  • Engineered with Class D technology, the new DA Series amplifiers operate at 85 percent efficiency and consume almost one-third less power than conventional analog amplifiers. The compact and lightweight (14.6 lbs.) single rack-space design and ultra-low heat dissipation allow designers to rack-mount up to five units without open space between units.

    Equipped with an independent power supply for each channel, the new multi-channel amplifiers offer unmatched reliability and performance. Other features include recessed stepped attenuators for precise gain calibration, removable dust filters for easy maintenance, and optional isolation transformer.
