Description

IMA 120

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 120, LD Systems presents a new model of the IMA® mixing amplifier-series, which leaves nothing to be desired in terms of design and flexibility.

Seamless integration with IMA 120 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 120 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 120 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 120. 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.
