DA7.2
Two-channel, 7800W @ 4Ω Digital Power Amplifier, 90V-260V Universal Power
Power and Reliability.
In designing the DA Series we created a stable, energy-efficient, low-current drawing series of amplifiers designed to meet the demands of 21st-century AV installers 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.

• Universal power handles 90V-260V
• Signal & Power Indicators
• Light-weight Class D circuitry
• 1U Rackspace
• Electronically balanced XLR inputs and SPEAKON outputs
• Precision Rotary level controls and power switch.
