Permanent installations require solutions which offer a visually discrete design that blends into the background while still being flexible and versatile in their functions. You need to be able to connect different audio sources and manage them, to mute non-priority signals during announcements or emergency calls. With IMA® 30, LD Systems presents the first model of the new IMA® mixing amplifier-series, which leaves nothing to be desired in terms of design and flexibility. Seamless integration with IMA® 30 is a sure thing in both industrial and commercial applications thanks to the compact 9.5-inch housing design, an array of connection possibilities, including Bluetooth for wireless connection of Audio and a multistage priority circuit. IMA® 30 is equipped with four priority levels to manage all connected audio signals during emergency or priority announcements. An automatic standby mode can also be activated to reduce power consumption during absence of audio signal. The mixing amplifier features two priority contact closures: one for emergency input to mute both Mic/Line and music sources, and one for Mic/Line Channels to mute music sources only. The outputs provide 30 W of power at 4 Ohm, a two-band equalizer for bass and trebles as well as 70 V/100 V tap settings. The Hi-Z and Lo-Z selector switch lets you separate the output signal completely from the output transformer to ensure an optimal frequency response for low impedance applications. The built-in aux output can be used to add external power amplifiers, active subwoofers or on-hold music systems to the IMA® 30. You can also choose to send the entire mix or only the selected music signal source to the aux output using the music-mix selector switch. Installation mixing amplifier

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.
