DETAILS

The UP 4S is a discreet ceiling speaker that operates at 70V, 100V and Low Impedance, delivering clear, consistent sound in commercial spaces with easy installation and versatile performance options. 

The Up 4S offers a sleek and unobtrusive solution for delivering exceptional audio performance in various commercial settings. Whether it's hotels, retail spaces, bars, or restaurants, the Up 4S ensures consistent coverage and crystal-clear sound reproduction, catering to diverse environments while mindful of cost considerations.

With its integrated fixing system, installation is a breeze, ensuring a seamless and tidy setup. Encased in a neutral white finish with a perforated steel grille, the Up 4S features a shallow steel back which is perfect for ceilings with minimal cavity depth, blending effortlessly into any decor.

Powered by a 4" (105mm) driver, this speaker excels in both background music and speech projection. Its wide conical 150° coverage pattern ensures uniform sound dispersion throughout the designated area and makes it exceptionally well suited to low ceilings.

Versatility is key with the Up 4S, as it can operate on a series of 70 or 100 Volt taps or at low impedance, providing flexibility in system configuration. Tap selection is conveniently managed via a rotary switch discreetly located behind the removable grille.

For optimal performance and speaker protection, pairing the Up 4S with SmartAmps or Zone systems is recommended. With the Zone series, incorporating a ZonePad and utilizing the WebApp simplifies system setup and offers intuitive control for end users, enhancing overall user experience.
