 The
DA Series multi-channel digital power amplifiers are 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
single or dual rack-space design and ultra-low heat dissipation allow
designers to rack-mount up to five units without open space between units.
The DA Series is comprised of high and low impedance
four-channel models each equipped with an independent power supply for each
channel to assure continuous operation and unmatched reliability and
performance. Other features include recessed stepped attenuators for precise
gain calibration, removable dust filters for easy maintenance, and optional
isolation transformer.
Competitively priced, the new DA Series multi-channel
power amplifiers are backed by TOA’s five-year warranty.
