| Content | PA amplifier / paging system, 480W, 5 speaker zone attenuator, slot module, 3 x mic/line-in, 3 x line-in, priority switch, built-in chime
This series of amplifiers always has the same output point: your music is distributed to a maximum of 5 zones, which may or not be interrupted to put out a call.
For each zone, the volume can be controlled separately. Connection to an alarm system or telephone switchboard can be made in an instant. In short, the ideal all-in formula.

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.
The first phase of the DA Series is comprised of two models; the high-impedance DA-250FH provides four 100 Volt output channels of 250 Watts. The low-impedance model DA-250F provides four channels of 250 Watts at four ohms or two channels of 500 Watts at eight ohms in bridged mode. Additional models are scheduled to be launched in 2007.
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.
