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 60, 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.
