For fixed installations, in addition to an unobtrusive appearance, the flexibility and versatility of the mixing amplifier are particularly important. It must be possible to connect various signal sources and microphones. In an emergency, it must be possible to simply mute the input signals to enable announcements or emergency calls. With the IMA 240, LD Systems presents a new mixer amplifier from the IMA series that leaves nothing to be desired in terms of design and flexibility.
Its compact design in a 9.5-inch housing, a wide range of connection options including Bluetooth for wireless connection of music sources, and a multi-level priority circuit guarantee seamless integration into commercial and industrial applications. The IMA 240 offers four priority levels for emergency calls and microphone/line inputs for various signal and music sources. Optionally, an automatic standby mode can be activated to further reduce power consumption.
The mixer amplifier has two priority contact closures: one for the emergency input, which mutes all other signal sources in the device, and one for the microphone inputs, which mutes the music signal sources. The outputs offer 240 W at 4 ohms, a 2-band EQ for bass and treble, and a 70 V / 100 V tap. The High-Z / Low-Z selector switch can be used to completely disconnect the output signal from the output transformer, ensuring optimal frequency response in low-input-impedance applications. External power amplifiers, active subwoofers or systems for music on hold can be combined with the IMA 240 via the integrated aux output. The music mix selector switch allows you to decide whether the entire mix or only the selected music signal source should be transmitted to the aux output.
The intuitive design of the control panel with capacitive buttons for selecting the music signal source, the clear layout of the rear panel and the compact 9.5-inch format ensure that no problems arise when installing the mixing amplifier.
