TOA POWER AMPLIFIER 4x550W 4Ω

The new DA Series digital multi-channel amplifiers are the latest addition to the TOA line of industry-standard audio products for installed sound. The DA Series is ideal for multi-zone distributed speaker systems and professional sound applications.

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.
