The 4420A packs the power and flexibility of Smart IP technology into an ultra-compact enclosure, bringing clarity, intelligibility and uniform room coverage to the tightest of spaces.
Power to the speaker
Combining class-leading sound quality with single cable convenience, the 4420 uses PoE to produce uncompromised acoustic performance, and is fully compatible with both Dante and open streaming standards such as AES67. Producing huge sound from a tiny footprint, the 4420 delivers 100 dB of maximum SPL and low frequency extension right down to 55 Hz.
Power to the installer
As part of the Smart IP family, the 4420 integrates tightly with our Smart IP Manager software – which allows installers to configure an almost unlimited number of rooms, zones, loudspeakers and audio channels, and includes device discovery, a versatile room EQ tool set, system organisation and status monitoring. After which, a public API command set allows the 4420 to be integrated into house automation systems for day to day use. Easy.
Key Technologies
The speaker combines advanced networking, power, and acoustic technologies to deliver flexible, reliable, and high-quality audio performance. Audio-over-IP (AoIP) enables digital audio transmission over network infrastructure, while PoE Power simplifies installation by allowing power and data to be delivered through a compatible network connection. Smart IP Manager provides convenient system configuration and management.
Active Crossovers ensure precise frequency separation, while Directivity Control Waveguide (DCW™) Technology provides controlled and consistent sound dispersion. Intelligent Signal Sensing (ISS™) Technology enables efficient signal detection, and Minimum Diffraction Enclosure (MDE™) Technology helps minimise unwanted cabinet-related acoustic effects. Optimised Amplifiers deliver clean and efficient power, while Protection Circuitry helps safeguard the speaker during demanding operation. Reflex Port Design enhances low-frequency performance, and Versatile Mountings provide flexible installation and placement options.
