The Qi-Series comprises loudspeakers and hardware fittings specifically targeted for fixed installation use. They can be colour matched to interior designs and protected for use in climatically hostile environments. Based on the d&b Q-Series and similarly maintaining the maxims of the d&b System reality, they are ideally suited for speech and music in many theatre, conference and orchestral situations where multiple open microphones are used and considerable gain before feedback is an absolute requirement. Accurate performance data for industry standard simulation software allows the installation designer to create solutions that are predictable and reliable for a wide range of application settings, from the smallest to the largest venue.
