DA series represents a highly attractive mix at an exceptionally great value for almost any AV or sound professional. No matter what type of loudspeaker it is connected to, these amplifiers is bound to become one of the best-selling amplifier models in the entire Sound Barrier range.
• Handles 2 Ohm loads
• Universal power handles 90V-260V
• Signal & Power Indicators
• Light-weight Class D circuitry
• 1U Rackspace
• Electronically balanced XLR inputs and SPEAKON outputs per channel.
• Precision Rotary level controls and power switch.
