Project Overview
Roseberys London, a prestigious fine art auction house, required a versatile audio solution for their gallery spaces. The system needed to serve a dual purpose: providing background music during general gallery hours, and functioning as a clear, professional PA system to support talks and discussions for audiences of between 20 and 60 people.
The two key areas of the gallery presented slightly different challenges. Rooms 2, 3 and 5 combine to form approximately 80 square metres with 4 metre high ceilings, while the lower ground area - rooms 7 and the adjacent space - covers around 70 square metres with 3 metre high ceilings. Audio Volt designed a system that would deliver consistent, even sound coverage across both areas, while remaining simple and intuitive for gallery staff to operate.
The Sound System Explained
At the heart of the system is the Adastra RM4460, a flexible 4-zone mixer amplifier offering 240W of power. Its built-in Bluetooth, FM tuner and USB playback make it straightforward for staff to stream or play background music without the need for additional equipment. The four-zone capability allows independent volume control across the different gallery spaces, giving the team full flexibility depending on which rooms are in use.

Fonestar SONORA-4TB Speakers
Eight of these compact, discreet wall-mounted speakers were distributed across the gallery spaces to provide even sound coverage throughout. Their clean white finish ensures they complement the gallery's aesthetic without drawing attention away from the artwork on display. Despite their compact size, the SONORA-4TB delivers clear, well-balanced audio suitable for both background music and spoken word.

To support presentations and gallery talks, the Chord XU2 dual wireless microphone system was included, providing two independent lapel microphone channels. This allows two speakers, such as an auctioneer and a guest expert to move freely around the gallery while addressing the audience clearly and without the restriction of cables. The UHF wireless system ensures a reliable, interference-free signal throughout the event.

AudioKraft Apollo Speaker Cable
A 100-metre drum of AudioKraft Apollo speaker cable was used throughout the installation, providing high-quality, reliable connections between the amplifier and all eight wall speakers across both floors of the gallery.
